Let's understand the development prospects of photovoltaic hydrogen production industry together
Photovoltaic water electrolysis hydrogen production is a technology that combines solar power generation and water electrolysis hydrogen production into a system. It has a 40-year development history and is regarded as one of the most promising hydrogen production methods. Hydrogen production by photovoltaic power generation mainly uses the direct current generated by the photovoltaic power generation system to directly supply the hydrogen production station to produce hydrogen.
Compared with the traditional power station, the photovoltaic DC power generation system reduces the process of inversion and boosting. The main equipment and facilities include photovoltaic modules, combiner boxes, brackets, foundations, grounding devices, etc. The photovoltaic modules can be connected in series according to the input voltage and current requirements of the hydrogen production station. , parallel configuration, thereby improving system efficiency.
At present, the technology of hydrogen production by electrolysis of water is mature, the equipment is simple, the operation and management are relatively convenient, and the hydrogen produced has high purity and no pollution. However, the high cost of electricity consumption is an important reason why most companies deliberately avoid water electrolysis for hydrogen production. However, with the continuous progress of large-scale photovoltaic technology and the gradually lower electricity price, most areas are now maintained at about 0.29 yuan/kWh.
Moreover, according to incomplete statistics on the Internet, as of now, there have been 30 "green hydrogen" projects under preparation or construction across the country. Among them, more than 20 projects choose the technical route of "photovoltaic + hydrogen". With the implementation of batches of projects, the continuous expansion of photovoltaic installed capacity and the further decline of power generation costs, it is expected that photovoltaic hydrogen production will further decline in the future and enter a positive development cycle.
