Hydrogen technologies have experienced cycles of excessive expectations followed by disillusion. Nonetheless, a growing body of evidence suggests these technologies form an attractive option for the deep decarbonisation of global energy systems, and that recent improvements in their cost and performance point towards economic viability as well. This paper is a comprehensive review of the potential role that hydrogen could play in the provision of electricity, heat, industry, transport and energy storage in a low-carbon energy system, and an assessment of the status of hydrogen in being able to fulfil that potential. The picture that emerges is one of qualified promise: hydrogen is well established in certain niches such as forklift trucks, while mainstream applications are now forthcoming. Hydrogen vehicles are available commercially in several countries, and 225 000 fuel cell home heating systems have been sold. This represents a step change from the situation of only five years ago. This review shows that challenges around cost and performance remain, and considerable improvements are still required for hydrogen to become truly competitive. But such competitiveness in the medium-term future no longer seems an unrealistic prospect, which fully justifies the growing interest and policy support for these technologies around the world.

氢和燃料电池在全球能源系统中的作用
氢技术经历了过高期望的循环，随后幻灭了。但是，越来越多的证据表明，这些技术为全球能源系统的深度脱碳提供了有吸引力的选择，并且其成本和性能的近期改善也表明了其经济可行性。本文全面回顾了氢在低碳能源系统中可能在电力，热力，工业，运输和能源存储中发挥的潜在作用，并评估了氢在实现这一目标中的地位潜在的。出现的图景是合格的承诺之一：氢在某些领域（例如叉车）中已得到充分确立，而主流应用现在即将到来。氢车辆可在几个国家购买，并且已售出22.5万个燃料电池家庭供暖系统。与五年前的情况相比，这是一个巨大的变化。这项审查表明，围绕成本和性能的挑战仍然存在，为使氢真正具有竞争力，仍需要进行大量改进。但是，在中期的将来，这种竞争力似乎不再是不切实际的前景，这充分证明了全球对这些技术的日益增长的兴趣和政策支持。
