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.

The company was founded in 2018 by Divyaditya Shrivastava and participated in the Y Combinator accelerator that year. The company raised a $5.2 million seed round in 2024 and another round for an undisclosed amount earlier this year. In the future, it plans to expand its DFR deployments into more cities, offer new payload delivery capabilities (like delivering Narcan and life vests), and enhance deconfliction features.

Persona AI

Persona AI is building modularized humanoid robots that aim to deliver continuous, round-the-clock productivity and skilled labor for "dull, dirty, dangerous, and declining" jobs.

Houston has the lowest inflation problem in the U.S., new study finds

Money Talk

Despite the national inflation rate sitting at 3 percent as of September 2025, the impact of inflation on Houston and the surrounding area isn't as severe as the rest of the U.S., a new study has revealed.

Houston-The Woodlands-Sugar Land ranked as the metro with the smallest inflation problem in the U.S. in WalletHub's October 2025 "Changes in Inflation by City" report.

The study tracked inflation changes for 23 major metropolitan statistical areas (MSAs) using Consumer Price Index data from the latest month available and compared to data from two months prior. The analysis also factored in inflation data from last year to analyze both short- and long-term inflation changes.

Compared to two months ago, the inflation rate in Houston fell by 0.1 percent, and local inflation is only 1.10 percent higher than it was a year ago, WalletHub said.

Houston residents may be feeling the sting a lot less than they did in January 2024, when WalletHub said the city had the 7th highest inflation rate in the country. And yet, Houstonians are increasingly concerned with the economy and its effects on inflation, a recent University of Houston survey found.

A separate WalletHub study named Texas the No. 1 most "financially distressed" state in the U.S. for 2025, adding to the severity of Texans' economical woes.

U.S. cities with the worst inflation problems

Denver-Aurora-Lakewood, Colorado topped the list as the city with the No. 1 worst inflation problem as of September. The Denver metro saw a 1 percent uptick in inflation when compared to two months prior, and it's 3.10 percent higher than it was a year ago.

Elsewhere in Texas, WalletHub ranked Dallas-Fort Worth-Arlington as the metro with the 8th lowest inflation problem nationwide. That's a fair shift from a previous report from June 2025 that ranked DFW the No. 1 U.S. metro with the lowest inflation issues.

The top 10 metros where inflation has risen the most as of September 2025 are:

  • No. 1 – Denver-Aurora-Lakewood, Colorado
  • No. 2 – Los Angeles-Long Beach-Anaheim, California
  • No. 3 – Chicago-Naperville-Elgin, Illinois-Indiana-Wisconsin
  • No. 4 – Boston-Cambridge-Newton, Massachusetts-New Hampshire
  • No. 5 –Minneapolis-St. Paul-Bloomington, Minnesota-Wisconsin
  • No. 6 – (tied) Philadelphia-Camden-Wilmington, Pennsylvania-New Jersey-Delaware-Maryland and Washington-Arlington-Alexandria, D.C.-Virginia-Maryland-West Virginia
  • No. 8 – Anchorage, Alaska
  • No. 9 – New York-Newark-Jersey City, New York-New Jersey-Pennsylvania
  • No. 10 – San Diego-Carlsbad, California

Axiom Space taps solar array developer for first space station module

space contract

Houston-based Axiom Space is making progress on developing its commercial space station.

The company awarded Florida-based Redwire Corporation a contract to develop and deliver roll-out solar array (ROSA) wings to power the Axiom Payload Power Thermal Module (AxPPTM), which will be the first module for the new space station.

AxPPTM will initially attach to the International Space Station. AxPPTM will later separate from the ISS and rendezvous with Axiom’s Habitat 1 (AxH1) on orbit. Eventually, an airlock, Habitat 2 (AxH2) and finally the Research and Manufacturing Facility (AxRMF) will be added to the first two Axiom modules.

AxPPTM is anticipated to launch toward the end of 2027. The two-module station (AxPPTM and AxH1) is expected to be operational as a free-flying station by 2028, and the full four-module station around 2030.

The modules will be integrated and assembled at Axiom Space’s Assembly and Integration facility, making them the first human-rated spacecraft built in Houston.

Redwire’s ROSA technology was originally developed for the ISS, according to Space News. It has yielded a 100 percent success rate on on-orbit performance. The technology has also been used on NASA’s Double Asteroid Redirection Test mission, the Maxar-built Power and Propulsion Element for the Artemis Lunar Gateway and Thales Alenia Space’s Space Inspire satellites.

“As a market leader for space power solutions, Redwire is proud to be selected as a strategic supplier to deliver ROSAs for Axiom Space’s first space station module,” Mike Gold, Redwire president of civil and international space, said in a news release. “As NASA and industry take the next steps to build out commercial space stations to maintain U.S. leadership in low-Earth orbit, Redwire continues to be the partner of choice, enabling critical capabilities to ensure on-orbit success.”
