Houston clean energy company closes $5.8M Series A and prepares to revolutionize the industry

Game changer

A Houston technology company is doing something that, for many decades, wasn't thought to be possible. Syzygy Plasmonics is creating a hydrogen fuel cell technology that produces a cheaper source of energy that releases fewer carbon emissions.

The hydrogen-fueled technology originated out of research done over two decades by two Rice University professors, Naomi Halas and Peter Nordlander.

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

Syzygy's technology is structured more like a battery than that of a combustion engine. Inside the technology, there are cells, lights, and mirrors making as bright as possible, which then spurs a reaction that creates energy. It has the potential to be cheaper — it's made with cheaper materials — and, of course, cleaner than traditional fueling technology with fewer carbon emissions released.

This new photocatalytic chemical reactor has the potential to shake up the industrial gas, chemical, and energy industries — something that hasn't gone unnoticed by investors. Syzygy just closed a $5.8 million Series A round led by MIT's The Engine and Houston-based The GOOSE Society of Texas. Evok Innovations, a previous investor in the company, and angel investors from the Creative Destruction Lab also contributed to the round.

The funds will allow for Syzygy to continue to develop its technology and grow its team. Best tells InnovationMap that he expects to launch a full-size pilot by the end of 2020 and is already in talks with potential clients who are interested in the technology for industrial purposes.

"We're starting to solidify relationships and get customers ready," Best says.

Earlier this year, the company also received funding from the Department of Energy and from the National Science Foundation SBIR Program. The DOE tasked Syzygy with creating a reactor that transforms ammonia into hydrogen for fueling purposes. For the SBIR Program, the company is creating a reactor that processes carbon dioxide.

NASA names new chief astronaut based in Houston

new hire

NASA has a new chief astronaut. Scott Tingle, stationed at the space agency’s Johnson Space Center in Houston, assumed the post Nov. 10.

Tingle succeeds NASA astronaut Joe Acaba, who had been chief astronaut since February 2023. Acaba now works on the staff of the Johnson Space Center’s director.

As chief astronaut, Tingle runs NASA’s Astronaut Office. His job includes developing astronauts’ flight crew operations and assigning crews for space missions, such as Artemis missions to the moon.

Tingle, a former captain in the Navy, was named a NASA astronaut candidate in 2009. He has logged over 4,500 flight hours in more than 50 aircraft.

Tingle was a flight engineer aboard the International Space Station, where he spent 168 days in orbit during two expeditions that launched in December 2017. Since returning to Earth, he has held various roles in the Astronaut Office, including mission support, technical leadership and crew readiness.

Before joining NASA, Tingle worked in El Segundo, California, on the technical staff of The Aerospace Corp., a nonprofit that supports U.S. space programs.

Tingle recalls expressing his desire to be an astronaut when he was 10 years old. It took him four tries to be accepted by NASA as an astronaut candidate.

“The first time I figured it was kind of too early. The second application, they sent out some feelers, and that was about it. Put in my third application, and got a couple of calls, but it didn’t quite happen,” Tingle said in an article published on the website of Purdue University, his alma mater.

ExxonMobil officially pauses plans for $7B Baytown hydrogen plant

Change of Plans

As anticipated, Spring-based oil and gas giant ExxonMobil has officially paused plans to build a low-hydrogen plant in Baytown, Chairman and CEO Darren Woods told Reuters in late November.

“The suspension of the project, which had already experienced delays, reflects a wider slowdown in efforts by traditional oil and gas firms to transition to cleaner energy sources as many of the initiatives struggle to turn a profit,” Reuters reported.

Woods signaled during ExxonMobil’s second-quarter earnings call that the company was weighing whether it would move forward with the proposed $7 billion plant.

The Biden-era Inflation Reduction Act created a new 10-year incentive, the 45V tax credit, for production of clean hydrogen. But under President Trump’s "One Big Beautiful Bill Act," the window for starting construction of low-carbon hydrogen projects that qualify for the tax credit has narrowed. The Inflation Reduction Act mandated that construction start by 2033. But the Big Beautiful Bill switched the construction start time to early 2028.

“While our project can meet this timeline, we’re concerned about the development of a broader market, which is critical to transition from government incentives,” ExxonMobil Chairman and CEO Darren Woods said during the company’s second-quarter earnings call.

Woods had said ExxonMobil was figuring out whether a combination of the 45Q tax credit for carbon capture projects and the revised 45V tax credit would enable a broader market for low-carbon hydrogen.

“If we can’t see an eventual path to a market-driven business, we won’t move forward with the [Baytown] project,” Woods said.

“We knew that helping to establish a brand-new product and a brand-new market initially driven by government policy would not be easy or advance in a straight line,” he added.

ExxonMobil announced in 2022 that it would build the low-carbon hydrogen plant at its refining and petrochemical complex in Baytown. The company has said the plant is slated to go online in 2027 and 2028.

ExxonMobil had said the Baytown plant would produce up to 1 billion cubic feet of hydrogen per day made from natural gas, and capture and store more than 98 percent of the associated carbon dioxide. The plant would have been capable of storing as much as 10 million metric tons of CO2 per year.
