A Houston-based company that is electrifying chemical manufacturing has closed its largest round of funding to date.

Syzygy Plasmonics closed a $76 million series C financing round led by New York-based Carbon Direct Capital. The round included participation from Aramco Ventures, Chevron Technology Ventures, LOTTE CHEMICAL, and Toyota Ventures. The company's existing investors joining the round included EVOK Innovations, The Engine, Equinor Ventures, Goose Capital, Horizons Ventures, Pan American Energy, and Sumitomo Corporation of Americas. According to a news release, Carbon Direct Capital will join Syzygy's board and serve as the series C director.

"We were very attracted to the multiple use cases for the Syzygy reactor and the lifetime-value of each Syzygy customer," says Jonathan Goldberg, Carbon Direct Capital's CEO, in the release. "Emissions from hydrogen production total more than 900 million metric tons of carbon dioxide per year. Syzygy's photocatalysis technology is a key solution to decarbonize hydrogen production as well as other critical industries."

Syzygy Plasmonics has a technology that harnesses the power of light to energize chemical reactions — rather than the traditional process that is fueled by heat. The Syzygy approach reduces feedstock waste and produces fewer emissions when powered by renewable electricity. According to the release, some series C participants have also formed commercial agreements to deploy Syzygy's technology to meet their decarbonization goals.

The investment funding raised will help the company to "further development and delivery of all-electric reactor systems that eliminate fossil-based combustion from chemical manufacturing and reduce the carbon intensity of hydrogen, methanol, and fuel," per the release.

"Our mission is to decarbonize chemical and fuel production," says Syzygy Plasmonics CEO and Co-Founder Trevor Best in the release. "Syzygy's aim is to achieve 1 gigaton of carbon emissions reductions by 2040, and the series C financing is a key milestone in building towards that goal.

"Closing this fundraising round with such strong support from financial and strategic investors and with commercial agreements in hand is a signal to the market," he continues. "Forward-thinking companies have moved beyond setting decarbonization goals to executing on them. Syzygy is unique in that we are developing low-cost, low-carbon solutions to offer across multiple industries."

Syzygy was founded based off a breakthrough discover out of Rice University from co-founders and professors Naomi Halas and Peter Nordlander, who invented high-performance photocatalysts. The company's collaborators then engineered a novel reactor that uses easy-to-find low-cost materials like glass, aluminum, and LEDs instead of high-cost metal alloys. After several field trials of the scalable, universal chemical reactor platform, Syzygy expects commercial units scheduled to ship in 2023.

"Syzygy is hyper-focused on aligning energy, technology, and sustainability," says Suman Khatiwada, CTO and co-founder of Syzygy, in the release. "The projects we are delivering are targeting zero-emissions hydrogen from green ammonia, low-emissions hydrogen from combustion-free steam methane reforming, and sustainable fuels made from carbon dioxide and methane. This technology is the future of chemical manufacturing."

Syzygy has raised a $23 million series B round last year following its $5.8 series A in 2019.

Nine Houston companies landed on the 2026 Fortune Global 500 list, which ranks the world's largest corporations by revenue for the 2025 fiscal year.

Houston's showing on the list was led by energy companies, with Spring’s ExxonMobil claiming the top local spot. Here’s what Houston-area companies made the list, and where they ranked:

  • No. 15 ExxonMobil
  • No. 36 Chevron
  • No. 61 Phillip 66
  • No. 159 Sysco
  • No. 243 ConocoPhillips
  • No. 292 Enterprise Products Partners
  • No. 343 Plains GP Holdings
  • No. 460 SLB
  • No. 481 Hewlett Packard Enterprise

After 12 years as No.1, Arkansas-based Walmart was replaced this year by Seattle-based Amazon in the top spot for 2026. Amazon achieved this by bringing in $700 billion in revenue in 2025, representing a 12 percent increase from the previous year.

"Across global business, we see again and again that the leaders who are winning are those who embrace change,” Alyson Shontell, Fortune's editor in chief and chief content officer, said in a news release. "Amazon has topped the Fortune Global 500, knocking Walmart off its pedestal. The company has continually reinvented itself across new businesses and bold bets—including a $200 billion capital commitment, largely to building its capacity for AI and cloud computing, in this year alone."

The U.S. has 141 companies on the 2026 Fortune Global 500 list, which is the most of any country. Companies in America generated $15.5 trillion in aggregate revenues, a 6 percent increase from the previous year.

The number of women CEOs at Fortune Global 500 companies reached a record of 34 top leaders, who represented 6.8 percent of CEOs of companies on the list.

Technology was the standout growth industry on this year’s list, with 38 companies earning revenues that grew 20 percent to about $4 trillion in 2025, with profits climbing 36 percent to $835 billion. The financial sector accounted for the largest share of companies on the list again, with 123 companies in that sector. The energy sector claimed the No. 2 industry spot with 77 companies making the list.

In June, the Fortune 500 list was released, and Texas led the United States with 57 Fortune 500 companies headquartered in the state, generating $2.8 trillion in combined revenue.
