EVOLOH, Inc., a cleantech company that manufactures electrolyzer stacks for H₂ production, announced it has reached important commercial and technical milestones on its path to making low-carbon H₂ globally accessible. EVOLOH’s scalable, high-throughput manufacturing technology and high efficiency NautilusTM platform of advanced liquid alkaline electrolyzers represent a step change in green H₂ production.

EVOLOH has signed a supply agreement with a large, US-based renewable energy developer for half a gigawatt (0.5 GW) of electrolyzer stacks. The supply is secured through a non-refundable deposit that applies to the purchase cost once EVOLOH completes its Lowell, MA Manufacturing Center of Excellence.

“This agreement is a recognition of the tremendous benefits of EVOLOH’s electrolyzer technology and manufacturing process and comes on top of more than sixteen gigawatts (16 GW) of signed intent for supply of Nautilus stacks and modules,” said Dr. Jimmy Rojas, founder and CEO of EVOLOH. “Using only local supply chains for commodity raw materials, high-speed roll-to-roll processing, and the most power-dense stack design in the industry, EVOLOH can produce in a few weeks what would take other electrolyzer manufacturers months to supply.”

The supply agreement comes at the same time EVOLOH is commissioning a new pilot testing facility located at the company’s headquarters in Santa Clara, CA. EVOLOH moved into the 25,000 square-foot building in September of this year.

“In Santa Clara, we’re currently operating dozens of stations at power ratings of tens of kilowatts (10s kW) for pilot testing, and we’ll soon be able to test stacks for up to several hundred kilowatts (100s kW),” said Rojas. To the testing capabilities in Santa Clara, EVOLOH is adding in 2025 a pilot facility in Lowell, MA for factory acceptance testing of full stacks up to one megawatt (1 MW) in power consumption. Commercial demonstration projects of multiple megawatts are also in negotiation with several developers to be commissioned beginning in 2026.

To fund the expansion of pilot facilities and commercial demonstrations, EVOLOH has increased its funding via additional grants, notes and equity. “To date, we’ve raised over $40 million, much of it non-dilutive, to ensure that we can deliver on large-scale supply of the most advanced electrolyzers on the market,” explained Rojas. “Our investors recognize the massive value of our low-cost approach to manufacturing and commercializing electrolyzers and continue to support us through this exciting time.”
