WGC2022 Countdown...


Dear Madam, Dear Sir,

welcome at the IGU Storage Committee Database portal. The data on UGS facilities were collected during 2015-2018 triennium and provide an overview of UGS status and its outlook. We would like to use this opportunity and thank to all gas companies and association which contributed with the data for this portal.

Storage provides general benefits for the entire gas infrastructure, not only for balancing of gas grids but it also helps the final customers to get their gas in efficient, reliable and secured way. The UGS Database SG has been established for the first time as a part of the International Gas Union Triennium work programme 2000-2003 as Basic Activity and since then, it provides valuable summary of UGS activities worldwide. The study has been constantly improved over trienniums and is complemented by below mentioned additional deliverables
After registration selected data are available; however, detailed data including their exports are available only to members of IGU Storage Committee and contributors.

About IGU

The International Gas Union (IGU) is a worldwide non-profit organisation. As per today, IGU has 91 charter members, 10 Premium Associate Members and 47 Associate Members in 91 countries.

About Storage Committee

The Storage Committee is a one of IGU Committees. It deals with Underground Gas Storage and is led by:
Chair Person: John W. Heer (USA),
Vice Chair: Ladislav Barkoci (Slovakia)

The work of WOC2 during the 2018-2021 triennium is supported by three study-groups:
  1. Study group SG2.1 (led by Ladislav Barkoci, Slovakia): Maintaining an active database on UGS in operation and UGS projects worldwide
  2. Study group SG2.2 (led by Amer ABDEL-HAQ, Germany): Defining best practices in UGS operations
  3. Study group SG2.3 (led by John W. Heer USA): Operating UGS in today's gas markets that includes support for renewable energy and grid balancing, the utilization of storage to reduce flaring and support of new LNG projects

About the World Gas Conference in Daegu

WGC 2021 will build on the IGU's 90-year history of engaging the foremost policy-makers, business leaders and technical experts to shape the global energy agenda while new commercial innovations and trends are demonstrated in a major trade exhibition open to all. Hosted by the Korea Gas Union in June 2021, the event aims to promote the role of natural gas in a sustainable future. WGC 2021 has strong support from the Korean Government, Daegu Metropolitan City, KOGAS and global gas industry leaders.
