Ceres electrolyser tests signal 25pc efficiency gain

Electrolyser and fuel-cell manufacturer says initial tests on new modular technology yield positive results

Solid-oxide electrolyser and fuel-cell manufacturer Ceres says initial testing of its new electrolyser module indicates it can deliver green hydrogen around 25pc more efficiently than existing, lower-temperature technologies. Testing is underway on a 100kW version of the technology, ahead of scaling up to a 1MW demonstrator.  “Initial results are positive and give confidence that this technology can deliver green hydrogen at <40kWh/kg, around 25pc more efficiently than incumbent lower temperature technologies,” Ceres says in a trading update. The company expects 2022 revenue and other operating income to be in line with previous guidance of £21mn ($25.78mn)—a 34pc fall year-on-year—with a
