Harjavalta

The P2X Solutions Harjavalta plant is Finland's first industrial-scale renewable hydrogen and synthetic methane production facility, developed and operated by Finnish Power-to-X company P2X Solutions in the Harjavalta Industrial Park area in Western Finland. The plant was inaugurated on March 26, 2025. The facility integrates a 20 MW pressurized alkaline electrolyzer supplied by Germany's Sunfire GmbH, producing green hydrogen from renewable electricity at approximately 4,000 Nm³/h (roughly 400 kg/h) at full capacity, with a methanation unit supplied by Finland's Q Power Oy that upgrades a portion of the hydrogen (up to approximately 30%) into renewable synthetic methane (e-methane) by combining it with captured CO₂. Nameplate output is approximately 2,800 tonnes per year of hydrogen, 1,650 tonnes per year of synthetic methane, and 22,000 tonnes per year of oxygen at normal operation, with approximately 10 MW of waste heat recovered via heat pumps and transferred to the local district heating network. Renewable electricity is supplied by Fortum under a five-year Power Purchase Agreement running through 2029 that satisfies EU RFNBO (Renewable Fuels of Non-Biological Origin) monthly matching requirements. CO₂ feedstock for methanation is planned to be sourced primarily from a biogas production plant located approximately 2 kilometres from the site via a dedicated pipeline, with an industrial heat plant in the Harjavalta area as an alternative source. In November 2025 the plant was awarded Finland's first ISCC EU RFNBO certification, confirming compliance with EU renewable hydrogen sustainability requirements. Total project investment was approximately €70 million, supported by grants from the Finnish Ministry of Employment and the Economy, a capital loan from the Climate Fund, and equity and shareholder loan investments from Prime Capital AG.
