Underground Natural Gas Storage Market Report 2026

The underground natural gas storage market size has grown strongly in recent years. It will grow from $339.93 billion in 2025 to $358.14 billion in 2026 at a compound annual growth rate (CAGR) of 5.4%. The growth in the historic period can be attributed to seasonal gas demand fluctuations, growth of natural gas consumption, price volatility management needs, expansion of pipeline networks, government energy security policies.

The underground natural gas storage market size is expected to see strong growth in the next few years. It will grow to $436.25 billion in 2030 at a compound annual growth rate (CAGR) of 5.1%. The growth in the forecast period can be attributed to hydrogen blending initiatives, demand for grid balancing, expansion of LNG infrastructure, decarbonization transition needs, digital monitoring of storage assets. Major trends in the forecast period include rising investment in energy storage infrastructure, growing use of salt cavern storage facilities, expansion of strategic gas reserves, increasing integration with smart grid systems, higher focus on supply security and reliability.

The growing production of natural gas is anticipated to drive the expansion of the underground natural gas storage market in the future. Natural gas primarily consists of methane (CH₄), along with small amounts of other hydrocarbons like ethane, propane, and butane, which are viewed as cleaner alternatives to other fossil fuels. Several factors, such as the shift to cleaner energy, industrial growth, and the need for energy security, are fueling the rising demand for natural gas. Underground storage helps manage natural gas supply fluctuations by storing excess gas during periods of low demand and releasing it during high-demand peaks, ensuring price stability and a reliable supply. Additionally, it aids in maintaining grid stability and supports renewable energy integration by offering backup when renewable power generation is insufficient. For example, in September 2024, the U.S. Energy Information Administration (EIA) reported that U.S. dry natural gas production reached 37.8 trillion cubic feet (Tcf) in 2023, or 103.6 billion cubic feet per day (Bcf/d), marking a 4.3% increase from the 2022 production of 99.3 Bcf/d. As a result, the growing production of natural gas is expected to fuel the growth of the underground natural gas storage market.

Leading companies in the underground natural gas storage sector are focusing on developing advanced solutions, such as the hydrogen storage salt caverns initiative, to enhance energy security and lower carbon emissions. This initiative aims to leverage the unique properties of salt deposits to store hydrogen securely and efficiently. For instance, in March 2024, the European Consortium, a UK-based association of 17 partners led by Storengy, a UK-based natural gas storage company, launched the FrHyGe project. Funded by the European Union's Clean Hydrogen Partnership, the project has a budget of €43 million ($46.91 million) and aims to validate large-scale underground hydrogen storage in salt caverns. The project plans to build an industrial prototype in Manosque, France, and explore replication in Harsefeld, Germany, with potential applications across Europe. Key objectives include converting natural gas or brine salt caverns into hydrogen storage facilities, demonstrating the capability to inject and withdraw 100 metric tons of hydrogen over cycles ranging from one hour to one week, exploring market penetration and supply chains, and planning for replication at other European sites. Additionally, the project will assess environmental impacts, safety criteria, and regulatory requirements ahead of deployment on the GeoH2 (Manosque) and SaltHy (Harsefeld) projects.

In January 2024, Williams, a US-based oil and gas company, acquired a portfolio of natural gas storage assets from Hartree Partners LP for $1.95 billion. This acquisition included six underground storage facilities in Louisiana and Mississippi with a combined capacity of 115 billion cubic feet (Bcf), as well as 230 miles of gas transmission pipelines and 30 pipeline interconnects, connecting to key markets including LNG and Transco. Hartree Partners LP is a US-based company that specializes in underground natural gas storage facilities.
