EvolOH

EvolOH is a cleantech company that manufactures electrolyzer stacks for green hydrogen production. The company's Nautilus platform utilizes liquid alkaline technology and is designed using abundant materials like steel, plastic, and aluminum, eliminating the need for precious metals or rare earth materials. EvolOH's electrolyzers feature a compact cell-stacking and high-power density design created for high-speed manufacturing. The company's stacks can be configured into modules of 24 megawatts, making them suitable for large industrial applications. EvolOH's manufacturing process uses roll-to-roll printing, a technique adapted from battery manufacturing, to produce both electrodes and membranes efficiently. The company is building a Manufacturing Center of Excellence in Massachusetts with an annual capacity of 3.75 GW of electrolyzers, with manufacturing scheduled to commence in 2025. A second manufacturing plant, planned to break ground in 2026, will have a capacity of 15 GW per year. EvolOH's manufacturing facility is designed to offer an 80% reduction in capital investment and footprint compared to traditional methods. The company's electrolyzer stacks can achieve power ratings up to five MW for a single stack and 50 MW for a single containerized module.

Key customers and partnerships

In March 2024, EvolOH formed a strategic partnership with 3 million to leverage their expertise in high-volume membrane electrode assembly. The company also collaborates with various power supply companies, pump manufacturers, and heat exchanger providers to source readily available components for their systems.
