The company has said it is currently installing the electrolysis modules, that are set to provide green hydrogen to produce sustainable aviation fuel (SAF), renewable diesel, and sustainable feedstock for plastics as part of the MultiPLHY project.

Under the EU-funded demonstration project, a 2.6MW high-temperature electrolyser, made up of twelve of Sunfire’s electrolysis modules, are set to be installed, contributing to Neste’s ambitions of reaching carbon neutral production by 2035.

H2 View understands the electrolyser is expected to be commissioned in early 2023 and will have capacity to produce more than 60kg of green hydrogen per hour, according to the company.

Christian von Olshausen, Chief Technical Officer at Sunfire, commented, “We are excited to commission our SOEC electrolyser on multi-megawatt scale soon. We have tested the solid oxide electrolysis cell (SOEC) modules intensively to make sure they meet the highest quality standards. Now it is time to demonstrate our technology in an industrial setting.”

Sunfire claim its SOEC technology operates at 850oC. By using industrial off-heat, the electrolyser processes water steam, reducing electricity demand.

The MultiPLHY consortium involving Neste, Sunfire, CEA, Paul Wurth and ENGIE, seeks to produce 960 tonnes of renewable hydrogen by the end of 2024 in Rotterdam, coming as part of the EU Horizon FCH2-JU programme.

Nils Aldag, CEO of Sunfire, said, “Net Zero cannot be reached alone, that’s why we need pioneering partners to turn out vision of a world free from fossil fuels into reality.

“Our innovative electrolysers help refineries like Neste to accelerate the green transition. MultiPLHY demonstrates that we are ready to deliver and implement our electrolysers in the multi-megawatt range.”
