摘要: 远海风资源丰富,可用于发展更大装机容量的风电场,具备发展氢储能应用的潜力。输电工程和制氢工程是远海风电开发利用的2种途径。首先建立了远海风电输电工程的全寿命周期成本模型。其次,推导了质子交换膜(proton exchange membrane,PEM)电解槽能量效率的计算过程,基于PEM电解槽的“功率-效率”特性模型,评估氢气产量,建立远海风电制氢工程的全寿命周期成本模型。最后结合算例评估了2种途径的经济效益。

Abstract: The rich off-shore wind resources can be exploited to build wind farms with larger installed capacity, which has shown great potential to develop hydrogen energy storage applications. Power transmission and hydrogen production are the two ways to develop and utilize offshore wind power. Firstly in this paper, a life-cycle cost model for offshore wind power transmission is established. Secondly, the energy efficiency calculation process of the proton exchange membrane (PEM) electrolyzer was derived. Based on the "power-efficiency" characteristic model of the PEM electrolyzer, the hydrogen production yield was assessed, and the life-cycle cost model of the off-shore wind power hydrogen production project was formulated. Finally, case studies are conducted to evaluate the economic benefits of these two approaches respectively.

Key words: offshore wind farm, transmission project, hydrogen production, economic analysis, hydrogen production efficiency
