A Houston-based maritime technology company that is working to reduce emissions in the cargo and shipping industry has raised VC funding and opened a new Houston headquarters.

Fleetzero announced that it closed a $43 million Series A financing round this month led by Obvious Ventures with participation from Maersk Growth, Breakthrough Energy Ventures, 8090 Industries, Y Combinator, Shorewind, Benson Capital and others. The funding will go toward expanding manufacturing of its Leviathan hybrid and electric marine propulsion system, according to a news release.

The technology is optimized for high-energy and zero-emission operation of large vessels. It uses EV technology but is built for maritime environments and can be used on new or existing ships with hybrid or all-electric functions, according to Fleetzero's website. The propulsion system was retrofitted and tested on Fleetzero’s test ship, the Pacific Joule, and has been deployed globally on commercial vessels.

Fleetzero is also developing unmanned cargo vessel technology.

"Fleetzero is making robotic ships a reality today. The team is moving us from dirty, dangerous, and expensive to clean, safe, and cost-effective. It's like watching the future today," Andrew Beebe, managing director at Obvious Ventures, said in the news release. "We backed the team because they are mariners and engineers, know the industry deeply, and are scaling with real ships and customers, not just renderings."

Fleetzero also announced that it has opened a new manufacturing and research and development facility, which will serve as the company's new headquarters. The facility features a marine robotics and autonomy lab, a marine propulsion R&D center and a production line with a capacity of 300 megawatt-hours per year. The company reports that it plans to increase production to three gigawatt-hours per year over the next five years.

"Houston has the people who know how to build and operate big hardware–ships, rigs, refineries and power systems," Mike Carter, co-founder and COO of Fleetzero, added in the release. "We're pairing that industrial DNA with modern batteries, autonomy, and software to bring back shipbuilding to the U.S."

Hobby debuts solar canopy as airport system reaches new sustainability milestone

solar solutions

Houston's William P. Hobby Airport is generating its own clean energy.

Houston Airports announced that Hobby's red garage is now home to a "solar canopy" that is producing energy at 100 percent capacity to power daily operations. The photovoltaic (PV) solar system generated more than 1.1 gigawatt-hours of electricity in testing, and is expected to produce up to 1 megawatt-hour now that it's operating at full power.

“This project is proof that sustainability can be practical, visible and directly tied to the passenger experience,” Jim Szczesniak, director of aviation for Houston Airports, said in a news release. “Passengers now park under a structure that shields their cars from the Texas sun while generating clean energy that keeps airport operations running efficiently, lowering overall peak demand electrical costs during the day and our carbon footprint. It’s a win for travelers, the city and the planet.”

The project was completed by Texas A&M Engineering Experiment Station (TEES) and CenterPoint Energy. It's part of Houston Airport's efforts to reduce carbon emissions by 40 percent over its 2019 baseline.

In a separate announcement, the airport system also shared that it recently reached Level 3 in the Airports Council International (ACI) Airport Carbon Accreditation program after reducing emissions by 19 percent in three years. This includes reductions at George Bush Intercontinental Airport (IAH), Hobby and Ellington Airport/Houston Spaceport.

The reductions have come from initiatives such as adding electric vehicles to airport fleets, upgrading airfield lighting with LED bulbs, adding smarter power systems to terminals, and improving IAH's central utility plant with more efficient equipment. Additionally, the expansion to Hobby's West Concourse and renovations at IAH Terminal B incorporate cleaner equipment and technology.

According to Houston Airports, from 2019 to 2023:

  • IAH reduced emissions by 17 percent
  • Hobby reduced emissions by 32 percent
  • Ellington Airport reduced emissions by 4 percent

"I see firsthand how vital it is to link infrastructure with sustainability,” Houston City Council Member Twila Carter, chair of the council’s Resilience Committee, said in the release. “Reducing carbon emissions at our airports isn’t just about cleaner travel — it’s about smarter planning, safer communities and building a Houston that can thrive for generations to come.”

Chevron enters the lithium market with major Texas land acquisition

to market

Chevron U.S.A., a subsidiary of Houston-based energy company Chevron, has taken its first big step toward establishing a commercial-scale lithium business.

Chevron acquired leaseholds totaling about 125,000 acres in Northeast Texas and southwest Arkansas from TerraVolta Resources and East Texas Natural Resources. The acreage contains a high amount of lithium, which Chevron plans to extract from brines produced from the subsurface.

Lithium-ion batteries are used in an array of technologies, such as smartwatches, e-bikes, pacemakers, and batteries for electric vehicles, according to Chevron. The International Energy Agency estimates lithium demand could grow more than 400 percent by 2040.

“This acquisition represents a strategic investment to support energy manufacturing and expand U.S.-based critical mineral supplies,” Jeff Gustavson, president of Chevron New Energies, said in a news release. “Establishing domestic and resilient lithium supply chains is essential not only to maintaining U.S. energy leadership but also to meeting the growing demand from customers.”

Rania Yacoub, corporate business development manager at Chevron New Energies, said that amid heightening demand, lithium is “one of the world’s most sought-after natural resources.”

“Chevron is looking to help meet that demand and drive U.S. energy competitiveness by sourcing lithium domestically,” Yacoub said.

Musk says Tesla's robotaxis will roll out in Austin this month. Getty Images

Tesla's robotaxi service 'tentatively' to launch in Austin in June, Musk says

Tesla Talk

Elon Musk says Tesla is “tentatively” set to begin providing robotaxi service in Austin on June 22.

In a post on his X social media platform, Musk said the date could change because Tesla is “being super paranoid about safety.”

Investors, Wall Street analysts and Tesla enthusiasts have been anticipating the rollout of the driverless cabs since Musk said earlier this year that the service would launch in Austin sometime in June.

Last month, Musk told CNBC that the taxis will be remotely monitored at first and “geofenced” to certain areas of the city deemed the safest to navigate. He said he expected to initially run 10 or so taxis, increase that number rapidly and start offering the service in Los Angeles, San Antonio, San Francisco and other cities.

Musk has been promising fully autonomous, self-driving vehicles “next year” for a decade, but the pressure is on now as Tesla actually begins to operate a self-driving taxi service.

Sales of Tesla’s electric vehicles have sagged due to increased competition, the retooling of its most popular car, the Model Y, and the fallout from Musk’s turn to politics.

The Austin rollout also comes after Musk had a public blowup with President Donald Trump over the administration’s tax bill. Some analysts have expressed concern that Trump could retaliate by encouraging federal safety regulators to to step in at any sign of trouble for the robotaxis.

Houston innovator drives EV adoption with unique approach to car leasing, smart tech

HOUSTON INNOVATORS PODCAST EPISODE 258

Switching from a gas-powered car to an electric one can be a big change, but a Houston-based company has made things a lot easier for its customers.

Octopus Electric Vehicles US, a spinout of United Kingdom-based retail energy provider Octopus Energy, matches its users with their perfect EV lease and sets them up with smart electricity technology for at-home charging.

"We do a couple of really unique things that are not only first of its kind but really innovative," Octopus EV's US Co-Lead Chris George says on the Houston Innovators Podcast, pointing out specifically Octopus Energy's Intelligent Octopus, a smart feature for customers that automates energy usage to lower cost.

"We launched an Intelligent Octopus for EVs service. Instead of operating in a very narrow window — overnight — it operates dynamically," he continues.


Pulling from the success of its British EV leasing business, Octopus EV helps Texans find their ideal car to lease from the available pre-owned EVs in the state. The process is hands on, George says, and he and his team are constantly working directly with customers to find them their right make, model, mileage, and more, then setting them up for free home charging with Octopus. All this for as low as $200 a month — perfect for both EV veterans and newbies alike.

"We serve a lot of people. What we're aiming to do is to drive adoption, and we're finding that for most people this is their first EV," George says, explaining that accessibility has been an issue for aspiring EV owners.

The company is rolling out a new process this week. In addition to providing its service in a match-making capacity, now Octopus EV will be showcasing EVs so that customers can browse, test drive, and really get to see what all they like before deciding on a car. George says this new process will be a bit of an experiment.

"We're gong to be showcasing inventory around Houston so customers can see the physical car, the lease price, test drive, and get the car you want," George says. "It's going to look and feel a little different from our current product, but it's going to serve customers just the same."

On the show, George, who previously led EV adoption-focused nonprofit Evolve Houston, shares a bit about the EV industry and what he's closely watching, including growth of charging stations, multifamily charging opportunities, battery technology for EVs and resilience, and perfecting messaging for new and returning customers.

"I'm always trying to think about where are the other things where we can unlock innovation, unlock ideas that help our industry and help Houstonians," George says.

Houston scientists discover breakthrough process for lithium-ion battery recycling

future of EVs

With the rise of electric vehicles, every ounce of lithium in lithium-ion batteries is precious. A team of scientists from Rice University has figured out a way to retrieve as much as 50 percent of the material in used battery cathodes in as little as 30 seconds.

Researchers at Rice University’s Nanomaterials Laboratory led by Department of Materials Science and NanoEngineering Chair Pulickel Ajayan released the findings a new study published in Advanced Functional Materials. Their work shows that the process overcomes a “bottleneck” in lithium-ion battery recycling technology. The researchers described a “rapid, efficient and environmentally friendly method for selective lithium recovery using microwave radiation and a readily biodegradable solvent,” according to a news release.

Past recycling methods have involved harsh acids, and alternative eco-friendly solvents like deep eutectic solvents (DESs) at times have not been as efficient and economically viable. Current recycling methods recover less than 5 percent of lithium, which is due to contamination and loss during the process.

In order to leach other metals like cobalt or nickel, both the choline chloride and the ethylene glycol have to be involved in the process, according to the researchers at Rice. The researchers submerged the battery waste material in the solvent and blasted it with microwave radiation since they knew that of the two substances only choline chloride is good at absorbing microwaves.

Microwave-assisted heating can achieve similar efficiencies like traditional oil bath heating almost 100 times faster. Using the microwave-based process, Rice found that it took 15 minutes to leach 87 percent of the lithium, which differs from the 12 hours needed to obtain the same recovery rate via oil bath heating.

“This method not only enhances the recovery rate but also minimizes environmental impact, which makes it a promising step toward deploying DES-based recycling systems at scale for selective metal recovery,” Ajayan says in the release.

Due to rise in EV production, the lithium-ion battery global market is expected to grow by over 23 percent in the next eight years, and was previously valued at over $65 billion in 2023.

“We’ve seen a colossal growth in LIB use in recent years, which inevitably raises concerns as to the availability of critical metals like lithium, cobalt and nickel that are used in the cathodes,” the study's co-author, Sohini Bhattacharyya, adds. “It’s therefore really important to recycle spent LIBs to recover these metals.”

Houston clocks in as one of the hardest working cities in America

Ranking It

Houston and its residents are proving their tenacity as some of the hardest working Americans in 2026, so says a new study.

WalletHub's annual "Hardest-Working Cities in America (2026)" report ranked Houston the 37th most hardworking city nationwide. H-town last appeared as the 28th most industrious American city in 2025, but it still remains among the top 50.

The personal finance website evaluated 116 U.S. cities based on 11 key indicators across "direct" and "indirect" work factors, such as an individual's average workweek hours, average commute times, employment rates, and more.

The U.S. cities that comprised the top five include Cheyenne, Wyoming (No. 1); Anchorage, Alaska (No. 2); Washington, D.C. (No. 2); Sioux Falls, South Dakota (No. 4); and Irving, Texas (No. 5). Dallas and Austin also earned a spot among the top 10, landing as No. 7 and No. 10, respectively.

Based on the report's findings, Houston has the No. 31-best "direct work factors" ranking in the nation, which analyzed residents' average workweek hours, employment rates, the share of households where no adults work, the share of workers leaving vacation time unused, the share of "engaged" workers, and the rate of "idle youth" (residents aged 16-24 that are not in school nor have a job).

However, Houston lagged behind in the "indirect work factors" ranking, landing at No. 77 out of all 116 cities in the report. "Indirect" work factors that were considered include residents' average commute times, the share of workers with multiple jobs, the share of residents who participate in local groups or organizations, annual volunteer hours, and residents' average leisure time spent per day.

Based on data from The Organisation for Economic Co-operation and Development (OECD), WalletHub said the average American employee works hundreds of more hours than workers residing in "several other industrialized nations."

"The typical American puts in 1,796 hours per year – 179 more than in Japan, 284 more than in the U.K., and 465 more than in Germany," the report's author wrote. "In recent years, the rise of remote work has, in some cases, extended work hours even further."

WalletHub also tracked the nation's lowest and highest employment rates based on the largest city in each state from 2009 to 2024.

Other Texas cities that earned spots on the list include Fort Worth (No. 13), Corpus Christi (No. 14), Arlington (No. 15), Plano (No. 17), Laredo (No. 22), Garland (No. 24), El Paso (No. 43), Lubbock (No. 46), and San Antonio (No. 61).

Data for this study was sourced from the U.S. Census Bureau, Bureau of Labor Statistics, U.S. Travel Association, Gallup, Social Science Research Council, and the Corporation for National & Community Service as of January 29, 2026.

With boost from Houston, Texas is the No. 1 state for economic development

governor's cup

Texas is on a 14-year winning streak as the top state for attracting job-creating business location and expansion projects.

Once again, Texas has claimed Site Selection magazine’s Governor’s Cup. This year’s honor recognizes the state with the highest number of economic development projects in 2025. Texas landed more than 1,400 projects last year.

Ron Starner, executive vice president of Site Selection, calls Texas “a dynasty in economic development.”

Among metro areas, Houston lands at No. 2 for the most economic development projects secured last year (590), behind No. 1 Chicago and ahead of No. 3 Dallas-Fort Worth.

In praising Houston as a project magnet, Gov. Greg Abbott cites the November announcement by pharmaceutical giant Lilly that it’s building a $6.5 billion manufacturing plant at Houston’s Generation Park.

“Growth in the Greater Houston region is a great benefit to our state’s economy, a major location for foreign direct investment and key industry sectors like energy, aerospace, advanced manufacturing, and life sciences,” Abbott tells Site Selection. “Houston is also home to one of the largest concentrations of U.S. headquarters for companies from around the world.”

In 2025, Fortune ranked Houston as the U.S. city with the third-highest number of Fortune 500 headquarters (26).

Texas retained the Governor’s Cup by gaining over 1,400 business location and expansion projects last year, representing more than $75 billion in capital investments and producing more than 42,000 new jobs.

Site Selection says Texas’ project count for 2025 handily beat second-place Illinois (680 projects) and third-place Ohio (467 projects). Texas’ number for 2025 represented 18% of all qualifying U.S. projects tracked by Site Selection.

“You can see that we are on a trajectory to ensure our economic diversification is going to inoculate us in good times, as well as bad times, to ensure our economy is still going to grow, still create new jobs, prosperity, and opportunities for Texans going forward,” Abbott says.
