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's clean hydrogen hub joins request to revise federal tax credit guidance

edits needed

The group of regional hubs tapped by the United States government to receive funding to develop clean hydrogen projects have banded together to request a revision of the U.S. Department of Treasury's proposed hydrogen production tax credit (45V) guidance.

Houston's HyVelocity Hub, which was selected to receive up to $1.2 billion from the government's initiative, has joined in on a joint letter with the other six H2Hubs asking for revised requirements. HyVelocity also submitted its own letter to the Treasury.

HyVelocity's letter asks for flexibility and certainty the implementation of the “three pillars” for electricity, which include temporality, incrementality, and deliverability.

"It is imperative that to enable the desired environmental, economic, and equity goals of the IRA, private investment in hydrogen production must advance at scale and at an accelerated pace. Hydrogen production project investments require stable market projections and assurance of regulatory stability to ensure the economics of the long-term projects. To support this investment environment, we recommend that projects be granted a 'grandfathered exemption' such that for the project's life, they can use the regulations in place at the time when construction begins," reads the letter from HyVelocity.

HyVelocity, representing the Gulf Coast region, plans to create up to 35,000 construction jobs and 10,000 permanent jobs across nine proposed core projects with a collective investment of more than $10 billion in private capital to bring low-carbon hydrogen to the market.

The Houston-area initiative is backed by industry partners AES Corporation, Air Liquide, Chevron, ExxonMobil, Mitsubishi Power Americas, Ørsted, and Sempra Infrastructure and The spearheaded by GTI Energy and other organizing participants, including the University of Texas at Austin, The Center for Houston’s Future, Houston Advanced Research Center, and around 90 other supporting partners from academia, industry, government, and beyond.

Sage Geosystems brings South Texas geothermal plant online

powering up

Houston-based Sage Geosystems, a provider of geothermal power, has begun full operations at its South Texas facility for the San Miguel Electric Cooperative.

Sage says the plant was recently “placed in service,” according to a news release. This means it’s fully built and tested, and ready to generate and supply electricity to the grid.

Since selling its first electricity in Q2 of this year, the facility has been operating for more than four months to evaluate aspects like efficiency and water management. Sage relied on its GeoTwin modeling tool to carry out some of the testing.

The testing demonstrates Sage’s proprietary approach to geothermal power “overcomes one of the industry’s most persistent challenges, high water losses in engineered reservoirs, while delivering the consistent performance required to scale next-generation geothermal,” co-founder and CEO Cindy Taff said in the release.

Sage says the South Texas facility will serve as a model for future projects, including one in Nevada. The Nevada facility will use Sage’s proprietary technology to extract geothermal heat from hot dry rock, creating a reliable, affordable source of carbon-free power.

During the testing period, water losses amounted to less than 10 percent. This low rate indicates most water remains in the system, enabling Sage to capture more usable energy, boost power production and improve the project’s finances, the company says.

“Commercial geothermal isn’t just about creating a reservoir. It’s about creating one whose performance can be engineered, predicted, and consistent,” Lev Ring, the company’s co-founder, president and chief technology officer, said in the release.

Since being founded in 2020, Sage has raised $159 million in outside funding. This includes a more than $97 million Series B round co-led by Ormat Technologies and Carbon Direct Capital.

Two years ago, Sage announced a deal with Meta Platforms, the parent company of Facebook and Instagram, to supply up to 150 megawatts of geothermal power to Meta data centers.

Halliburton Labs adds 3 energy, materials startups to Houston incubator

green team

Three new companies have joined Halliburton Labs, the incubator for early-stage energy and hardtech startups run by Houston energy giant Halliburton.

Halliburton Labs provides the emerging companies with mentorship, industry connections, laboratory access and other resources as they work toward commercialization. The latest companies to join the incubator focus on battery materials, resource recovery and gas separation solutions to address some of the "key bottlenecks in the energy and industrial landscape," according to a news release.

The new members include:

  • Electroflow, a California-based company that produces lithium iron phosphate (LFP) cathode material from lithium brines through its proprietary process. LFPs are critical components in batteries used in electric vehicles, grid storage systems and industrial electrification, according to Halliburton Labs.
  • Osmoses, a Cambridge, Massachusetts-based company that has developed a membrane platform to reduce the energy use, cost and emissions associated with gas separations used in natural gas, hydrogen, helium and other industrial applications
  • SiTration Inc., another Cambridge, Massachusetts-based company that has developed electro-extraction and filtration technologies to recover critical metals like copper directly from mining waste streams more quickly and affordably. Its process has completed successful pilot projects with Tier 1 mining companies in three continents.

"Affordable and reliable molecules are essential building blocks of the energy future. Each company brings a bold, technical solution to a complex industrial challenge. We look forward to helping them scale and deploy their technologies," Andres Cabada, Halliburton Labs managing director, added in the news release.

Halliburton Labs previously added four new members from around the world —Nandina REM, Noon Energy, Proof Energy and Tidal Metals—this spring. Alumni from the incubator include Houston-based companies like NanoTech Materials, which is developing insulation and fireproofing to reduce heat transfer in buildings and outdoor infrastructure; and SolvCor, which develops water additives to improve cooling for data centers and thermal storage.

With the addition of the three new members, the incubator currently supports nine early-stage companies.
