Houston-area energy companies team up for initiative to produce electric natural gas

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.”

Houston-based Casimir has emerged from stealth with a $12 million seed round to commercialize its quantum energy chip.

The round was led by Austin-based Scout Ventures. Lavrock Ventures, Cottonwood Technology, Capital Factory, American Deep Tech, and Tim Draper of Draper Associates also participated in the round. The oversubscribed round exceeded the company’s original $8 million target, according to a news release.

Casimir’s semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company plans to commercialize its first-generation MicroSparc chip by 2028.

The MicroSparc chip measures 5 millimeters by 5 millimeters and is designed to produce 1.5 volts at 25 microamps, comparable to a small rechargeable battery, without degradation and no replacement cycle.

“Casimir represents exactly the kind of breakthrough dual-use technology Scout Ventures was built to back,” Brad Harrison, founder and managing partner at Scout Ventures, said in the release. “This is based on 100 years of science and we’re finally approaching a commercial product … We’re proud to lead this round and support Casimir’s journey from applied science to deployed technology.”

Casimir says it aims to scale its technology across the ”full power spectrum,” including large-scale energy systems that can power homes, commercial infrastructures and electric vehicles.

Casimir's scientific work has been supported by DARPA-funded nanofabrication research and its technology was incubated at the Limitless Space Institute (LSI). LSI is a nonprofit that works to innovate interstellar travel and was founded by Kam Ghaffarian. Technology investor and serial entrepreneur Ghaffarian has been behind companies like X-energy, Intuitive Machines, Axiom Space and Quantum Space.

Harold “Sonny” White, founder and CEO of Casimir, believes the technology can power devices for years without replacements.

“Millions of devices will operate for years without a battery ever needing to be replaced or recharged because we have engineered a customized Casimir cavity into hardware capable of producing persistent electrical power,” White added in the release. “I spent nearly two decades at NASA studying how we power humanity’s future. That work led me to the Casimir effect and the quantum vacuum, where new tools have allowed us to build on a century of scientific knowledge and bring abundant power to the world.”
