Two professors at the University of Houston have developed an autonomous subsea vehicle that aims to decrease the number and severity of oil spills.

Known as SmartTouch technology, the Remote Operated Vehicles (ROVs) use smart touch sensors, video cameras and scanning sonars to inspect flange bolts in subsea pipelines, which are considered to lead to increased rates of leakage, according to a release from the university.

The ROVs, developed by UH's Zheng Chen and Gangbing Song, will provide a safer and more cost effective alternative to pipeline inspections, which are traditionally performed by human divers and require a great deal of time and money.

“By automating the inspection process with this state-of-the art robotic technology, we can dramatically reduce the cost and risk of these important subsea inspections which will lead to safer operations of offshore oil and gas pipelines as less intervention from human divers will be needed,” Chen, the Bill D. Cook Assistant Professor of Mechanical Engineering, said in a statement.

The technology will also be highly accurate in monitoring corrosion, which according to Song, the John and Rebecca Moores Professor of Mechanical Engineering, is responsible for most small leaks in subsea pipelines.

The project is funded by a $960,000 grant from the Bureau of Safety and Environmental Enforcement (BSEE), which is a part of the U.S. Department of the Interior. Chen and Song are also collaborating with Houston-based Oceaneering International on the development of the ROVs, which Oceaneering specializes in. Energy giant Chevron will evaluate the technology’s future commercialization, according to UH, and preliminary studies were funded by the university's Subsea Systems Institute.

Thus far, a prototype of the ROVs has been tested in Chen's lab at UH and in Galveston Bay. Experiments showed the technology's ability to inspect the looseness of subsea bolted connections, like flange bolts.

Chen and Song see other applications for their technology, as well.

"Ultimately, the project will push the boundaries of what can be accomplished by integrating robotics and structural health monitoring technologies," Chen added in the statement. "With proper implementation, the rate of subsea pipeline failure and related accidents will decrease, and subsea operations will be free to expand at a faster rate than before.”

Earlier this summer the UH Subsea Systems Institute and SPRINT Robotics teamed up to develop a robotics training program for the energy industry known as “Robotics in Energy.” The first of a series of two-day courses debuted in May and a subsequent course, Automation & Autonomy, will launch next month. Others are expected to be rolled out in the future as part of the university's Micro-Credentialing Programs in UH Energy.

Additionally Chevron and UH partnered up again last month to announce its inaugural cohort of UH-Chevron Energy Graduate Fellows.

A new study from FinanceBuzz reports that Texas has the fifth most public electric vehicle charging stations among states in the U.S.

In its Electric Vehicle (EV) Statistics [2025]: Trends in Sales, Savings, and More report, FinanceBuzz, a personal finance and investment adviser, compiled electric vehicle data to find sales trends, adoption rates, charging infrastructure, costs, savings and more.

Texas has a total of 3,709 public EV charging stations, which equals about 16 stations per 1,000 EVs, according to the report. The remaining top five included:

  • No. 1 California with 17,122 EV charging stations
  • No. 2 New York with 4,814 EV charging stations
  • No.3 Massachusetts with 3,738 EV charging stations
  • No. 4 Florida with 3,715 EV charging stations

Los Angeles had the most public charging stations at 1,609 among U.S. cities. Austin was Texas’s top city with 656 stations.

The study also looked at how much Americans are spending on transportation, and found that the average American using a gas vehicle spends $1,865 annually on fuel. FinanceBuzz found that electric vehicle owners would pay 65 percent less on energy costs. Calculations were based on driving 14,489 miles annually, which measures to 37.9 miles per day. The full report sourced data from the International Energy Agency, the U.S. Department of Energy, the U.S. Department of Transportation, AAA, the U.S. Energy Information Administration and other organizations.

The report said Americans purchased over 1.5 million EVs in 2024, which equals approximately 10 percent of all new light-duty vehicles sold, citing information from the International Council on Clean Transportation.

While Tesla remains the most popular make, 24 new EV models were launched in 2024 by other companies, which represents a 15 percent increase from the previous year.

Other trends in the report included:

  • The U.S. now has more than 64,000 public charging stations and over 168,000 charging ports, which is up from fewer than 1,000 stations in 2010.
  • An average EV owner will spend about $654 per year on electricity, compared to $1,865 for a gas-powered vehicle. The savings equate to about $1,211 per year.
  • In 2024, U.S. EV sales surpassed 1.5 million, but the pace slowed compared to the previous year, with a 10 percent increase versus 40 percent in 2023.
  • Insuring an EV can be more costly because parts are harder to come by, making repairs and replacements more expensive.
  • In the second quarter of 2024, nearly half of new EVs were leased, which is a 28 percentage point increase since 2021.
