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 humanoid robotics startup inks new deal to deploy its rugged robots

big deal

Houston-based Persona AI announced the expansion of its operations at the Ion and a major milestone in deploying its humanoid robots.

The company will establish a state-of-the-art development center in the prominent corner suite on the first floor of the Ion, and is slated to begin expansion in June.

“We chose the Ion because it’s more than just a building — it’s a thriving innovation ecosystem,” CEO Nicolaus Radford said in a news release. “This is where Houston’s tech future is being built. It’s a convergence point for the people, energy, and ideas that power our mission to redefine human-machine collaboration. For an industrial, AI-driven robotics company, there’s no better place to scale than in the heart of Houston.”

Persona AI’s new development center will be located in the suite utilized by the Ion Prototyping Lab, managed by TXRX Labs. The IPL will transition its operations to the expanded TXRX facility in the East End Maker Hub, which will allow the lab to grow its team and meet increased demand.

At the start of the year, Persona AI closed $25 million in pre-seed funding. Earlier this month, the company announced a memorandum of understanding with HD Korea Shipbuilding & Offshore Engineering, HD Hyundai Robotic, and Korean manufacturing firm Vazil Company to create and deploy humanoid robots for complex welding tasks in shipyards.

The project will deliver prototype humanoids by the end of 2026, with field testing and full commercial deployment scheduled to begin in 2027.

"As heavy industry faces growing labor constraints—especially in high-risk trades like welding—the need for rugged, autonomous humanoid robots is more urgent than ever,” Radford added in a separate statement. “This partnership with HD Hyundai and Vazil is more than symbolic—deploying to the shipyard is one of the largest real-world proving grounds for Persona's tough, humanoid robots.”

Houston climatech co. to lead one of world's largest carbon capture projects

Big Deal

Houston-based CO2 utilization company HYCO1 has signed a memorandum of understanding with Malaysia LNG Sdn. Bhd., a subsidiary of Petronas, for a carbon capture project in Malaysia, which includes potential utilization and conversion of 1 million tons of carbon dioxide per year.

The project will be located in Bintulu in Sarawak, Malaysia, where Malaysia LNG is based, according to a news release. Malaysia LNG will supply HYCO1 with an initial 1 million tons per year of raw CO2 for 20 years starting no later than 2030. The CCU plant is expected to be completed by 2029.

"This is very exciting for all stakeholders, including HYCO1, MLNG, and Petronas, and will benefit all Malaysians," HYCO1 CEO Gregory Carr said in the release. "We approached Petronas and MLNG in the hopes of helping them solve their decarbonization needs, and we feel honored to collaborate with MLNG to meet their Net Zero Carbon Emissions by 2050.”

The project will convert CO2 into industrial-grade syngas (a versatile mixture of carbon monoxide and hydrogen) using HYCO1’s proprietary CUBE Technology. According to the company, its CUBE technology converts nearly 100 percent of CO2 feed at commercial scale.

“Our revolutionary process and catalyst are game changers in decarbonization because not only do we prevent CO2 from being emitted into the atmosphere, but we transform it into highly valuable and usable downstream products,” Carr added in the release.

As part of the MoU, the companies will conduct a feasibility study evaluating design alternatives to produce low-carbon syngas.

The companies say the project is expected to “become one of the largest CO2 utilization projects in history.”

HYCO1 also recently announced that it is providing syngas technology to UBE Corp.'s new EV electrolyte plant in New Orleans. Read more here.

Texas tops ranking of best states for investors in new report

by the numbers

Texas ranks third on a new list of the best states for investors and startups.

Investment platform BrokerChooser weighed five factors to come up with its ranking:

  • 2024 Google search volume for terms related to investing
  • Number of investors
  • Number of businesses receiving investments in 2024
  • Total amount of capital invested in businesses in 2024
  • Percentage change in amount of investment from 2019 to 2024

Based on those figures, provided mostly by Crunchbase, Texas sits at No. 3 on the list, behind No. 1 California and No. 2 New York.

Especially noteworthy for Texas is its investment total for 2024: more than $164.5 billion. From 2019 to 2024, the state saw a 440 percent jump in business investments, according to BrokerChooser. The same percentages are 204 percent for California and 396 percent for New York.

“There is definitely development and diversification in the American investment landscape, with impressive growth in areas that used to fly under the radar,” says Adam Nasli, head analyst at BrokerChooser.

According to Crunchbase, funding for Texas startups is off to a strong start in 2025. In the first three months of this year, venture capital investors poured nearly $2.9 billion into Lone Star State companies, Crunchbase data shows. Crunchbase attributes that healthy dollar amount to “enthusiasm around cybersecurity, defense tech, robotics, and de-extincting mammoths.”

During the first quarter of this year, roughly two-thirds of VC funding in Texas went to just five companies, says Crunchbase. Those companies are Austin-based Apptronik, Austin-based Colossal Biosciences, Dallas-based Island, Austin-based NinjaOne, and Austin-based Saronic.
