A Rice University professor wants to redraw the map for the placement of electric vehicle charging stations to level the playing field for access to EV power sources.

Xinwu Qian, assistant professor of civil and environmental engineering at Rice, is leading research to rethink where EV charging stations should be installed so that they’re convenient for all motorists going about their day-to-day activities.

“Charging an electric vehicle isn’t just about plugging it in and waiting — it takes 30 minutes to an hour even with the fastest charger — therefore, it’s an activity layered with social, economic, and practical implications,” Qian says on Rice’s website. “While we’ve made great strides in EV adoption, the invisible barriers to public charging access remain a significant challenge.”

According to Qian’s research, public charging stations are more commonly located near low-income households, as these residents are less likely to afford or enjoy access to at-home charging. However, these stations are often far from where they conduct everyday activities.

The Rice report explains that, in contrast, public charging stations are geographically farther from affluent suburban areas. However, they often fit more seamlessly into these residents' daily schedules. As a result, low-income communities face an opportunity gap, where public charging may exist in theory but is less practical in reality.

A 2024 study led by Qian analyzed data from over 28,000 public EV charging stations and 5.5 million points across 20 U.S. cities.

“The findings were stark: Income, rather than proximity, was the dominant factor in determining who benefits most from public EV infrastructure,” Qian says.

“Wealthier individuals were more likely to find a charging station at places they frequent, and they also had the flexibility to spend time at those places while charging their vehicles,” he adds. “Meanwhile, lower-income communities struggled to integrate public charging into their routines due to a compounded issue of shorter dwell times and less alignment with daily activities.”

To make matters worse, businesses often target high-income people when they install charging stations, Qian’s research revealed.

“It’s a sad reality,” Qian said. “If we don’t address these systemic issues now, we risk deepening the divide between those who can afford EVs and those who can’t.”

A grant from the National Science Foundation backs Qian’s further research into this subject. He says the public and private sectors must collaborate to address the inequity in access to public charging stations for EVs.

A Houston company has announced the completion of its new high-speed electric vehicle charging site.

The bp pulse branded Gigahub at bp's Houston campus — the first of its kind with its 24 high-speed charge points — is ready to power up EVs, Arcadis, a global design and consultancy organization for natural and built assets, announced.

"The opening of our first bp pulse Gigahub is a major step in bp pulse's plans to build out a national EV charging network," Sujay Sharma, CEO, bp pulse Americas, says in a news release. "EV drivers need access to reliable, fast, on-the-go charging to enable an exceptional customer experience. Working with leaders in the space, like Arcadis, is allowing us to deliver the charging experience EV drivers need in Houston and beyond."

The firm also reported that solar panel parking canopies might be added to the facility later, as well as expanding to include restrooms, a lounge, and convenience store, if needed. bp originally announced the project in March.

"We are proud to work with bp pulse on energy transition projects such as these that accelerate a planet positive future," Brooke Bonkoski, president of Resilience Environment US at Arcadis, adds. "Arcadis, like bp, is committed to moving the energy transition forward. Delivering this project in the City of Houston, the energy capital of the world, is particularly impactful."

New Houston study shows health impacts of full vehicle electrification in major U.S. cities

what could be

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 said in a statement.

However, Mousavinezhad and Choi found that full electrification in Los Angeles could have negative impacts on public health.

Switching fully to electric vehicles could prevent 157 premature deaths each month in Houston, 796 deaths in New York and 328 in Chicago, according to the study. But in Los Angeles, full electrification would increase mortality.

Additionally, full electrification would save between $51 million to $249 million per day for New York, Chicago, and Houston in health-related costs. But Los Angeles would face economic losses of up to $18 million per day.

This was largely due to the unique weather and geography in Los Angeles that can trap air pollutants that harm the lungs. The study found that full electrification would lead to increases in PM2.5 and MDA8 ozone. According to UH, the study reveals the importance and "complexity of air quality management."

“The four largest U.S. cities have distinct anthropogenic sources of air pollutants and greenhouse gases, “Choi added. “Each city requires unique regulations or strategies, including different scenarios for the adoption of electric vehicles, to reduce concentrations of these pollutants and greenhouse gases effectively.”

Mousavinezhad, lead author, is a recent Ph.D. graduate from UH. Choi is a professor of atmospheric chemistry, AI deep learning, air quality modeling and satellite remote sensing. The study, titled “Air quality and health co-benefits of vehicle electrification and emission controls in the most populated United States urban hubs: insights from New York, Los Angeles, Chicago and Houston,” was published in the journal Science of the Total Environment earlier this year.

Earlier this year, Texas ranked low in a study that looked at the closest EV charging stations equivalent to a trip to the gas station. However, another study showed that Texas is among the top of the pack for states with the most electric vehicle registrations, but Houston fell behind other large metros in the state for EV friendliness.

Electric vehicles to take center stage at annual Houston event

vroom, vroom

Houston Auto Show, which is a long running event for auto enthusiasts, will feature its largest electronic vehicle representation to date this year.

The event will feature an EV Pavillion and Evolve Houston’s electronic showroom at the January 24 to 28 event at NRG Center. Attendees will have the opportunity to learn about what it means to go the EV route from environmental impact, performance, cost effectiveness, and other factors.

This year, vehicles like Nissan's Ariya Platinum+ AWD, Chevrolet’s Bolt EV, Ford’s F-150 Lightning and others will be on display at the EV Pavillion. CenterPoint Energy, Reliant, and the University of Houston were part of Evolve's 2023 showroom.

A recent study from SmartAsset ranked states with the most electric vehicle chargers by looking at the closest equivalent to a trip to the gas station, in terms of “refueling” – per capita. Texas is behind other similarly-sized states.

“Houston maintains some of the lowest population density and longest commute distances of major U.S. cities, and we have an immense amount of business and goods that flow through Houston,” Casey Brown, executive director and president of EVOLVE, previously told EnergyCapital. “We see a landscape that can uniquely achieve larger financial and environmental benefits of EV technologies. One way that we share these benefits is being the Presenting Sponsor of the Houston Auto Show.”

Houston Automobile Dealers Association Executive Vice President and event organizer RoShelle Salinas has noted there has been an uptick in EV demand for these events since the first one debuted at the 2020 show.

Evolve Houston, which was founded in 2018 through Houston’s Climate Action Plan, is one of the organizations leading the way in the EV space, as the company still aims for its goal to have half of the vehicles in the city be electric by 2030. Evolve assists and funds those looking to make the transition to electric with the Grant Tracker, which aims to make it easier to find funding opportunities, and assist with current grants available to organizations and individuals that are committed to a goal of zero emissions. The tracker serves as a tool to assist with purchasing an EV and charging equipment.

The Biden administration recently announced it is awarding $623 million in grants to help build an electric vehicle charging network across the nation. Grants will fund 47 EV charging stations and related projects in 22 states and Puerto Rico, including 7,500 EV charging ports according to officials. Texas is expected to see a chunk of that funding. Last year, the city of Houston approved $281,000 funding for the expansion of free electric vehicle rideshare services in communities that are considered underserved by utilizing services like RYDE and Evolve Houston.

“Evolve Houston has been a sponsor for 2 years and their display has been a great addition to the show because it is not only educational, but there is also a chance for people to test drive vehicles,” Salinas says.

Texas finishes low on list of EV charging stations despite increased efforts in Houston

by the numbers

In a new report that ranked states with the most electric vehicle chargers, Texas falls behind other similarly-sized states

The SmartAsset study looked at the closest EV charging stations equivalent to a trip to the gas station — factoring in each state's population. California, with its 14,500 charging stations, has five times the EV charging stations as New York (3,327), Florida (2,913) and Texas (2,472). While California ranked No. 1 on the list, Texas found itself at No. 41.

The report used EV charger and station data for each state from the U.S. Department of Energy for 2022 and 2021. Population data is for 2022 and comes from the U.S. Census Bureau 1-Year American Community Survey. Cities were also ranked by the number of fast chargers per capita. In 2022, Texas had 1,386 fast DC chargers, 2,472 EV charging stations, and a fast charger growth year over year 53.5 percent.

Interest in electric vehicles ranked low in Texas according to a 2023 study by University of Houston and Texas Southern University. The Texas Trends survey revealed just 5.1 percent of Texans currently drive an electric-powered car, truck, or SUV, while 60 percent said they were not too likely or not at all likely to consider leasing or purchasing an electric vehicle in the future.

Even though in Texas, the interest in EVs may seem low, but Houston is trying to incorporate more innovation in this area. The city of Houston approved $281,000 funding for the expansion of free electric vehicle rideshare services in communities that are considered underserved by utilizing services like RYDE and Evolve Houston in December. The funding will be dispersed to RYDE in through the nonprofit Evolve Houston. Luxury rideshare company Alto, which currently operates in Inner Loop and Greater Houston, expanded its current service areas to The Woodlands and Spring, which will include an expanded fleet of EVs.

Another study showed that Texas is among the top of the pack for states with the most electric vehicle registrations, but Houston fell behind other large metros in the state for EV friendliness. The report from StorageCafe showed that Texas had the third-most EV registrations in the county in 2021 at 112,000 vehicles. California outpaced the rest of the country with 878,000 registrations for the No.1 ranking. The report found that Houston drivers registered 27,251 EVs in 2021.

Texas to receive $70M to build EV charging network

follow the funding

The Biden administration is awarding $623 million in grants to help build an electric vehicle charging network across the nation, and Texas is expected to see a chunk of that funding.

Grants being announced Thursday will fund 47 EV charging stations and related projects in 22 states and Puerto Rico, including 7,500 EV charging ports, officials said.

“America led the arrival of the automotive era, and now we have a chance to lead the world in the EV revolution — securing jobs, savings and benefits for Americans in the process,” said Transportation Secretary Pete Buttigieg. The new funding “will help ensure that EV chargers are accessible, reliable and convenient for American drivers, while creating jobs in charger manufacturing, installation and maintenance for American workers.”

Congress approved $7.5 billion in the 2021 infrastructure law to meet President Joe Biden's goal of building out a national network of 500,000 publicly available chargers by 2030. The charging ports are a key part of Biden's effort to encourage drivers to move away from gasoline-powered cars and trucks that contribute to global warming.

But progress on the network has been slow. Ohio and New York are the only states that have opened charging stations under the National Electric Vehicle Infrastructure program. Several other states, including Pennsylvania and Maine, have broken ground on federally funded projects and are expected to open stations early this year. A total of 28 states, plus Puerto Rico, have either awarded contracts to build chargers or have accepted bids to do so.

The grants announced Thursday include $311 million to 36 “community” projects, including two Native American Tribes in Alaska and Arizona. The projects will boost EV charging and hydrogen fueling infrastructure in urban and rural communities, including at high-use locations such as schools, parks, libraries and apartment buildings.

About $70 million will go to the North Central Texas Council of Governments to build up to five hydrogen fueling stations for medium- and heavy-duty freight trucks in Dallas-Fort Worth, Houston, Austin and San Antonio. The project will help create a “hydrogen fueling corridor” from southern California to Texas.

Another $312 million in funding will go to 11 highway “corridors” along roadways designated as Alternative Fuel Corridors. The projects include $19.6 million for publicly accessible EV charging facility in Riverside County California, located midway between Los Angeles and Phoenix on the I-10 corridor. The project includes installation of six large chargers for heavy-duty vehicles and 30 fast chargers for light-duty vehicles; solar and battery energy storage systems; and amenities such as rest areas.

A pollution district in San Joaquin Valley, California will receive $56 million to build two state-of-the-art truck charging sites in Taft and Gustine, California, to support two of the nation’s busiest freight corridors along I-5. The sites will feature 90 fast chargers for passenger vehicles, 85 fast chargers for medium to heavy-duty EVs and 17 large chargers. The sites will also enhance grid stability with 63 acres of solar panels and battery electric storage systems.

Another $15 million will go to the Maryland Clean Energy Center to build 87 EV charging stations in urban, suburban and low- and moderate-income communities across the state. Proposed sites include Coppin State University, a historically Black school in Baltimore, and 34 disadvantaged communities with multi-family housing.

Since Biden took office in 2021, EV sales have more than quadrupled and reached more than 1 million last year. The number of publicly available charging ports has grown by nearly 70 percent to 168,426, White House climate adviser Ali Zaidi said.

That number is about one-third of the way to Biden's goal, with six years remaining.

“We are on an accelerating trajectory to meet and exceed the president’s goal to hit 500,000 chargers and build that nationwide backbone,'' Zaidi told reporters Wednesday.

Widespread availability of chargers is crucial to meet another Biden administration goal: ensuring that EVs make up half of all new car sales by 2030. Along with cost, “range anxiety” about a lack of available charging stations is a key impediment to buying an EV. About 80 percent of respondents cited concerns about a lack of charging stations as a reason not to purchase an electric vehicle, according to an April survey from The Associated Press-NORC Center for Public Affairs Research and the Energy Policy Institute at the University of Chicago.

Seven in 10 respondents said they would not purchase an EV because they take too long to charge and the battery technology isn’t ready.

Buttigieg and other administration officials brushed those concerns aside and said the future of auto travel is electric.

“We’re at a moment now where the electric vehicle revolution isn't coming. It is very much here,'' Buttigieg told reporters. EV sales now represent about 9 percent of all passenger vehicle sales, Buttigieg said — a huge increase since Biden took office. He cited a new study showing that EV's cost just 4 percent more than gasoline-powered cars.

"There's been a really remarkable drop in the prices that consumers face for EVs. And we believe we are fast approaching the period when EVs, on average, will be cheaper than internal combustion vehicles,'' Buttigieg said.

8 Houston energy companies land on Time's top greentech list for 2025

top honor

The accolades keep rolling in for Houston-based Fervo Energy, a producer of geothermal power.

Fervo lands at No. 6 on Time magazine and Statista’s new list of America’s Top GreenTech Companies of 2025. The ranking recognizes sustainability-focused companies based on factors such as impact, financial strength, and innovation.

Time notes that Fervo broke ground in 2023 in Utah on what the company claims will be the world’s largest geothermal plant. The plant is scheduled to start supplying carbon-free electricity to the grid next year and to reach its 400-megawatt capacity in three years.

“Technologies like this only make a difference if we deploy them at large-scale in a way that can reduce carbon emissions and increase the reliability of the grid,” Fervo CEO Tim Latimer told Time in 2023.

The startup was named North American Company of the Year by research and consulting firm Cleantech Group for 2025. Fervo topped the Global Cleantech 100, Cleantech Group’s annual list of the world’s most innovative and promising cleantech companies.

Last year, Fervo also made Time’s list of the 200 Best Inventions of 2024. Fervo was recognized in the green energy category for its FervoFlex geothermal power system.

Founded in 2017, Fervo is now a unicorn, meaning its valuation as a private company exceeds $1 billion. The startup’s valuation is estimated at $1.4 billion. According to PitchBook data, the company raised $634 million in the fourth quarter of 2024.

In all, eight Houston-area companies appear among the top 250 greentech companies ranked by Time and Statista. Other than Fervo, they are:

No. 43 Lancium Technologies, an energy storage and distribution company
No. 50 Solugen, a producer of sustainable chemicals.
No. 56 Quaise Energy, which specializes in terawatt-scale geothermal power.
No. 129 Plus Power, a developer, owner and operator of battery storage projects.
No. 218 Dream Harvest, which promotes sustainable vertical farming.
No. 225 Cemvita, which uses synthetic biology to convert carbon emissions into bio-based chemicals.
No. 226 Syzygy Plasmonics, which decarbonizes chemical production.

Vermont-based BETA Technologies claimed the No. 1 spot. The company manufactures electric aircraft.
