Topsoe announces plans for 1GW hydrogen electrolyser factory in US after being allocated $136m in tax credits
Danish firm will manufacture solid-oxide electrolysers that 'produce 30% more H2 per kWh than rival technologies when paired with waste heat'
Danish manufacturer Topsoe has announced plans to build a 1GW solid-oxide-electrolyser factory in the US after being allocated $135.9m in 48C investment tax credits by the Biden administration.

A final investment decision (FID) on the more-than-$400m “state of the art” project in Chesterfield County, Virginia, will depend on “an assessment of market conditions and developments”, the company says.
The Danish company had previously revealed plans for a new electrolyser factory in the US, but had merely stated that it would be at least 500MW in size, cost about $300m, and that no location had been decided.
Construction is currently under way on Topsoe’s first solid-oxide-electrolyser-cell (SOEC) gigafactory, in Herning, Denmark, which will start up with 500MW of capacity and eventually be expanded to 5GW.
“Topsoe’s SOEC electrolysis technology is a modular design that operates at significantly higher temperatures compared to other electrolyzer technologies — a tested and proven process that enables industrial-scale production of green hydrogen using renewable electricity,” the company explains.
“When coupled with waste heat from downstream production (from processes producing ammonia, methanol or steel production), Topsoe’s SOEC technology will produce up to 30% more hydrogen per total power input when compared to conventional electrolyzer technologies. It further allows for the lowest levelized hydrogen cost per megawatt volume, no matter the industry.”
