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.

Texas ranks high on new EV study, but Houston was outpaced by other metros

driving toward progress

A new study shows that Texas is among the top of the pack for states with the most electric vehicle registrations. But Houston falls behind other large metros in the state for EV friendliness.

The March report from StorageCafe, which compiled data from the Federal Transit Administration, the Federal Highway Administration, the Department of Energy and other sources, 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 by a longshot with 878,000 registrations, claiming the number one spot. Florida had the second-most registrations at 128,000.

The report also looked at EV friendliness, which factored in EV registrations as well as the number of charging stations per household, EV exemptions, incentives and various other factors.

Houston was ranked 32nd on the friendliness list. The report found that Bayou City drivers registered 27,251 EVs in 2021. Charging stations are available in about 3.8 percent of rental buildings and there are 0.2 charging stations for every 1,000 households in the city.

Dallas claimed the top spot for the state at No. 15 with more than 29,000 EV registrations in 2021. Though Dallas has the same ratio of EV charging stations per household, there are more charging stations in rental buildings in the city.

Austin, at No. 22, also outranked Houston. Though the capital city only registered 8,730 EVs in 2021 there are much more charging stations per household (0.7 for every 1,000) and in rental buildings (5.5 percent).

San Antonio came in at No. 36, the McAllen area at No. 75, and El Paso at No. 83.

Seattle was named the friendliest place to own an EV. The drivers in the city registered more than 47,000 EVs in 2021.

Doug Ressler, a business intelligence manager at Yardi Matrix, which contributed to the report, weighed in on the findings.

“The electric car movement is gaining momentum, but it isn’t without its challenges. The high price of an EV–although brought down by incentives now – range and charging stations still pose some problems," he said in a statement. "However, with the expansion of the charging network–including in apartment buildings–and the gradual lowering of the EV price, buying and using an EV can become mainstream in the foreseeable future."

He also estimated that EVs will "dominate the car market" by 2045. By 2050, he said EVs could make up about 90 percent of the market.

Earlier this month Hertz announced that it would triple Houston's electric rental fleet, as well as add a fast-charging hub to Hobby Airport that's designed to serve ride-hail, taxi fleets and the general public.

Emission-free hydrogen research, Enron's return, and more trending Houston energy news

top stories

Editor's note: From Caliche Development Partners finding fresh funding for a Beaumont plant to an energy transition SPAC going public, these are the top headlines that resonated with EnergyCapital readers on social media and daily newsletter this week.

Houston researchers develop catalyst for emission-free hydrogen production using light instead of heat

Researchers at Rice University have developed a catalyst that could render steam methane reforming, or SMR, entirely emission-free by using light rather than heat to drive the reaction.

The researchers believe the work could prove to be a breakthrough for extending catalyst lifetimes. This will improve efficiencies and reduce costs for a number of industrial processes that are affected by a form of carbon buildup that can deactivate catalysts called coking.

The new copper-rhodium photocatalyst uses an antenna-reactor design. When it is exposed to a specific wavelength of light it breaks down methane and water vapor without external heating into hydrogen and carbon monoxide. The importance of this is it is a chemical industry feedstock that is not a greenhouse gas. Rice’s work also shows that the antenna-reactor technology can overcome catalyst deactivation due to oxidation and coking by employing hot carriers to remove oxygen species and carbon deposits, which effectively regenerates the catalyst with light.

An elaborate parody appears to be behind an effort to resurrect Enron, the Houston-based energy company that exemplified the worst in American corporate fraud and greed after it went bankrupt in 2001.

If its return is comedic, some former employees who lost everything in Enron’s collapse aren’t laughing.

“It’s a pretty sick joke and it disparages the people that did work there. And why would you want to even bring it back up again?” said former Enron employee Diana Peters, who represented workers in the company’s bankruptcy proceedings. Continue reading.

The New Mexico Court of Appeals has upheld regulations aimed at cracking down on emissions in one of the nation’s top-producing oil and gas states.

The case centered on a rule adopted in 2022 by state regulators that called for curbing the pollutants that chemically react in the presence of sunlight to create ground-level ozone, commonly known as smog. High ozone levels can cause respiratory problems, including asthma and chronic bronchitis.

Democratic Gov. Michelle Lujan Grisham's administration has long argued that the adoption of the ozone precursor rule along with regulations to limit methane emissions from the industry were necessary to combat climate change and meet federal clean air standards. Continue reading.

Aramco partners to demonstrate compact carbon capture technology for gas turbines

dream team

Integrated energy and chemicals company Aramco has signed a collaboration agreement with Carbon Clean and SAMSUNG E&A in an effort to showcase new carbon capture technology.

The technology demonstration will be used to deploy Carbon Clean’s novel CycloneCC technology to capture CO2 from natural gas turbine exhaust streams containing approximately 4 percent CO2, according to Aramco.

Carbon Clean, which U.S. headquarters are located in Houston at the Ion, boasts technology that has captured nearly two million tons of carbon dioxide at almost 50 sites around the world. Aramco’s U.S. headquarters is also in Houston.

“The potential for CycloneCC in the US and Houston area is huge,” Aniruddha Sharma, chair and CEO of Carbon Clean, previously shared with EnergyCapital. “It is optimised for low to medium scale industrial emitters and recent Rice University research on the US Gulf Coast, for example, found that it is well suited to 73 percent of Gulf Coast emitters.”

The modular CycloneCC unit has a 50 percent smaller footprint compared to conventional carbon capture processes. The CycloneCC technology is estimated to reduce the total installed cost of carbon capture systems by up to 50 percent compared to conventional systems if successful. The goal is to also maintain process efficiency even at low CO2 concentrations. CycloneCC’s performance is achieved through two process intensification technologies, rotating packed beds (RPBs) and Carbon Clean’s proprietary APBS-CDRMax solvent.

“Its compact, modular design should be easily integrated with gas turbines, delivering high performance carbon capture in an industrial setting where space is typically limited,” Sharma says in a news release.

The engineering, procurement and construction of the plant will be done by SAMSUNG E&A .The unit will be installed on the sales gas compressor turbine exhaust gas stack,which can provide performance data under real-world conditions.

“Aramco and Samsung Ventures are investors in Carbon Clean, so we’re proud to deepen our relationship through this partnership,” Sharma adds. “This first-of-a-kind deployment capturing very low concentrations of CO2 is a key milestone in scaling up and commercializing CycloneCC.”

In September, Carbon Clean also announced a deal with PETRONAS CCS Solution to collaborate and evaluate Carbon Clean’s carbon capture and storage technology with Carbon Clean's CycloneCC tech. Last year, Abu Dhabi National Oil Co. (ADNOC) selected Carbon Clean for a carbon capture project in Abu Dhabi.
