Venture Global LNG is planning to capture and sequester carbon at its Calcasieu Pass and Plaquemines LNG export projects in the US.

The company has already completed comprehensive engineering and geotechnical analysis for the carbon capture and sequestration (CCS) project.

Subject to regulatory approvals, the CCS project involves compressing CO₂ at its sites. The subsequent gas will then be transported for injecting deep into subsurface saline aquifers for permanent storage.

The aim is to capture and sequester about 500,000t of carbon per year from the two LNG export sites, through the project.

Venture Global CEO Mike Sabel said: “Through this historic carbon capture and sequestration project, we will build upon our existing state-of-the-art technology to develop even cleaner LNG at our facilities to displace coal around the world.

“Our location in Louisiana uniquely positions us to pioneer the deployment of this technology due to geology that can support industrial-scale injection and storage of CO₂.”

Additionally, Venture Global LNG intends to use similar infrastructure to capture and sequester 500,000t of CO₂ annually from the CP2 LNG facility.

Louisiana governor John Bel Edwards said: “I am pleased to learn that Venture Global LNG has identified significant opportunities for CO₂ capture and sequestration in Louisiana.

“Louisiana is well-positioned in terms of infrastructure, industry, geology and policy to take a leadership role in controlling and reducing atmospheric emissions of carbon through the use of carbon capture, utilisation and storage (CCUS) initiatives.”

Planned to be commissioned in 2022, the Calcasieu Pass project will have a nameplate capacity of ten million tonnes per annum (Mtpa).

The 20Mtpa Plaquemines LNG facility comprises a total of 18 liquefaction blocks and six pretreatment facilities.
