US electrolyser start-up EvolOH Inc is planning to build its first manufacturing plant in Massachusetts with an annual capacity of up to 3.75 GW.
The facility will produce and assemble the company’s anion exchange membrane (AEM) electrolyser stacks and when fully operational, it will be the world’s largest green hydrogen electrolyser plant, the company said this week.
Work on the facility will start later in 2023, with manufacturing expected to begin in 2025.
Menlo Park, California-based EvolOH is seeking to commercialise low-cost water electrolysers. The company says its stacks are designed for a high-speed manufacturing process and use cheap, domestically available materials.
“Since EvolOH’s founding our target was not just to develop a better, less expensive electrolysis technology, but also to develop a better, less expensive electrolyser manufacturing process,” said chief executive Jimmy Rojas.
The company’s product is intended for large-scale power-to-hydrogen facilities. The power rating is up to 5 MW, or 2 tonnes of green hydrogen per day, for a single stack, and 50 MW, or 20 tonnes per day, for a single containerised module.
EvolOH also plans a second factory with an annual capacity of up to 15 GW, which is targeted to start construction in 2026.
