ECONOMIC FEASIBILITY OF GREEN HYDROGEN REPLACING GRAY HYDROGEN IN CHINA'S PROVINCES BASED ON WIND AND PHOTOVOLTAIC POWER GENERATION:BASED ON DETAILED GEOGRAPHIC GRID ANALYSIS
To further study the economic feasibility of green hydrogen energy to replace gray hydrogen energy in China's provinces based on wind power generation and photovoltaic power generation,this paper uses remote sensing to analyze the occurrences of renewable energies in China's geographic grids unit,and calculates China's provinces demand for hydrogen,gray hydrogen producing cost,green hydrogen producing cost,average transporting distance and using cost,which are employed the above data to explore the economic feasibility and volumes of green hydrogen energy to replace gray hydrogen energy in China's provinces and to forecast its outlook.Wind power generation and photovoltaic power generation work well in Inner Mongolia,Xinjiang,Hebei and other individual northern provinces.In 2022,the cost of using green hydrogen in some regions of Inner Mongolia,Xinjiang,Hebei and other provinces has been lower than the cost of using gray hydrogen.China's green hydrogen energy has a total quantity 518.0 to 3 356.2 kt in replacing gray hydrogen in 2022,expected to be rising up to 41 680 to 81 760 kt in 2040 as technology on wind power generation,photovoltaic power generation and electrolyzer is advancing and carbon trading price is rising,even up to 279 000 to 480 000 kt in 2060.In 2040,the demand for hydrogen and the amount of green hydrogen produced in various provinces in China are quite different,green hydrogen production is relatively higher in Inner Mongolia,Xinjiang,Gansu and Qinghai,with a total supply of 13.52 to 34.10 million tons to other provinces,while green hydrogen production is insufficient in Ningxia,Shanxi,Sichuan and Henan,where need a 5.16 to 9.46 million tons to meet their needs.
