Bloom Energy has begun generating hydrogen from the world’s largest solid oxide electrolyzer installation at NASA’s Ames Research Center, the historic Moffett Field research facility in Mountain View, Calif. This high-temperature, high-efficiency unit produces 20-25% more hydrogen per megawatt (MW) than commercially demonstrated lower temperature electrolyzers such as proton electrolyte membrane (PEM) or alkaline.
This electrolyzer demonstration showcases the maturity, efficiency and commercial readiness of Bloom’s solid oxide technology for large-scale, clean hydrogen production. The 4 MW Bloom Electrolyzer™, delivering the equivalent of over 2.4 metric tonnes per day of hydrogen output, was built, installed and operationalized in a span of two months to demonstrate the speed and ease of deployment.
“This demonstration is a major milestone for reaching net-zero goals,” said KR Sridhar, Ph.D., Founder, Chairman and CEO of Bloom Energy. “Hydrogen will be essential for storing intermittent and curtailed energy and for decarbonizing industrial energy use. Commercially viable electrolyzers are the key to unlocking the energy storage puzzle, and solid oxide electrolyzers offer inherently superior technology and economic advantages. Bloom Energy, as the global leader in solid oxide technology, is proud to share this exciting demonstration with the world: our product is ready for prime time.”

The current demonstration expands on Bloom’s recent project on a 100 kW system located at the Department of Energy’s Idaho National Laboratory (INL) which achieved record-breaking electrolyzer efficiency. In the ongoing project, 4500 hours of full load operations have been completed with a Bloom Electrolyzer™ producing hydrogen more efficiently than any other process – over 25% more efficiently than low-temperature electrolysis.
The INL steam and load simulations replicated nuclear power conditions to validate full capability of technology application at nuclear facilities, and the pilot results revealed the Bloom Electrolyzer producing hydrogen at 37.7 kWh per kg of hydrogen. Dynamic testing conducted at INL included ramping down the system from 100 percent of rated power to 5 percent in less than 10 minutes without adverse system impacts. Even at 5 percent of rated load, the energy efficiency (kWh/kg) was as good or better than other electrolyzer technologies at their 100% rated capacity. These results will be presented at the Department of Energy’s Annual Review Meeting in Washington DC on June 7, 2023.
