Linde to build $150m ASU for world’s first large-scale green steel plant


Linde revealed today that it will invest $150m into an on-site air separation unit (ASU) in Boden, northern Sweden, to supply industrial gases to the world’s first large-scale green steel production plant.

The ASU will generate oxygen, nitrogen and argon for H2 Green Steel’s integrated plant, which will use the latest technology to reduce carbon emissions by up to 95% compared to traditional steelmaking.

The industry is so carbon-intensive mainly due to the blast furnace process, which involves smelting iron ore with coal-derive coke at high temperatures, releasing CO2 emissions.

“We are moving at full speed on the journey to accelerate the decarbonisation of the steel industry through the construction of our plant in Boden,” said Maria Persson Gulda, CTO at H2 Green Steel.
