Hydrogen is an important part of any discussion on sustainability and reduction in emissions across major energy sectors. In addition to being a feedstock and process gas for many industrial processes, hydrogen is emerging as a fuel alternative for transportation applications. Renewable sources of hydrogen are therefore required to increase in capacity. Low-temperature electrolysis of water is currently the most mature method for carbon-free hydrogen generation and is reaching relevant scales to impact the energy landscape. However, costs still need to be reduced to be economical with traditional hydrogen sources. Operating cost reductions are enabled by the recent availability of low-cost sources of renewable energy, and the potential exists for a large reduction in capital cost withmaterial and manufacturing optimization. This article focuses on the current status and development needs by component for the low-temperature electrolysis options.

低温电解和大规模可再生氢潜力的观点。

氢是有关主要能源部门的可持续性和减少排放的任何讨论的重要组成部分。除了作为许多工业过程的原料和工艺气体外，氢气还正在成为交通运输应用的燃料替代品。因此需要可再生的氢源以增加容量。低温电解水是目前最成熟的无碳氢生成方法，并且正在达到相关规模以影响能源格局。然而，仍然需要降低成本以使用传统的氢源经济。最近可以使用低成本的可再生能源，从而降低了运营成本，并且存在通过材料和制造优化来大幅度降低资本成本的潜力。
