摘要/Abstract

摘要：

我国沿海地区经济发达,能源需求量大,探索海上风电制氢为其他行业供能具有现实意义。比较了海上风电输电上岸后的两种利用模式:1)风电售电模式;2)风电制氢模式。首先通过比较碱性(alkaline,ALK)电解槽和质子交换膜(proton exchange membrane,PEM)电解槽的工作特性,建立了制氢系统产氢量模型。其次,建立两种模式的经济分析模型;最后,结合净现值和平准化制氢成本比较了不同风能利用模式的经济性。结果表明在当前技术情景下,氢价取46.93元/kg、风电上网电价取0.531 8元/(kW·h)时,风电制氢模式比风电售电模式更具有经济性,氢价是影响制氢模式经济性的最大因素,而氢价取决于未来氢市场的供需关系,不确定性较大。

Abstract:

The coastal areas of China are economically developed and have a large energy demand. It is of practical significance to explore the production of hydrogen using offshore wind power to supply energy to other industries. This paper compares two utilization modes of offshore wind power after transmission on shore, i.e., direct sales and use for hydrogen production. Firstly, by comparing the power characteristics of alkaline (ALK) and proton exchange membrane (PEM) electrolyzers, the hydrogen production model is established. Secondly, the economic models of the two modes are established. Finally, the economy of different wind energy utilization modes are compared using net present value (NPV) and levelized cost of hydrogen production (LCOH). The results show that, under the current technical scenario, when the hydrogen price is 46.93 yuan/kg and the feed-in electricity price of wind power is 0.5318 yuan/(kW·h), the wind power used for hydrogen production is more economical than the wind power sales mode. The hydrogen price is the biggest factor affecting the economics of the hydrogen production model, where the hydrogen price depends on the supply and demand relationship in the future hydrogen market, and there is great uncertainty.

Key words: consumption mode of offshore wind power, wind power sales, hydrogen production using wind power, cost-benefit analysis, levelized cost of hydrogen
