It has the same molecular composition as conventional natural gas, allowing it to be transported and stored using existing infrastructure. 

The new e-NG Coalition consists of Engie, Mitsubishi Corporation, Osaka Gas, Sempra Infrastructure, Toho Gas, Tokyo Gas, TotalEnergies and Tree Energy Solutions (TES).  

These companies are combining their expertise to support the development of e-NG in a reliable, affordable and sustainable manner.  

The coalition will focus on promoting e-NG use, fostering a global market, and supporting policy development and standardisation. 

Currently, TotalEnergies is involved in the Live Oak e-NG project with TES in the US, aiming to produce between 100,000 and 200,000 tonnes of e-NG annually by 2030.  

TotalEnergies president of gas, renewables & power Stéphane Michel said: ”As a major player in LNG and renewable electricity, and as e-NG pioneers thanks to our Live Oak project, it is important for us to contribute to the establishment of a global coalition for the development of e-NG.  

“This synthetic fuel will contribute to the energy transition by facilitating the decarbonisation of certain industrial activities, particularly those that are difficult to electrify, while making use of existing downstream infrastructures.”  

Separately, TotalEnergies has signed an agreement to acquire Talos Low Carbon Solutions, a US company specialising in carbon capture and storage.  

The deal will give TotalEnergies a 25% stake in the Bayou Bend project and interests in other regional projects. 

TotalEnergies chairman and CEO Patrick Pouyanné said: “TotalEnergies is pleased to enter the Bayou Bend project through the acquisition of Talos Low Carbon Solutions. Ideally located close to our Port Arthur refinery and our petrochemicals assets in La Porte, this project will be instrumental for the reduction of direct emissions from our US operations.  

“This transaction gives momentum to the decarbonisation of hard-to-abate US emissions and marks a milestone on our journey to get to net zero by 2050, together with society.”
