Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.

Houston company closes $76M series C round to fuel its mission of reducing carbon emissions

money moves

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.

3 fast-growing Houston scaleups named Innovation Awards finalists

meet the finalists

From IPOs to groundbreakings, some of Houston's most innovative companies reached major milestones this year.

As part of the 2026 Houston Innovation Awards, our Scaleup of the Year category honors innovative later-stage startups that have recently reached a significant milestone in company growth. Three scaleups have been named finalists for the 2026 award.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.

Texas ranks among top 10 best states for jobs in new report

jobs report

Business boosters often describe Texas as an economic engine. A new ranking from personal finance website WalletHub underscores that assessment.

WalletHub put Texas at No. 8 on its new list of the best states for jobs. Nebraska grabbed the No. 1 spot, and West Virginia landed at No. 50.

To compile the list, WalletHub evaluated 34 metrics from two categories: job market and economic environment. It then crunched the numbers to create a score for each state. A score of 100 represents the most favorable conditions for job seekers.

Texas ranked 25th in the job market category and second in the economic environment category. Texas’ eighth-place showing was based on a score of 59.23.

“The best states for jobs make it easier for residents to find and retain jobs, and employers in these states also offer very competitive compensation and benefits,” WalletHub analyst Chip Lupo said. “In addition, the top states are great places for people looking to raise a family, ranking among the best states for working parents.”

Data released in late October shows Texas led all states for job growth during the 12-month period that ended in September. In that time, Texas added 154,300 jobs at an annual rate of 1.1 percent.

“Texas is America’s jobs leader,” Gov. Greg Abbott said in a press release. “Businesses big and small invest with confidence in Texas and in our growing and skilled workforce. That means bigger paychecks for more Texans and more opportunities for Texas families to prosper for years to come.”

Abbott noted Texas reigns as the top state for attracting job-producing businesses and creating jobs at small businesses.

The Houston metro area actually saw a decline in new jobs in September, losing 7,300 jobs compared with the previous month. On a year-over-year basis, the region added 13,500 jobs, with professional and business services, construction, and private education and health services leading the growth.
