Houston-based clean energy company Syzygy Plasmonics has successfully tested all-electric CO2-to-fuel production technology at RTI International’s facility at North Carolina’s Research Triangle Park.

Syzygy says the technology can significantly decarbonize transportation by converting two potent greenhouse gases, carbon dioxide and methane, into low-carbon jet fuel, diesel, and gasoline.

Equinor Ventures and Sumitomo Corp. of Americas sponsored the pilot project.

“This project showcases our ability to fight climate change by converting harmful greenhouse gases into fuel,” Trevor Best, CEO of Syzygy, says in a news release.

“At scale,” he adds, “we’re talking about significantly reducing and potentially eliminating the carbon intensity of shipping, trucking, and aviation. This is a major step toward quickly and cost effectively cutting emissions from the heavy-duty transport sector.”

At commercial scale, a typical Syzygy plant will consume nearly 200,000 tons of CO2 per year, the equivalent of taking 45,000 cars off the road.

“The results of this demonstration are encouraging and represent an important milestone in our collaboration with Syzygy,” says Sameer Parvathikar, director of renewable energy and energy storage at RTI.

In addition to the CO2-to-fuel demonstration, Syzygy's Ammonia e-Cracking™ technology has completed over 2,000 hours of performance and optimization testing at its plant in Houston. Syzygy is finalizing a site and partners for a commercial CO2-to-fuel plant.

Syzygy is working to decarbonize the chemical industry, responsible for almost 20 percent of industrial CO2 emissions, by using light instead of combustion to drive chemical reactions.

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.

Houston startup teams up with nonprofit research for decarbonization pilot

seeing green

A Houston tech company has joined forces with a nonprofit to test a new sustainable fuel production process.

The project is a joint effort from Houston-based Syzygy Plasmonics and nonprofit research institute RTI International and sponsored by Equinor Ventures and Sumitomo Corporation of Americas. Based in the RTI facility in Research Triangle Park, North Carolina, the six-month pilot is testing a way to convert two potent greenhouse gases — carbon dioxide (CO2) and methane (CH4) — into low-carbon-intensity fuels, which have the potential to replace petroleum-based jet fuel, diesel, and gasoline.

"This demonstration will be the first of its kind and represents a disruptive step in carbon utilization. The sustainable fuels produced are expected to quickly achieve cost parity with today's fossil fuels," says Syzygy CEO Trevor Best in a news release. "Integrating our technology with RTI's Fischer-Tropsch synthesis system has the potential to significantly reduce the carbon intensity of shipping, trucking, and aviation without requiring major fleet modifications."

According to Syzygy, the pilot is a step toward being able to scale the process to a commercial-ready Syzygy e-fuels plant.

"By making minor adjustments in the process, we also expect to produce sustainable methanol using the same technology," Best continues.

An independent research institute, RTI International's focus is on improving the human condition. The multidisciplinary nonprofit seeks to support science-based solutions like Syzygy's technology, which has already proven its scale-up capabilities in earlier testing.

Through the partnership, RTI will assist Syzygy with process design and systems integration for the pilot-scale demonstration. Once it reaches commercial scale, the technology is expected to turn millions of tons of CO2 per year to produce sustainable fuels.

"We are excited about the opportunity to collaborate with Syzygy to test and assist in the scale-up of this promising technology," says Sameer Parvathikar, Ph.D., the director of the Renewable Energy and Energy Storage program in RTI's Technology Advancement and Commercialization business unit. "This work aligns with our capabilities, our goals of helping de-risk and commercialize novel technologies, and our vision to address the world's most critical problems with science-based solutions."

Houston EV charging tech company raises $6M series A

money moves

Houston-based tech company Revterra Corp. has picked up $6 million in a 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.

Revterra says its kinetic flywheel battery enables quick, simple, cost-effective installation of high-powered DC chargers for electric vehicles. The technology eases the burden placed on electrical grids, the company says.

“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.”

Jawdat earned a doctoral degree from the University of Houston, and he completed postdoctoral studies at Rice University and the Air Force Research Laboratory.

Revterra says its battery lasts eight times longer than traditional chemical batteries for EV charging do, supplies four times the power output, and causes less of an environmental impact.

“Revterra’s differentiated energy storage systems will be key to enabling fast charging capabilities for EVs and improving the resiliency of the power grid,” says Hossam Elbadawy, managing director of SCF Ventures. “A successful energy transition needs effective energy storage, and innovative technologies like Revterra’s flywheel will provide an important part of the answer.”

In 2021, Revterra joined Greentown Labs in Houston. The five-year-old startup says it plans to expand its workforce over the next 12 months, filling positions in areas such as electrical, mechanical, and manufacturing engineering. Some of those employees will be involved in building Revterra’s first assembly facility, which will be located in Houston.

Revterra plans to roll out its first full-size, commercial-ready batteries in 2023. The batteries are being designed to let an EV driver recharge a car’s battery in 15 minutes or less without taxing the existing electrical grid.

Houston alternative energy startup raises $23M series B with global support

money moves

A Houston startup founded based off research coming out of Rice University has closed its series B funding, the company announced this week.

Founded in 2017, Syzygy Plasmonics is a chemical company developing a photocatalyst-powered hydrogen fuel cell technology that produces a cheaper source of energy that releases fewer carbon emissions. As of this week, the company has $23 million more to fund its scaling and grow its team thanks to the closing of its series B financing led by Hong Kong-based Horizons Venture. Equinor Ventures, a new investor, also joined in on the round, along with previous seed and series A investors including The Engine, GOOSE Capital, and Evok Innovations.

"With renewable electricity as an energy source, our technology is cleaner, and because of the stability and activity of our photocatalysts, we can drive dozens of possibilities, tuning reactions that produce different chemicals," says Trevor Best, Syzygy Plasmonics' co-founder and CEO, in a news release. "Our initial product will focus on eliminating emissions from hydrogen production, transforming the industrial process involved in making semiconductors, LEDs and metals. Our system will also enable industries that are consumers of hydrogen fuel cells, like fuel cell vehicles."

The hydrogen-fueled technology originated out of research done over two decades by two Rice University professors, Naomi Halas and Peter Nordlander and further developed by the company's co-founder and CTO, Suman Khatiwada. The technology has the ability to both lower costs and emissions at industrial plants. According to the release, Syzygy's first product focused on hydrogen and the technology has the potential to cut the cost of zero emission hydrogen in half, when compared to other alternatives such as electrolysis.

"There are rules in chemical engineering, and you can't break them, but we follow them in a different way," CEO Trevor Best previously told InnovationMap. "What we're doing is fundamentally different. We're using light instead of heat to drive chemical reactions."

Currently, Syzygy employs 26 people and plans to double its workforce in the next year in order to launch its first full-size, commercial-ready chemical reactors in 2022.

In August of 2019, Syzygy raised its $5.8 million series A and secured Department of Energy ARPA-E and National Science Foundation SBIR Program grants.

"The keys to unlock the potential of hydrogen energy lie within production cost reduction and safety enhancements. Syzygy uses a photocatalysis process to produce H2 on premises, therefore mitigating risks of explosion imposed by the transportation of liquid hydrogen while lowering production costs to increase overall energy efficiency. This technology will be applicable to a wide-range of use-cases, enabling a faster path toward zero-emissions," says Patrick Poon of Horizons Ventures, who is also a new board member at Syzygy.

The international fundraise also attracted interest from Norway-based Equinor's venture arm, which has operations in more than 30 countries.

"We have announced our ambition to become a net-zero energy company by 2050 and in order for society at large to meet its climate goals it will require new solutions and technologies. We are pleased to announce the investment in Syzygy as one potential contributor to help the energy industry reduce emissions as part of our effort to shape the future of energy," says Gareth Burns, head of Equinor Ventures, in the release.

Houston ranks among 15 U.S. hot spots for women in tech

Ranking It

Houston is soaring among the best places in the U.S. for women in tech, a new report says. Houston ranked No. 15 nationwide in SmartAsset's new report, "Best and Worst Cities for Women in Tech — 2026 Study," which compared the 50 biggest U.S. cities across four metrics:

  • Gender pay gap — women's median earnings as a percentage of men’s median earnings in tech
  • The share of all tech workers that are women
  • The overall concentration of employment for tech workers, defined as "tech workers as a share of the local workforce"
  • Women tech workers’ median earnings, adjusted for regional price parity
For the purpose of the study, tech workers are defined as "city residents employed in computer and mathematical occupations." The study's findings show that fewer than 9,500 tech workers in Houston are women, or 25.6 percent of the total tech workforce in the city. In total, tech workers in general make up less than 3 percent of the Houston workforce.Despite the high ranking, women tech workers in Houston have a sizeable gap to cross to receive equal pay compared to their male counterparts in the same industry. Women tech workers make just over $97,000 in median earnings after adjusting for regional price parity, which is only 93 percent of what male tech workers make, SmartAsset found.

There are only two U.S. cities where women in tech earn more than what their male counterparts: Miami and Memphis, Tennessee. Women tech workers in Miami make an adjusted $88,650 in median earnings, or 101.7 percent of what men in tech make. In Memphis, women make $84,718 in adjusted earnings, or 101.5 percent of what men in tech earn.

The findings also assert that women remain underrepresented in the nation's overall tech sector, despite making up nearly half of the total workforce. Only 22.6 percent of the country's tech labor force is made up of women, according to the Equal Employment Opportunity Commission."Opportunities for women in tech can vary considerably by location, and these differences shape access to jobs, career advancement and earning potential," the report's author wrote. "In some places, women account for a larger share of tech workers, face narrower pay gaps and enjoy a stronger local labor market. In others, they may encounter a more challenging career environmentThe six other Texas cities that earned spots in the report are Austin (No. 6), Fort Worth (No. 26), Dallas (No. 32), Arlington (No. 38), San Antonio (No. 42), and El Paso (No. 49).

The top 10 best U.S. cities for women in tech are:

  • No. 1 – San Jose, California
  • No. 2 – Seattle, Washington
  • No. 3 – San Francisco, California
  • No. 4 – Atlanta, Georgia
  • No. 5 – Baltimore, Maryland
  • No. 6 – Austin, Texas
  • No. 7 – Oakland, California
  • No. 8 – Portland, Oregon
  • No. 9 – Boston, Massachusetts
  • No. 10 – Minneapolis, Minnesota
