Development and assessment of a newly developed renewable energy-based hybrid system with liquid hydrogen storage for sustainable development

Abstract

One of the most effective ways to address the environmental issues triggered by fossil fuels is through the use of renewable energy. In this study, clean and sustainable power and hydrogen generation with three renewable energy sources, a wind-solar-geothermal assisted hybrid plant is planned, investigated, and analyzed. An exhaustive thermodynamic performance analysis is executed to specify the system efficiency by the way energy and exergy efficiency methods. Moreover, this developed cycle comprises a solar photovoltaic (PV) unit, a triple flash geothermal power plant, wind turbines for power generation, and a hydrogen generation and liquefaction unit. Additionally, a case study for Isparta is conducted using actual data on wind speed and solar radiation. A parametric analysis, on the other hand, is conducted to figure out the consequences of the examined cycle's performance. In light of the examination outcomes, the developed plant's power rate is figured as 9942 kW. The hydrogen generation rate and sustainability index are also figured out as 0.02143 kg/s and 2.003, respectively. Finally, the proposed hybrid cycle encloses an energetic and exergetic performance of 32.755 % and 50.06 %, respectively.
