The 220MW Advanced Clean Energy Storage (ACES Delta) project in Utah, US, has reached a key milestone, with all 40 electrolysers supplied by Norwegian company HydrogenPro now running at full load and producing green hydrogen.

HydrogenPro confirmed the facility's readiness to convert and store up to 100 tonnes per day (tpd) of hydrogen. Jointly developed by Chevron New Energies and Mitsubishi Power, the hub uses renewable power to generate hydrogen for storage in two salt caverns – each holding 150 gigawatt-hours – for dispatch to California's grid.

HydrogenPro CEO Jarle Dragvik described the project as having groundbreaking technology with outsized impact on regional power supply. He highlighted its role in decarbonisation and the company's delivery track record amid rising demand for low-cost green hydrogen, which is projected to hit 5.5–10 million tonnes per annum globally by 2030.

The site's cavern storage capacity currently dwarfs all US grid-connected batteries combined, positioning ACES as a utility-scale benchmark for renewable hydrogen integration into power systems.
