More than half-a-dozen energy companies — most with a significant presence in Houston — have signed up as founding members of a coalition focusing on the production of electric natural gas.

Founders of the e-NG Coalition are:

  • Engie, whose North American headquarters is in Houston
  • Mitsubishi, which operates a branch office in Houston
  • Osaka Gas, whose U.S. headquarters is in Houston
  • Sempra Infrastructure, which operates its Center of Excellence in Houston
  • TES (Tree Energy Solutions), whose U.S. headquarters is in Houston
  • Tokyo Gas, whose U.S. headquarters is in Houston
  • Toho Gas, a Japanese utility
  • TotalEnergies, whose U.S. headquarters is in Houston

Electric natural gas, also known as e-NG or e-natural gas, is a synthetic natural gas produced by combining renewable hydrogen and recycled CO2.

“The founding members of the coalition believe e-NG can provide a meaningful contribution to the energy transition by accelerating the development of renewable hydrogen,” the coalition says in a news release. “With large industrial capabilities and investment potential, the founding members are committed to the development of e-natural gas projects globally.”

TES spearheaded establishment of the e-NG Coalition.

“Collaboration is paramount to scaling up sustainable energy solutions and driving the energy transition forward. TES took the initiative to sponsor the creation of the e-NG Coalition and work together with leading industrial players to accelerate the development of e-NG,” says Marco Alverà, co-founder and CEO of TES.

Last September, Sempra Industries announced it had teamed up with four Japanese companies — Mitsubishi, Osaka Gas, Toho Gas, and Tokyo Gas — to explore building an e-natural gas project along the Gulf Coast.

The proposed project would generate 130,000 metric tons of e-natural gas per year. The gas would liquified at a terminal in Louisiana and then exported to Japan.

In a news release, the Japanese partners said they envisioned developing “the world’s first large-scale production and international supply chain of e-natural gas.”

A local subsidiary of a Japanese solar equipment manufacturer recently began producing solar modules at a new plant in Humble.

TOYO Co. Ltd.’s TOYO Solar LLC subsidiary can produce 1 gigawatt worth of solar modules per year at a 567,140-square-foot plant it leases in Lovett Industrial’s Nexus North Logistics Park on Greens Road. TOYO Solar’s next phase will accommodate 2.5 gigawatts’ worth of solar module manufacturing. The subsidiary eventually plans to expand manufacturing capacity to 6.5 gigawatts.

For now, TOYO Solar operates only one assembly line at the Humble plant. Once TOYO Solar has five assembly lines up and running, it could employ as many as 750 manufacturing workers there, according to Connect CRE.

TOYO says the plant enlarges its U.S. footprint “to be closer to the majority of its clients, meet the demand for American-made solar panels, and contribute to the growing demand for secure, sustainable energy solutions as demands on the grid continue to rise.”

Last month, TOYO purchased the remaining 24.99 percent stake in TOYO Solar to make it a wholly owned subsidiary. TOYO entered the Houston-area market through its 2024 acquisition of a majority stake in Solar Plus Technology Texas LLC.
