TotalEnergies signed an agreement on May 23 with Sempra Infrastructure, Mitsui & Co., Ltd. and Mitsubishi Corporation for the development of the first carbon capture and storage project produced by a natural gas liquefaction plant. The HCS (Hackberry Carbon Sequestration) project concerns the Cameron LNG production and export plant, a natural gas liquefaction and export plant located in Hackberry, southwestern Louisiana, USA, which has been operational since 2011.
HCS involves the capture of the carbon dioxide produced by the acid gas removal units, which is dehydrated, compressed and transported through pipes about 10 kilometers away. The CO2 will be permanently stored in a saline aquifer using an injection well with a capacity of up to 2 million tonnes of CO2 per year.
In August 2021, the HCS project was submitted to the United States Environmental Protection Agency (EPA) for the injection well construction permit, the first application accepted by the EPA in Louisiana. The project will be among the first carbon capture plants in North America, with the aim of establishing the gold standard for the safe and permanent storage of CO2.
“We are delighted to join forces with our partners to significantly reduce CO2 emissions at the Cameron LNG export terminal, thus enabling us to provide our customers with low-carbon LNG, a key fuel for the energy transition and a valuable resource. to diversify Europe’s energy supply, ”said Thomas Maurisse, TotalEnergies Senior Vice President LNG.
“We are excited to continue the development of the Hackberry Carbon Sequestration project, the first of Sempra Infrastructure’s zero net solutions projects, to help Cameron LNG produce cleaner LNG for its customers,” said Justin Bird, CEO of Sempra Infrastructure.
