Currently, the cost of electricity for electrolysis of producing hydrogen is about 70–90% of the total cost. Scientists predict that the share of renewable energy in total energy is expected to reach about 70% in 2050, as the cost of wind photovoltaic power generation in China is as low as 0.13¥/(kW·h), and that the use of renewable energy sources, mainly photovoltaic and wind power, of producing hydrogen can effectively reduce the cost of electricity. Meanwhile, with the improvement of technology, the cost of an electrolyzer used in proton exchange membrane hydrogen production technology can be reduced by about 50%, which will reduce the cost of hydrogen production by more than 20%. According to the distribution of electricity resources in each region of China, the project construction of renewable energy power generation and proton exchange membrane hydrogen production can be reasonably carried out. A long-distance hydrogen transmission system can be established to provide guaranty for the establishment and operation of urban hydrogen power stations using a combination of renewable energy and long-distance hydrogen transmission systems. This paper provides a reference for the industrial development and policy direction of hydrogen production by water electrolysis.

我国水电解制氢潜力分析
目前，电解制氢的电力成本约占总成本的70-90%。科学家预测，2050年可再生能源占能源总量的比重有望达到70%左右，因为我国风电光伏发电成本低至0.13元/(kW·h)，而且利用可再生能源制氢的能源主要是光伏和风电，可以有效降低电力成本。同时，随着技术的改进，质子交换膜制氢技术所采用的电解槽成本可降低50%左右，这将使制氢成本降低20%以上。根据我国各地区电力资源分布情况，可再生能源发电和质子交换膜制氢项目建设得以合理开展。可建立长距离输氢系统，利用可再生能源与长距离输氢系统相结合，为城市氢电站的建设和运营提供保障。该文为水电解制氢的产业发展和政策方向提供参考。
