Sunfire installs 20-MW electrolysis plant in Finland

German electrolyser manufacturer Sunfire says it has installed Finland’s first industrial-scale electrolysis plant in Harjavalta, with green hydrogen production anticipated to start later this year.

The 20-megawatt pressurised alkaline electrolyser is installed at Finnish green hydrogen developer P2X Solution’s hydrogen plant in western Finland. The project started construction a year ago. At full capacity, the plant will produce 400 kilograms/hour of green hydrogen using wind energy. It will be commissioned in the coming months, according to Sunfire.

The project also has a methanisation plant, which will produce “renewable synthetic methane” from carbon dioxide and green hydrogen, Kallanish learns from a statement.

P2X signed an offtake agreement with Danisco Sweeteners, a unit of US-based International Flavors & Fragrances, for green hydrogen produced from the plant last November. The company will use the green hydrogen at its plant in Kotka, Finland, to reduce carbon emissions during the production of xylitol, a synthesised sugar alternative used in the food industry.

P2X is targeting a total capacity of 1 gigawatt for green hydrogen production by 2031.

“Green hydrogen will play a crucial role in the transformation of the chemical sector,” says Sunfire ceo, Nils Aldag. “We feel privileged to be part of this pioneering project with P2X Solutions, where our pressurised alkaline electrolyser will be operated on an industrial scale. I am especially pleased that our ‘Made in Europe’ electrolysis technology will contribute to Finnish energy history.”

The project has an estimated total investment of €70 million ($75.4m). Of this, €36m was provided by the Finnish government’s Ministry of Economic Affairs and Employment and the Finnish Climate Fund.

Based in Dresden, Germany, Sunfire develops and manufactures electrolysers based on solid oxide electrolyser cell (SOEC) and alkaline technologies. Last September, German energy developer RWE produced the first green hydrogen at its gas-fired power plant in Emsland, Germany, using a 250-kilowatt (kW) SOEC supplied by Sunfire.

Early last year, the company also began the series production of alkaline electrolysers at its Solingen site in Germany.

Andritz to supply 100-MW electrolysis plant for Salzgitter green steel in Germany

Germany’s Salzgitter has ordered a 100-MW electrolysis plant from Andritz to produce green hydrogen, replacing coal in the steel production process at the company’s Salzgitter Flachstahl from 2026, the companies said in statements Sept. 20.

The plant will produce around 9,000 mt/year of hydrogen, with HydrogenPro supplying the high-pressure alkaline electrolyzers, using its 5.5-MW cell stacks, it said in a separate statement.

“This order represents a major milestone for our partnership with ANDRITZ, and the first step in our European expansion,” HydrogenPro CEO Jarle Dragvik said in the statement.

The project is part of Salzgitter’s Salcos program, which it will develop in three stages.

In a first phase from 2026, Salzgitter will commission a direct reduction plant, an electric arc furnace, and the 100-MW electrolysis plant.

The DRI unit will have a production capacity of over 2 million mt/year of direct reduced iron, while the EAF will produce 1.9 million mt/year of steel, according to Salzgitter Flachstahl and engineering company Primetal, which will build the EAF.

It aims to convert its operations to “virtually CO2-free steel production” by the end of 2033.

The first stage of Salcos is backed by subsidies from Germany’s federal government and the state of Lower Saxony, as well as by the company’s own funds.

Salzgitter Flachstahl Chairman Ulrich Grethe said the development of hydrogen infrastructure in Germany was key to unlocking industrial decarbonization.

“In order to enable us to reduce the CO2 footprint of our steel production in the future, it is imperative that we connect to the emerging hydrogen infrastructure as quickly as possible,” Grethe said in the statement.

German gas transmission system operators in July published a draft hydrogen pipeline network map, linking hydrogen production and demand centers, storage facilities, power plants and import corridors across the country.

The proposed network is made up of converted existing natural gas pipelines, along with newly constructed dedicated hydrogen pipes.

The core network will include key infrastructure expected to be operational by 2032, with scope to expand the network further in later stages.

Germany is targeting domestic renewable hydrogen production capacity of 10 GW by 2030, and is also eyeing large-scale imports through schemes such as H2Global.

Platts, part of S&P Global Commodity Insights, assessed the cost of producing renewable hydrogen via alkaline electrolysis in Europe at Eur6.15/kg ($6.58/kg) Sept. 19 (Netherlands, including capex), based on month-ahead power prices. Proton exchange membrane electrolysis production was assessed at Eur7.23/kg.
