German electrolyser maker Sunfire GmbH has received an order to supply a 100-MW pressurised alkaline electrolyser to an unnamed European refinery.

The contract includes 10 modules of the company’s electrolysis technology, each with a capacity of 10 MW, as well as the power supply units. Sunfire will also supervise the installation and commissioning of the system. The electrolyser is scheduled to start operations in early 2026.

Sunfire earlier this year launched serial electrolyser production in Solingen, Germany. It aims to achieve production capacity of up to 1 GW per year by 2024.

“Now we are ready to deliver on large scale projects,” stated Sunfire chief executive Nils Aldag. He highlighted that the 100-MW deal is Sunfire’s first commercial order from a leading refinery in Europe and added that refineries are a target sector for the company as they aim to decarbonise their operations through green hydrogen.
