DOE proposes cutting $1.2 billion in funding for hydrogen hub

funding cuts

The U.S. Department of Energy has proposed cutting $1.2 billion in funding for the HyVelocity Gulf Coast Hydrogen Hub, a clean energy project backed by AES, Air Liquide, Chevron, ExxonMobil, Mitsubishi Power Americas and Ørsted.

The HyVelocity project, which would produce clean hydrogen, appears on a new list of proposed DOE funding cancellations. The list was obtained by Latitude Media.

As of November, HyVelocity had already received $22 million of the potential $1.2 billion in DOE funding.

Other than the six main corporate backers, supporters of HyVelocity include the Center for Houston’s Future, Houston Advanced Research Center, Port Houston, University of Texas at Austin, Shell, the Texas governor’s office, Texas congressional delegation, and the City of Fort Worth.

Kristine Cone, a spokeswoman for GTI Energy, the hub’s administrator, told EnergyCapital that it hadn’t gotten an update from DOE about the hub’s status.

The list also shows the Magnolia Sequestration Hub in Louisiana, being developed by Occidental Petroleum subsidiary 1PointFive, could lose nearly $19.8 million in federal funding and the subsidiary’s South Texas Direct Air Capture (DAC) Hub on the King Ranch in Kleberg County could lose $50 million. In September, 1Point5 announced the $50 million award for its South Texas hub would be the first installment of up to $500 million in federal funding for the project.

Other possible DOE funding losses for Houston-area companies on the list include:

  • A little over $100 million earmarked for Houston-based BP Carbon Solutions to develop carbon storage projects
  • $100 million earmarked for Dow to produce battery-grade solvents for lithium-ion batteries. Dow operates chemical plants in Deer Park and LaPorte
  • $39 million earmarked for Daikin Comfort Technologies North America to produce energy-efficient heat pumps. The HVAC company operates the Daikin Texas Technology Park in Waller
  • Nearly $6 million earmarked for Houston-based Baker Hughes Energy Transition to reduce methane emissions from flares
  • $3 million earmarked for Spring-based Chevron to explore development of a DAC hub in Northern California
  • Nearly $2.9 million earmarked for Houston-based geothermal energy startup Fervo Energy’s geothermal plant in Utah

Houston ranks No. 99 out of 100 on new report of greenest U.S. cities

Sustainability Slide

Houstonians may be feeling blue about a new ranking of the greenest cities in the U.S.

Among the country’s 100 largest cities based on population, Houston ranks 99th across 28 key indicators of “green” living in a new study from personal finance website WalletHub. The only city with a lower ranking is Glendale, Arizona. Last year, Houston landed at No. 98 on the WalletHub list.

“‘Green’ living means a choice to engage in cleaner, more sustainable habits in order to preserve the planet as much as possible,” WalletHub says.

Among the study’s ranking factors are the amount of greenhouse gas emissions per capita, the number of “smart energy” policies, and the presence of “green job” programs.

In the study, Houston received an overall score of 35.64 out of 100. WalletHub put its findings into four buckets, with Houston ranked 100th in the environment and transportation categories, 56th in the lifestyle and policy category, and 52nd in the energy sources category.

In the environment category, Houston has two big strikes against it. The metro area ranks among the 10 worst places for ozone pollution (No. 7) and year-round particle pollution (No. 8), according to the American Lung Association’s 2025 list of the most polluted cities.

In the WalletHub study, San Jose, California, earns the honor of being the country’s greenest city. It’s followed by Washington, D.C.; Oakland, California; Irvine, California; and San Francisco.

“There are plenty of things that individuals can do to adopt a green lifestyle, from recycling to sharing rides to installing solar panels on their homes,” WalletHub analyst Chip Lupo said in the report. “However, living in one of the greenest cities can make it even easier to care for the environment, due to sustainable laws and policies, access to locally grown produce, and infrastructure that allows residents to use vehicles less often. The greenest cities also are better for your health due to superior air and water quality.”
