Hydrogen Energy Storage: Prospects and Commercialization Challenges

This document analyzes the prospects and commercialization difficulties of hydrogen energy storage. It begins with China's policy background, highlighting the 'dual carbon' goal and over 560 hydrogen-specific policies by end of 2024, including the Energy Law. Hydrogen energy storage is overviewed as a long-cycle, large-capacity solution for renewable energy consumption and grid peak shaving, with applications in distributed power stations, hydrogen refueling, and combined heat and power. Key commercialization challenges include high costs of water electrolysis, hydrogen storage, and transportation technologies. The document emphasizes the need for supportive electricity pricing, market mechanisms, and pricing mechanisms for hydrogen storage. It concludes that hydrogen energy storage is crucial for China's energy transition but requires technological breakthroughs and policy support to achieve commercial viability.
