The solution of solar-to-hydrogen, decentralized hydrogen production and storage system for single or multi-family residential buildings is co-developed and manufactured by ZNShine’s partner Guofuhee Hydrogen. The system integrates solar power, hydrogen energy, thermal energy, lithium-ion battery, and fuel cell as a multi-energy complementary fully integrated system. The energy management system can provide electricity autonomy to meet the entire power needs of households and communities. In addition, the waste heat generated by the system is used to provide heating and hot water. The aim is to minimize the grid load by achieving low or zero grid interaction, which is realized using decentralized long-term energy storage.
