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.

Why this growing Chilean clean energy company moved its HQ to Houston

future of farming

In Houston, air pollution is usually more of an abstract concept than a harsh reality. But in parts of Chile, the consequences of heating homes with wet wood are catching up to residents.

“Given all the contamination, there are times kids aren’t allowed to go to school. The air pollution is really affecting people’s health,” says Agustín Ríos, COO of Lignium Energy.

Additionally, the methane and nitrous oxide produced by cattle farming are a problem. But Lignium Energy, an international company started in Chile and now headquartered in Houston’s Greentown Labs, has a solution that can solve both problems by upending the latter.

“There’s a lack of solutions with the problem of manure. Methane gases are destroying our planet,” says CEO and co-founder Enrique Guzmán. He goes on to say that most solutions currently being developed are expensive and complex. But not Lignium Energy’s method, invented by co-founder José Antonio Caraball.

Caraball has patented an extraordinarily simple concept. Lignium separates the solid from liquid excretions, then cleans the solid to generate a hay-like biomass. Biomass refers to organic matter that can be used as fuel. What Lignium makes from the cattle evacuations is a clean, odorless and highly calorific biomass.

Essentially, Lignium combats greenhouse gasses with a green fuel that boasts an enviably low carbon footprint. “Our process is very cheap and very simple. That’s why we are a great solution,” explains Guzmán.

Caraball, an industrial engineer, came up with the idea six years ago, says Guzmán. Five years ago, he began working with the company, one year ago, Guzmán and Ríos picked up and moved to Houston.

“We decided to move out of Chile due to market size,” says Ríos. However, the product is already being sold to consumers in its homeland.

Why Houston? The reason was twofold. As an energy company, Ríos says that they wanted to be in “the energy capital of the world.” But Texas is also one of the largest sites of cattle farming on the planet. Lignium prefers to work with farms with more than 500 head to optimize harvesting the waste that becomes biomass.

With that in mind, Lignium has partnered with Southwest Regional Dairy Center in Stephenville, Texas, a little more than an hour southwest of Fort Worth, a town known as the world’s rodeo capital. The facility is associated with Texas A&M, though Guzmán says Lignium is not officially associated with the university.

Guzmán says that the company is currently hiring a team member to help Lignium figure out commercial logistics, as well as four or five other Houstonians who will help them take their product to market in the United States, and eventually around the globe. For now, he predicts that they will be able to sell to consumers in this country by early next year, if not the fourth quarter of 2023.

“We are very committed to the solution because, at the end of the day, if we do good work with the company, we are sure we can give better conditions to the cattle industry,” says Guzmán. “Then we can make a big impact on a real problem.

Houston developer launches AI-powered water platform to boost efficiency

eyes on AI

Houston real estate company McCord Development has launched an artificial-Intelligence-run water management platform, MizuWatch.

MizuWatch aims to help operators, districts, and municipalities detect leaks faster, reduce water loss and improve efficiency, according to the company. MizuWatch pulls data from supply sources, smart meters, historical usage and maintenance records, and combines them into a single platform. The AI system also uses visual mapping and digital twin technology to deliver near-real-time system insights.

“MizuWatch brings the right data together daily, so teams can see what’s happening now, intervene earlier and focus their resources where they have the greatest impact,” Jerzy Wielgus, chief product officer for MizuWatch, said in a news release.

MizuWatch was built to “scale across geographies and system sizes to help assist with water scarcity, aging infrastructure, and operational complexity,” according to the company. It was developed at Houston’s Generation Park, McCord’s 4,300-acre master planned commercial district. McCord was able to pilot the platform onsite to help manage its complex, real-world water systems at scale.

“Resilient infrastructure is a key factor for the companies choosing Generation Park,” Ryan McCord, CEO of McCord Development and Founder & CEO of MizuWatch, added in the release. “We made the decision to deploy smart meters, but no one knew how to use the data they generate. This is an opportunity across all infrastructure where sensors are deployed. What started as an internal solution has become a platform we believe can help stakeholders everywhere be more efficient in their operations, investment, and compliance.”

Last fall, Eli Lilly and Co. selected Generation Park for its $6.5 billion manufacturing plant. More than 300 locations in the U.S. competed for the factory. Bristol Myers Squibb Co., another pharmaceutical giant, also announced it is considering Generation Park for a new manufacturing hub earlier this month.

Oil giant BP ousts new chairman over serious conduct concerns

Sudden Exit

BP has ousted its chairman over what it called serious concerns related to “important governance standards, oversight and conduct.”

The departure was abrupt and unexpected, with Albert Manifold having been appointed to the position late last year.

“Albert has helped bring a welcome focus and pace to BP’s transformation," Amanda Blanc, senior independent director, said in a statement Tuesday, May 26. "However, the board has been surprised and disappointed to learn of governance oversight and conduct issues it deems unacceptable and has taken decisive action.”

BP's board named Ian Tyler as interim chair, effective immediately.

BP, based in London and with North American headquarters in Houston, is a “supermajor,” one of the five largest oil production and exploration companies in the world when measured by revenue and profit.

Manifold, who had been the top executive at Dublin-based global building materials company CRH for 10 years, became the chair at BP in October. BP was looking for someone to revamp the oil giant and went with an industry outsider in Manifold, who had made major strategic changes at CRH.

After a new focus on renewable energy at BP in 2020, by 2025 the company was seeking a return to its roots. BP's hard reset was criticized by environmentalists, as well as some shareholders.

CEO Murray Auchincloss said last year that optimism over opportunities in renewable energy was misplaced, with the company moving “too far and too fast.”

Changes in leadership at BP in recent years has been tumultuous.

CEO Bernard Looney resigned in late 2023 after BP determined that he had misled the company over his past relationships with colleagues.

Auchincloss stepped down in December, and the company named Meg O'Neill as his successor.

Manifold’s was challenged almost immediately when shareholders defeated company resolutions this spring that would have allowed BP to reduce climate reporting requirements and move its annual meetings fully online. Some 18% of shareholders voted against Manifold’s election as chairman, a high level of opposition for an appointment that is generally rubber stamped by investors.

Legal & General, one of Britain’s largest insurers and investment companies, said at the time that Manifold was responsible for resolutions that would have had “a negative impact on shareholders’ insight into how the company is addressing financially material long-term risks, and seizing long-term value creation opportunities, associated with the energy transition,” the Times of London reported on April 23.

Glass Lewis, an influential shareholder advisor, urged investors to vote against Manifold’s election. It held that BP took “unprecedented action” by refusing to consider a resolution from a group of climate activists and pension funds hoping to force the board to create an alternative strategy should demand for fossil fuels decline, the Times reported.

Like other big oil companies, BP has struggled with falling demand in recent years.

BP’s 2025 earnings fell 16% from a year earlier to $7.49 billion as the price of Brent crude, a benchmark for international oil prices, dropped 16.9%. The company’s preferred measure of earnings is underlying replacement cost profit, which adjusts for one-time items and fluctuations in the market value of inventories. Net income plunged 86% to $55 million.

Last year there were media reports that British oil giant Shell was in talks to buy rival BP. Shell denied the reports at the time.

The search for a new chair is underway, BP said Tuesday. Shares of BP Plc slid nearly 5% in midday trading on the NYSE.

Houston startup nets new funding to accelerate methane leak detection

fresh funding

Houston climatech startup Aquanta Vision has secured pre-seed funding to accelerate the commercialization of its methane leak detection software.

EIC Rose Rock participated in the round, joining investors like Marathon Petroleum Corporation, Chevron Technology Ventures, Ecosphere Ventures, and Odyssey Energy Advisors. The investment follows successful field trials for Aquanta Vision’s optical gas imaging (OGI) detection software, according to the company.

“This investment highlights our shared excitement as our patented novel technology improves detection levels for OGI camera operators,” Babur Ozden, Aquanta Vision’s CEO and founder, said in a news release. “The funding from EIC Rose Rock enables us to strategically accelerate this impact.”

Aquanta Vision’s OGI technology features an automated detection layer through an add-on app that improves methane detectability without requiring new hardware. It installs in minutes, runs locally and provides real-time, in-flight plume visualization for inspections with drone-mounted and handheld cameras.

“We are excited to partner with Aquanta Vision to scale and deploy this world-class technology that enables the energy industry to continue to deliver the secure, reliable and affordable energy that drives the American economy,” David Clouse, managing director of the EIC Rose Rock fund, added in the news release.

The company has partnered with Teledyne Flir and Sierra Olympia, makers of one of the world’s largest deployed fleet of handheld and drone-mounted optical gas imaging cameras used in industrial inspections. AquantaVision is now working with Teledyne Flir’s product team, as well as Sierra Olympia and its OEM partners.

Aquanta Vision has estimated that methane leaks cost the U.S. energy industry billions of dollars each year, with 60 percent of leaks going undetected, and methane leaks accounting for around 10 percent of natural gas's contribution to climate change, according to MIT’s climate portal.
