Nel opens Heroya electrolyser plant
Firm says models manufactured at the plant are still on track to produce green hydrogen at $1.5/kg by 2025
Electrolyser manufacturer Nel has opened the world’s largest alkaline electrolyser production plant at Heroya in Norway. Nel says the facility has a production capacity of 500MW/yr and that this could rise to 2GW/yr with further investment—20pc of the 10GW/yr capacity the firm hopes to reach by 2025. The company says its electrolysers are still on track to produce green hydrogen at $1.5/kg by that date, although capex must be reduced to a quarter of today’s level to achieve this. “Half of the savings we need to make will come from scale-up and increased efficiency in production. The rest will come from the economy of scale and from effective industrial partnerships,” says Nel CEO Jon Andre L
