1. The power consumption of the electrolyser is 315 kilowatts. 2. This effectively allows the electrolyser to operate at more than 100 % electrical efficiency. 3. Electrolyser vendors provide efficiencies based on enthalpy.4. Potentially, an electrolyser operating at 1.48 V would be 100 % efficient. 5. ITM Power has supplied its HGas electrolyser units in several power-to gas projects. 6. Some hospitals have installed combined electrolyser -storage-fuel cell units for local emergency power. 7. This could be reversed so that it acted as both an electrolyser and a fuel cell. 8. The electrolyser produces 210 Nm 3 / h of hydrogen and is operated by RH2-WKA. 9. ITM Power has also recently sold a 1MW electrolyser system and additional equipment to ZEAG Energie AG by competitive tender. 10. In August 2013, a 140 MW wind park in Grapzow, Mecklenburg-Vorpommern, owned by E . ON received an electrolyser .
