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."

How Texas is on the road to becoming a prime state for EVs, according to this expert

guest column

As Texans adopt electric vehicles, significant strides must be made to ensure public charging meets demand. Steps are being made under the National Electric Vehicle Infrastructure Formula Program to address such needs. With new developments promising to bolster the state's infrastructure, it’s only a matter of time until all EV owners will have access to reliable and fast charging options.

NEVI Funding in Texas

Texans will benefit from NEVI funding. This federal initiative is part of a broader effort to enhance EV adoption by providing drivers with a robust and reliable network of fast chargers, particularly along corridors, i.e., highways between Houston, Dallas, Austin, San Antonio, etc. To date, Texas has been busy installing 66 fast-charging ports along those key corridors with much more to come (Electrify News Site). There are multiple phases associated with NEVI, and the first 50 sites outlined by the Texas Electric Vehicle Infrastructure Plan have been completed.

Enhanced Accessibility and Convenience

One of the key aspects of the NEVI-funded stations is their strategic placement in areas previously underserved by existing charging networks. This focus not only addresses range anxiety but also ensures a minimum of four chargers per site with a reliability standard of 97 percent uptime. Such strategic deployment is crucial for supporting the widespread use of electric vehicles, especially in a state as vast as Texas (Electrify News Site).

NACS Compatibility and Adapters: Bridging the Gap

To further support all EV drivers, Tesla has opened their previously closed charging network. This network’s charging system is known as the North American Charging Standard, or NACS. This will allow for other brands to leverage the largest and most reliable charging network in Texas and beyond. Now, just about every manufacturer has opted in to the NACS charging ecosystem. This standard will undoubtedly result in more coverage for all EV drivers and a true standard for the industry. You can see the list of manufacturers that have adopted NACS thus far here.

If you already drive a non-Tesla EV, don’t worry. Many manufacturers have embarked upon developing an adapter for you such as Ford. If you drive a Tesla, your options will remain more or less the same. You’ll not need an adapter with future fast charging stations.

At the end of 2023, there were roughly 19,000 Tesla Superchargers and 15,000 from the entirety of the charging community. Tesla aims to add another 7,500 by the end of 2024 in addition to $7.5B from the federal government to support all other charging initiatives.

This move is particularly beneficial for Texas, where the distances between charging stations can be vast. By enabling access to Tesla's superchargers, drivers can embark on long road trips with the assurance that a fast and reliable charging option is never far away. This increased accessibility will likely spur greater EV adoption, as drivers gain confidence in the state's charging infrastructure.

Charging at Home

The concept of fueling and charging EVs at home offers an exciting paradigm shift. Drivers often have to wait for their cars to approach Empty “E” on their dashboard. Some take it all the way down to the red line (or below) while others begin searching for gas stations once they’ve reached a quarter tank.

With EVs however, the average Houstonian who drives ~30 miles a day now has the potential to begin their day with a full charge. Those who have access to home charging can plug their cars in when they get home from work and typically make up for their daily driving/commute with a standard power outlet which offers a customer anywhere from 30-40 miles of charger over a 12 hour period.

But let’s say you’re a super commuter - someone who drives 75 miles a day or more! Starting off with a full charge every day is almost a necessity, and a standard power outlet may not cut it. Luckily, Level 2 chargers exist and serve as an incredible time and money saver. Like the average commuter, a super commuter can simply plug in a level 2 charger, and the EV will be back to full by the time they wake the next morning (offering anywhere from 20-30 miles of charge per hour). Even those who drive 150+ miles a day can confidently use their EVs as a daily driver if they have a Level 2 charger at home.

Embracing the Future

As we look to the future of transport and energy, the synergy between NEVI and Tesla’s network should create a compelling narrative for those thinking about leasing an EV. Combine that with exciting new battery tech and potential range improvements, fueled by West Texas wind and solar, Texas is positioned to be a great state for the EV industry.

Mayor announces major effort to reduce emissions on Houston's roadways

Easy EVs

The city of Houston has taken a major step toward reducing carbon emissions caused by its estimated 1.3 million vehicles that drive the city's streets daily.

Mayor Sylvester Turner announced a new partnership between the government, local businesses, and academic leaders that has created EVolve Houston. The coalition is aimed at boosting electric vehicle sales to 30 percent of new car sales in Houston by 2030.

"This new partnership will help solidify Houston's success as a leader in transportation technology and it will help improve air quality for the citizens of Houston and beyond, by reducing reliance on vehicles powered by carbon-based fuels," Mayor Turner says in a release. "Houston will now have a dedicated resource working to increase the adoption of electric vehicles, wherever it makes sense to do so. Nearly half of the greenhouse gas emissions in Houston come from transportation. Shifting to zero emission forms of transportation is a key strategy to help us meet our ambitious climate goals and improve our regional air quality."

EVolve Houston, which will contribute to the city's Climate Action Plan that was announced in July, will focus on increasing awareness, affordability, and availability of electric vehicles. The coalition's founding partners include the city, CenterPoint Energy, the University of Houston, NRG Energy, Shell, and LDR.

"Houston has bold goals to improve air quality and reduce greenhouse gas emissions. To do that, we must make a major impact on one of the largest sources of emissions, which is transportation" says Dr. Ramanan Krishnamoorti, the chief energy officer at University of Houston.

The partners will focus on launching pilot projects as well as hosting demonstrations and awareness activities to promote EV adoption, according to the release.

"At CenterPoint Energy, we are committed to making a positive difference in the communities we touch, and environmental stewardship is an integral component of our overall corporate responsibility approach," says Scott Prochazka, president and CEO of CenterPoint Energy, in the release. "I am proud to partner with Mayor Turner and other founding members of EVolve Houston to help accelerate clean transportation for Houston."

Baylor scientist lands $2M grant to explore links between viruses and Alzheimer’s

Alzheimer’s research

A Baylor College of Medicine scientist will begin exploring the possible link between Alzheimer’s disease and viral infections thanks to a $2 million grant awarded in March.

Dr. Ryan S. Dhindsa is an assistant professor of pathology & immunology at Baylor and a principal investigator at Texas Children’s Duncan Neurological Research Institute (Duncan NRI). He hypothesizes that Alzheimer’s may have some link to previous viral infections contracted by the patient. To study this intriguing possibility, the American Brain Foundation has gifted him the Cure One, Cure Many award in neuroinflammation.

“It is an honor to receive this support from the Cure One, Cure Many Award. Viral infections are emerging as a major, underappreciated driver of Alzheimer's disease, and this award will allow our team to conduct the most comprehensive screen of viral exposures and host genetics in Alzheimer's to date, spanning over a million individuals,” Dhindsa said in a news release. “Our goal is to identify which viruses matter most, why some people are more vulnerable than others, and ultimately move the field closer to new therapeutic strategies for patients.”

Roughly 150 million people worldwide will suffer from Alzheimer’s by 2050, making it the most common cause of dementia in the world. Despite this, scientists are still at a loss as to what exactly causes it.

Dhindsa’s research is part of a new range of theories that certain viral infections may trigger Alzheimer’s. His team will take a two-fold approach. First, they will analyze the medical records of more than a million individuals looking for patterns. Second, they will analyze viral DNA in stem cell-derived brain cells to see how the infections could contribute to neurological decay. The scale of the genomic data gathering is unprecedented and may highlight a link that traditional studies have missed.

Also joining the project are Dr. Caleb Lareau of Memorial Sloan Kettering Cancer Center and Dr. Artem Babaian of the University of Toronto. Should a link be found, it would open the door to using anti-virals to prevent or treat Alzheimer’s.

Tesla Robotaxi service officially launches in Houston and Dallas

Future of the Roads

Tesla’s Robotaxi service has taken to the streets of Houston. In a brief statement Saturday, April 18 on its X social media account, Tesla Robotaxi says the autonomous rideshare service just launched in Texas’ two biggest metro areas — Houston and Dallas.

“Try Tesla Robotaxi in Dallas & Houston!” Tesla CEO Elon Musk says in a reposting on X of the Robotaxi announcement.

One of Robotaxi’s competitors, Alphabet-owned Waymo, beat the Tesla service to the Dallas, Houston, and Austin markets. Another competitor, Amazon-owned Zoox, has Dallas flagged for its autonomous rideshare service.

Robotaxi previously kicked off in Austin, where Tesla is based and manufactures electric vehicles, and the San Francisco Bay Area. Nearly 50 Robotaxis operate in Austin, where the service’s inaugural rides happened last year, and more than 500 in the San Francisco area.

Of the three rides logged in a 31-square-mile area in Dallas as of Monday morning, the average fare was $7.96 and the average trip was 3.5 miles, according to an online tracker of autonomous rideshare services. The tracker showed only one Robotaxi was on the roads in Dallas.

As of Monday morning, a 25-square-mile area in Houston had two Robotaxis on the road, according to the online tracker. The average fare for five recorded rides was $11.34 and the average trip was six miles.

“We want Robotaxi pricing to be simple and easy for you to understand,” according to the Robotaxi website. “Initially, as part of our introductory program, we will charge a simple, affordable rate plus applicable taxes and fees for all rides within the available service area.”

The tracker shows the Robotaxi in Dallas did not have a human aboard to monitor each trip, and only one of Houston’s two Robotaxis did not have a human monitor in the driver’s seat.

For now, all passengers ride in Tesla Model Y cars. Robotaxi operates from 6 am-2 am daily.

To use the service, you first must download the Robotaxi app, which works only on iPhones.

Robotaxi lets you stream music and adjust climate settings and seat positioning from the Robotaxi app or the vehicle’s touchscreen. Climate and media settings are stored in your Robotaxi profile and automatically transfer from one vehicle to another. If you own a Tesla, certain profile settings and media preferences are available in your own car as well as in a Robotaxi.

In January at the World Economic Forum in Davos, Switzerland, Musk said a “widespread” network of driverless rideshare vehicles would be operating in the U.S. by the end of this year, CNBC reported.

Houston VC funding surged nearly 50% in Q1 2026, report says

VC victories

First-quarter venture capital funding for Houston-area startups climbed nearly 50 percent compared to the same time last year, according to the PitchBook-NVCA Venture Monitor.

In Q1 2026, Houston-area startups raised $532.3 million, a 49 percent jump from $320.2 million in Q1 2025, according to the PitchBook-NVCA Venture Monitor.

However, the Q1 total fell 23 percent from the $671.05 million raised in Q4 2025.

Among the first-quarter funding highlights in Houston were:

  • Utility Global, which focuses on industrial decarbonization, announced a first close of $100 million for its Series D round.
  • Sage Geosystems raised a $97 million Series B round to support its geothermal energy storage technology.

Those funding rounds underscore Houston’s evolution as a magnet for VC in the energy sector.

“Today, the energy sector is increasingly extending into the startup economy as venture capital flows into companies developing the technologies that will shape the future of global energy,” the Greater Houston Partnership says.

The energy industry accounted for nearly 40 percent of Houston-area VC funding last year, according to market research and lead generation service Growth List.

Adding to Houston’s stature in VC for energy startups are investors like Chevron Technology Ventures, the investment arm of Houston-based oil and gas giant Chevron; Goose Capital; Mercury Fund; and Quantum Energy Partners.
