Alfa Laval to Supply Cooling Equipment for Onuba H2 Electrolyzer Plant – News and Statistics

Sep 25, 2026

Alfa Laval will serve as the technology supplier for cooling equipment tied to electrolyzers at the Onuba H2 project, a flagship effort inside the Andalusian Green Hydrogen Valley, as reported by Hydrogen Central. Moeve leads the initiative, which is characterized as Southern Europe’s biggest renewable hydrogen undertaking.

Situated at the La Rabida Energy Park in Huelva, Onuba H2 is poised to rank as Southern Europe’s largest electrolyzer facility. Its starting electrolysis capacity stands at 300 MW, with room to add another 105 MW, and yearly output of green hydrogen is projected at 45,000 tonnes.

Serving as the industrial cornerstone of the Andalusian Green Hydrogen Valley, the project is expected to help cut emissions in transport and industry. Moeve will receive heat transfer apparatus from Alfa Laval for the plant, spanning balance of plant cooling, electrolyzer cooling, and gas cooling. In total, the order covers 60 heat exchangers from Alfa Laval.

Per the source, such cooling systems are essential for keeping the electrolyzer within ideal operating parameters, safeguarding efficiency, dependability, and safety during large-scale renewable hydrogen output.

Thomas Moller, who heads the Energy Division at Alfa Laval, stated that his company takes pride in lending its know-how and technology to Onuba H2, which he described as being at the leading edge of Europe’s energy shift. He further noted that Alfa Laval’s heat transfer offerings are built to further the bold aims of decarbonizing industry and transport while bolstering Europe’s energy security.

The Andalusian Green Hydrogen Valley has been designated a Project of Common Interest by the European Commission, highlighting its strategic value for the entire EU. That status opens the door to public grants and subsidies, speeding up the ecological transition and strengthening Europe’s energy security.

Renewable hydrogen is portrayed as a crucial energy carrier for meeting the CO2 reduction objectives established by the European Union. By making it possible to decarbonize sectors that resist electrification, including heavy transport and energy-intensive industry, Onuba H2 is set to deliver a meaningful contribution toward Europe’s climate targets and energy independence.

Andalusia’s distinctive mix of plentiful renewable resources, solid infrastructure, and advantageous geography places it as a worldwide frontrunner in green hydrogen output. Onuba H2 illustrates how the region can propel the energy transition, both within Spain and throughout Europe.
