A global independent energy and commodities group with its United States office in Houston has announced an investment in a Gulf Coast salt dome energy storage project.

Mercuria did not disclose its financial contribution into Lafayette, Louisiana-based Black Bayou Energy Hub LLC, but the company's support will go toward the development of the energy infrastructure of the large-scale, underground energy storage facility in Cameron and Calcasieu Parishes in Louisiana, which is alongside the Texas border.

"Mercuria's investment in Black Bayou Energy Hub represents a significant step towards enhancing the resilience and flexibility of our energy infrastructure. This partnership leverages Mercuria's robust financial capabilities and extensive expertise in commodity markets, aligning with Black Bayou's strategic location and development potential," Boris Bystrov, managing director of investments at Mercuria, says in a news release.

A new study from the University of Houston shows that there's no one-size-fits-all strategy for full vehicle electrification in America's largest U.S. cities.

The study by Ali Mousavinezhad and Yunsoo Choi considered changes in air pollution, specifically PM2.5 and ozone levels, in Houston, Los Angeles, New York and Chicago under different electrification scenarios and how the changes could impact public health.

“Our findings indicate vehicle electrification generally contributes to reducing greenhouse gas emissions, improving air quality, and lowering the mortality rate associated with exposure to toxic air pollutants,” Mousavinezhad says. Continue reading.

Houston clean fuels producer reaches milestone on South Texas hydrogen-powered refinery

Houston-based Element Fuels has completed the pre-construction phase of its hydrogen-powered clean fuels refinery and combined-cycle power plant in the Port of Brownsville.

Element Fuels, which has contracted with Houston-based McDermott to provide front-end engineering design services for the project, has designed the plant to produce and recycle hydrogen that will generate and deliver cleaner, higher-quality fuels, including much-needed high-octane gasoline and electricity for commercial and consumer consumption.

“Element Fuels has received the necessary permitting to construct and operate a refinery capable of producing in excess of 160,000 barrels, or approximately 6.7 million gallons, per day of finished gasoline, diesel, and jet fuel,” Founder and Co-CEO of Element Fuels John Calce says in a news release. “A permit for a greenfield refinery of this size, scope, and functionality has not been granted in the United States since the 1970s. This speaks to the innovative approaches we are taking to address climate and sustainability concerns in cleaner, greener ways that are new to the refinery space.” Continue reading.

Rice University's Liu Idea Lab for Innovation & Entrepreneurship, or Lilie, has named eight teams to the second cohort of the Lilie Summer Venture Studio, and two have sustainability as a goal.

According to Rice, the 12-week program received a record number of applications, that spanned the campus' degree offerings.

“We are thrilled to see such a high level of interest and excitement from Rice students for a high-growth venture accelerator,” Kyle Judah, executive director of Lilie, said in a statement. “The diversity and creativity in this year's applications were truly inspiring, and we’re excited to support these promising ventures with the resources and mentorship they need to hit escape velocity and create the next generation of pillar companies for Houston, Texas and the world.” Continue reading.

Texas hydrogen research hub brings on new corporate partner

A Texas US Department of Energy initiative has added a new corporate player.

Hitachi Energy has joined the DOE's H2@Scale in Texas and Beyond initiative with GTI Energy, Frontier Energy, The University of Texas Austin, and others. The initiative, which opened earlier this year, plans to assist in “integrating utility-scale renewable energy sources with power grids and managing and orchestrating a variety of energy sources” according to a news release.

Most of the H2@Scale project’s activities take place at University of Texas JJ Pickle Research Center in Austin. The project is part of a larger one to expand hydrogen’s role and help to decarbonize Texas. The H2@Scale project consists of multiple hydrogen production options like a vehicle refueling station alongside a fleet of hydrogen fuel cell vehicles. Continue reading.

A View From HETI

Texas fell four spots on WalletHub's annual Greenest States report. Photo via Pexels

Texas dropped in the rankings on WalletHub's Greenest States 2025 report.

The report, released last month, considered 28 relevant metrics—from air and water quality to the number of alternative fuel stations and green buildings per capita—to call out states doing the best (and worst) jobs of caring for the environment.

Texas came in at No. 42 out of 50, with a total score of 42.54 out of 100. Last year, the Lone Star State ranked No. 38 with a score of 50.40 based on 25 metrics.

Texas' poor ranking was driven by its last-placed ranking, coming in at No. 50, for overall environmental quality. It was tied for No. 45 for air quality and ranked No. 46 for water quality, which helped comprise the overall environmental quality score.

Other metrics fell closer toward the middle of the pack. The state ranked No. 32 for eco-friendly behaviors and No. 39 for climate-change contributions.

California also fell on the annual report. While the state claimed the top spot in 2024, it came in at No. 7 this year. Vermont, which came in second in 2024, was named the greenest state in 2025.

Hawaii, which didn't crack the top five last year, was ranked No. 2 on the 2025 report. New York, Maryland and Maine rounded out the top five this year.

West Virginia was the country's least green state again this year, followed by Louisiana, Kentucky, Alabama and Mississippi.

The report also showed that Democrat-led states ranked around No. 12 on average, whereas Republican states fell at around No. 33.

While the WalletHub report seems bleak for Texas, others have shown more positive signs for the state. Texas was ranked slightly above average in a recent ranking of the best states for sustainable development. A recently released U.S. Energy Storage Monitor shows that Texas led all states and surpassed California in the fourth quarter of 2024 by installing 1.2 gigawatts of utility-scale energy storage for solar and wind power.

Still, WalletHub also recently ranked Houston No. 98 out of 100 of the largest cities on its Greenest Cities in America report. Read more here.
