With the decrease of the reserves of traditional fossil energy (coal, oil, natural gas), and the environmental pollution caused by the use of fossil energy, which directly threatens the survival and development of human beings, it has become a consensus at home and abroad to attach importance to and develop renewable and environmental protection energy and reduce CO2 emissions.

For different working conditions, small scenarios and large-scale applications, the system will adopt different innovative hydrogen production technologies of water electrolysis, generate hydrogen by photovoltaic power, and then store hydrogen through suitable hydrogen storage and metal alloy storage, and then generate hydrogen through fuel cells Electricity and heat or other industrial applications, especially to provide low-cost green hydrogen power generation and heating products and services for off grid households and enterprises
