EvolOH will build a manufacturing plant in Massachusetts for the fabrication and assembly of EvolOH’s revolutionary anion exchange membrane electrolyzer stacks for producing green H₂. The proprietary compact cell-stacking and high power-density design used in EvolOH’s Nautilus series stacks was created for high-speed manufacturing using low-cost materials that only require domestic supply chains and no precious metals.

When operated using pure water, EvolOH’s electrolyzers provide low capital and operating costs for green H₂ production. With power ratings up to 5 MW (2 tpd) for a single stack, and 50 MW (20 tpd) for a single containerized module, EvolOH’s stacks are designed for large-scale power-to-H₂ facilities.

The Massachusetts plant will be called EvolOH’s Manufacturing Center of Excellence and will combine development facilities and staff with a single line of EvolOH’s high-speed manufacturing process. When fully operational, this facility will have a capacity for up to 3.75 GW/yr of electrolyzers, making it the largest in the world. Facility work will begin later this year with manufacturing to commence in 2025. EvolOH’s second manufacturing plant, planned to break ground in 2026, will have the capacity to make up to 15 GW/yr of electrolyzer stacks.

Dr. Jimmy Rojas, Founder and CEO of EvolOH Inc., said, “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 electrolyzer manufacturing process. Our Manufacturing Center of Excellence is the first step in those efforts, and we will continue to push the boundaries of our technology for lower cost and higher speed.”

Dr. Art Shirley, Chief Commercial Officer, EvolOH Inc., said, “The path to net zero depends on green H₂, and the electrolyzer manufacturing methods of today will never get us there. For developers announcing green H₂ mega-projects that will come on stream in the last half of this decade and beyond, electrolyzer availability is as important as cost and efficiency. EvolOH will be the supplier of choice for these customers.”
