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.

Axiom Space tops $525M in oversubscribed round, announces Swiss subsidiary

funding boost

Axiom Space tacked on an additional $175 million to a previously announced capital raise, bringing the oversubscribed round to a total of more than $525 million.

Axiom shared in February that it had secured $350 million in a financing round led by Type One Ventures and Qatar Investment Authority. In the latest release from the company, Axiom reports that Japan-based MUFG Bank Ltd. joined the round as a new investor, in addition to continued participation from existing backers.

The funding will go toward developing the company's commercial space station, known as Axiom Station, and the production of its Axiom Extravehicular Mobility Unit (AxEMU) under its NASA spacesuit contract.

“Investor interest in this round outpaced what we set out to raise, which speaks to the moment we’re in,” Jonathan Cirtain, CEO and president of Axiom Space, said in the news release. “Our partners see what is possible in low-Earth orbit, and they see who is positioned to lead it.”

Axiom announced last month that it planned to open a Japanese subsidiary July 1. Earlier this week, it also shared plans to establish Axiom Space Switzerland, a wholly owned subsidiary based in Lucerne that is also expected to begin operations this summer.

The Switzerland subsidiary aims to establish Axiom's presence in Europe and help it partner with the European Space Agency and other space organizations and companies on the continent.

“Europe is a founding leader in the creation of the commercial space economy, and Switzerland is uniquely positioned to convene the government agencies, research institutions, and industrial entities that will shape its next decade,” Cirtain added in a separate release. “Axiom Space Switzerland facilitates the scaling of development and deployment of the infrastructure that will succeed the International Space Station.”

Texas cashes in among 10 best U.S. state economies in 2026 report

State Economics

A new study gauging the success or decline in economic performance in every state has revealed Texas' economy remains stable in 2026 after it dropped out of the top five to No. 8 last year.

Texas boasts the No. 8 best state economy in the U.S. this year, according to WalletHub's annual "Best & Worst State Economies" report. The personal finance website's analysts ranked all 50 states and the District of Columbia across 28 relevant metrics to measure each state's economic activity and health status, and its "innovation potential."

Notably, Texas leads the nation for the most exports per capita in the U.S. in a five-way tie with Louisiana, Kentucky, North Dakota, and Indiana. Across the study's three main categories, Texas ranked highly for its economic activity (No. 7) and economic health (No. 11), and the state's "innovation potential" rank is the 24th best in the nation.

This is how WalletHub ranked Texas' economic performance, where No. 1 is considered the best and No. 25 is considered average:
  • No. 6 – Change in non-farm payrolls
  • No. 8 – Change in GDP
  • No. 8 – Startup activity
  • No. 11 – Annual median household income
  • No. 18 – Government surplus/deficit per capita
  • No. 21 – Percentage of jobs in high-tech industries
  • No. 30 – Unemployment rate
WalletHub previously ranked Texas one of the top three states to start a business in 2026, with Houston earning its own entrepreneurial acclaim in separate rankings of the best big cities for new businesses and for starting a career.

"U.S. economic growth depends heavily on the performance of individual states, and some contribute more than others," the report's author wrote. "For example, California, Texas, New York and Florida have economies so large that if they were countries, they would rank in the top 20 in the world."

The five states with the worst state economies in 2026 are Rhode Island (No. 47), Maine (No. 48), Louisana (No. 49), Kentucky (No. 50), and West Virginia (No. 51).

The top 10 best state economies for 2026 are:

  • No. 1 – Massachusetts
  • No. 2 – Washington
  • No. 3 – Utah
  • No. 4 – California
  • No. 5 – Delaware
  • No. 6 – North Carolina
  • No. 7 – New York
  • No. 8 – Texas
  • No. 9 – Colorado
  • No. 10 – Florida

Houston lab explores how AI bots can help the elderly

AI for aging

The University of Houston’s Empathetic Lifespan AI & Robotics for Aging (ELARA) Lab is currently conducting research into how AI bots may be able to help the elderly live more social and independent lives through several ongoing initiatives.

The lab officially launched last month as part of the Gerald D. Hines College of Architecture & Design under the leadership of Assistant Professor Chorong Park. Part of the lab’s mission is tackling ongoing problems with aging, such as dealing with disabilities and social isolation. Researchers’ current work is focused on designing a new AI companion bot specifically tailored to the needs of older people.

“We need to take all the needs of older adults seriously,” Park said in a news release. “They won't use the robot if they don't feel at ease or if they feel they are being constantly watched.”

The field testing of new AI bots in this population hopes to overcome several traditional obstacles in technology use among the elderly. A study by Park shows that many older people have a fear of overt surveillance when using advanced AI. There is also ageism to consider. Most new technologies are designed with younger and employed buyers in mind, not retirees who may need help remembering daily tasks or accessing important information.

“The more older adults are excluded from technology development, the worse those technology gaps will become,” Park said. “AI and the majority of technologies are created for younger people, so my research method integrates older adults directly into the design process.”

ELARA recently collaborated with the Mamie George Community Center in Richmond, Texas, to track seniors’ response to desktop AI bots like Emo and Cupboo. Researchers also had participants use air-dry modeling clay to create their ideal robotic companion.

While the eventual AI bot may be able to help the elderly feel less isolated and more supported, there are concerns to consider. A study published in the Asian Journal of Psychology charted the development of delusional thinking in a 72-year-old woman who became convinced the empathic-response bot was in love with her. The rise of “AI psychosis” has the potential to exacerbate mental health problems, particularly in socially isolated people, which a quarter of Americans over the age of 65 are.

ELARA’s research is focused on creating “pet-like” AI models with enhanced trust cues. If it can overcome the dangers of socially isolated people relying on AI for companionship, it could be a big step forward for independent aging.
