Summary: Urbanization and population growth have significantly impacted global energy demands. The use of non-renewable fossil fuel-based energy infrastructure leads to air pollution, global warming, greenhouse gas emissions, acid rain, diminishing energy resources, and environmental degradation. This necessitates the exploration of alternative energy sources. Hydrogen, as an efficient energy carrier, has gained scientific attention as an alternative fuel to meet energy demands. This review focuses on hydrogen production from renewable sources (such as biomass, solar, wind, geothermal, and algae) and conventional non-renewable sources (including natural gas, coal, nuclear, and thermochemical processes). Additionally, the cost analysis for hydrogen production from each energy source is discussed. Finally, the environmental impact and implications of these hydrogen production processes are summarized.

Summary: This study evaluated the potential benefits of thermally integrating a membrane distillation heat exchanger (MDHX) with water electrolysis for thermal management of waste heat and simultaneous production of fresh water for hydrogen production. A MATLAB model was used to simulate a combined MDHX and water electrolysis stack, showing that the MDHX-EC system can regulate the temperature of an AEM electrolyser and produce fresh water at the same rate as water consumption. These results suggest that further experimental studies should be conducted to explore the performance and economic benefits of this integrated system.
