Carbon capture and sequestration technologies could soon be developed alongside Louisiana’s Cameron LNG, a natural gas liquefaction and export facility located in the southwest of the US state.

TotalEnergies, Sempra Infrastructure, Mitsui and Mitsubishi Corporation on Wednesday (24th May) unveiled such plans to capture, transport and storage carbon dioxide (CO2) as a means of decarbonisation.

Under project plans, CO2 from the LNG site will be captured by acid gas removal units, dehydrated, compressed and transported by a pipeline approximately 10 kilometres away.

Once transported, the CO2 will be permanently stored in a saline aquifer using an injection well with a capacity of up to two million tonnes of CO2 annually.

Thomas Maurisse, Senior Vice-President of LNG at TotalEnergies, said, “We are pleased to join force with our partners to significantly reduce CO2 emissions at Cameron LNG export terminal, thus enabling us to supply our customers with low-carbon LNG, a key fuel for the energy transition and a valuable asset for diversifying Europe’s energy supply.”

“This project, aiming at reducing greenhouse gas emissions associated with the LNG value chain, is a concrete illustration of TotalEnergies’ sustainability and climate strategy implementation.”

TotalEnergies, Sempra Infrastructure, Mitsui and Mitsubishi Corporation have called the joint effort the Hackberry Carbon Sequestration (HCS) project.

Justin Bird, CEO of Sempra Infrastructure, added, “We are excited to advance the development of the Hackberry Carbon Sequestration project, the first of Sempra Infrastructure’s net zero solutions projects, to help Cameron LNG produce cleaner LNG for its customers.”

“This project is expected to be among the first North America carbon capture facilities designed to receive and store CO2 from multiple sources, and our goal is for this facility to set the gold standard for safe and permanent CO2 storage.”
