US firm Venture Global LNG has revealed plans to capture and sequester carbon at its Calcasieu Pass and Plaquemines LNG export facilities in Louisiana.
Having concluded engineering and geotechnical analysis, the company aims to launch, subject only to regulatory approvals, a shovel-ready carbon capture and sequestration (CCS) project, it said on Thursday.
The project would compress CO2 at its sites and then transport and inject it deep into subsurface saline aquifers where it will be permanently stored.
Venture Global would capture and sequester an estimated 500,000 tons of carbon per year from its Calcasieu Pass and Plaquemines liquefaction sites, it said.
In addition, the company plans to use similar infrastructure to capture and sequester 500,000 tons of carbon per year from the CP2 LNG facility once permitted.
Altogether, Venture Global aims to sequester 1 million tons of carbon per year, the equivalent of removing nearly 200,000 cars off the road each year for 20 years, it said.
The deployment of carbon capture and sequestration technology at Calcasieu Pass would be the first of its kind for an existing LNG facility in the United States, the firm said.
Venture Global has set out out plans to develop over 50 mtpa of LNG production capacity in Louisiana.
The Calcasieu Pass project will produce about 10 mtpa of LNG from 18 modular units configured in 9 blocks while the Plaquemines project would have a 20 mtpa capacity at full buildout.
