Bloom has deployed more than 1GW of fuel cells
Bloom demonstrates largest solid-oxide electrolyser
The 4MW system can produce 20–25pc more hydrogen per MW than low-temperature electrolysers
Electrolyser manufacturer Bloom Energy has started up its largest solid-oxide electrolyser (SOE) to date at the Nasa Ames Research Center in California. The 4MW system is capable of producing 2.4t/d of hydrogen, 20–25pc more hydrogen per MW than equivalent commercial low-temperature electrolysers. Bloom has previously tested a 100kW SOE at the Department of Energy’s Idaho National Laboratory, where it simulated nuclear power conditions and demonstrated production using 37.7kWh per kg of hydrogen. This pilot produced hydrogen at more than 25pc greater efficiency than low-temperature electrolysers. Bloom was originally spun off from a Nasa test project in the 2000s to develop a system that cou
