Repsol, Crescent Midstream part of offshore Louisiana CCS partnership

Repsol SA, Crescent Midstream LLC, Cox Operating LLC, and Carbon Zero US LLC earlier this month formed a partnership to develop a hub offshore Grand Isle, La., for permanent carbon dioxide (CO₂) storage. The carbon capture and sequestration (CCS) project will repurpose Cox offshore infrastructure, currently consisting of more than 600 wells in 66 fields.

Crescent Midstream has completed initial front-end engineering and design for a 110-mile CO₂ pipeline from Geismar, La., to Grand Isle, using existing Crescent pipeline rights-of-way.

In conjunction with its partners in the CCS hub, Carbon Zero recently applied to the US Department of Energy’s CarbonSAFE program for a spot in one of its proposed carbon dioxide sequestration pilots.

The companies describe the project as one of the Gulf of Mexico’s largest CCS developments.
