SSAB to supply fossil-free steel for construction equipment
SSAB says it has entered into an agreement with global construction equipment manufacturer Putzmeister to supply future fossil-free steel for use in manufacturing products such as concrete pump trucks and concrete mixers.
SSAB and Putzmeister have a long history of partnership and technical cooperation, Kallanish understands. By using SSAB’s Strenx high-strength structural steel and Hardox wear plates, Putzmeister has developed very strong and lightweight truck chassis, pump crane booms and concrete mixer drums. The lighter machines increase machine performance but also reduce carbon footprint, SSAB says.
This agreement replaces conventional steel with steel made via Hybrit technology, developed by SSAB with mining company LKAB and energy company Vattenfall, using green hydrogen and fossil-free electricity.

Hybrit green hydrogen-for-steel project completes storage test
Swedish renewable hydrogen-for-steel project Hybrit has completed a hydrogen storage pilot project, with flexible power procurement reducing variable operating costs by up to 31%, the group said Feb. 27.
The Hybrit collaboration between steelmaker SSAB, iron ore miner LKAB and power company Vattenfall said hydrogen production costs could be cut by 25%-40% when the first commercial plants are commissioned.
“The results show that it is technically possible to store fossil-free hydrogen gas for producing fossil-free iron and steel on an industrial scale,” Vattenfall said in a statement.
Hybrit optimized hydrogen storage in real time against both spot and intraday power markets, with cost savings of 26%-31% in the trial.
The pilot storage facility has operated intermittently since 2022 in 3-6-week periods.
“The pilot project has been highly successful and has given us the results we hoped for,” Vattenfall Industrial Partnerships industry decarbonization director Mikael Nordlander said in the statement. “We have shown that it is possible to use this technology to increase the flexibility of the electricity system and that it is a safe design that lasts over time.”
Vattenfall said the group reached 3,800 hours of operation, with 94% availability.
The project involved a 100-cu m steel-lined rock cavern in Svartoberget next to the direct reduction pilot plant for sponge iron production in Lulea, Sweden.
Hybrit said accelerated mechanical tests gave the equivalent results of 50 years’ operation.
The group will extend the pilot storage project to 2026 to carry out additional tests to optimize commercial storage design.
Vattenfall said around 7% of global CO2 emissions come from the steel sector. Hybrit technology could enable SSAB to reduce Sweden’s emissions by 10%, and Finland’s by 7%, it said.
Platts, part of S&P Global Commodity Insights, assessed carbon-accounted hot-rolled coil steel in Northwest Europe at $648/st on Feb. 26, compared with conventional HRC prices CFR Antwerp at Eur550/st ($576/st).
SSAB secures environmental permit for Lulea steelworks transformation
Nordic steelmaker SSAB received the necessary permit from the Land and Environmental Court in Umea, northern Sweden’s Vasterbotten County, to build and operate a mini-mill in Lulea, Norrbotten County, to replace the current blast furnace-based steel plant, it said in a Dec. 19 statement.
It said the permit enables a technology shift that would have positive effects on the environment and the climate and allow SSAB to meet the high demand for its steel products.
It further said construction preparations would now continue with detailed engineering and the building permit process. It added that once the new plant with electric arc furnaces, rolling mills, and further processing was running at full capacity, SSAB would decommission Lulea’s current blast furnace-based production system.
“This is a big day for SSAB and for the transformation to fossil-free steel production in Sweden. Now we can proceed with an investment that will result in reduced climate impact of national significance,” SSAB president and CEO Johnny Sjostrom said.
He added that the mill’s transformation would also create a more flexible and cost-effective production with a wider range of premium and special steel products with close to zero emissions and safeguard jobs in Lulea.
SSAB said the investment would result in a better cost position, higher efficiency, shorter lead times, and elimination of CO2 costs. The new mill would run on fossil-free electricity and be supplied with a mix of fossil-free sponge iron produced with its HYBRIT technology and recycled steel scrap.
Unlike traditional steelmaking, which relies on coking coal, SSAB’s HYBRIT process uses hydrogen, produced with renewable electricity, to produce sponge iron, which is then processed into steel. According to SSAB, the process emits water vapor instead of CO2 and largely eliminates CO2 emissions from the steelmaking process.
SSAB said the Lulea mill’s transformation would significantly reduce emissions to air and water, increase resource efficiency, and remove about 2.8 million mt/year of carbon dioxide emissions.
In total, SSAB’s transformation will enable a reduction of 10% in Sweden’s total CO2 emissions, of which 7% comes from Lulea and 3% from the transformation in Oxelosund, according to SSAB.
Platts, part of S&P Global Commodity Insights, assessed the daily Northwest Europe HRC carbon-accounted steel price at Eur615/mt ex-works Ruhr on Dec. 18, down 22% since the start of 2024.
Hybrit initiative presents final report
Sweden’s Hybrit initiative will present the results of six years of research into fossil-free direct reduced iron-making technology in a final report to the Swedish Energy Agency, Kallanish learns from SSAB, a partner in the project.
Hybrit is a collaboration between SSAB, mining company LKAB and energy company Vattenfall, which have received several patents based on the results. The project is now continuing in the next phase where the process is to be implemented on an industrial scale.
The pilot phase resulted in the development of a new hydrogen-based technology for efficient fossil-free iron and steel production with 0.0 tonnes of CO2 emissions per tonne of steel. It also developed a new fossil-free iron product – sponge iron – that has significantly better properties than iron reduced with fossil gases such as natural gas. It also produced an efficient process practice for melting fossil-free sponge iron into crude steel in an electric arc furnace.
The project is the first in the world to demonstrate that the fossil-free value chain – from iron ore to steel – works on a semi-industrial scale. So far, more than 5,000 tonnes of hydrogen-reduced iron have been produced at the pilot plant in Luleå. Customers such as Volvo, Epiroc, Peab and many more are already using the fossil-free steel in vehicles, heavy machinery, buildings and consumer products.
