On the possibilities of producing hydrogen by high temperature electrolysis of water steam supplied from biomass or waste incineration units

International audienceThe incineration of biomass and waste is considered to produce water steam, which then would feed the High Temperature Electrolysis (HTE) process in order to produce hydrogen. For these energy sources, in a French context, results show that water steam production cost could be in a range of 0.02 to 0.06 euros per steam kilogram. Potentially 78 million vehicles could be fed with hydrogen coming from the steam produced by the incineration of the currently nonvalorised biomass and domestic waste. Furthermore, for each energy source the optimized hydrogen production cost estimation has been performed, including investment and operation costs
