(Reuters) – U.S. liquefied natural gas company Venture Global LNG on Thursday announced plans to capture and sequester carbon at its Calcasieu Pass and Plaquemines export plants in Louisiana.
This is part of a growing trend by energy companies to reduce greenhouse gas emissions to meet the growing demand from customers and governments for cleaner energy to reduce the damage caused by global warming.
Venture Global said in a statement that it is launching a carbon capture and sequestration (CCS) project that will compress carbon dioxide (CO2) at its sites and transport the gas for permanent storage in underground saline aquifers.
Venture Global estimated that it would capture and sequester around 500,000 tonnes of carbon per year from Calcasieu and Plaquemines.
In addition, the company plans to use a similar infrastructure to capture and sequester 500,000 tonnes of carbon per year from its proposed CP2 facility next to the Calcasieu site.
That million tonnes of carbon per year is the equivalent of taking nearly 200,000 cars off the road each year for 20 years, the company said.
The successful deployment of CCS at Calcasieu would be the first of its kind for an existing US LNG facility.
NextDecade Corp, another US LNG developer, has also said it wants to use CCS in its Rio Grande LNG export plant project in Texas. NextDecade has announced its intention to decide this year whether or not to build its plant.
Venture Global is building or developing more than 50 million tonnes per year (MTPA) of LNG production capacity in Louisiana, including the 10-MTPA Calcasieu, which is expected to cost around $ 4.5 billion and start producing LNG in test mode from the end of 2021.
The company also has several plants in different stages of development, including two 10-MTPA phases at Plaquemines, two 10-MTPA phases at Delta and two 10-MTPA phases at CP2.
