Linde today (May 1) announced it would invest $150m to build, own and operate an ASU at the site of H2 Green Steel’s Boden green steel plant in northern Sweden to supply oxygen, nitrogen and argon.
The ASU is expected to start up by 2026 and also supply gases to existing and new customers.
Currently under construction, the Boden steel plant will produce five million tonnes of steel per year by 2030, with a 95% reduction in carbon dioxide (CO2) emissions compared to traditional steelmaking.
H2 Green Steel will use green hydrogen produced onsite from a 700MW electrolyser installation in the direct reduce iron (DRI) process, which the company’s Senior Vice-President – Iron Making, Durgesh Gupta told H2 View was one of the “most promising solutions for steel industry decarbonisation.”

Maria Persson Gulda, Chief Technology Officer at H2 Green Steel, said air separation was an “important part” of the company’s work in constructing the Boden plant.
In a separate agreement, Linde Engineering was awarded an engineering and procurement contract for a pressure swing adsorption unit at the Boden plant to recover and purify hydrogen from the DRI furnace.
The industrial gas major said the installation would minimise the hydrogen losses and boost overall steel production efficiency.
