HYBRIT partners start building underground fossil-free hydrogen storage facility in Luleå

SSAB, LKAB and Vattenfall have commenced building a rock cavern storage facility for fossil-free hydrogen gas on a pilot scale next to the HYBRIT pilot facility for direct reduced iron in Luleå, northern Sweden.

This is an important step in the development of a fossil-free value chain for fossil-free steel, the companies said, with the investment of just over SEK250 million ($29 million) divided equally across the holding companies and the Swedish Energy Agency, which provides support via Industriklivet.

As part of the SSAB, LKAB and Vattenfall joint HYBRIT initiative, Hybrit Development AB is starting the construction of a hydrogen storage facility in Svartöberget to develop the technology for storage.

Fossil-free hydrogen, which will replace coal and coke, is a crucial part of the production technique for fossil-free iron and steel production, where emissions of carbon dioxide will be virtually eliminated, the companies said. Hydrogen can be produced cost effectively through the electrolysis of water using fossil-free electricity. The hydrogen produced by the electrolysers can be used immediately or stored for later use.

Hydrogen storage is predicted to play a very important role in future power and energy balancing, and in large-scale hydrogen production, according to the companies. The storage facility is expected to be operational from 2022-2024.

Andreas Regnell, Head of Strategy at Vattenfall and Chairman of the Board at HYBRIT, said: “We’re really pleased that HYBRIT is continuing to lead the development of efficient production for fossil-free steel, as we’re now also building a pilot storage facility for large-scale fossil-free hydrogen in Luleå.

“Storage provides the opportunity to vary demand for electricity and stabilise the energy system by producing hydrogen when there’s a lot of electricity, for example in windy conditions, and to use stored hydrogen when the electricity system is under strain.”

Martin Pei, Technical Director of SSAB and Board member of HYBRIT, said: “By developing a method for hydrogen storage and securing access to fossil-free electricity, we’re creating a value chain all the way out to customers where everything is fossil-free – from the mine to the electricity and to the finished steel. This is unique.”

The 100 cu.m hydrogen storage is being built in an enclosed rock cavern around 30 m below ground. Building the storage facility underground provides opportunities to ensure the pressure required to store large amounts of energy in the form of hydrogen in a cost-effective way, the companies said.

The technology used is adapted to Scandinavian bedrock conditions and will be further developed to handle the storage of hydrogen.

The storage facility is based on proven technology and the hydrogen is used in the plant’s direct reduction reactor to remove oxygen from iron ore pellets, the companies said. The fossil-free sponge iron resulting from the process is then used as a raw material in the manufacture of fossil-free steel.

Industrialisation of fossil-free steel under the HYBRIT initiative is intended to start with the first demonstration plant, which will be ready in 2026, for the production of 1.3 Mt of fossil-free sponge iron in Gällivare, Sweden. The goal is to expand sponge iron production to a full industrial scale of 2.7 Mt/y by 2030 to be able to supply SSAB, among others, with feedstock for fossil-free steel.

HYBRIT partners choose Gällivare for fossil-free sponge iron demonstration plant

SSAB, LKAB and Vattenfall say they are taking a new, decisive leap forward in their work on HYBRIT, with the trio selecting Gällivare, in northern Sweden, as the location of the first production plant for its fossil-free sponge iron exercise.

Industrialisation is intended to start with the first demonstration plant, which will be ready in 2026, for the production of 1.3 Mt of fossil-free sponge iron in Gällivare. The demonstration plant will be integrated with iron pellet making and is part of LKAB’s transition plan.

The goal is to expand sponge iron production to a full industrial scale of 2.7 Mt by 2030 to be able to supply SSAB, among others, with feedstock for fossil-free steel. The choice of Gällivare for the demo plant was based on a joint assessment of industrial synergies, where proximity to iron ore, logistics, an electricity supply and energy optimisation were important factors, the companies said.

There are many advantages to locating the new sponge iron plant in Gällivare, which is also near LKAB’s mining production and processing plants. Using iron ore pellets that are already warm in the process will save huge amounts of energy, according to the companies. On top of this, 30% of weight will be eliminated from transport since hydrogen gas will be used to remove the oxygen in the iron ore. Gällivare also offers good access to fossil-free electricity from Vattenfall.

Martin Lindqvist, President and CEO at SSAB (centre), said: “We are world leaders in the work to transform the steel industry and are now stepping up the pace. We are doing this for the climate, customers, competitiveness and for employment. That we are now raising ambitions for a completely fossil-free value chain is unique and a message of strength from SSAB and our HYBRIT partners. We are seeing a clear increase in demand for fossil-free steel and it is right to speed up our ground-breaking cooperation.”

Jan Moström, President and CEO at LKAB (left), said the companies are leading the transformation of the iron and steel industry.

“The whole process starts with top quality iron ore in the mine and our transition plan gives strong economies of scale that pave the way for the competitive production of fossil-free steel by our customers,” he said. “This is the greatest thing we can do together for the climate. Once we are ready, we will reduce the global emissions of our customers by 35 Mt a year, which is equivalent to triple the effect of parking all passenger cars in Sweden for good.”

At the same time as announcing the Gällivare demo plant, SSAB and LKAB have agreed to deepen their partnership to create the “most effective fossil-free steel value chain from mine to steel, to customer”, they said.

“We will support and enable each other’s transformation, with Vattenfall an enabler of the huge need for electricity and hydrogen gas,” they said. “On the back of an acceleration of HYBRIT, together with LKAB’s strategy and deeper partnership, SSAB will now explore the prerequisites to convert to fossil-free steel production in Luleå faster than planned.”

The plan to convert its Oxelösund steel works in 2025 remains unchanged, as does its goal to be the first to market, in 2026, with fossil-free steel, SSAB clarified.

Anna Borg (right), President and CEO at Vattenfall, added: “Sweden and HYBRIT have a world-leading position in making fossil-free iron- and steelmaking a reality and the initiative will now be further scaled up. That fossil-free electricity and ground-breaking processes will in principle help to eliminate climate-affecting emissions completely from iron- and steelmaking is a flagship example of Vattenfall’s strategy to enable a fossil-free life within a generation. It is now extra important that the permit processes can deliver at the same pace as fossil-free steelmaking.”

Hybrit Development AB, which is owned by SSAB, LKAB and Vattenfall, is developing the technology to make steel using hydrogen gas instead of coal, which will minimise climate harmful carbon dioxide emissions from production. The HYBRIT pilot plant will be able to make fossil-free sponge iron to make fossil-free steel for prototypes to customers already in 2021.

The partners claim the initiative has the potential to reduce carbon dioxide emissions by 10% in Sweden and 7% in Finland, as well as contribute to cutting steel industry emissions in Europe and globally.

North sets Ferrexpo on a course for ‘carbon neutrality’

Ferrexpo is used to setting trends. It was the first company to launch a new open-pit iron ore mine in the CIS since Ukraine gained its independence in 1991 and has recently become the first miner in Ukraine to adopt autonomous open-pit drilling and haulage technology.

It plans to keep up this innovative streak if a conversation with Acting CEO Jim North is anything to go by.

North, former Chief Operating Officer of London Mining and Ferrexpo, has seen the technology shift in mining first-hand. A holder of a variety of senior operational management roles in multiple commodities with Rio Tinto and BHP, he witnessed the take-off of autonomous haulage systems (AHS) in the Pilbara, as well as the productivity and operating cost benefits that came with removing operators from blasthole drills.

He says the rationale for adopting autonomous technology at Ferrexpo’s Yeristovo mine is slightly different to the traditional Pilbara investment case.

“This move was not based on reduction in salaries; it was all based on utilisation of capital,” North told IM. While miners receive comparatively good salaries in Ukraine, they cannot compete with the wages of those Pilbara haul truck drivers.

Ferrexpo Acting CEO, Jim North

North provided a bit of background here: “The focus for the last six years since I came into the company was about driving mining efficiencies and getting benchmark performance out of our mining fleet. This is not rocket science; it is all about carrying out good planning and executing to that plan.”

The company used the same philosophy in its process plant – a philosophy that is likely to see it produce close to 12 Mt of high grade (65% Fe) iron ore pellets and concentrate next year.

Using his industry knowledge, North pitted Ferrexpo’s fleet performance against others on the global stage.

“Mining is a highly capital-intensive business and that equipment you buy has got be moving – either loaded or empty – throughout the day,” North said. “24 hours-a-day operation is impossible as you must put fuel in vehicles and you need to change operators, so, in the beginning, we focused on increasing the utilised hours. After a couple of years, I noticed we were getting very close to the benchmark performance globally set by the majors.

“If you are looking at pushing your utilisation further, it inevitably leads you to automation.”

Ferrexpo was up for pushing it further and, four years ago, started the process of going autonomous, with its Yeristovo iron ore mine, opened in 2011, the first candidate for an operational shakeup.

“Yeristovo is a far simpler configuration from a mining point of view,” North explained. “It is basically just a large box cut. Poltava, on the other hand (its other iron ore producing mine currently), has been around for 50 years; it is a very deep and complex operation.

“We thought the place to dip our toe into the water and get good at autonomy was Yeristovo.”

This started off in 2017 with deployment of teleremote operation on its Epiroc Pit Viper 275 blasthole drill rigs. The company has gradually increased the level of autonomy, progressing to remotely operating these rigs from a central control room. In 2021-2022, these rigs will move to fully-autonomous mode, North says.

Ferrexpo has also been leveraging remotely-operated technology for mine site surveying, employing drones to speed up and improve the accuracy of the process. The miner has invested in three of these drones to carry out not only site surveys, but stockpile mapping and – perhaps next year – engineering inspections.

“The productivity benefits from these drones are huge,” North said. “In just two days of drone operation, you can carry out the same amount of work it would take three or four surveyors to do in one or two weeks!”

OEM-agnostic solution

It is the haul truck segment of the mine automation project at Yeristovo that has caught the most industry attention, with Ferrexpo one of the first to choose an OEM-agnostic solution from a company outside of the big four open-pit mining haul truck manufacturers.

The company settled on a solution from ASI Mining, owned 34% by Epiroc, after the completion of a trial of the Mobius® Haulage A.I. system on a Cat 793D last year.

The first phase of the commercial project is already kicking off, with the first of six Cat 793s converted to autonomous mode now up and running at Yeristovo. On completion of this first phase of six trucks, consideration will be given to timing of further deployment for the remainder of the Yeristovo truck fleet.

This trial and rollout may appear fairly routine, but behind the scenes was an 18-month process to settle on ASI’s solution.

“For us, as a business, we have about 86 trucks deployed on site,” North said. “We simply couldn’t take the same route BHP or Rio took three or four years ago in acquiring an entirely new autonomous fleet. At that point, Cat and Komatsu were the only major OEMs offering these solutions and they were offering limited numbers of trucks models with no fleet integration possibilities.

“If you had a mixed fleet – which we do – then you were looking at a multi-hundred-million-dollar decision to change out your mining fleet. That is prohibitive for a business like ours.”

Ferrexpo personnel visited ASI Mining’s facility in Utah, USA, several times, hearing all about the parent company’s work with NASA on robotics. “We knew they had the technical capability to work in tough environments,” North remarked.

“We also saw work they had been doing with Ford and Toyota for a number of years on their unmanned vehicles, and we witnessed the object detect and collision avoidance solutions in action on a test track.”

Convinced by these demonstrations and with an eye to the future of its operations, Ferrexpo committed to an OEM-agnostic autonomous future.

“If we want to get to a fully autonomous fleet at some stage in the future, we will need to pick a provider that could turn any unit into an autonomous vehicle,” North said. It found that in ASI Mining’s Mobius platform.

Such due diligence is representative not only of the team’s thorough approach to this project, it also reflects the realities of deploying such a solution in Ukraine.

“It is all about building capability,” North said. “This is new technology in Ukraine – it’s not like you can go down the road and find somebody that has worked on this type of technology before. As a result, it’s all about training and building up the capacity in our workforce.”

After this expertise has been established, the automation rollout will inevitably accelerate.

“Once we have Yeristovo fully autonomous, we intend to move the autonomy program to Belanovo, which we started excavating a couple of years ago,” North said. “The last pit we would automate would be Poltava, purely due to complexity.”

Belanovo, which has a JORC Mineral Resource of 1,700 Mt, is currently mining overburden with 30-40 t ADTs shifting this material. While ASI Mining said it would be able to automate such machines, North decided the automation program will only begin when large fleet is deployed.

“When we deploy large fleet at Belanovo and start to move significant volumes, we intend for it to become a fully-autonomous operation,” he said.

Poltava, which is a single pit covering a 7 km long by 2 km wide area (pictured below), has a five-decade-long history and a more diverse mining fleet than Yeristovo. In this respect, it was always going to be harder to automate from a loading and haulage point of view.

“If you think about the fleet numbers deployed when Belanovo is running, we will probably have 50% of our fleet running autonomously,” North said. “The level of capability to run that level of technology would be high, so it makes sense to take on the more complex operation at Poltava at that point in time.”

Consolidation and decarbonisation

This autonomy transition has also given North and his team the chance to re-evaluate its fleet needs for now and in the future.

This is not as simple as it may sound to those thinking of a typical Pilbara AHS fleet deployment, with the Yeristovo and Poltava mines containing different ore types that require blending at the processing plant in order to sustain a cost-effective operation able to produce circa-12 Mt/y of high-grade (65%-plus Fe) iron ore pellets and concentrate.

“That limits our ability in terms of fleet size for ore mining because we want to match the capacity of the fleet to the different ore streams we feed into the plant,” North said.

This has seen the company standardise on circa-220 t trucks for ore movement and 300-320 t trucks for waste haulage.

On the latter, North explained: “That is about shovel utilisation, not necessarily about trucks. If you go much larger than that 320-t truck, you are talking about the need to use large rope shovels and we don’t have enough consistent stripping requirements for that. We think the 800 t-class electric hydraulic excavator is a suitable match for the circa-320 t truck.”

This standardisation process at Poltava has seen BELAZ 40 t trucks previously working in the pit re-assigned for auxiliary work, with the smallest in-pit Cat 777 trucks acting as fuel, water and lubrication service vehicles at Poltava.

“The Cat 785s are the smallest operating primary fleet we have at Poltava,” North said. “We also have the Hitachi EH3500s and Cat 789s and Cat 793s, tending to keep the bigger fleet towards Yeristovo and the smaller fleet at Poltava.”

In carrying out this evaluation, the company has also plotted its next electrification steps.

“Given we have got to the point where we know we want 220 t for ore and 300-320 t nominally for waste at Yeristovo, we have a very clear understanding of where we are going in our efforts to support our climate action,” North said.

Electrification of the company’s entire operation – both the power generation and pelletising segment, and the mobile fleet – forms a significant part of its carbon reduction plans.

A 5 MW solar farm is being built to trial the efficacy of photovoltaic generation in the region, while, in the pelletiser, the company is blending sunflower husks with natural gas to power the process. Fine tuning over the past few years has seen the company settle on a 30:70 sunflower husk:natural gas energy ratio, allowing the company to make the most of a waste product in plentiful supply in Ukraine.

On top of this, the company is recuperating heat from the pelletisation process where possible and reusing it for other processes.

With a significant amount of ‘blue’ (nuclear) or ‘green’ (renewable) power available through the grid and plans to incorporate renewables on site, Ferrexpo looks to have the input part of the decarbonisation equation covered.

In the pellet lines, North says green hydrogen is believed to be the partial or full displacement solution for gas firing, with the company keenly watching developments such as the HYBRIT project in Sweden.

On the diesel side of things, Ferrexpo is also charting its decarbonisation course. This will start with a move to electric drive haul trucks in the next few years.

Power infrastructure is already available in the pits energising most of its electric-hydraulic shovels and backhoes, and the intention is for these new electric drive trucks to go on trolley line infrastructure to eradicate some of the operation’s diesel use.

“Initially we would still need to rely on diesel engines at the end of ramps and the bottom of pits, but our intention is to utilise some alternative powerpack on these trucks as the technology becomes available,” North said.

He expects that alternative powerpack to be battery-based, but he and the company are keeping their options open during conversations with OEMs about the fleet replacement plans.

“We know we are going to have to buy a fleet in the next couple of years, but the problem is when you make that sort of purchase, you are committing to using those machines for the next 20 years,” North said. “During all our conversations with OEMs we are recognising that we will need to buy a fleet before they have probably finalised their ‘decarbonised’ solutions, so all the contracts are based on the OEM providing that fully carbon-free solution when it becomes available.”

With around 15% of the company’s carbon footprint tied to diesel use, this could have a big impact on Ferrexpo’s ‘green’ credentials, yet the transition to trolley assist makes sense even without this sustainability benefit.

“The advantages in terms of mining productivity are huge,” North said. “You go from 15 km/h on ramp to just under 30 km/h on ramp.”

This is not all North offered up on the company’s carbon reduction plans.

At both of Ferrexpo’s operations, the company moves a lot of ore internally with shuttle trains, some of which are powered by diesel engines. A more environmentally friendly alternative is being sought for these locomotives.

“We are working with rail consultants that are delivering solutions for others to ‘fast follow’ that sector,” North said referencing the project already underway with Vale at its operations in Brazil. “We are investigating at the moment how we could design and deploy the solution at our operations for a lithium-ion battery loco.”

Not all the company’s decarbonisation and energy-efficiency initiatives started as recently as the last few years.

When examining a plan to reach 12 Mt/y of iron ore pellet production, North and his team looked at the whole ‘mine to mill’ approach.

“The cheapest place to optimise your comminution of rock is within the mine itself,” North said. “If you can optimise your blasting and get better fragmentation in the pit, you are saving energy, wear on materials, etc and you are doing some of the job of the concentrator and comminution process in the mine.”

A transition to a full emulsion blasting product came out of this study, and a move from NONEL detonators to electronic detonators could follow in the forthcoming years.

“That also led us into thinking about the future crusher – where we want to put it, what materials to feed into the expanded plant in the future, and what blending ratio we want to have from the pits,” North said. “The problem with pit development in a business that is moving 150-200 Mt of material a year is the crusher location needs to change as the mining horizons change.”

It ended up becoming a tradeoff between placing a new crusher in the pit on an assigned bench or putting it on top of the bench and hauling ore to that location.

The favoured location looks like being within the pit, according to North.

“It will be a substantial distance away from where our existing facility at Poltava is and we will convey the material into the plant,” he said. “We did the tradeoff study between hauling with trains/trucks, or conveying and, particularly for Belanovo, we need to take that ore to the crusher from the train network we already have in place.”

These internal ‘green’ initiatives are representative of the products Ferrexpo is supplying the steel industry.

Having shifted away from lower grade pellets to a higher-grade product in the past five years and started to introduce direct reduced iron pellet products to the market with trial shipments, Ferrexpo is looking to be a major player in the ‘green steel’ value chain.

North says as much.

“We are getting very close to understanding our path forward and our journey to carbon neutrality.”

LKAB plots carbon-free pathway with direct reduced iron switch

LKAB has presented its new strategy for the future, setting out a path to achieve net-zero carbon emissions from its own processes and products by 2045, while securing the company’s operations with expanded mining beyond 2060.

Jan Moström, President and CEO of LKAB, said the plan represented the biggest transformation in the company’s 130-year history, and could end up being the largest industrial investment ever made in Sweden.

“It creates unique opportunities to reduce the world’s carbon emissions and for Swedish industry to take the lead in a necessary global transformation,” he said.

The strategy sets out three main tracks for the transformation:

  • New world standard for mining;
  • Sponge iron (direct reduced iron) produced using green hydrogen will in time replace iron ore pellets, opening the way for a fossil-free iron and steel industry; and
  • Extract critical minerals from mine waste: using fossil-free technology to extract strategically important earth elements and phosphorous for mineral fertiliser from today’s mine waste.

The transformation is expected to require extensive investments in the order of SEK10-20 billion ($1.2-2.3 billion) a year over a period of around 15 to 20 years within LKAB’s operations alone. The company said the new strategy was a response to market developments in the global iron and steel industry, “which is undergoing a technology shift”.

The move could cut annual carbon dioxide emissions from the company’s customers worldwide by 35 Mt, equivalent to two thirds of Sweden’s domestic greenhouse gas emissions, it said.

Developments under the HYBRIT project, in which SSAB, LKAB and Vattenfall are collaborating on a process to enable the reduction of steel from iron ore using hydrogen instead of carbon, will be keenly observed following the miner’s announcement.

On top of this collaboration, LKAB is working with Sandvik, ABB, Combitec, Epiroc and several other industry leaders to develop the technology that will enable the transition to fossil-free, autonomous mines, it said.

Moström added: “The market for iron and steel will grow and, at the same time, the global economy is shifting towards a carbon-free future. Our carbon-free products will play an important part in the production of railways, wind farms, electric vehicles and industrial machinery.

“We will go from being part of the problem to being an important part of the solution.”

The market for steel is forecasted to grow by 50% by 2050. This growth will be achieved by an increase in the upgrading of recycled scrap in electric arc furnaces, according to LKAB. Today, the iron and steel industry accounts for more than a quarter of industrial emissions and for 7% of the world’s total carbon dioxide in the atmosphere, according to an IEA report.

The company said: “The global market price for recycled scrap is now twice that of iron ore pellets. The carbon-free sponge iron that will in time replace iron ore pellets as LKAB’s main export product is suitable for arc furnaces, allowing the company to offer industries throughout the world access to carbon-free iron.”

Moström said the switch from iron ore pellets to carbon-free sponge iron was an important step forward in the value chain, increasing the value of its products at the same time as giving customers direct access to “carbon-free iron”.

“That’s good for the climate and good for our business,” he said. “This transformation will provide us with good opportunities to more than double our turnover by 2045.”

During the transformation period, LKAB will supply iron ore pellets in parallel with developing carbon-free sponge iron.

To reach the new strategy’s goals, rapid solutions must be found for various complex issues, according to the company. These include permits, energy requirements and better conditions for research, development and innovation within primary industry.

Moström said: “Our transformation will dramatically improve Europe’s ability to achieve its climate goals. By reducing emissions primarily from our export business, we will achieve a reduction in global emissions that is equivalent to two-thirds of all Sweden’s carbon emissions. That’s three times greater than the effect of abandoning all cars in Sweden for good.

“It’s the biggest thing we in Sweden can do for the climate.”

Göran Persson, Chairman of the Board of LKAB, said: “What Swedish industry is now doing, spearheaded by LKAB, is to respond to the threatening climate crisis with innovation and technological change. In doing so, we are helping to secure a future for coming generations. This will also create new jobs in the county of Norrbotten, which will become a hub in a green industrial transformation. Succeeding in this will create ripples for generations to come. Not just here, but far beyond our borders.

“Now we are doing, what everyone says must be done.”

SSAB, LKAB and Vattenfall start up world’s first pilot plant for fossil-free steel

SSAB, LKAB and Vattenfall have celebrated the start-up of their HYBRIT pilot plant as part of a project to produce fossil-free sponge iron.

Sweden Prime Minister, Stefan Löfven, started up the plant together with Isabella Lövin, Minister for Environment and Climate and Deputy Prime Minister in Sweden, Martin Lindqvist, President and CEO of SSAB, Jan Moström, President and CEO of LKAB, and Magnus Hall, President and CEO of Vattenfall, today.

The achievement comes just over two years since ground was broken to mark the start of the pilot plant build for fossil-free sponge iron (direct reduced iron/hot briquetted iron) with financial support from the Swedish Energy Agency.

At the plant, HYBRIT will perform tests in several stages in the use of hydrogen in the direct reduction of iron ore. The hydrogen will be produced at the pilot plant by electrolysing water with fossil-free electricity. Tests will be carried out between 2020 and 2024, first using natural gas and then hydrogen to be able to compare production results.

The framework for HYBRIT also includes a full-scale effort to replace fossil oil with bio oil in one of LKAB’s existing pellet plants in Malmberget, Sweden, in a test period extending until 2021. Preparations are also under way to build a test hydrogen storage facility on LKAB’s land in Svartöberget in Luleå, near the pilot plant.

The HYBRIT initiative has the potential to reduce carbon dioxide emissions by 10% in Sweden and 7% in Finland, as well as contributing to cutting steel industry emissions in Europe and globally. Today, the steel industry generates 7% of total global carbon-dioxide emissions, according to the companies.

“With HYBRIT, SSAB, LKAB and Vattenfall aim to create a completely fossil-free value chain from the mine to finished steel and to introduce a completely new technology using fossil-free hydrogen instead of coal and coke to reduce the oxygen in iron ore,” they said. “This means the process will emit ordinary water instead of carbon dioxide.”

SSAB, LKAB and Vattenfall plot HYBRIT pilot production pathway

SSAB, LKAB and Vattenfall are taking another important step in their fossil-free steelmaking journey with preparations now underway for the construction of a demonstration plant on an industrial scale for its HYBRIT initiative.

The companies have also started consultations for deciding on placement of this demo plant in Norrbotten, Sweden.

The objective of the joint venture HYBRIT project is to develop the world’s first fossil-free, ore-based steelmaking process. The by-product of using fossil-free electricity and hydrogen in steelmaking, instead of coke and coal, will be water, instead of carbon dioxide. The partners believe the initiative has the potential to reduce Sweden’s total carbon dioxide emissions by 10%, hence the reason the Swedish Energy Agency has granted financial support for the project.

The plan is for construction of the demonstration plant to start in 2023, with the goal of taking the plant into operation in 2025.

“The intention is to be able to demonstrate full-scale production with a capacity of just over 1 Mt/y of iron per year, ie 20% of LKAB’s total processing capacity at Malmberget and almost half of the production capacity of SSAB’s blast furnace in Luleå,” the company said. “The goal is to be first in the world to produce fossil-free steel as early as 2026.”

HYBRIT is now starting an investigation into the selection of a location for the demonstration plant. Parallel consultations are being launched at two sites in Sweden: the Vitåfors industrial estate in Gällivare Municipality, where LKAB has mining operations, and the Svartön industrial estate in Luleå, where facilities including SSAB’s steel mill and LKAB’s ore port are located.

“The purpose is to consult and conduct an open dialogue about the location and design of the plant ahead of the upcoming selection of the site and permit application,” the companies said. “Consultation with government agencies, organisations and the public will begin in June and conclude in September 2020.”

The choice of location will have a major impact on future competitiveness and climate benefits, according to the partners, with investment decisions made once the authorisation procedure and other investigations have been completed.

HYBRIT’s pilot phase will run in parallel with the demonstration phase. In Luleå, the pilot plant for fossil-free steel will be fully constructed during the summer, and preparations are also under way to initiate construction of a temporary hydrogen store to test the technology for storing hydrogen in caverns, the partners said.

Martin Pei, Chief Technical Officer at SSAB and Chairman of HYBRIT, said: “We want to build the plant in Norrbotten. There’s good access to fossil-free electricity and competence here, as well as close collaboration with academia and the community. A demonstration plant for fossil-free iron production would also be positive for growth and jobs in the region, as well as contributing to a major climate benefit.”

Markus Petäjäniemi, Senior Vice President Market and Technology at LKAB, said HYBRIT is an important piece of the “jigsaw puzzle” in a green transition, in which we want to “climate-optimise” the whole chain from mine to finished steel by the year 2045.

“We want Norrbotten to be a world-leading arena for innovation and a centre of knowledge for the global mining and minerals sector,” he added.

HYBRIT hydrogen storage facility finds financial backing

SSAB, LKAB and Vattenfall have agreed to invest SEK150 million ($15.2 million) on construction of a storage facility for hydrogen at the HYBRIT pilot plant for fossil-free steel.

The funding, which comes on top of the Swedish Energy Agency’s close to SEK50 million pledge, is an important step towards the goal of fossil-free iron and steel production, the HYBRIT joint venture partners said.

The HYBRIT initiative began in 2016. By using fossil-free electricity and hydrogen instead of coke and coal in steel production, the emissions will be water instead of carbon dioxide. The initiative has the potential to reduce Sweden’s total carbon dioxide emissions by 10%, according to company estimates.

The plan is to build the new hydrogen gas storage facility 25-35 m below the ground surface on LKAB’s land in Svartöberget, Sweden, close to the pilot plant currently under construction on SSAB’s site in Luleå. Construction of the 100 cu.m storage facility is expected to start in 2021 and it will operate from 2022-2024. It is expected to be a pressurised hydrogen gas storage facility in a bedrock cavern with a steel lining as a sealing layer.

The implementation study for the HYBRIT initiative showed large-scale storage of hydrogen gas can play an important role in Sweden’s future energy system. As well as acting as a buffer to ensure an even flow to the steel production, a large-scale hydrogen gas storage facility would offer a better opportunity to balance the electricity system with a greater proportion of weather-dependent power generation, and enable a competitive production cost for the fossil-free steel, according to the project partners.

Magnus Hall, Vattenfall’s President and CEO, said: “I am very pleased that we, as partners, are step by step developing our joint fossil-free steel project, and the support from the Swedish Energy Agency is important.

“Now, with the support of the community, we are investing in the next piece of the jigsaw puzzle for a value chain in which hydrogen gas plays a decisive role in the success of the initiative and the development of competitive fossil-free electricity generation in Sweden.”

Martin Lindqvist, SSAB’s President and CEO, said the investment in a storage facility for fossil-free hydrogen gas is “an important building block in achieving our goal of a fossil-free value chain from ore to finished steel”, with Jan Moström, LKAB’s President and CEO, adding that he was pleased the project could make use of parts of the company’s former ore port facility for the experiment.

Robert Andrén, Director General of the Swedish Energy Agency, said large, complex and expensive leaps in technology need to be taken for the sake of the climate, to achieve the goal of zero net emissions.

“Large-scale storage of hydrogen gas will be an important piece of the jigsaw puzzle for a fossil-free value chain for steel manufacturing, but also in a future electricity system with an increasing proportion of weather-dependent power,” he said.

In June last year, SSAB, LKAB and Vattenfall, the HYBRIT initiative partners, started the construction of a unique pilot plant in Luleå. Work also began recently on the reconstruction of a pellet works in Malmberget to replace fossil fuel with bio oil, with the aim of manufacturing fossil-free pellets.

The pilot plants for fossil-free steel production will be used from 2021 to 2024, and the partners are already looking into the possibility of scaling up the manufacturing by building a demonstration plant in 2025, three years earlier than previously planned, to produce fossil-free steel from iron ore for commercial use. The aim for 2035 is to sell fossil-free steel on a broad scale.

HYBRIT partners to speed up fossil-free steelmaking plans

The partners of the HYBRIT project, LKAB, SSAB and Vatenfall, have said they could move up their plans to build a fossil-free steelmaking demonstration plant by three years, to 2025.

Writing in Swedish daily newspaper Dagens Nyheter, the Presidents and CEOs of the three companies, Martin Lindqvist (SSAB), Jan Moström (LKAB) and Magnus Hall (Vattenfall), said they were ready to step up their work for fossil-free steel production and to move up plans to reduce carbon dioxide emissions.

The aim of HYBRIT, which is supported by the Swedish Energy Agency, is to develop a process for fossil-free steelmaking by 2035.

In 2018, the Swedish Energy Agency announced it would contribute funding amounting to more than SEK500 million ($54 million) towards the pilot-scale development of an industrial process, with three owners, LKAB, SSAB and Vattenfall, each contributing a third of the outstanding capital for the project.

Back in April, the partners said construction of a biofuel-based pelletising plant would shortly begin at LKAB’s Malmberget site, in Sweden. This “world-unique test facility”, a key component of the HYBRIT initiative, will see fossil fuels replaced with biofuel to achieve fossil-free production of iron ore pellets.

In the opinion piece in Dagens Nyheter, the company heads said: “We are ready to increase efforts from our side, but if we are to achieve success, society and lawmakers must do the same.

“We are already looking into the possibility of building a demonstration plant in 2025, three years ahead of plan, so that we can immediately thereafter produce iron ore-based, fossil-free steel for commercial use.

“The goal is to be selling fossil-free produced steel on a broad scale by 2035,” they said.

The three companies highlighted four important preconditions for this rapid transition to succeed:

  • “We need large volumes of fossil-free electricity. According to our calculations, the transition to HYBRIT requires the equivalent of about 10% of Sweden’s current electricity consumption. There will also be demand for electricity from other companies and consumers. We will need continued good access to fossil-free electricity with a high level of delivery reliability, competitive pricing and initiatives to create greater flexibility, eg through opportunities to store energy. This work must not be delayed. We are prepared to assist in these efforts;
  • “The public sector in Sweden must get involved and share the risk. Investing in groundbreaking technology such as HYBRIT is often risky, time-consuming and associated with major investments. At the same time, the projects bring great social benefit in the form of increased research, competence and opportunities to achieve climate goals. The Swedish government’s proposal to double the Industrial Evolution initiative over three years is good, but it needs to be secured for a long time to come. A fund is also needed at the EU level, and there may also be a need for support in being able to write off and scrap old plants (so-called stranded assets) in favour of new, sustainable technology;
  • “As a society, we cannot afford to keep emitting greenhouse gases. The EU trading system for emission allowances is currently being revised, and as a result, the costs of carbon dioxide emissions are rising. The system should be designed from 2020 to benefit the most climate-efficient methods from quarrying in the rock to finished steel. The system needs to be developed even after the upcoming trading period. Sweden and the rest of the EU also need to strive to change other parts of the world ahead of similar systems. Bold, sustainable solutions must not be prevented because parts of the world have a lower level of ambition and therefore carry on using old technology; and
  • “Effective, appropriate permit testing in Sweden is required so that work on the transition is not significantly delayed or stopped completely, not least so that sufficient electricity can be obtained now that we have the opportunity to move up the demonstration phase. It can sometimes take 10 years to obtain an environmental permit or a concession to lay an electrical cable or to upgrade the grid. The Swedish government is planning some measures, but more work is needed.”

The three concluded: “Steel is an amazing material. It builds communities, is hard-wearing and can in principle be recycled an infinite number of times.

“But recycled steel will not be enough. In line with social development, population growth and increasingly higher standards of living all over the world, demand will increase for new steel made from iron ore. Therefore, sustainable solutions are needed; solutions that contribute not just to solving climate change, but to social development.”

HYBRIT fossil-free steelmaking project moves forward with biofuel plant build

A joint initiative between LKAB, SSAB and Vattenfall to develop the world’s first fossil-free steelmaking process is gaining momentum, with construction of a biofuel-based pelletising plant shortly beginning at the iron ore miner’s Malmberget site, in Sweden.

This “world-unique test facility”, a key component of the HYBRIT initiative, will see fossil fuels replaced with biofuel to achieve fossil-free production of iron ore pellets.

The aim of HYBRIT, which is supported by the Swedish Energy Agency, is to develop a process for fossil-free steelmaking by 2035.

In 2018, the Swedish Energy Agency announced it would contribute funding amounting to more than SEK500 million ($54 million) towards the pilot-scale development of an industrial process, with three owners, LKAB, SSAB and Vattenfall, each contributing a third of the outstanding capital for the project.

LKAB said: “Fossil-free steel production starts at the mine and LKAB is working hard to determine the design of the next generation of pelletising plants.”

Back in October, Tenova HYL was contracted by HYBRIT to supply its direct reduced iron solution as part of the project.

The biofuel-based plant, to be built near to LKAB’s Malmberget iron ore mine, will cost in the region of SEK80 million.

“Testing a bio-oil system is part of the pilot phase and the objective is to convert one of LKAB’s pelletising plants from fossil fuel to 100% renewable fuel,” the company said. “This means that fossil-generated carbon dioxide emissions from the Malmberget operation will be reduced by up to 40% during the test period, which corresponds to about 60,000 t/y. Eventually, LKAB hopes to achieve totally carbon-dioxide-free pellet production.”

Jan Moström, LKAB’s President and CEO, said: “Within HYBRIT, LKAB is examining options for replacing the heating technologies used in the pellet process, which are the heart of our processing plants. In parallel, trials will be conducted in an experimental facility in Luleå using an alternative heating technology. Trials will determine whether new biofuels and plasma burners will work in the unique setting of a pellet plant. Ultimately, this will make LKAB’s iron ore pellets completely carbon-dioxide-free.”

The global iron and steel industry is one of the industrial sectors whose processes emit the most carbon dioxide, according to LKAB. “A growing population, in combination with greater urbanisation, means that demand for steel will continue to grow until 2050. If the HYBRIT initiative succeeds, Sweden’s carbon dioxide emissions will decrease by 10%,” the company said.

Mårten Görnerup, CEO, Hybrit Development AB, said: “The initiative is decisive for Sweden’s ability to meet the targets set out in the Paris Agreement and nationally, and it is our contribution to battling climate change. Fossil-free production of iron ore pellets is an important step towards reaching these goals.”

Following a pre-study conducted in 2016–2017, the first sod was turned in 2018 for a pilot plant for hydrogen-based reduction of iron ore in Luleå, Sweden. This plant, expected to be completed in 2020, will be used to test processes downstream from the pelletising plant. The investment in a pilot-plant for bio-oil in Malmberget, which is an important milestone for HYBRIT and the development of fossil-free pellet production, is expected to be completed by 2020. The first tests will be conducted up to 2021.

Magnus Hall, President and CEO, Vattenfall, said: “Our partnership with SSAB and LKAB is playing a very important role in the electrification of the industry and the development of fossil-free hydrogen to enable a fossil-free life within a generation.”

Martin Lindqvist, CEO and President of SSAB, said the partners are on their way to a revolutionary technical advancement, “showing the world that it is possible to produce steel without producing carbon dioxide emissions”.

He added: “Work is proceeding according to schedule and I am confident that we will succeed. As a first step toward creating a fossil-free SSAB, we have decided to switch to an electric arc furnace in Oxelösund. This will entail decommissioning both blast furnaces in around 2025 and will reduce our CO2 emissions in Sweden by around 25%,” he said.

The primary goal of HYBRIT is to eliminate fossil-generated carbon dioxide emissions and thereby stop the net increase in carbon dioxide in the atmosphere. This will be done by converting to renewable fuel.

In the next step, LKAB’s vision is to fully eliminate carbon dioxide emissions from the pelletising plants. LKAB’s iron ore consists largely of magnetite and, even without the use of bio-oil, it already gives the company a big environmental head-start on competitors, according to the company.

Steel produced from 100% LKAB iron ore pellets results in carbon dioxide emissions that are 14% lower when compared to steel manufactured at an average European sinter-based steel mill. “One explanation is that it requires less energy to make pellets from magnetite than from the more commonly occurring hematite. The pellet process currently requires a lot of energy, while a very great amount of heat is released when magnetite is converted to hematite.”

HYBRIT Chooses Tenova DRI for fossil-free steel-making tech

Tenova HYL has been contracted by HYBRIT to supply its direct reduced iron (DRI) solution as part of the world’s first fossil-free steel-making technology in Sweden.

HYBRIT, a joint-venture project between SSAB, LKAB and Vattenfall, was established in 2016 with an aim to replace coking coal, traditionally needed for ore-based steel making, with hydrogen, a fossil-free steel-making technology. This would result in steel with virtually no carbon footprint, the company says.

The Tenova HYL DRI technology will be used at HYBRIT’s pilot plant in Luleå, Sweden, which is expected to begin operations in 2020.

“Thanks to the unique characteristics of its process and its specific expertise in direct reduction with high content of hydrogen, Tenova HYL perfectly fitted with HYBRIT project,” Tenova said.

The company added that the “manoeuvrability” of production of the DRI module was another contributing factor, adding flexibility in terms of operations.

Mårten Görnerup, CEO of Hybrit Development AB, said: “By using state-of-the-art production technology as a starting point, we will more quickly reach our goal of a fossil-free future.”

HYBRIT’s goal is to have a solution for fossil-free steel by 2035.
