Houston-based Zeta Energy Corp. has teamed up with an automaker to develop new battery technology.

Zeta Energy and Stellantis N.V. announced a joint development deal to advance battery cell technology for electric vehicle applications that will develop lithium-sulfur EV batteries with gravimetric energy density that can achieve a volumetric energy density comparable to today’s lithium-ion technology. The batteries are targeted to power Stellantis electric vehicles by 2030.

“The combination of Zeta Energy’s lithium-sulfur battery technology with Stellantis’ unrivaled expertise in innovation, global manufacturing and distribution can dramatically improve the performance and cost profile of electric vehicles while increasing the supply chain resiliency for batteries and EVs,” Tom Pilette, CEO of Zeta Energy, says in a news release.

The batteries will be produced using waste materials and methane that boasts lower CO2 emissions than any existing battery technology. Zeta Energy battery technology is intended to be manufacturable within existing gigafactory technology and would leverage an entire domestic supply chain in Europe or North America.

The technology can lead to a significantly lighter battery pack with the same usable energy as contemporary lithium-ion batteries. The companies believe this will enable greater range, improved handling and enhanced performance. The technology has the potential to improve fast-charging speed by up to 50 percent, which can make EV ownership easier.

Lithium-sulfur batteries are expected to cost less than half the price per kilowatt of current lithium-ion batteries according to a news release. Zeta has more than 60 patents on its proprietary lithium-sulfur anode and cathode technologies.

Lighter and more compact EV batteries have become an important design goal for vehicle designers and manufacturers. This objective is similar to what General Motors is doing with prismatic cell technology with LG Energy Solution.

“Our collaboration with Zeta Energy is another step in helping advance our electrification strategy as we work to deliver clean, safe and affordable vehicles,” Ned Curic, Stellantis chief engineering and technology officer, says in the release. “Groundbreaking battery technologies like lithium-sulfur can support Stellantis’ commitment to carbon neutrality by 2038 while ensuring our customers enjoy optimal range, performance and affordability.”

Last year, Zeta Energy announced that it was selected to receive $4 million in federal funding for the development of efficient electric vehicle batteries from the U.S. Department of Energy's ARPA-E Electric Vehicles for American Low-Carbon Living, or EVs4ALL, program.

Houston airports land $12.5M for green projects, announce new EV fleet

seeing green

Houston Airports will receive funding from The Federal Aviation Administration in the next few months on projects aimed at reducing greenhouse gas emissions and implementing the administration's climate challenge guidance at its hubs.

The funds — about $12.5 million — come from the FAA's FY2022 Airport Improvement Program Supplemental Discretionary Grant Competition and are slated to be rolled-out by September 2024. Projects at George Bush Intercontinental and Hobby airports were among 79 projects around the country, which the FAA granted about $268 million to in total.

“Houston Airports is committed to reducing our environmental impact while also protecting the planet as we expand our global reach. These FAA grants fund our ability to invest in smart and sustainable solutions” Jim Szczesniak, COO for Houston Airports, said in a statement. “The end result of these projects will be a more resilient, efficient and sustainable airport system that aligns with the goal of Houston Airports to achieve carbon neutrality by 2030.”

IAH received $10.3 million for two projects that will replace existing generators and fund an energy audit to find energy and water use efficiencies at the airport, as well as "define actionable steps to reduce greenhouse gas emissions across the airfield and the airport's buildings," according to the statement.

Hobby received $2.1 million to also go towards an energy audit and to create a Resiliency Master Plan to help mitigate the impacts of climate change, severe weather and floods in a sustainable way.

Separate from the FAA funds, Houston airports also announced in recent weeks that it will add an all-electric fleet of vehicles for its six airport locations by the end of 2023.

According to a release from HAS, ground operations are a major source of the aviation industry's carbon footprint.

The fleet will include 25 Ford F-150 Lightnings, which can travel up to 320 miles on a full charge. HAS's maintenance team planned to install 11 Level 2 charging stations to support the fleet at its airports this summer.

These updates are all part of HAS's Sustainable Management Plan, which aims to get the system to carbon neutrality by 2030.

Earlier this year, Hertz Electrifies Houston, in partnership with bp pulse, announced that it would install a new EV fast-charging hub to Hobby Airport that's designed to serve ride-hail, taxi fleets and the general public. The initiative, which was formed by The Hertz Corp. and the City of Houston, also aimed to bring 2,100 rental electric vehicles to Houston.

Houston researchers: Texas to face gridlock challenges with reducing emissions in transportation

highway hiccup

A new report found that one of Texas' biggest roadblocks with reducing emissions is its transportation sector.

In its white paper series, the University of Houston's energy researchers found that — unless something changes — the Lone Star State is not likely to hit its carbon neutrality goals by 2050 within the transportation sector.

“What would it take to make the Texas transportation sector net zero by 2050?” Ramanan Krishnamoorti, UH vice president for energy and innovation, says in a news release. “The answer is a miracle, policy interventions that start as soon as possible, and somewhere between 30 to 50 billion dollars of public money between now and 2050 and at least an equal match from the private sector.”

According to the Net Zero in Texas: The Role of Transportation report, over 230 million metric tons of carbon dioxide gas is released from Texas roads each year. By 2050, estimates show that the remaining gasoline and diesel vehicles on the road will still be contributing about 40 million metric tons of emissions. Krishnamoorti collaborated with UH Energy researcher Aparajita Datta on a white paper.

“The future is crucial not only for Texas, where carbon emissions hinge on transportation solutions but also for our nation. Emissions transcend state lines and considering the size of Texas, its growing population and strong industry, the impact is significant,” Krishnamoorti adds.

Some of the challenges the state faces, per the report, hinge on electric vehicle adoption, which has been slow for a variety of reasons. One is the lack of EV production materials, such as lithium, cobalt, copper, manganese and graphite, due to increased demand, which is slated to be increased by 140 to 500 percent.

The EV workforce development also poses a challenge. Right now, hourly wages in the traditional auto sector range from $26 to $60, but most jobs in the EV industry, which are not unionized, range from $17 to $21 per hour.

The call for EV infrastructure is also estimated to be high. Per a news release about the report, "the change will require an annual expenditure of $250 million to $640 million for Level-2 (L2) charging stations and between $500 million and $1.3 billion for DC Fast Charging (DCFC) stations in 2040."

The transition will include an addition of 40,000 and 180,000 jobs in Texas between now and 2050, as well as an estimated $104 billion addition in public health benefits for Texans – fewer deaths, fewer asthma attacks and fewer sick days, according to the study.

“It is evident that decarbonizing Texas’ transportation sector will be a significant challenge and relying solely on consumer behavior to change is unrealistic,” Krishnamoorti says in the release. “We need robust policies to drive the state’s transportation electrification. Let’s acknowledge the journey ahead; federal mandates alone will not guide us to net zero by 2050. Texas needs to act now.”

6 Houston companies earn recognition on Time’s global greentech list 2026

green giants

Six Houston-area businesses appear on Time magazine’s 2026 list of the world’s top greentech companies, with a high-flying name leading the pack.

The highest-ranked local company is Houston-based geothermal power producer Fervo Energy, which claims the No. 4 spot—up from No. 14 last year.

In May, Fervo raised nearly $1.9 billion in its IPO, making it the biggest-ever IPO in the clean energy sector. The company’s valuation now exceeds $10 billion.

Founded in 2017, Fervo borrows methods from the oil and gas sector to drill wells that go down vertically into hot rock before turning horizontal, letting water circulate through them and produce electricity from the heat it absorbs. Cape Station in Utah, the company's first utility-scale project, is set to start delivering power to the grid later this year, with capacity expected to grow to 100 megawatts by 2027.

Co-founder and CEO Tim Latimer tells Fast Company, which named him a 2026 Visionary of the Year, that he launched his career as a drilling engineer for fossil fuels, “but quickly became obsessed with this idea that the drilling techniques we were using would actually be transformative for the world of geothermal as well.”

Fast Company notes the geothermal power generated by Cape Station will be available 24/7, unlike wind and solar power.

“When you start adding something to the grid mix that’s affordable and works around the clock,” Latimer says, “that’s going to be a huge asset to meeting our country’s energy needs.”

Time teamed up with data provider Statista to compile the second annual ranking of the 250 top greentech companies in the world. Companies on the list either develop or provide green technology, products, or services that help ease or reverse the environmental impacts of human activity.

Statista gathered and analyzed data from more than 8,300 companies to create the list, and they were scored in three categories: positive environmental impact, innovation, and financial strength. Fervo earned a score of 94.63 out of 100.

Joining Fervo on this year’s list are:

  • Houston-based Quaise Energy (No. 78), which specializes in terawatt-scale geothermal power
  • The Woodlands-based Plus Power (No. 112), which develops, owns and operates battery storage projects
  • Houston-based Utility Global (No. 167), which develops decarbonization technology
  • Houston-based 1PointFive (No. 217), an Occidental Petroleum subsidiary that offers large-scale carbon removal and storage.
  • Houston-based Sage Geosystems (No. 250), which produces commercial-scale geothermal power

Earlier this year, six Houston-area companies landed on Time's list of top greentech companies in America: Fervo (No. 1), Quaise Energy (No. 49), Plus Power (No. 71), Utility Global (No. 98), Solugen (No. 199) and Noodoe (No. 215).

Houston-based Syzygy lands global customer for first commercial SAF plant

clean fuel deal

Houston-based Syzygy Plasmonics has secured a major future customer for its sustainable aviation fuel.

Syzygy announced this week that it has entered into a capacity reservation agreement with World Fuel Services, a global fuel distribution and logistics company.

Through the deal, World Fuel has reserved a portion of Syzygy's SAF production for future plants slated for Central and South America. The clean fuel will be produced at Syzygy’s NovaSAF-1 facility in Uruguay, which is moving toward construction.

The NovaSAF-1 will be the world's first electrified facility to convert biogas into sustainable aviation fuel (SAF). The facility is expected to produce over 350,000 gallons of SAF annually, which would be considered “a breakthrough in cost-effective, scalable clean fuel,” according to Syzygy.

The facility is expected to produce SAF with at least an 80 percent reduction in carbon intensity compared to Jet A fuel and make its first deliveries in 2028.

"Following NovaSAF-1, this agreement reflects continued interest in scalable pathways for producing SAF from biogas," Trevor Best, CEO of Syzygy Plasmonics, said in a news release. "Our NovaSAF platform is designed to deliver cost-competitive fuel while supporting the aviation sector's evolving regulatory and sustainability requirements."

Syzygy will make a portion of future production capacity available to World Fuel from its planned facilities, subject to the development and completion of those projects, according to the deal.

"We continue to evaluate supply opportunities that support increased access to lower carbon fuels in aviation, in line with emerging regulatory requirements and customer demand," Michael Ranger, senior vice president of supply EMEAA at World Fuel, added in the release. "Arrangements such as this are part of our ongoing efforts across the supply chain.”

Syzygy also secured an offtake agreement with Singapore-based commodity company Trafigura from NovaSAF-1 earlier this year.

Texas Gov. Abbott seeks data center crackdown as state grapples with growing power demand

growing pains

Just seven months ago, Gov. Greg Abbott trumpeted Google’s $40 billion plan to add three data center campuses in Texas. Now, amid growing public outcry over such projects, Abbott is pushing for a regulatory crackdown on data centers in the Lone Star State.

Abbott recently sent a letter to leaders of the Public Utility Commission of Texas (PUC) and the Electric Reliability Council of Texas (ERCOT) proposing stricter oversight of the state’s data centers. Texas is home to more than 400 data centers, with many more on the way, and is poised to become the world’s largest data center market.

Among other things, Abbott wants to:

  • Ensure residential electric bills go down — not up — as data centers connect to ERCOT’s grid, which supplies power for about 90 percent of Texans.
  • Require data centers to cover the costs of upgrades to deliver electricity to the power-hungry facilities.
  • Repeal sales tax exemptions and other “outdated or unnecessary” financial incentives for data centers.
  • Institute “best practices,” such as property setbacks and noise-reduction technology, to ease the impact of data centers on nearby residents.
  • Demand that all new data centers, which use a tremendous amount of water, be built with water-efficient technology.
  • Require large data centers to generate annual reports on their use of electricity and water.

Abbott has set a July 17 deadline for the PUC and ERCOT to address his recommendations.

“As Texas continues to welcome innovation and investment, we must ensure that growth strengthens our people and their quality of life without placing undue burdens on Texans and local communities,” Abbott wrote.

Abbott’s call for tighter control of data centers has elicited both praise and skepticism.

In a social media post on X, Texas House Speaker Dustin Burrows, a Lubbock Republican, thanked Abbott for seeking “accountability and reform” in the state’s data center industry. Burrows has made data centers one of his priority issues for the 2027 state legislative session.

State oil and gas regulator Wayne Christian, a member of the Texas Railroad Commission, weighed in with similarly positive comments about Abbott’s directive. He says an outright ban on data centers isn’t the answer to residents’ complaints about new facilities.

“The Texas way is not to answer innovation with government overreach or fear-driven bans,” Christian, whose agency wasn’t cited in Abbott’s letter, said in a statement posted on X. “Our job is to protect prosperity, safeguard taxpayers and ensure the infrastructure that powers our economy remains strong and reliable.”

Gina Hinojosa, an Austin Democrat who’s challenging Abbott in this November’s gubernatorial race, took issue with the governor’s edict on data centers.

“Greg Abbott is changing his tune on data centers because he knows his policies are unpopular,” Hinojosa, a state representative, wrote on X. “Nobody believes the arsonist is gonna be the one to put out the fire.”

Abbott’s call for stepped-up regulation of data centers echoes many of the concerns expressed by the state chapter of the Sierra Club, an environmental nonprofit.

“The growth of data centers reflects a broader transformation taking place across Texas,” the Sierra Club says on its website. “The state is becoming a hub for the technologies that will shape the future economy, from artificial intelligence to advanced computing and cloud services. At the same time, Texans deserve transparency about how these projects affect the communities where they are built.”
