An increasingly decarbonized yet resilient power grid requires the corresponding build-out of dispatchable zero-emission resources to supply peak power. However, there is a recognized dearth of solutions which can serve multi-day peak demand events both cost-effectively and with near-term deployability. Here, we find that pairing low-cost automotive fuel cells with hydrogen storage in salt caverns can serve as a peaker plant at less than 500 US$/kW at present, a fraction of the cost of conventional fossil fuel-fired peakers. We demonstrate the peaker’s value for long duration storage by comparing it with pumped hydro and assessing its profitability within Texas’ energy-only market region. Although deployment of these peakers is constrained by the presence of salt caverns, we show that a number of sites in the United States and Europe are endowed with suitable salt formations, while utilizing hydrogen storage in pressurized containers could form a location-agnostic peak power solution.

利用汽车燃料电池可以在短期内提供零排放峰值功率

日益脱碳但具有弹性的电网需要相应地构建可调度的零排放资源来供应峰值电力。然而，目前已知缺乏能够经济高效且近期可部署地为多日高峰需求事件提供服务的解决方案。在这里，我们发现，将低成本汽车燃料电池与盐穴中的储氢相结合，目前可以以低于 500 美元/kW 的价格作为调峰发电厂，而成本仅为传统化石燃料调峰装置的一小部分。我们通过将调峰器与抽水蓄能进行比较并评估其在德克萨斯州纯能源市场区域的盈利能力，展示了调峰器在长期存储方面的价值。尽管这些调峰装置的部署受到盐穴存在的限制，但我们表明，美国和欧洲的许多站点都拥有合适的盐层，而利用加压容器中的储氢可以形成与位置无关的峰值功率解决方案。
