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.

Houston maritime startup raises $43M to electrify cargo vessels

A Houston-based maritime technology company that is working to reduce emissions in the cargo and shipping industry has raised VC funding and opened a new Houston headquarters.

Fleetzero announced that it closed a $43 million Series A financing round this month led by Obvious Ventures with participation from Maersk Growth, Breakthrough Energy Ventures, 8090 Industries, Y Combinator, Shorewind, Benson Capital and others. The funding will go toward expanding manufacturing of its Leviathan hybrid and electric marine propulsion system, according to a news release.

The technology is optimized for high-energy and zero-emission operation of large vessels. It uses EV technology but is built for maritime environments and can be used on new or existing ships with hybrid or all-electric functions, according to Fleetzero's website. The propulsion system was retrofitted and tested on Fleetzero’s test ship, the Pacific Joule, and has been deployed globally on commercial vessels.

Fleetzero is also developing unmanned cargo vessel technology.

"Fleetzero is making robotic ships a reality today. The team is moving us from dirty, dangerous, and expensive to clean, safe, and cost-effective. It's like watching the future today," Andrew Beebe, managing director at Obvious Ventures, said in the news release. "We backed the team because they are mariners and engineers, know the industry deeply, and are scaling with real ships and customers, not just renderings."

Fleetzero also announced that it has opened a new manufacturing and research and development facility, which will serve as the company's new headquarters. The facility features a marine robotics and autonomy lab, a marine propulsion R&D center and a production line with a capacity of 300 megawatt-hours per year. The company reports that it plans to increase production to three gigawatt-hours per year over the next five years.

"Houston has the people who know how to build and operate big hardware–ships, rigs, refineries and power systems," Mike Carter, co-founder and COO of Fleetzero, added in the release. "We're pairing that industrial DNA with modern batteries, autonomy, and software to bring back shipbuilding to the U.S."

Shell partners with UK-based co. for hydrogen electrolyzer pilot

ultra-efficient electrolyzer

Shell Global Solutions International, a subsidiary of Shell, which maintains its U.S. headquarters in Houston, has signed a collaboration agreement with London-based Supercritical Solutions to advance Supercritical’s ultra-efficient hydrogen electrolyzer technology toward a field pilot demonstration.

In the deal, the companies will collaborate on a paid technology feasibility study that will support the evaluation and planning of the pilot demonstration, according to a news release. Supercritical Solutions’ technology aims to deliver high-efficiency renewable hydrogen at a lower cost for the industrial hydrogen market.

"Signing this collaboration agreement with Shell is a major milestone for Supercritical Solutions and an important step on our commercialisation journey,” Luke Tan, co-founder of Supercritical, said in the news release. “We are directly addressing the cost and complexity barriers facing the renewable hydrogen market. We are excited to move forward with a company like Shell, whose global leadership has been proven to accelerate innovative technologies to market.”

Supercritical’s hydrogen electrolyser technology can operate at high temperatures and pressures of up to 220 bar without the need for an external hydrogen compressor, rare-earth materials or easily degradable membranes. The technology removes the typical compression step in the process while delivering hydrogen at industry standards. It requires significantly less energy than many traditional electrolyzers and is more cost-efficient.

This recent investment builds on an ongoing relationship between Shell and Supercritical. Supercritical was founded in 2020 and was runner-up in Shell’s New Energy Challenge, which helps startups and scaleups develop sustainable technologies, in 2021. Shell Ventures then invested in Supercritical’s Series A funding round in 2024 with Toyota Ventures.

3 Houston-area companies named to Global Cleantech 100

Energized

Three Houston-area companies—Amperon, Hertha Metals and Vaulted Deep—appear on this year’s Global Cleantech 100 list.

The unranked list, generated by market intelligence and advisory firm Cleantech Group, identifies the 100 privately held companies around the world that are most likely to make a significant impact in the cleantech market over the next five to 10 years.

For the 2026 list, Cleantech Group received more than 24,000 Global Cleantech 100 nominations from nearly 60 countries. Cleantech Group scored those companies and narrowed the contenders to 264. An expert panel reviewed those nominees, and the list was whittled down to the 100 winners.

Here’s a rundown of the three Houston-area honorees:

Amperon

Founded in 2018 by Sean Kelly and Abe Stanway, Houston-based Amperon offers an AI-enabled energy forecasting and analytics platform designed to help stabilize electric grids. Amperon received undisclosed amounts of venture capital from National Grid Partners and Tokyo Gas Co. Ltd. last year and announced a recent investment from Samsung Ventures earlier this month.

Hertha Metals

Founded in 2022 by Laureen Meroueh, Conroe-based Hertha Metals provides a single-step process for producing sustainable steel. Last year, the company emerged from stealth mode and raised more than $17 million in venture capital.

Vaulted Deep

Vaulted Deep’s technology injects excess organic waste underground to remove carbon dioxide from the atmosphere. Julia Reichelstein and Omar Abou-Sayed founded the Houston-based company in 2023. Last year, the startup raised $32.3 million in venture capital. Also in 2025, Vaulted Deep signed a 12-year deal with software giant Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.

Vaulted Deep also made the list last year, along with Houston-based Syzygy Plasmonics and Fervo Energy. Fervo was also named the 2025 North American Company of the Year by Cleantech Group.
