The global underground hydrogen storage market demand was estimated at 2,780.67 MCM in 2024 and is projected to reach 6,249.05 MCM by 2033, growing at a CAGR of 9.2% from 2025 to 2033. The market is expected to expand steadily over the forecast period, driven by supportive government policies, rising net-zero emission targets, and an increasing focus on hydrogen as a clean energy carrier across industrial, transportation, and power generation sectors.
Growing investments in green hydrogen infrastructure and the accelerating adoption of renewable energy sources are fueling demand for safe, scalable hydrogen storage solutions. Underground hydrogen storage involves the containment of hydrogen gas in large geological formations such as salt caverns, depleted oil and gas fields, and aquifers, enabling efficient balancing of hydrogen supply and demand in large-scale hydrogen energy systems. This approach supports long-duration energy storage, which is critical for stabilizing hydrogen supply chains and enabling fully decarbonized energy grids.
Furthermore, advancements in subsurface engineering technologies and the repurposing of existing natural gas storage infrastructure are strengthening the commercial viability of underground hydrogen storage solutions.
