Snohvit

Equinor’s Snøhvit CCS project is an offshore carbon storage operation integrated with the Snøhvit LNG development in the Barents Sea. Since 2008, CO₂ separated from natural gas at the Melkøya LNG plant near Hammerfest has been captured and transported offshore for permanent injection into a deep saline formation beneath the Snøhvit field. The project was one of the world’s first full-scale CCS deployments in the natural gas and LNG sector and demonstrated long-term geological storage of CO₂ at industrial scale. Captured CO₂ is injected into the Tubåen and later the Stø formations at depths of approximately 2,600 meters, providing secure long-term storage while reducing emissions from LNG production. The Snøhvit CCS operation forms a key part of Norway’s offshore carbon management experience and continues to inform the design and operation of newer CCS projects in the North Sea and Arctic regions.
