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.

As you might have seen, Baker Hughes had two pieces of news last week.

Houston-based energy technology company Baker Hughes is rolling out two new products — pressure sensors for the hydrogen sector.

“Hydrogen plays a key role in the transition to a more sustainable, lower-emissions future but also poses challenges for infrastructure and equipment due to hydrogen embrittlement,” Gordon Docherty says. Read more.

Additionally, the Baker Hughes Foundation revealed details on a $75,000 grant to Houston Minority Supplier Development Council, or HMSDC, and a $100,000 grant to Washington, D.C.-based WEConnect International. HMSDC supports economic growth of minority-owned businesses, and WEConnect International is focused on women-owned companies. Read more.

Houston scientists develop 'recharge-to-recycle' reactor for lithium-ion batteries

reduce, recharge, recycle

Engineers at Rice University have developed a cleaner, innovative process to turn end-of-life lithium-ion battery waste into new lithium feedstock.

The findings, recently published in the journal Joule, demonstrate how the team’s new “recharge-to-recycle” reactor recharges the battery’s waste cathode materials to coax out lithium ions into water. The team was then able to form high-purity lithium hydroxide, which was clean enough to feed directly back into battery manufacturing.

The study has major implications for the electric vehicle sector, which significantly contributes to the waste stream from end-of-life battery packs. Additionally, lithium tends to be expensive to mine and refine, and current recycling methods are energy- and chemical-intensive.

“Directly producing high-purity lithium hydroxide shortens the path back into new batteries,” Haotian Wang, associate professor of chemical and biomolecular engineering, co-corresponding author of the study and co-founder of Solidec, said in a news release. “That means fewer processing steps, lower waste and a more resilient supply chain.”

Sibani Lisa Biswal, chair of Rice’s Department of Chemical and Biomolecular Engineering and the William M. McCardell Professor in Chemical Engineering, also served as co-corresponding author on the study.

“We asked a basic question: If charging a battery pulls lithium out of a cathode, why not use that same reaction to recycle?” Biswal added in the release. “By pairing that chemistry with a compact electrochemical reactor, we can separate lithium cleanly and produce the exact salt manufacturers want.”

The new process also showed scalability, according to Rice. The engineers scaled the device to 20 square centimeters, then ran a 1,000-hour stability test and processed 57 grams of industrial black mass supplied by industry partner Houston-based TotalEnergies. The results produced lithium hydroxide that was more than 99 percent pure. It also maintained an average lithium recovery rate of nearly 90 percent over the 1,000-hour test, showing its durability. The process also worked across multiple battery chemistries, including lithium iron phosphate, lithium manganese oxide and nickel-manganese-cobalt variants.

Looking ahead, the team plans to scale the process and consider ways it can sustain high efficiency for greater lithium hydroxide concentrations.

“We’ve made lithium extraction cleaner and simpler,” Biswal added in the release. “Now we see the next bottleneck clearly. Tackle concentration, and you unlock even better sustainability.
