Cummins To Build Electrolyzer Plant In Spain

The plant will have an initial production capacity of 500 MW/year and is scalable to more than 1 GW/year.

Cummins has unveiled plans to build a plant in Spain to make electrolyzer systems that will be used to produce green hydrogen. The Columbus, Indiana, based engine manufacturer will spend US$60 million to build a 236,806-sq.ft. (22,000-m2) facility that will produce the world’s largest electrolyzer systems, with an initial production capacity of 500 MW/year that will be scalable to more than 1 GW/year. A site selection search is underway within Castilla-La Mancha, Spain, with the facility expected to open in 2023.


Cummins has partnered with Spanish utility provider Iberdrola on the plant. The companies have signed an agreement to accelerate the growth of business opportunities in the electrolyzer market, promoting the green hydrogen value chain and making Spain a leader of this technology and industry. This alliance helps to position Cummins as a supplier of electrolyzer systems for large-scale projects in Spain and Iberdrola as a leading developer of electrolyzer projects and hydrogen supplier to final industrial customers.


This investment in Spain comes on the heels of Iberdrola and Cummins’ decision to partner together on large-scale hydrogen production projects in Spain and Portugal.


“Spain offers a strong and dynamic local environment for hydrogen production, and we are excited to invest here and significantly increase our manufacturing capacity in Europe,” said Tom Linebarger, Chair and CEO of Cummins. “Our partnership with Iberdrola will connect us with a major clean energy company and strategically positions us to be a European leader in green hydrogen production. We believe that this is just the start of our expansion into new markets, bringing new clean technology to customers, and supporting efforts to bring the European Union’s Green Deal to fruition. As communities move toward zero emissions, this is the latest example of Cummins’ global effort to achieve carbon neutrality and accelerate the hydrogen economy.”
