Transformation towards a carbon-neutral residential community with hydrogen economy and advanced energy management strategies

• A community with renewables, microgrid, hydrogen vehicles and a station. Microgrid energy sharing to improve system efficiency under idling modes. Advanced management for flexibility grid power stability. two-stage cooling design heat recovery from an electrolyzer fuel cells. Seasonal storage annual balance via optimal synergistic powers. Cleaner production, distributed renewable generation, building-vehicle integration, associated infrastructures are promising transformation towards carbon–neutral community, whereas the academia provides limited information through integrated solutions, like intermittent network, smart operation on cell, seasonal advanced recovery. This study proposes hybrid electricity-hydrogen in California, United States, electric, thermal interactions, including low-rise houses, rooftop photovoltaic panels, vehicles, station, micro utility pipelines. strategies were proposed enhance Besides, simulation-based optimizations flows of vehicle-to-grid interaction conducted further stability cost saving. The obtained results indicate that, green renewable-to-hydrogen can effectively reduce reliance pipelines delivered hydrogen, station is effective address security concerns high-pressure participators’ acceptance. peer-to-peer Furthermore, net consumption transportation 127.0 1.2 kg/vehicle.
