Kobe Steel says it has successfully demonstrated technology that can significantly reduce CO2 emissions from blast furnace operations, combining the technologies of Midrex in the engineering business and the blast furnace operation technology in the iron and steel business.

This achievement is a result of the integrated efforts of the Kobe Steel Group (also known as the KOBELCO Group) leveraging its diverse businesses, it said. The demonstration test was conducted for a month at a large blast furnace (4,844 cu.m) of the Kakogawa Works in Hyogo Prefecture, Japan, in October 2020.

The quantity of CO2 emissions from the blast furnace is determined by the reducing agent rate (RAR), or the quantity of carbon fuel used in blast furnace ironmaking. In the demonstration test, it was verified that RAR could be stably reduced from 518 kg per tonne of hot metal (thm) to 415 kg/thm by charging a large amount of hot briquetted iron produced by the MIDREX® Process. The results indicate that this technology can reduce CO2 emissions by approximately 20% compared with the conventional method, the company said.

In addition, the world’s lowest level of coke rate (239 kg/thm) has been achieved in the demonstration test of this technology, the company claimed.

Kobe Steel sees this as a promising solution that could become readily available soon at a lower additional cost compared with other CO2-reduction measures.

The MIDREX Process uses natural gas as the reductant and pellets made of iron ore as the source of iron to make direct reduced iron through the reduction process in the shaft furnace. In comparison with the blast furnace method, the MIDREX Process can reduce CO2 emissions by 20-40%.

The company said: “We will keep improving this CO2-reduction solution technology while further reducing CO2 emissions and achieving lower costs for CO2 reduction. Beyond our own efforts to reduce emissions from our facilities, we will strive to contribute to the acceleration of CO2 reduction through introducing this solution to blast furnaces around the world.

“In addition, we believe that the success of the demonstration test on an actual blast furnace has made a significant step forward in providing low CO2 steel products to customers. As moving forward with our environmental efforts on the scale of the whole supply chain, we will establish production and sales systems and define the terms and conditions for sales so that we can provide customers with low CO2 steel products that offer new added value.”

BHP, JFE Steel to scrutinise Australian steel raw materials emissions in latest study

BHP has signed a memorandum of understanding (MoU) with leading Japanese steel producer, JFE Steel, to jointly study technologies and pathways capable of making material reductions to greenhouse gas emissions from the integrated steelmaking process.

BHP is prepared to invest up to $15 million over the five-year partnership, which, it says, builds on the strong history of technical research and collaboration between the two companies.

The company’s investment will be funded under its $400 million Climate Investment Program, set up in 2019 to coordinate and prioritise projects, partnerships, R&D and venture investments to reduce Scope 1, 2 and 3 emissions, invest in offsets and support development of technologies with the highest potential to impact change.

The JFE-BHP partnership will focus on the role of Australian raw materials to help to increase efficiency and reduce emissions from the blast furnace and direct reduced iron (DRI) steelmaking routes, it said. The partnership intends to study the properties of raw materials, with focus on specific areas such as iron ore pre-treatment, use of enhanced iron ore lump, high quality coke and DRI, required to decrease iron and steelmaking emissions and support a transition to a low carbon future. Throughout the collaboration, the two companies will also share knowledge on reducing carbon emissions across the steel value chain.

This JFE-BHP partnership follows other BHP investments to support the reduction of value chain emissions, including up to $35 million for the collaboration with China’s largest steelmaker, China Baowu, and awarding BHP’s first LNG-fuelled Newcastlemax bulk carriers contract, with the aim to reduce CO2-e emissions by 30% per voyage.

BHP’s Chief Commercial Officer, Vandita Pant, said: “This partnership with JFE demonstrates a joint commitment to make our activities more sustainable through collaboration and technological improvement. This work will support and help progress Japan’s carbon neutral ambitions by 2050.”

As outlined in BHP’s decarbonisation framework, the steel industry is expected to move through stages of optimisation and transition for the existing integrated steelmaking route before reaching an end state of low or no carbon intensity.

“Our investments are focused on actions that can create real change, and we continue to take positive steps on our climate agenda and in collaborating with others to help reduce emissions in line with the Paris Agreement goals,” Pant said.

JFE’s President and Chief Executive Officer, Yoshihisa Kitano, said: “We understand that raw material processing technology is extremely important in the research and development towards carbon neutrality. We have a long history working closely together with BHP collaborating to study raw material utilisation technology and mine development. It is very significant for us to be able to work together with BHP towards reduction of CO2 emissions, which is an extremely important agenda for the steel making sector.”

BHP and China Baowu take on steel industry GHG emission reduction challenge

BHP has signed a memorandum of understanding (MoU) with leading steel producer, China Baowu, with the intention, it says, to invest up to $35 million and share technical knowledge to help address the challenge of reducing greenhouse gas emissions facing the global steel industry.

The five-year partnership will focus on the development of low carbon technologies and pathways capable of emission intensity reduction in integrated steelmaking, according to BHP. Under the MoU, the deployment of carbon capture, utilisation and storage in the steel sector will also be investigated at one of China Baowu’s production bases.

BHP’s investment will be funded under the $400 million Climate Investment Program, set up last year to coordinate and prioritise projects, partnerships, R&D and venture investments to reduce Scope 1, 2 and 3 emissions, offsets and support development of technologies with the highest potential to impact change.

BHP Chief Executive Officer, Mike Henry (pictured left), said the companies would collaborate on technical solutions to use low carbon fuel sources such as hydrogen injection in the blast furnace, and explore other low emission options in support of China Baowu and the steel industry’s low carbon transformation and green development goals.

“This MoU further strengthens our longstanding relationship with China Baowu and reflects our joint determination and commitment to help reduce emissions in line with the Paris Agreement goals,” Henry said.

“BHP will invest in supporting the development of low emissions technologies, promote product stewardship and partner with others to enhance the global policy and market response to climate change. Our investments are focused on actions that can create real change in emissions.”

In September, BHP awarded a tender for world’s first LNG-fuelled Newcastlemax bulk carrier to carry iron ore between Western Australia and China, which will reduce emissions by more than 30% per voyage.

In October 2019, China Baowu, meanwhile, announced the establishment of a Low Carbon Metallurgy Innovation Centre and plans to establish a Global Low Carbon Metallurgy Innovation Alliance.

China Baowu Chairman, Chen Derong, said the MoU with BHP will further enhance and broaden the existing strategic partnership between the companies, and establish a model of joint industrial efforts to promote technological innovation and a sustainable transition to a lower carbon world.

“At the UN General Assembly, President Xi Jinping delivered an important speech that outlined China’s low carbon transformation and development,” Chen Derong said. “Low carbon transition and green development represent a major disruption to the traditional steelmaking value chain.

“As a leading company in the sector, China Baowu will take an active role in implementing low carbon technologies, working together with upstream and downstream partners.

“The global steel industry needs an open platform to jointly explore low carbon technology and roadmaps, as well as showcase to the world the efforts to reshape the steelmaking value chain.”

Consistent with the ambitions of China Baowu and BHP to drive efficiency and address emissions across the global steel industry, both companies will work together to establish a China Baowu-BHP Low Carbon Metallurgy Knowledge Sharing Center, to link complementary research and share low carbon and green development knowledge with domestic and international steel industry stakeholders, the two companies said.

BHP weighs trolley assist and IPCC as part of decarbonisation efforts

BHP has provided an update on its progress on climate action, new climate commitments and how it integrates climate change into corporate strategy and portfolio decisions in a new report.

The company’s climate change approach focuses on reducing operational greenhouse gas emissions, investing in low emissions technologies, promoting product stewardship, managing climate-related risk and opportunity, and partnering with others to enhance the global policy and market response, it says.

“BHP supports the aim of the Paris Agreement to limit global warming to well below 2°C above pre-industrial levels, and pursue efforts to limit warming to 1.5°C,” the company clarified.

It explained: “BHP has been active in addressing climate risks for more than two decades, and has already established its long-term goal of achieving net zero operational (Scope 1 and 2) emissions by 2050 and its short-term target of maintaining operational emissions at or below financial year (FY) 2017 levels by FY2022, using carbon offsets as required.”

In the past year, BHP has made progress on this aim, announcing that the Escondida and Spence copper mines in Chile will move to 100% renewable energy by the mid-2020s, and, last week, awarding new renewable energy contracts for its Queensland coal assets, and the world’s first LNG-fuelled Newcastlemax bulk carrier tender.

BHP’s climate change briefing and 2020 climate change report outline how the company will accelerate its own actions and help others to do the same, it said. Today’s update sets out:

  • A medium-term target to reduce operational greenhouse gas emissions by at least 30% from adjusted FY2020 levels by FY2030;
  • Scope 3 actions to contribute to decarbonisation in its value chain. This includes supporting the steelmaking industry to develop technologies and pathways capable of 30% emissions intensity reduction with widespread adoption expected post-2030 and, in terms of transportation, supporting emissions intensity reduction of 40% in BHP-chartered shipping of products;
  • Strengthened linking of executive remuneration to delivery of BHP’s climate plan; and
  • Insight into the performance of BHP’s portfolio in a transition to a 1.5°C scenario.

The report also outlined some examples of emission reduction projects the miner is considering, which will be weighed as part of the maintenance capital category of its capital allocation framework. This includes solar power installations; alternative material movement technologies such as overland conveyors and in-pit crush and convey solutions; and trolley assist to displace diesel for haul trucks.

The company expanded on this in its report: “The path to electrification of mining equipment will likely include solutions such as trolley assist, in-pit crush and convey, overland conveyors and battery solutions.

“Diesel displacement represents a higher risk, higher capital step towards decarbonisation, so a phased approach to execution is proposed with particular emphasis on Minerals Americas-operated assets that are further advanced on the decarbonisation journey. Taking a transitional approach to electrification provides flexibility to allow for the potential for rapid development of emerging technologies and to resolve the complexities of integrating these technologies into existing operations.

“During FY2021, we will seek to collaborate further with International Council on Mining and Metals members, industry and original equipment manufacturers to progress research and development to reduce costs and assess any potential impacts from electrified mining equipment solutions to replace current diesel options.”

BHP Chief Executive Officer, Mike Henry, said of the report: “I’m pleased today to show how we are accelerating our own actions and helping others to do the same in addressing climate change. We see ourselves as accountable to take action. We recognise that our investors, our people and the communities and nations who host our operations or buy our products have increasing expectations of us – and are responsive to these.

“Our approach to climate change is defined by a number of key requirements. Our actions must be of substance. They must be real, tangible actions to drive emissions down. We must focus on what we can control inside our business, and work with others to help them reduce emissions from the things that they control. To create long-term value and returns over generations, we must continue to generate value and returns within the strong portfolio we have today, while shaping our portfolio over time to benefit from the megatrends playing out in the world including decarbonisation and electrification.

“Our portfolio is well positioned to support the transition to a lower carbon world aligned with the Paris Agreement. Our commodities are essential for global economic growth and the world’s ability to transition to and thrive in a low carbon future. Climate change action makes good economic sense for BHP and enables us to create further value.”

GFG Alliance to take over TEMCO manganese alloy smelter following South32 pact

South32’s association with the Tasmanian Electro Metallurgical Company (TEMCO) is set to come to an end after it agreed to sell its stake in the manganese alloy smelter to an entity within the GFG Alliance.

The announcement from South32’s Groote Eylandt Mining Company (GEMCO) said completion of the transaction was subject to approval from Australia’s Foreign Investment Review Board. Upon satisfaction of this condition, GFG will make a nominal payment to GEMCO to acquire 100% of the shares in TEMCO, it said, without naming an acquisition price.

As a condition to the completion of the transaction, the parties have entered into an ore supply agreement from GEMCO to TEMCO.

The smelter, in Tasmania, Australia, is run by the Samancor Manganese joint venture, owned 60% by South32 and 40% by Anglo American.

South32 says TEMCO uses ore shipped from its GEMCO operations in the Northern Territory of Australia and produces ferromanganese for steelmaking. Most of the alloy produced is exported to customers in Asia and North America, with the remaining sold to steel producers in Australia and New Zealand.

South32 CEO Graham Kerr said the agreement represented another milestone for South32 as it continues to reshape its portfolio.

“Today’s agreement follows an extensive review of options regarding the future of our manganese alloy business,” he said.

“The transaction and our ongoing supply of ore to TEMCO will see the smelter, first established in 1962, continue to operate into the future.

“Looking forward, we are confident that GFG, a current TEMCO customer, is well placed to operate the smelter, with the acquisition representing an opportunity to further vertically integrate its steel business.”

The transaction does not include the Samancor Manganese JV’s South African manganese alloy smelter, Metalloys, which has separately been placed under care and maintenance, South32 added.

thyssenkrupp looks to go ‘climate neutral’ by 2050

thyssenkrupp has set some ambitious greenhouse gas emission goals as it looks to fall in line with the 2015 Paris Climate Agreement.

The group aims to cut 30% of its emissions from production and outsourced energy by 2030, and become “climate neutral” by 2050, it said.

thyssenkrupp CEO, Guido Kerkhoff, said: “The threats posed by climate change affect us all. As an industrial company with operations around the globe, we are in a particularly good position to reduce greenhouse gas emissions through sustainable products and processes. We take this responsibility very seriously and have received several awards for this in recent years. Now, we are setting ourselves clear targets for 2030 and 2050 as the next logical step.”

In February, thyssenkrupp was named as a global leader in climate protection for the third year in a row by the non-governmental organisation, CDP, which assesses whether companies have formulated a coherent strategy on how to further improve their own environmental performance as well as that of customers and suppliers. The company, once again, achieved the highest score possible and was placed on CDP’s global ‘A List’, it said.

The targets now announced take in thyssenkrupp’s own production operations, the energy it purchases and its products. In steel production, for example, thyssenkrupp is currently pursuing two approaches to reducing CO2 emissions: The Carbon2Chem project, which is expected to be available on an industrial scale before 2030, and the so-called hydrogen route, which should take full effect by 2050 and make the biggest contribution to directly avoiding CO2. Carbon2Chem converts steel mill emission gases, including the CO2 they contain, into valuable chemicals.

thyssenkrupp’s hydrogen route, meanwhile, involves replacing coal with ‘green’ hydrogen as the reducing agent for blast furnaces so that, in the long term, no CO2 is created in the production of steel. These technologies are being funded by the German federal government and the state of North Rhine-Westphalia.

Under its Climate Action Program for Sustainable Solutions, thyssenkrupp will also systematically work to make its products carbon neutral. The group already offers a technology for the cement industry that permits CO2 emissions from the combustion processes to be captured for subsequent storage or processing. In the area of sustainable mobility, thyssenkrupp is working with European partners to produce fuel from biomass. These fuels reduce CO2 emissions by up to 90% compared with conventional fuels, according to thyssenkrupp.

Other key areas include the e-mobility sector, where thyssenkrupp supplies battery production lines and special steels for electric motors. The group is also actively involved in the development of energy storage solutions, for example with electrolysis systems that convert electricity into hydrogen. These storage systems allow a constant supply of electricity from renewables regardless of the weather, thyssenkrupp says.

Dr Donatus Kaufmann, thyssenkrupp Board member responsible for technology, innovation, sustainability, legal and compliance, said: “Our goals are ambitious but achievable. Our strategy for our steel operations alone will cut production-related emissions there by 80% by 2050. But if we are to achieve our climate targets, we need to make significantly more use of renewable energies. Also, there are no internationally harmonised financial incentives for investments in CO2 abatement technologies. These are basic requirements for making a real change.”

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.”
