In an era marked by fluctuating energy markets and geopolitical tensions, the importance of underground gas storage (UGS) has never been more pronounced. As the backbone of global gas security, UGS facilities play a critical role in balancing supply and demand, mitigating price volatility, and ensuring a stable energy supply during peak consumption periods. The recent global gas crisis has thrust UGS into the spotlight, prompting accelerated growth and renewed investment in this vital infrastructure.

By the end of 2023, the global working gas capacity of UGS reached 437 billion cubic meters (bcm), a 2% year-on-year increase—the largest since 2015. This surge is primarily due to significant capacity expansions in China, with additional contributions from Europe, Kazakhstan, and Canada. The number of operational UGS facilities globally stood at 681, with China commissioning five new facilities and Saudi Arabia adding its first. The global peak withdrawal rate also increased by 1.6% to 7,516 million cubic meters per day (mcm/d).

The CEDIGAZ 2023 report highlights significant shifts in the global gas market, with a 1.3% increase in Underground Gas Storage (UGS) capacity, driven by the global gas crisis. Major contributors include China and Europe, with a focus on expanding storage in rapidly developing markets like the Middle East. The report notes a 20% growth in UGS projects in 2022, reflecting the sector's growing importance in natural gas supply security.

The global energy crisis, especially due to Russia's invasion of Ukraine, has reshaped the gas market, leading to more flexible and price-sensitive LNG trade. Governments globally are focusing more on natural gas security, introducing stricter storage regulations and strategic LNG reserves. Japan proposed an international cooperation framework to enhance LNG security.

Europe's RePowerEU plan, a response to Russian aggression, seeks to lessen reliance on Russian fossil fuels, mandating higher gas storage levels. In 2022, storage exceeded EU regulations, reaching 95% by November. Other regions, including Ukraine, the US, China, and the Middle East, are also advancing in UGS, adapting to their specific market needs.

This annual report assesses underground gas storage (UGS) in the world at the end of 2021. It is based and complemented by a comprehensive online database, including detailed statistical information on current and future capacities for the 667 UGS facilities in operation in the world and the 166 UGS projects under construction, planned or potential. Altogether, the database includes 51 countries. The database also includes information on closed, mothballed and inactive UGS facilities, as well as the expansion stages of UGS facilities, when this information is available (see Methodology). The database is available to CEDIGAZ’s members under the infrastructure section of CEDIGAZ website.

This report includes two parts. The first one gives an assessment of UGS capacity at the end of 2021 and new capacity under construction, planned and potential. The second part reviews major trends in UGS in selected key markets: Europe, Ukraine, Russia, the United States, and China. In view of the crucial role of gas storage for security of supply, this review includes an analysis of gas stocks in 2021/22 and winter 2022/23 preparedness. In addition, recent UGS construction activity is reviewed in Central and South America and the Middle East.

This report is based on information available at the beginning of November 2022.

This annual report assesses underground gas storage (UGS) in the world at the end of 2020. It is based and complemented by a comprehensive online database, including detailed statistical information on current and future capacities for the 661 UGS facilities in operation in the world and the 91 new projects under construction, planned or potential. Altogether, the database includes 51 countries. The database also includes information on closed, mothballed and inactive UGS facilities, as well as the expansion stages of UGS facilities, when this information is available (see Methodology). The database is available to CEDIGAZ’s members under the infrastructure section of CEDIGAZ website.

This report includes three parts. Due to the exceptional events on the gas (and energy) scene in 2021, this year’s report includes an analysis of the main causes of the elevated European and North Asian spot gas prices (Part 1). Then, the report gives an assessment of UGS key metrics in 2020 and their evolution compared to 2019. The third part reviews major trends in UGS in selected key markets: Europe, Ukraine, Russia, USA, and China. In addition, recent UGS construction activity is reviewed in South and Central America and the Middle East.

The dramatic developments in gas markets in 2019-2020, with an acute oversupply situation due to the negative impact of the COVID-19 pandemic on demand and compounded by the massive increase of LNG supply from the US has stressed the fundamental importance of European Underground Gas Storage, assisted by Ukrainian UGS, to alleviate the imbalance of global gas markets. While until recently, UGS has mainly been developed in North America, Europe and the C.I.S., China is now on the fast lane for storage development. Russia, although the second global UGS capacity holder is still developing its storage infrastructure to serve both domestic and export markets.

This new report by CEDIGAZ provides an insightful review of storage activity in 4 key markets in 2020 and highlights the crucial role of UGS in balancing the global gas market as well as increasing security of gas supply in the context of rising geopolitical risks and trade tensions. The report also includes data on operating, under construction and planned facilities detailed by country.

Iran has one of the largest proven natural gas reserves in the world, hosts about 17% of the world’s proven natural gas reserves. Iran is also the world’s third–largest dry natural gas producer after the United States and Russia.

• At the end 2018, there were 662 underground gas storage (UGS) facilities in operation in the world. The global working gas capacity reached 421 bcm
• North America concentrates more than two thirds of the sites and accounts for almost 40% of global working gas capacity and half of global deliverability, the top five countries (United States, Russia, Ukraine, Canada and Germany) account for 70% of the worldwide capacities
• Storage in depleted fields dominate with 79% of global working gas volumes, but storage in salt caverns now accounts for 26% of global deliverability
• In 2018, the growth in gas storage capacity contrasted with the trends observed since 2015
• At worldwide level, there are 102 identified projects at different stages of planning
• UGS development activity is dominated by China, which alone accounts for almost half of the 37 bcm of working gas capacity under construction

At the end 2017, there were 671 underground gas storage facilities in operation in the world. The global working gas capacity has slightly increased to 417 bcm,up 0.4% from the end of 2016.

As of end 2016, there were 672 underground gas storage (UGS) facilities in operation in the world, representing a working gas capacity of 424 billion cubic meters (bcm), or 12% of 2016 world gas consumption. The number of storage facilities has decreased (680 UGS in 2015), mainly due to closure/mothballing of UGS in the United States and Europe. However, the global working capacity has slightly increased (+11 bcm) driven by expansions in the Commonwealth of Independent States (CIS), the Middle East and China. In Europe, storage capacity has continued its decline. Working gas capacity decreased by 5.8 bcm due to the closure of storage facilities in Germany, Ireland and the UK. The temporary closure of the Rough depleted field was confirmed as a permanent one in June 2017. This sharply reduces the UK storage capacity, and especially its seasonal storage capacity.

Since its first publication in 1990, "Underground Gas Storage in the World" has been the industry's reference on underground gas storage (UGS). The updated 2016 edition includes for the first time the coverage of LNG storage in the world. The report includes detailed analyses of the latest developments and trends in the storage industry, CEDIGAZ's Outlook to 2035 at regional and global levels, and extensive country analyses with complete datasets including current, under construction and planned UGS and LNG import facilities for 49 countries.
