TotalEnergies, Sempra Infrastructure, Mitui and Mitsubishi are collaborating on a carbon capture project at Cameron LNG, which they said will be the first carbon dioxide injection well in the US state of Louisiana once accepted by the Environmental Protection Agency.

The Hackberry Carbon Sequestration (HCS) project filed an application in August 2021 with the EPA for the well’s construction.

As more companies are expected to file applications for Class VI CO2 injection wells, states are working to gain authority over approving the wells’ permits. North Dakota and Wyoming are the only states so far with primacy over Class VI wells, while Louisiana has submitted an application and Texas is preparing one.

Up to 2 million tonnes per annum of CO2 at the HCS project will be captured through gas removal units, dehydrated, compressed, and transported through pipelines to be stored in a saline aquifer.

“We are pleased to join forces 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,” said Thomas Maurisse, senior vice president LNG at TotalEnergies.

“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.”

Louisiana is a growing site for carbon capture projects, with agreements for at least 200,000 acres of pore space made in the last several months.

Companies such as Talos, Oxy Low Carbon Ventures, and Denbury have all made plans to develop the area for their respective CCS projects.

“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 Sempra Infrastructure chief executive Justin Bird.

“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”

The HCS project remains subject to necessary agreements, permits, and a final investment decision.
