Houston just made a list that no one wants it to be on.
Data compiled by the National Public Utilities Council ranks Houston as the 15th most polluted city in the U.S. No other Texas city appears in the ranking. Three California cities — Bakersfield, Visalia, and Fresno — took the top three spots.
The ranking considers a city’s average volume of fine particulate matter in the air per year. Fine particulate matter (formally known as PM2.5) includes soot, soil dust, and sulphates.
The council based its ranking on the average annual concentration of PM2.5 as measured in micrograms per cubic meter of air, known as µg/m3. The ranking lists Houston’s average annual µg/m3 as 11.4. The World Health Organization (WHO) recommends a top µg/m3 of 5, while the American Lung Association sets 9 µg/m as an average annual guideline.
A report released in 2024 by Smart Survey found that the Houston area had just 38 days of good air quality the previous year.
“Most of Houston’s air pollution comes from industrial sources and diesel engines, although sources as diverse as school buses and meat cooking also contribute to … the problem,” the nonprofit Air Alliance Houston says.
The U.S. Environmental Protection Agency says PM2.5 poses “the greatest risk to health” of any particulate matter. Among other health issues, fine particulate matter contributes to cardiovascular disease, lung cancer, and chronic pulmonary disease.
Among the sources of PM2.5 are wildfires, wood-burning stoves, and coal-fired plants, according to the American Lung Association.
The WHO says air pollution causes 7 million deaths annually and may cost the global economy $18 trillion to 25 trillion by 2060. With 70 percent of the population expected to live in urban centers by mid-century, cities are at the forefront of efforts to reduce pollution, according to National Public Utilities Council.

D.C. energy company secures $233M for ERCOT battery storage projects
fresh funding
The Electricity Reliability Council of Texas’ grid will get a boost courtesy of Lydian Energy.
The D.C.-based company announced the successful financial close of its first institutional project financing totaling $233 million, backed by ING Group and KeyBank. The financing will support three battery energy storage system (BESS) projects in Texas.
Lydian is an independent power producer that specializes in the development, construction and operation of utility-scale solar and battery energy storage projects. The company reports that it plans to add 550 megawatts of energy—which can power approximately 412,500 homes—to the Texas grid administered by ERCOT.
“This financing marks an important step forward as we continue executing on our vision to scale transformative battery storage projects that meet the evolving energy needs of the communities we serve,” Emre Ersenkal, CEO at Lydian Energy, said in a news release.
The projects include:
Pintail
- Located in San Patricio county
- 200 megawatts
- Backed by ING
Crane
- Located in Crane county
- 200 megawatts
- Backed by ING
Headcamp
- Located in Pecos county
- 150 megawatts
- Backed by KeyBank
ING served as the lender for Pintail and Crane projects valued at a combined total of approximately $139 million.
KeyBank provided a $94 million financing package for the Headcamp project. KeyBanc Capital Markets also structured the financing package for Headcamp.
The three projects are being developed under Excelsior Energy Capital’s Fund II. Lydian’s current portfolio comprises 20 solar and storage projects, totaling 4.7 gigawatts of capacity.
“Our support of Lydian’s portfolio reflects ING’s focus on identifying strategic funding opportunities that align with the accelerating demand for sustainable power,” Sven Wellock, managing director and head of energy–renewables and power at ING, said in the release. “Battery storage plays a central role in supporting grid resilience, and we’re pleased to back a platform with strong fundamentals and a clear execution path.”
The facilities are expected to be placed in service by Q4 2025. Lydian is also pursuing additional financing for further projects, which are expected to commence construction by the end of 2025.
“These financings represent more than capital – they reflect the strong demand for reliable energy infrastructure in high-growth U.S. markets,” Anne Marie Denman, co-founding partner at Excelsior Energy Capital and chair of the board at Lydian Energy, added in the news release. “We’re proud to stand behind Lydian’s talented team as they deliver on the promise of battery storage with bankable projects, proven partners, and disciplined execution. In the midst of a lot of noise, these financings are a reminder that capital flows where infrastructure is satisfying fundamental needs of our society – in this case, the need for reliable, sustainable, domestic, and affordable energy.”
Houston American Energy closes acquisition of New York low-carbon fuel co.
power deal
Renewable energy company Houston American Energy Corp. (NYSE: HUSA) has acquired Abundia Global Impact Group, according to a news release.
Houston American reports that the acquisition will allow it to create a combined company focused on converting waste plastics into high-value, drop-in, low-carbon fuels and chemical products. It plans to move forward with Abundia’s plans for developing large-scale recycling projects, with a new facility previously announced for the Gulf Coast, located in Cedar Port Industrial Park, near the Baytown area of Houston.
New York-based Abundia used its proprietary pyrolysis process to convert plastic and certified biomass waste into high-quality renewable fuels. Its founder, Ed Gillespie, will serve as CEO of the combined company and will join HUSA’s board of directors. Peter Longo, who previously served as HUSA's CEO, will serve as chairman of the board. Lucie Harwood was named CFO and Joseph Gasik will serve as COO.
“The completion of this acquisition represents a pivotal transformation for HUSA,” Longo said in a news release. “Abundia has a commercially ready solution for converting waste into valuable fuels and chemicals, with a backlog of development opportunities utilizing proprietary technologies and key industry partnerships. This transaction gives HUSA shareholders a ready-made platform and project pipeline for future value generation as the fuel and chemical industries accelerate their adoption of low-carbon solutions and sustainable aviation fuel.”
The combined company plans to serve what it estimates is a multi-billion-dollar global demand for renewable fuels, Sustainable Aviation Fuel (SAF) and recycled chemical feedstocks, according to the news release.
“This is a landmark moment for Abundia and a major step forward for the renewable industry,” Gillespie added in the release. “Joining forces with HUSA and entering the public capital markets positions us to accelerate growth, scale our technology and expand our influence within the renewable and recycling industries. I am proud of the hard work and determination of both the AGIG and HUSA teams to finalize this transaction. We look forward to delivering shareholder value and critical technologies to reduce carbon emissions.”
Houston American Energy announced the deal in March. The company also closed a $4.42 million registered direct offering in January.
