The utilization of solar organic Rankine cycle (ORC) technology in Nepal shows promise due to its ample solar radiation. This technology should be harnessed for the purpose of generating solar energy. The academic version of engineering equation solver was used to develop simulation models, which predict the potential of solar ORC power generation across the country. The study is limited to areas with solar irradiance of 5.5 kWh/m2/day and excludes certain regions. The installation of the plant requires open land with access to water, and a 10 km2 land area was considered for the solar collector. The working fluids for the solar ORC plant are R245fa, R11, and R123. The simulation results showed a maximum overall system efficiency of 6.8%. The power output for various districts was also simulated, with Jumla having the highest power output, followed by Baitadi and Surkhet. The power output for different temperatures (90–120°C) using R245fa as the working fluid was 270, 320, 350, and 380 MW. Additionally, the study determined the cost of electricity production for the system with working fluids. The cost of electricity production was found to be 164.11$/MWh, and the levelized cost of electricity ranged from 220–265$/MWh. The payback period for the investment varies from 18 to 12 years with an internal rate of return of over 10%. Furthermore, a sensitivity analysis was conducted to ascertain the feasible investment strategies for the solar ORC system. Therefore, the study concludes that a solar ORC plant is technically feasible in Nepal for electrical power generation, with promising potential for clean energy generation.

Polymer membrane electrolyzers are a useful tool for producing hydrogen, which is a renewable energy source. Unmanned aerial vehicle (UAV) fuel cells can be powered by the hydrogen and oxygen produced by the electrolyzer. The primary losses of polymer membrane electrolyzers must therefore be identified in order to maximize their performance. A renewable-based multi-energy system considers power, cooling, heating, and hydrogen energy as utility systems for integrated sport buildings. In this study, we investigate the effect of radiation intensity, current density, and other performance factors on the rate of hydrogen production in water electrolysis using a polymer membrane electrolyzer in combination with a solar concentrator. The findings showed that a rise in hydrogen generation led to an increase in current density, which increased the electrolyzer’s voltage and decreased its energy and exergy efficiencies. The voltage was also increased, and the electrolyzer’s efficiency was enhanced by a rise in temperature, a decrease in pressure, and a reduction in the thickness of the nafion membrane. Additionally, with a 145% increase in radiation intensity, hydrogen production increased by 110% while the electrolyzer’s energy and exergy efficiencies decreased by 13.8% as a result of the electrolyzer’s high input electric current to hydrogen output ratio.
