The system and equipment are mainly needed for the development of on-site demonstrations of key scientific research topics for distributed photovoltaic manufacturing/hydrogen storage, including materials used in electrolytic cells, gas-liquid separation systems, purification systems and auxiliary systems of alkaline water hydrogen production units, and provide system installation and debugging services and related accessories. The project combines Sinopec gas stations to form an integrated layout of hydrogen production, hydrogenation, refueling, and cogeneration of heat and power. On the one hand, it uses renewable energy photovoltaic power generation-electrolysis of water to produce hydrogen and store hydrogen, and fills hydrogen energy vehicles for application demonstration; On the other hand, it is an application demonstration of using fuel cell heat and power generation systems to supply electricity and heat energy to end users, which is also one of the important application scenarios in the non-transportation field; The entire project has the comprehensive effects of energy conservation and emission reduction, improving the ecological environment, and ensuring flexible conversion and supply of hydrogen, heat and power. By studying a medium-pressure alkaline electrolyzed water hydrogen production system suitable for photovoltaic power generation characteristics in a wide power fluctuation environment, a set of hydrogen energy storage utilization equipment integrating photovoltaic power generation off-grid hydrogen production and fuel cell co-heating has been developed. Including a 20kW photovoltaic power generation system, matching 3Nm3/h electrolyzed water hydrogen production equipment and a 2kW hydrogen fuel cell system, solves the problem of safe photovoltaic hydrogen production, smooth power generation, flexible heat supply and economical energy supply under conditions of high altitude, low air pressure, and large temperature difference between day and night. The system can meet the daily power supply and heating needs of remote agricultural and pastoral areas or residential households, and the by-product oxygen generated by hydrogen production can improve human comfort and effectively alleviate altitude reaction; at the same time, through cogeneration and energy storage, it can effectively help Clean energy consumption issues.
