There has been a rapid acceleration in the expansion of electrolysis capacity in recent years. The previous year marked a record-breaking deployment of electrolysis technology [1]. Recovering waste heat from electrolysis and compression can improve the overall system efficiency. The integration of such waste heat into district heating systems has been investigated in literature [2], where levelized cost of heat has been used to value waste heat. However, given dynamic electricity price, time-varying hydrogen demand, potential provision of ancillary services to energy systems, time-varying thermal demand within the district heating network and the supply temperature level, the marginal cost of waste heat can vary during the day. In addition, base heat supply systems such as heat pumps are equipped to supply the heating demand. Therefore, the pricing of waste heat from a hydrogen-based system needs to be lower than the pricing of heat from heat pumps, to be accepted by consumers.
