How this Houston innovator's tech is gearing up to impact EV charging, energy transition

houston innovators podcast episode 172

With more and more electric vehicles on the road, existing electrical grid infrastructure needs to be able to keep up. Houston-based Revterra has the technology to help.

"One of the challenges with electric vehicle adoption is we're going to need a lot of charging stations to quickly charge electric cars," Ben Jawdat, CEO and founder of Revterra, says on the Houston Innovators Podcast. "People are familiar with filling their gas tank in a few minutes, so an experience similar to that is what people are looking for."

To charge an EV in ten minutes is about 350 kilowatts of power, and, as Jawdat explains, if several of these charges are happening at the same time, it puts a tremendous strain on the electric grid. Building the infrastructure needed to support this type of charging would be a huge project, but Jawdat says he thought of a more turnkey solution.

Revterra created a kinetic energy storage system that enables rapid EV charging. The technology pulls from the grid, but at a slower, more manageable pace. Revterra's battery acts as an intermediary to store that energy until the consumer is ready to charge.

"It's an energy accumulator and a high-power energy discharger," Jawdat says, explaining that compared to an electrical chemical battery, which could be used to store energy for EVs, kinetic energy can be used more frequently and for faster charging.

Jawdat, who is a trained physicist with a PhD from the University of Houston and worked as a researcher at Rice University, says some of his challenges were receiving early funding and identifying customers willing to deploy his technology.

Last year, Revterra raised $8.5 million in a series A funding round. Norway’s Equinor Ventures led the round, with participation from Houston-based SCF Ventures and At One Ventures. Previously, Revterra raised nearly $500,000 through a combination of angel investments and a National Science Foundation grant.

The funding has gone toward growing Revterra's team, including onboarding three new engineers with some jobs still open, Jawdat says. Additionally, Revterra is building out its new lab space and launching new pilot programs.

Ultimately, Revterra, an inaugural member of Greentown Houston, hopes to be a major player within the energy transition.

"We really want to be an enabling technology in the renewable energy transition," Jawdat says. "One part of that is facilitating the development of large-scale, high-power, fast-charging networks. But, beyond that, we see this technology as a potential solution in other areas related to the clean energy transition."

He shares more about what's next for Revterra on the podcast. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Revterra Corp. has raised $6 million in its series A funding round to propel development of its battery for electric vehicle charging stations. Norway’s Equinor Ventures led the round, with participation from Houston-based SCF Ventures. Previously, Revterra raised nearly $500,000 through a combination of angel investments and a National Science Foundation grant.

“There is an urgent need to reduce carbon emissions globally,” physicist Ben Jawdat, founder and CEO of Revterra, says in a news release. “Our goal at Revterra is to deploy scalable energy storage solutions that facilitate the shift to renewables and EVs while hardening our electric grid. Our systems enable these ambitions while utilizing materials that are recyclable and based on a secure supply chain.” Click here to read more.

Necessity is the mother of invention — and Sam Sabbahi needed a better way to heat and cool common joint injuries. Sabbahi, a physical therapist by trade, wanted to optimize the traditional way of using ice or heat packs.

“In the field, we were always getting people coming in trying to get us to purchase different medical devices and we wondered, ‘who knows what we need better than we do?’” he says. “A patient asked me ‘what a cold pack does’ and I was thinking in my head that a cold pack just cools the skin to three millimeters depth.”

Sabbahi then developed and invented a portable convection-based heating and cooling system device that could be used for joint injury rehabilitation – the device, dubbed Thermocuff, works much in the way that an air fryer circulates the air to get an even temperature. Click here to read more.

Houston space tech company develops new engine features with NASA funding

testing 1, 2, 3

Outfitted with a new type of aerospace technology, a rocket engine developed by Houston startup Venus Aerospace for hypersonic flights will undergo testing this summer.

Supported by a $155,908 federal Small Business Innovation Research (SBIR) grant from NASA, Venus Aerospace came up with a new design for nozzles — engine parts that help manage power — for its compact rocket engine. Venus Aerospace says the newly configured nozzles have “exceeded expectations” and will be incorporated into Venus’ upcoming ground-based engine testing.

“We’ve already proven our engine outperforms traditional systems on both efficiency and size,” Venus Aerospace CEO Sassie Duggleby says. “The technology we developed with NASA’s support will now be part of our integrated engine platform — bringing us one step closer to proving that efficient, compact, and affordable hypersonic flight can be scaled.”

The engine at the heart of Venus’ flight platform is called a rotating detonation rocket engine (RDRE). Venus says it’s the first U.S. company to make a scalable, affordable, flight-ready RDRE.

Unlike conventional rocket engines, Venus’ RDRE operates through supersonic shockwaves, called detonations, that generate more power with less fuel.

“This is just the beginning of what can be achieved with Venus propulsion technology,” says Andrew Duggleby, chief technology officer at Venus, founded in 2020. “We’ve built a compact high-performance system that unlocks speed, range, and agility across aerospace, defense, and many other applications. And we’re confident in its readiness for flight.”

Last fall, the company unveiled a high-speed engine system that enables takeoff, acceleration, and hypersonic cruising — all powered by a single engine. While most high-speed systems require multiple engines to operate at different speeds, Venus’ innovation does away with the cost, weight and complexity of traditional propulsion technology.

Among other applications, the Venus system supports:

  • Spacecraft landers
  • Low-earth-orbit satellites
  • Vehicles that haul space cargo
  • Hypersonic drones and missiles

Nvidia announces plans to produce AI supercomputers at new Texas plants

Manufacturing News

Nvidia announced Monday that it will produce its artificial intelligence supercomputers in the United States for the first time.

The tech giant said it has commissioned more than 1 million square feet of manufacturing space to build and test its specialized Blackwell chips in Arizona and AI supercomputers in Texas — part of an investment the company said will produce up to half a trillion dollars of AI infrastructure in the next four years.

“The engines of the world’s AI infrastructure are being built in the United States for the first time,” Nvidia founder Jensen Huang said in a statement. “Adding American manufacturing helps us better meet the incredible and growing demand for AI chips and supercomputers, strengthens our supply chain and boosts our resiliency.”

Nvidia’s announcement comes as the Trump administration has said that tariff exemptions on electronics like smartphones and laptops are only a temporary reprieve until officials develop a new tariff approach specific to the semiconductor industry.

White House officials, including President Donald Trump himself, spent Sunday downplaying the significance of exemptions that lessen but won’t eliminate the effect of U.S. tariffs on imports of popular consumer devices and their key components.

“They’re exempt from the reciprocal tariffs but they’re included in the semiconductor tariffs, which are coming in probably a month or two,” U.S. Commerce Secretary Howard Lutnick told ABC’s “This Week” on Sunday.

Nvidia said in a post on its website that it has started Blackwell production at Taiwan Semiconductor Manufacturing Co. chip plants in Phoenix. The Santa Clara, California-based chip company is also building supercomputer manufacturing plants in Texas — with Foxconn in Houston and Wistron in Dallas.

Nvidia's AI super computers will serve as the engines for AI factories, “a new type of data center created for the sole purpose of processing artificial intelligence,” the company said, adding that manufacturing in the U.S. will create “hundreds of thousands of jobs and drive trillions of dollars in economic security over the coming decades."

Mass production at both plants is expected to ramp up in the next 12-15 months, Nvidia said. The company also plans on partnering with Taiwan-based company SPIL and Amkor for “packaging and testing operations” in Arizona.

In a statement Monday, the White House called Nvidia’s move “the Trump Effect in action.”

Trump “has made U.S.-based chips manufacturing a priority as part of his relentless pursuit of an American manufacturing renaissance, and it’s paying off — with trillions of dollars in new investments secured in the tech sector alone,” the White House said.

Earlier this year, Trump announced a joint venture investing up to $500 billion for infrastructure tied to artificial intelligence by a new partnership formed by OpenAI, Oracle and SoftBank. The new entity, Stargate, was tasked with building out data centers and the electricity generation needed for the further development of the fast-evolving AI in Texas, according to the White House.

The initial investment is expected to be $100 billion and could reach five times that sum.

Houston XR training company lands $5.8M contract with Air Force

taking flight

The U.S. Air Force’s AFWERX innovation arm has picked Houston-based HTX Labs to provide AI-enabled immersive training for workers who maintain Boeing KC-135 refueling tankers.

HTX Labs, an extended reality (XR) company and provider of immersive training programs for U.S. armed forces, will receive as much as $5.8 million in military funding for this project.

The new initiative comes on the heels of HTX Labs completing the second phase of a virtual KC-135 maintenance training program in partnership with Mildenhall, a Royal Air Force station in England. HTX Labs received Small Business Innovation Research (SBIR) funding for the second-phase project.

Under the new initiative, part of its EMPACT training platform, HTX Labs will develop a virtual AI-powered classroom for workers who maintain the KC-135’s F108 engine. In conjunction with this project, HTX Labs will collaborate with the Maine Air National Guard’s 101st Air Refueling Wing Maintenance Squadron on improving EMPACT.

Major Ryan Wing of the Maine Air National Guard says KC-135 maintenance workers “have limited opportunities to perform some of the more complex aircraft and engine repairs in a training environment. Providing immersive training to our warfighters is essential to ensuring mission readiness.”

In January, HTX Labs tapped Brian Reece as vice president of strategic accounts for the Air Force. In this role, he oversees HTX Labs’ relationship with this military branch. Reece is a retired Air Force colonel.

In 2022, Dallas-based Cypress Growth Capital invested $3.2 million in HTX Labs, which was founded in 2017.
