In this study, renewable hydrogen production and blending with natural gas for the existing distribution pipelines is studied and evaluated in comparison with various fuels, such as diesel, coal, biogas, and biodiesel. In this regard, solar and wind energy-based power systems integrated with reverse osmosis units are designed and compared in energy, exergy, environment and cost, respectively. Solar PV panels and wind turbines are considered for electricity and heat. For hydrogen-based systems, an electrolyzer is utilized to produce hydrogen. The heat required for residential applications is also provided in an environmentally benign way. Here, electricity, heat, and freshwater needed in a community consisting of 100 houses are provided. The costs of capital, fuel, operation, and maintenance are calculated and evaluated in detail. An environmental impact assessment is performed by comparing carbon dioxide, carbon monoxide, unburned hydrocarbons, particulate matter, sulfur dioxide, and nitrogen oxides.
