Commonwealth LNG partners with OnStream CO2 for CCS solution

US LNG developer Commonwealth LNG November 28 announced a partnership with OnStream CO₂ to implement a carbon capture and storage (CCS) solution at its 9.3mn tonnes/year LNG facility currently under development in Cameron Parish, Louisiana.

Under the agreement, OnStream CO₂, a joint venture between Carbonvert and Castex Carbon Solutions, will design, construct, own, and operate CO₂ capture equipment near the Commonwealth LNG site. The captured CO₂ will be permanently sequestered at the Cameron Parish CO₂ hub. Commonwealth LNG will dedicate CO₂ emitted from the LNG facility for a 20-year term.

“Adding carbon capture technology complements our comprehensive goal of achieving best-in-class environmental standards through measures that also include a focus on responsibly sourced gas and the installation of the highest efficiency gas turbines,” said Commonwealth LNG CEO Paul Varello.

The Carbonvert-Castex joint venture recently secured an operating agreement with the State of Louisiana to develop a 24,000-acre tract of land offshore Cameron Parish, where it will permanently store CO₂ in a hub with capacity for more than 250mn tonnes. Castex will serve as the operator for the Cameron Parish CO₂ hub.

Commonwealth LNG anticipates a final investment decision on its LNG project in the first half of 2024, with first cargo deliveries expected in 2027.
