Abstract: Hydrogen energy storage, with its advantages of low storage cost and low self-discharge rate, is highly suitable for seasonal energy storage. However, the low profitability of commercial operation hinders its development. This article first lists various commercial models of hydrogen energy storage. By using a mixed integer linear programming model, the optimal installation capacity and revenue of each unit under different commercial models are calculated. The optimal commercial model and relevant planning methods for hydrogen energy storage are obtained. Furthermore, based on technological advancements, the time when hydrogen energy storage can achieve commercial profitability is predicted. The study finds that hydrogen energy storage stations can achieve maximum profits through electricity price arbitrage, hydrogen sales, and the construction of renewable energy sources. When the upper limit of electricity price is 2.56 CNY/kW·h, hydrogen energy storage can achieve breakeven. Considering the cost reduction from technological advancements, hydrogen energy storage can achieve commercial profitability between 2030 and 2037. Additionally, the decrease in hydrogen fuel cell costs has the greatest impact on the pro fitability of hydrogen energy storage systems. Based on these findings, we propose to accelerate the development of electricity spot markets, improve market entry regulations related to hydrogen energy storage, and strengthen the development of hydrogen fuel cells, and thereby promote the rapid development of hydrogen energy storage industry.
