Energetic and exergetic performance analysis of a multigeneration system including thermoelectric generators

Project: Research

Project Details


There is need to increase contribution of renewable energy to overall electricity generation. Thermoelectric generators can be considered as one of the renewable energy devices which convert waste heat directly into the electricity. Its integration with the solar energy is very fruitful because of the abundant availability of the solar energy, particularly in Saudi Arabia. Thermoelectric devices are an attractive option for power generation when integrated with solar heating. Therefore in this research proposal, we intended to develop a multigeneration system with improved overall performance of the photovoltaic (PV) hydrogen production by incorporating thermoelectric coolers driven through the electricity generated by the thermoelectric generators. In addition to this, low efficiency of thermoelectric generators/coolers will be mitigated by the integration of rejected heat in multigeneration system. Upto the authors best knowledge, similar kind of work has not been reported in the literature yet. The primary objective of this research is to improve understanding, by performing thermodynamic modeling and an exergy analysis, of a novel integrated solar energy-based system for multigeneration which will include: an organic Rankine cycle (ORC), an absorption chiller, heat pump and electrolyzer. Electricity will generated for remote (Off Grid) areas of Saudi Arabia where the temperature of the photovoltaic panels becomes too high and efficiency becomes low in summer. Heat will be generated for industrial use, cooling for cold storage of food, thermal energy storage system (TES) for hot water supply for domestic/industrial usage even at night when solar energy is not available and hydrogen for storage.
