Abstract
The system integrates various renewable energy sources and converts it into stable power for standalone operation. The Renewable energy is then converted into Hydrogen using fuel cells to store the renewable energies in an electrochemical form. The stored Hydrogen is used to generate clean electricity by fuel cells to meet energy demand at a desired time. Renewable Energies from Solar Photovoltaic, Wind are integrated with combined Electrolysis system. Electricity from the above sources can be used to run an electrolyzer. The electrolyzer splits water into hydrogen and oxygen. The hydrogen and oxygen can be used to power a fuel cell and produce electricity. Sometimes there are low wind speeds and lesser sunny conditions and therefore power generation by solar and wind energy is reduced. The proposed system in which solar and wind energy is integrated with fuel cell to provide a continuous power supply to a small local load to enhance Reliability of power supply and stores the excess energy in to hydrogen and oxygen. Here PV and wind energy is used as the primary source of power with the fuel cell section acting as a power backup system. Renewable energy portability and long term storage of renewable energies are achieved in the proposed system
