An oil and gas exploration and production company has signed on to collaborate on a green hydrogen project in Texas to keep up with growing global market demand.

INPEX Corp. and Green Hydrogen International have agreed to a Joint Study Agreement to advance a South Texas hydrogen production facility called "Hydrogen City." The project's first phase will produce 280,000 tons per year of green hydrogen and 1 million tons per year of green ammonia. Construction is slated to begin in 2026 with commercial operation expected in 2029.

INPEX's "unparalleled expertise in large energy project development combined with a world-class marketing organization will provide enormous advantages to the Hydrogen City project and our goal of producing the world's lowest-cost green hydrogen by 2029," Brian Maxwell, CEO of GHI, says in a news release.

The partnership brings together both entities' expertise, with INPEX's experience developing large scale energy projects and marketing LNG to international customers. Meanwhile, GHI uses salt cavern storage and behind-the-meter renewable power to produce low-cost green hydrogen.

"I am excited to announce this green hydrogen project in Texas, which exemplifies our unwavering commitment to environmental leadership and innovation," INPEX Representative Director, President, and CEO Takayuki Ueda says in the release. "INPEX's dedication to a brighter, greener future remains steadfast, and this endeavor in Texas marks a pivotal step in our vision for a more sustainable tomorrow."

INPEX is also a part of a large-scale, low-carbon ammonia production and export project on the Houston Ship Channel that was anounced ealier this month.

Hydrogen City, located in South Texas atop the Peidras Pintas Salt Dome, was originally announced in March 2022. There will be a 75 mile pipeline from Hydrogen City to Corpus Christi, supplying a 1 Million Tonne Per Annum (MTPA) ammonia production facility and local off-takers.

ExxonMobil pauses plans for $7B hydrogen plant in Baytown

project on pause

As anticipated, Spring-based oil and gas giant ExxonMobil has paused plans to build a low-hydrogen plant in Baytown, Chairman and CEO Darren Woods told Reuters.

“The suspension of the project, which had already experienced delays, reflects a wider slowdown in efforts by traditional oil and gas firms to transition to cleaner energy sources as many of the initiatives struggle to turn a profit,” Reuters reported.

Woods signaled during ExxonMobil’s second-quarter earnings call that the company was weighing whether it would move forward with the proposed $7 billion plant.

The Biden-era Inflation Reduction Act established a 10-year incentive, the 45V tax credit, for production of clean hydrogen. But under President Trump’s One Big Beautiful Bill Act, the period for beginning construction of low-carbon hydrogen projects that qualify for the tax credit has been compressed. The Inflation Reduction Act called for construction to begin by 2033. The Big Beautiful Bill changed the construction start time to early 2028.

“While our project can meet this timeline, we’re concerned about the development of a broader market, which is critical to transition from government incentives,” Woods said during the earnings call.

Woods had said ExxonMobil was figuring out whether a combination of the 45Q tax credit for carbon capture projects and the revised 45V tax credit would enable a broader market for low-carbon hydrogen.

“If we can’t see an eventual path to a market-driven business, we won’t move forward with the [Baytown] project,” Woods told Wall Street analysts.

“We knew that helping to establish a brand-new product and a brand-new market initially driven by government policy would not be easy or advance in a straight line,” he added.

ExxonMobil announced in 2022 that it would build the low-carbon hydrogen plant at its refining and petrochemical complex in Baytown. The company had indicated the plant would start initial production in 2027.

ExxonMobil had said the Baytown plant would produce up to 1 billion cubic feet of hydrogen per day made from natural gas, and capture and store more than 98 percent of the associated carbon dioxide. The plant would have been capable of storing as much as 10 million metric tons of CO2 per year.

Greentown and partners name 10 startups to carbontech accelerator

CenterPoint gets go-ahead for $2.9B upgrade of Houston grid

grid resiliency

Texas utility regulators have given the green light for Houston-based CenterPoint Energy to spend $2.9 billion on strengthening its Houston-area electric grid to better withstand extreme weather.

The cost of the plan is nearly $3 billion below what CenterPoint initially proposed to the Public Utility Commission of Texas.

In early 2025, CenterPoint unveiled a $5.75 billion plan to upgrade its Houston-area power system from 2026 through 2028. But the price tag dropped to $2.9 billion as part of a legal settlement between CenterPoint and cities in the utility’s service area.

Sometime after the first quarter of next year, CenterPoint customers in the Houston area will pay an extra $1 a month for the next three years to cover costs of the resiliency plan. CenterPoint serves 2.9 million customers in a 12-county territory anchored by Houston.

CenterPoint says the plan is part of its “commitment to building the most resilient coastal grid in the country.”

A key to improving CenterPoint’s local grid will be stepping up management of high-risk vegetation (namely trees), which ranks as the leading cause of power outages in the Houston area. CenterPoint says it will “go above and beyond standard vegetation management by implementing an industry-leading three-year trim cycle,” clearing vegetation from thousands of miles of power lines.

The utility company says its plan aims to prevent Houston-area power outages in case of hurricanes, floods, extreme temperatures, tornadoes, wildfires, winter storms, and other extreme weather events.

CenterPoint says the plan will:

  • Improve systemwide resilience by 30 percent
  • Expand the grid’s power-generating capacity. The company expects power demand in the Houston area to grow 2 percent per year for the foreseeable future.
  • Save about $50 million per year on storm cleanup costs
  • Avoid outages for more than 500,000 customers in the event of a disaster like last year’s Hurricane Beryl
  • Provide 130,000 stronger, more storm-resilient utility poles
  • Put more than 50 percent of the power system underground
  • Rebuild or upgrade more than 2,200 transmission towers
  • Modernize 34,500 spans of underground cables

In the Energy Capital of the World, residents “expect and deserve an electric system that is safe, reliable, cost-effective, and resilient when they need it most. We’re determined to deliver just that,” Jason Wells, president and CEO of CenterPoint, said in January.
