Novel heat utilization materials and advanced heat recovery cycles are the key factors for the development of waste high-temperature energy utilization. Integrated systems with multiply products show significant application potential in waste thermal energy recovery.
The efficiency of generating power from waste heat recovery is heavily dependent on the temperature of the waste heat source. In general, economically feasible power generation from waste heat has been limited primarily to medium- to high-temperature waste heat sources (i.e., greater than 500 °F).
The purpose of this study is to explore the feasibility of waste heat and surplus electricity for hydrogen production and energy storage using a multi-energy complementary distributed energy system, and to analyze the energy savings, carbon reduction effect, and economic benefits of the integrated system in different types of public buildings.
