TotalEnergies launches carbon sequestration project at Cameron LNG in Louisiana

TotalEnergies has signed an agreement with Sempra Infrastructure, Mitsui & Co., Ltd. and Mitsubishi Corporation for the development of the Hackberry Carbon Sequestration (HCS) project at Cameron LNG, a natural gas liquefaction and export facility located in southwest Louisiana, the company said on Monday.

The HCS project is primarily designed for capture, transportation, and storage of carbon dioxide (CO2) from Cameron LNG using acid gas removal units, dehydrated, compressed, and transported by pipeline about 10 km away, TotalEnergies said. The captured carbon will then be permanently stored in a saline aquifer using an injection well with a capacity of up to 2 million tons of CO2 per year.

“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,” Thomas Maurisse, Senior Vice President LNG at TotalEnergies, said in a statement.

“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,” he said.

In August 2021, the HCS project filed an application with the US Environmental Protection Agency (EPA) for the construction permit of such an injection well – the first application to be accepted by the EPA in Louisiana, the company said.

“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,” said Justin Bird, CEO of Sempra Infrastructure.

“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,” he added in a statement.
