Abstract
A spectral splitting photovoltaic-methane-steam-reforming hybrid system for heat and power cogeneration has been proposed. In the system, sunlight with wavelengths shorter than 870â¯nm is assigned to photovoltaic cells for direct power and heat cogeneration, while the rest of the solar spectrum is utilized by a methane-steam-reforming reactor via the route of solar thermal energy - chemical energy - heat and power. Analysis reveals that the hybrid system is characterized by high net solar-to-exergy efficiency (40%), high energy storage capability and low-emission energy supply (63% fossil energy saving and 77% carbon-dioxide emission reduction). Primary reasons underlying the excellent performance are full-spectrum optimized utilization of solar energy and comprehensive utilization among solar energy, thermal energy and chemical energy.
