The 5.5MW single-stack pressurised alkaline electrolyser is being validated in two stages at Mitsubishi Power’s Takasago Hydrogen Park in the Hyogo Prefecture.
A single unit was installed and tested at the Herøya Industrial Park in Norway, where the short-term validation culminated in a 96-hour baseload run.
The technology is now undergoing long-term validation at full load and in real-world conditions at a permanent installation in the Takasago Hydrogen Park, where the electrolyser will be operated under the same conditions as it would operate commercially.
The full-scale validation aims to minimise technology risk and includes performance, operations, start-ups, shutdowns, gas quality, safety and digital control integration.
The Advanced Clean Energy Storage (ACES Delta) project in Utah, USA, is a joint venture between Chevron and Mitsubishi Power Americas.
ACES Delta will produce, store and deliver green hydrogen from 2025, using renewable energy-powered electrolysers. Two salt caverns will each store 150GWh of the hydrogen produced for dispatch to the grid when needed.
