EvolOH to build World’s Largest Green Hydrogen Electrolyzer Manufacturing Plant

MENLO PARK, CA, February 27, 2023 / EvolOH, Inc., a cleantech company, announced today that it will build a manufacturing plant in Massachusetts for the fabrication and assembly of EvolOH’s revolutionary anion exchange membrane (AEM) electrolyzer stacks for producing green hydrogen. The proprietary compact cell-stacking and high power-density design used in EvolOH’s NautilusTM 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 the lowest capital and operating costs for green hydrogen production. With power ratings up to 5 MW (2 tonnes per day) for a single stack, and 50 MW (20 tonnes per day) for a single containerized module, EvolOH’s stacks are designed for large-scale power-to-hydrogen 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 per year of electrolyzer stacks, 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 per year of electrolyzer stacks.

About EvolOH

EvolOH Inc., a private green hydrogen technology company, is at the forefront of the development and commercialization of low-cost and mass-produced water electrolyzers. The company’s patent-pending electrolyzers incorporate a design for high-speed, low-cost manufacturing, making green hydrogen production possible at gigawatt scale.

NautilusTM is EvolOH’s earth-abundant, pure water electrolyzer stack platform, designed from the ground-up with the system integrator in mind. Highly scalable and based on a consistent core cell architecture, NautilusTM offers single-unit stack capacities from 20 through 2,000 kg/day and packaged stack modules of 10 and 20 tonnes per day with the smallest footprint and lowest water pressure drop in the industry.
