UGS - Underground Gas Storage

• 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.
