Abstract：The average altitude of Xizang Plateau is more than 4000 meters,and the plateau hypoxia environment has caused serious harm to the health of people in Xizang.In order to improve the living environment in Xizang and the healthy living standards of people in Xizang,the government of Xizang Autonomous Region is vigorously developing the oxygen production and supply industry and implementing oxygen supply projects.At present,civil oxygen production in Xizang mainly uses pressure swing adsorption(PSA)oxygen production and purchases liquid oxygen from areas outside the Xizang Autonomous Region.PSA oxygen production has high failure rate,low energy efficiency and high cost due to high altitude and low pressure in Xizang,and liquid oxygen has high cost due to high freight.Xizang is rich in solar energy resources.The use of solar photovoltaic power generation to electrolyze water to produce oxygen is not affected by low pressure in plateau.At the same time,it can produce hydrogen,so that the preparation of oxygen can be closely linked with the development and utilization of solar energy resources and the development of hydrogen energy.That is,Xizang's resource advantages can be transformed into development advantages,while meeting the oxygen demand of people in Xizang,which is in line with national policy guidance.It is a green energy economy suitable for the development of Xizang,and an opportunity and a good way to promote high-quality development of Xizang's economy and society.
