Although the economics of producing hydrogen from water electrolysis are currently dominated by the cost of electricity, electrolyzer capital costs will become much more important in a renewable energy future when very-low-cost electricity will be available for a small fraction of the day. Due to their potential for simple construction and high current densities, membraneless electrolyzers represent a promising approach to driving down capital costs to the levels required for water electrolysis to compete with steam methane reforming. This article highlights the challenges and opportunities for membraneless electrolyzers to become a disruptive technology in a renewable energy future.

可再生能源未来低成本生产氢气的无膜电解槽

尽管目前由水电解生产氢气的经济性主要由电力成本决定,但在可再生能源的未来中,当一天中的一小部分可用成本非常低廉的电力时,电解器的资本成本将变得更加重要。由于无膜电解器具有结构简单和电流密度高的潜力,因此是一种将资本成本降低至水电解与蒸汽甲烷重整竞争所需水平的有前途的方法。本文重点介绍了无膜电解槽成为可再生能源未来的破坏性技术所面临的挑战和机遇。
