A group of researchers from Ontario Tech University in Canada has developed an innovative multigeneration energy system that can provide five outputs: electricity, hydrogen, cooling, heating, and hot water. This system, primarily powered by a solar heliostat system, incorporates technologies like compressed air and pumped hydro storage for surplus power storage. The operation involves using thermal energy from the solar heliostat to generate electricity via a Rankine cycle, while microbial electrolysis cells produce hydrogen from wastewater. Additional features include a cooling cycle for residential and industrial use, as well as pumped hydro storage to manage excess energy. Simulations in Kalgoorlie-Boulder showcased high efficiencies and multiple output capabilities of the system. The researchers also suggested adaptability for different regions and the integration of wind energy. The system's performance metrics were impressive, demonstrating effective energy and exergy efficiencies during both charging and discharging modes. The study emphasizes the need for a thorough techno-economic analysis to evaluate the financial viability of the system.
