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.

Baker Hughes signs deal to install 500 MW of geothermal power

geothermal growth

Baker Hughes has made a deal to further expand its geothermal operations.

The Houston-based energy giant has signed an agreement with Mantle Reach Power to develop geothermal energy projects across North America. The companies say they aim to install up to 500 megawatts of geothermal power in the next five years, according to a news release.

Through the new agreement, Baker Hughes will provide subsurface technology and solutions while Mantle Reach Power will lead project development, ownership and financing. Mantle Reach Power is a geothermal development company backed by the $47 billion EnCap Energy Transition Fund III.

According to the release, the deal aims to help solve one of geothermal energy's fundamental problems by aligning capital with expertise and technology, and enhancing "pre-construction bankability."

“Geothermal is a clean power solution that is proving to be a vital contributor to advancing sustainable energy development, with incredible potential to enhance U.S. energy security, support digital infrastructure, and ensure energy remains accessible and affordable ... Today’s announcement celebrates the commercial architecture the industry has been missing: a repeatable, financeable model that can be deployed at the speed and scale to meet global energy demands,” Baker Hughes Chairman and CEO Lorenzo Simonelli said in the news release.

“Integrating Baker Hughes’ subsurface-to-surface expertise with our capabilities in project development, finance, and execution positions Mantle Reach Power to commercialize geothermal assets at scale,” Nick Karambelas, CEO of Mantle Reach Power, added in the release. “This structure provides the construction and operating certainty necessary to access conventional project financing and accelerate our growth as an independent power producer.”

Baker Hughes has launched multiple geothermal partnerships in recent months. The company announced a deal with Oklahoma-based Helmerich & Payne Inc. (H&P) in May to develop a geothermal rig, where H&P will provide a geothermal-capable land drilling rig and Baker Hughes will contribute technology.

In March, the company announced support for XGS’s geothermal extraction projects in New Mexico, which are being used to meet the increasing demands of data centers in the state. Last year, Fervo Energy selected Baker Hughes to supply equipment for its flagship geothermal project in Utah.

ENGIE strikes clean energy deal with Houston biomanufacturer

energy match

ENGIE North America has signed an agreement with Aker BioMarine to supply around-the-clock, Texas-sourced clean energy to the Norwegian company's Houston manufacturing facility.

The deal is through ENGIE's 24/7 offering, which allows users to "match electricity consumption with local renewable generation on an hourly basis," rather than annual renewable energy matching, according to a news release.

Houston-based ENGIE NA will match 90% of Aker BioMarine's hourly electricity consumption at its Houston facility through renewable energy certificates that link electricity consumed to clean power generated. The renewable energy will be sourced largely from ENGIE's Impact Solar Project in Lamar County, Texas.

“Working with companies that have made sustainability a core part of their strategy is essential to delivering meaningful progress,” Taymur Bunkheila, regional VP and retail supply lead for ENGIE’s U.S. 24/7 product, said in the release. “By aligning energy solutions with operational needs, we can help organizations improve transparency, strengthen accountability, and deliver measurable outcomes. This agreement demonstrates how companies can take practical steps today while building toward long-term sustainability objectives.”

Aker BioMarine, which develops sustainable marine-based ingredients, processes the majority of its krill and algae products at its Houston facility. The company says the deal with ENGIE marks an important step in reducing the environmental footprint of its operations.

“Through this agreement, we expect to reduce our Scope 2 emissions, marking an important milestone in our broader sustainability journey,” Matts Johansen, CEO at Aker BioMarine, added in the release. “ENGIE has delivered an affordable, innovative and transparent solution that allows us to match our electricity consumption for our Houston manufacturing facility with renewable power generation. The transparent data ENGIE provides strengthens our climate reporting while helping us continue delivering high-quality products with a lower environmental footprint."

ENGIE has more than 11 gigawatts of renewable energy projects in operation or under construction in the U.S. and Canada. The company is targeting 95 gigawatts by 2030
