The DOE is set to contribute 192.3 million euro, following an earlier 10.22 million euro provided for preliminary design. The estimated total cost of the project is 320 million euro. The project is set to transport the CO₂ via pipelines to the West Hastings oil field and use it in Enhanced Oil Recovery (EOR). A Monitoring, Verification and Accounting programme run by West Hastings is to provide accounting of the aimed 1 million tonnes of CO₂ to be stored.

Site preparations at Lake Charles began in 2010 and construction of the gasification plant is expected to begin in the first quarter of this year and be completed within three years. The gasification plant uses petroleum coke as feedstock, converting it to syngas. ‘Petcoke’ is a solid by-product of oil refining, similar to coal and is therefore co-fired in power plants with coal. While not directly involving coal, the Lake Charles CCS project is considered a test for technologies that could be used to capture CO2 from coal-fired power plants. According to a Penn Energy article, other elements of the project include two Lurgi Rectisol Acid Gas Removal (AGR) units and two compressors to pressurize the CO₂ for transport and storage, as well as a pipeline to carry the CO₂ nearly 12 miles to connect to the existing Green Pipeline, which extends across Louisiana into Texas.
