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 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.”

Tenova HYL to supply direct reduction iron technology to Sinosteel in Bolivia

Tenova says its HYL division will supply a DRI Micro-Module to steelmaker Sinosteel for its Empresa Siderúrgica del Mutún (ESM) project in Bolivia.

Tenova HYL’s direct reduction technology will be used for the first stage of the project, which will include a 250,000 t/y direct reduction iron (DRI) facility, a 650,000 t/y concentration plant, a 400,000 t/y pelletising facility for Mina El Mutún and a steel plant with a continuous caster and rolling mill with a total capacity of 190,000 t/y of long steel products.

“This cost-effective Micro Module will use the state-of-the-art ENERGIRON Zero-Reformer (ZR) Process and will be capable of supplying the melt shop with high quality DRI with metallisation levels of 94% and an adjustable high carbon content in the range of 3% to 4%,” the company said.

Rubén Rodríguez, Sales Manager at Tenova HYL, said the contract was very significant, with construction of these facilities being the “cornerstone in what surely is the beginning of the steelmaking industry in Bolivia”.

Stefano Maggiolino, President and CEO at Tenova HYL, said: “After the recent successful projects in Asia, Africa, Europe and North America, we are glad that the first DR plant built in South America in the last 20 years will use the state-of-the-art ENERGIRON technology.”

The 250,000 t/y Micro Module plant is expected to be in operation in mid-2021.
