The performance envelope for an electrolyser system is developed and explored. The reversible HT- and NT-electrolyser performance can be described using reversible thermodynamics. The benefits of using the high temperature (HT) electrolyser are discussed. If we simplify the reversible process by replacing the reversible heat engines with a heat exchanger assembly we identify a demand of additional heat for evaporation if using a HTelectrolyzer by considering the system integration while NT-electrolyzer use electric work for supplying needed reaction heat.
