Cummins is to begin building its new GW electrolyser factory in Castilla-La Mancha, in Spain.
Construction of the proton exchange membrane (PEM) electrolyser plant is anticipated to be completed at the end of 2023.
It will initially create approximately 150 high-skill jobs, with the potential to add another 200 jobs as production grows.
The more than 20,000 sq metre facility will house system assembly and testing and have the capacity to produce 500MW of electrolysers per year, scalable to more than 1GW per year.
In 2021 Cummins announced it had selected Spain as the site of a new PEM electrolyser plant and purchased land in the industrial area of Guadalajara earlier this year, where it is now preparing to begin construction.
“We’re excited to be a part of Guadalajara and put down our roots in Spain. The growing hydrogen economy here continues to be an attractive environment for Cummins to increase its global electrolyser manufacturing footprint,” said Amy Davis, Vice President and President of New Power at Cummins.
“With the support of the Spanish government and European Union, Spain’s hydrogen market has great potential.
“This facility will poise Cummins to help European customers transition their energy supply and meet ambitious sustainability goals. This plant is also another step toward achieving Cummins’ own carbon neutrality targets.”
The company also recently announced the expansion of PEM electrolyser manufacturing capacity at its Oevel, Belgium, factory to 1GW.
“Green” hydrogen – produced through water electrolysis using renewable electricity – is a key enabler to economy-wide decarbonisation.
