Cummins opens one of world’s largest electrolyser plants in Spain

Its implementation has involved an investment of 50 million euros and has generated 150 jobs.
Accelera by Cummins, the zero-emissions segment of the US multinational energy solutions company Cummins, has officially inaugurated its first Spanish electrolyser manufacturing plant, located in Guadalajara.
The new facility will produce the main proton exchange membrane (PEM) electrolyser systems designed by Cummins. In its first phase, the plant has the capacity to produce 500 megawatts per year, and in later phases it will be able to increase this to one gigawatt. According to the company, this is one of the largest electrolyser production plants in the world.
Job creation
The start-up of the new 24,000-square-metre factory has created around 150 highly skilled jobs, which could rise to 200 when production grows. The electrolysers will be used to produce green hydrogen. The way the electrolysers themselves are manufactured is also sustainable, thanks to the plant being equipped with 3,000 solar panels on the roof, which help generate up to 70% of its energy demand.
The facility also has a geothermal network consisting of 100 points providing renewable heating and cooling, and 300 skylights providing natural light to the entire surface area. A rainwater harvesting system will in addition use rainwater to irrigate the gardens and cover the facilities' own water needs.
Global decarbonisation efforts
The company's President, Amy Davis, and the CEO of Accelera, Jennifer Rumsey, took part in the official presentation ceremony held in Guadalajara, together with the Spanish Secretary of State for Trade, Amparo López Senovilla, and the President of the Government of Castille-La Mancha, Emiliano García Page, with other political and business leaders also in attendance.
Amy Davis described this opening as “an important milestone for Accelera and a crucial step in advancing global decarbonisation efforts”. She explained that “Together with our partners, we are boosting the local economy through job creation, enabling large-scale green hydrogen production and building the infrastructure needed to make hydrogen a reliable and affordable solution to decarbonise some of the most energy-intensive industries”.
During the opening ceremony, the Spanish Secretary of State for Trade, Amparo López Senovilla, stressed that Spain's good performance as a destination for productive foreign investment is not only the result of the country's structural attractiveness. It is also due to the strategy employed and joint work carried out by the Government of Spain’s central administration, theregional governments and local bodies, which enable the best location proposals for business projects to be presented.
