Performance Analysis of a Zero-Energy Building Using Photovoltaics and Hydrogen Storage

The exploitation of renewable energy sources in the building sector is a challenging aspect achieving sustainability. incorporation proper storage unit vital issue for managing properly electricity production and so to avoid use grid electricity. present investigation examines zero-energy residential that uses photovoltaics covering all its needs (heating, cooling, domestic hot water, appliances-lighting needs). reversible heat pump an electrical heater, there not any need fuel. novel analysis lies utilization hydrogen as technology power-to-hydrogen-to-power design. residual from feeds electrolyzer which stored tank under high pressure. When electricity, are enough, used fuel cell producing needed work 400 m2 floor area Athens with total yearly demand 23,656 kWh. It was found 203 capacity 34 m3 can make autonomous year period.
