Integration of Solar PV and GH2 in the Future Power Systems

Green hydrogen (GH2) is an influential renewable energy technology in the future of renewable energy use that aims to increase the production of green hydrogen, a clean fuel that can help to decarbonize and enhance energy systems. Green hydrogen can also enhance the flexibility of power systems that integrate renewable energies (REs), such as solar and wind. One way to develop a decentralized power system is to integrate solar photovoltaic (PV) with GH2. This system can provide power during the day from solar PV and the night from GH2, which can also store excess energy. This can increase energy independence and reduce the risk of power outages caused by centralized power grids. In this research, optimal strategies in the exploitation of decentralized integrated power systems consisting of hydrogen storage systems and renewable energy production based on solar PV have been investigated and the technical and economic effects of the joint launch of hydrogen energy storage (HES) and solar PV and participation in the electricity market to achieve profitability are evaluated.
