The Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE) awarded a $99,550,000 Cooperative Agreement to Proton Energy Systems Inc., doing business as Proton Onsite, under the Renewable Energy Research and Development (CFDA 81.087) federal grant program. The goal of this award is to build the world's first fully automated pilot Proton Exchange Membrane (PEM) electrolyzer production line with a capacity of 500 MW per year. This will result in a repeatable design to serve as the technical basis for future PEM electrolyzer manufacturing expansion and achieve stack costs of $300/kW. The project will be completed by September 30, 2025.
