Spring-based ExxonMobil, the country’s largest oil and gas company, might delay or cancel what would be the world’s largest low-carbon hydrogen plant due to a significant change in federal law. The project carries a $7 billion price tag.

The Biden-era Inflation Reduction Act created a new 10-year incentive, the 45V tax credit, for production of clean hydrogen. But under President Trump’s "One Big Beautiful Bill Act," the window for starting construction of low-carbon hydrogen projects that qualify for the tax credit has narrowed. The Inflation Reduction Act mandated that construction start by 2033. But the Big Beautiful Bill switched 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,” ExxonMobil Chairman and CEO Darren Woods said during the company’s recent second-quarter earnings call.

Woods said ExxonMobil is working to determine whether a combination of the 45Q tax credit for carbon capture projects and the revised 45V tax credit will help pave the way for a “broader” low-carbon hydrogen market.

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

“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.

Woods said ExxonMobil is trying to nail down sales contracts connected to the project, including exports of ammonia to Asia and Europe and sales of hydrogen in the U.S.

ExxonMobil announced in 2022 that it would build the low-carbon hydrogen plant at its refining and petrochemical complex in Baytown. The company has said the plant is slated to go online in 2027 and 2028.

As it stands now, ExxonMobil wants the Baytown plant to 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 company has said the project could store as much as 10 million metric tons of CO2 per year.

Mitsubishi, ExxonMobil announce low-carbon ammonia production partnership in Baytown

dream team

Spring-based ExxonMobil has teamed up with Japan’s Mitsubishi to potentially produce low-carbon ammonia and nearly carbon-free hydrogen at ExxonMobil’s facility in Baytown.

ExxonMobil and Mitsubishi are still working out details of the arrangement, such as equity participation in the project and use of the low-carbon ammonia.

“We look forward to furthering our leadership position, alongside Mitsubishi Corporation, to advance low-carbon hydrogen and ammonia globally, helping the world achieve a lower emission future,” Dan Ammann, president of ExxonMobil Low Carbon Solutions, says in a news release.

The ammonia would be shipped to Japan for power generation, process heating, and other industrial purposes. In conjunction with this project, Mitsubishi would convert part of a liquified petroleum gas (LPG) terminal into an ammonia terminal. The Japanese conglomerate plans to partner with Japanese petroleum company Idemitsu Kosan for ammonia purchases and a joint equity stake in the Baytown project.

The Baytown project is expected to generate as much as one billion cubic square feet of low-carbon hydrogen per day and more than one million tons of low-carbon ammonia per year.

A financial decision on the project is set for 2025, with the project coming online in 2029.

“We are excited to be closely collaborating with ExxonMobil to develop low-carbon hydrogen and ammonia supply chains that will bridge the United States and Japan,” says Masaru Saito, CEO of Mitsubishi’s Environmental Energy Group. “Together, we will lead this joint initiative to assist in the acceleration of the hard-to-abate sectors’ transition to clean energy.”

ExxonMobil’s low-carbon hydrogen project in Baytown adds Air Liquide as partner

team work

Spring-based energy giant ExxonMobil has enlisted Air Liquide as a partner for what’s being billed as the world’s largest low-carbon hydrogen project.

The deal will enable transportation of ExxonMobil’s low-carbon hydrogen through Air Liquide’s pipeline network. Furthermore, Air Liquide will build and operate four units to supply 9,000 metric tons of oxygen and up to 6,500 metric tons of nitrogen each day for the ExxonMobil project.

Air Liquide’s U.S. headquarters is in Houston.

ExxonMobil’s hydrogen production facility is planned for the company’s 3,400-acre Baytown refining and petrochemical complex. The project is expected to produce 1 billion cubic feet of low-carbon hydrogen daily from natural gas and more than 1 million tons of low-carbon ammonia annually while capturing more than 98 percent of the associated carbon emissions.

“Momentum continues to build for the world’s largest low-carbon hydrogen project and the emerging hydrogen market,” Dan Ammann, president of ExxonMobil Low Carbon Solutions, says in a news release.

The hydrogen project is expected to come online in 2027 or 2028.

ExxonMobil says using hydrogen to fuel its olefins plant at Baytown could reduce sitewide carbon emissions by as much as 30 percent. Meanwhile, the carbon capture and storage (CSUS) component of the project would be capable of storing 10 million metric tons of carbon each year, the company says.

Houston companies partner to advance industrial carbon capture tech

green team

Carbon Clean and Samsung E&A, both of which maintain their U.S. headquarters in Houston, have formed a partnership to accelerate the global use of industrial carbon capture systems.

Carbon Clean provides industrial carbon capture technology. Samsung E&A offers engineering, construction and procurement services. The companies say their partnership will speed up industrial decarbonization and make carbon capture more accessible for sectors that face challenges in decarbonizing their operations.

Carbon Clean says its fully modular columnless carbon capture unit, known as CycloneCC, is up to 50 percent smaller than traditional units and each "train" can capture up to 100,000 tonnes of CO2 per year.

“Our partnership with Samsung E&A marks a major milestone in scaling industrial carbon capture,” Aniruddha Sharma, chair and CEO of Carbon Clean, said in a news release.

Hong Namkoong, CEO of Samsung E&A, added that the partnership with Carbon Clean will accelerate the global rollout of carbon capture systems that “are efficient, reliable, and ready for the energy transition.”

Carbon Clean and Samsung E&A had previously worked together on carbon capture projects for Aramco, an oil and gas giant, and Modec, a supplier of floating production systems for offshore oil and gas facilities. Aramco’s Americas headquarters is also in Houston, as is Modec’s U.S. headquarters.

Major Houston energy companies join new Carbon Measures coalition

green team

Six companies with a large presence in the Houston area have joined a new coalition of companies pursuing a better way to track the carbon emissions of products they manufacture, purchase and finance.

Houston-area members of the Carbon Measures coalition are:

  • Spring-based ExxonMobil
  • Air Liquide, whose U.S. headquarters is in Houston
  • Mitsubishi Heavy Industries, whose U.S. headquarters is in Houston
  • Honeywell, whose Performance Materials and Technologies business is based in Houston.
  • BASF, whose global oilfield solutions business is based in Houston
  • Linde, whose Linde Engineering Americas business is based in Houston

Carbon Measures will create an accounting framework that eliminates double-counting of carbon pollution and attributes emissions to their sources, said Amy Brachio, the group’s CEO. The model is expected to take two years to develop, and between five and seven years to scale up, Bloomberg reported.

The coalition wants to create a system that will “unleash markets and competition,” unlock investments and speed up the pace of emissions reduction, said Brachio, former vice chair of sustainability at professional services firm EY.

“If you can’t measure it, you can’t manage it,” said Darren Woods, chairman and CEO of ExxonMobil. “The first step to reducing global emissions is to know where they’re coming from — and today, we don’t have an accurate system to do this.”

Other members of the coalition include BlackRock-owned Global Infrastructure Partners, Banco Satanader, EY and NextEra Energy.

“Transparent and consistent emissions accounting is not just a technical necessity — it’s a strategic imperative. It enables smarter decisions and accelerates real progress across industries and borders,” said Ken West, president and CEO of Honeywell Energy and Sustainability Solutions.

Wind and solar supplied over a third of ERCOT power, report shows

power report

Since 2023, wind and solar power have been the fastest-growing sources of electricity for the Electric Reliability Council of Texas (ERCOT) and increasingly are meeting stepped-up demand, according to a new report from the U.S. Energy Information Administration (EIA).

The report says utility-scale solar generated 50 percent more electricity for ERCOT in the first nine months this year compared with the same period in 2024. Meanwhile, electricity generated by wind power rose 4 percent in the first nine months of this year versus the same period in 2024.

Together, wind and solar supplied 36 percent of ERCOT’s electricity in the first nine months of 2025.

Heavier reliance on wind and solar power comes amid greater demand for ERCOT electricity. In the first nine months of 2025, ERCOT recorded the fastest growth in electricity demand (5 percent) among U.S. power grids compared with the same period last year, according to the report.

“ERCOT’s electricity demand is forecast to grow faster than that of any other grid operator in the United States through at least 2026,” the report says.

EIA forecasts demand for ERCOT electricity will climb 14 percent in the first nine months of 2026 compared with the same period this year. This anticipated jump coincides with a number of large data centers and cryptocurrency mining facilities coming online next year.

The ERCOT grid covers about 90 percent of Texas’ electrical load.
