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.

Houston startup’s brain implant for depression advances to clinical trial

moving forward

Houston-based Motif Neurotech has received FDA approval to move forward with its first clinical trial for its innovative way to fight treatment-resistant depression and other mental health disorders.

The company has developed a brain-computer interface technology based on research from Rice University. The blueberry-sized, wirelessly powered implantable device known as the Digitally-programmable Over-brain Therapeutic (DOT) stimulator delivers electrical stimulation to brain circuits linked to depression. The DOT stimulator sits in the skull above the dura without touching the brain and is considered an alternative to transcranial magnetic stimulation, which requires multiple treatment sessions and can cause headaches.

“The goal for this technology is that it would be the mental health equivalent of a continuous glucose monitor for diabetes,” Jacob Robinson, a Rice University professor of electrical computer engineering and bioengineering and CEO of Motif Neurotech, said in a news release. “What has been really special for me personally on this journey is to be able to work all the way from a concept through the process of research and development funded by the federal government at Rice, and take that into a product that is going to affect people’s lives for the better.”

Eligible adults whose depression has not improved after trying multiple therapies can take part in the study. The clinical trial will be conducted in collaboration with Baylor College of Medicine, Brain Health Consultants (Houston), UT Health Houston, Massachusetts General Brigham, Emory Healthcare, University of Iowa, University of Utah Health and New York University, according to Rice.

Motif also announced that it was one of the first teams selected for ARPA-H’s EVIDENT initiative, which recently awarded up to $139.4 million to spur new, effective therapies for behavioral health. Through the initiative, Motif will collect additional data alongside its clinical trial.

“The idea with this funding is to support a number of teams who have rapid-acting interventions for a mental health condition and to collect additional data to help determine with greater precision whether a treatment is working, how it is working and which patients are benefitting most from which course of treatment,” Robinson added in the release.

Motif Neurotech was spun out of Robinson’s and Professor Kaiyuan Yang’s labs at Rice, along with collaborators and co-founders Dr. Sameer Sheth at Baylor College of Medicine and Dr. Sunil Sheth at the University of Texas Health Science Center at Houston. It was founded through the Rice Biotech Launch Pad. The company closed its Series A round with an oversubscribed $18.75 million last year.
