Houston investors are betting on a New York-based carbon capture startup's technology.

CarbonQuest announced it received series A funding from Houston-based Riverbend Energy Group. The terms of the deal were not disclosed. Founded in 2019, the company created its Distributed Carbon Capture technology that captures CO2 from buildings and onsite power generation systems, then liquifies and transports it to local businesses that need carbon for their production processes.

“We are one of the few carbon capture companies with commercial products on the market today, and this investment will enable us to continue bringing distributed carbon capture to a wider swath of the market,” Shane Johnson, president and CEO of CarbonQuest, says in a news release. “We are also excited to attract new talent and expand our North American operations.”

The company's compact, modular carbon capture solution has already been deployed in several New York City buildings and reports that it is focused on natural gas emissions from distributed onsite power generation in 2024. The fresh funding will help CarbonQuest lower its cost for customers and address new market segments, including biogenic sources of CO2, utility infrastructure, and more, per the release.

Additionally, the company plans to advance development of its Carbon Management Software, a platform that provides real-time data and analytics for users. Riverbend's Joe Passanante and Eric Danziger will join CarbonQuest’s board of directors as a part of the deal.

“We are thrilled to partner with CarbonQuest, a company at the forefront of distributed carbon capture technology,” Passanante, managing director at Riverbend, says in the release. “This investment reflects our commitment to advancing solutions that play a critical role in decarbonization.

"CarbonQuest’s innovative approach not only addresses that need, but also offers scalable, economically viable solutions that can be deployed across a wide range of markets," he continues. "We are excited to collaborate with CarbonQuest’s experienced and talented team and believe this partnership will be a game changer in multiple markets, helping to unlock the full potential of distributed carbon capture and significantly contribute to global climate goals.”

Chevron, TotalEnergies back energy storage startup's $15.8M series A

money moves

A California startup that's revolutionizing polymer cathode battery technology has announced its series A round of funding with support from Houston-based energy transition leaders.

LiNova Energy Inc. closed a $15.8 million series A round led by Catalus Capital. Saft, a subsidiary of TotalEnergies, which has its US HQ in Houston, and Houston-based Chevron Technology Ventures, also participated in the round with a coalition of other investors.

LiNova will use the funds with its polymer cathode battery to advance the energy storage landscape, according to the company. The company uses a high-energy polymer battery technology that is designed to allow material replacement of the traditional cathode that is made up of cobalt, nickel, and other materials.

The joint development agreement with Saft will have them collaborate to develop the battery technology for commercialization in Saft's key markets.

“We are proud to collaborate with LiNova in scaling up its technology, leveraging the extensive experience of Saft's research teams, our newest prototype lines, and our industrial expertise in battery cell production," Cedric Duclos, CEO of Saft, says in a news release.

CTV recently announced its $500 million Future Energy Fund III, which aims to lead on emerging mobility, energy decentralization, industrial decarbonization, and the growing circular economy. Chevron has promised to spend $10 billion on lower carbon energy investments and projects by 2028.

Chesapeake Energy backs Houston geothermal tech co. in $17M series A

fresh funding

A Houston geothermal startup has announced the close of its series A round of funding.

Houston-based Sage Geosystems announced the first close of $17 million round led by Chesapeake Energy Corp. The proceeds aim to fund its first commercial geopressured geothermal system facility, which will be built in Texas in Q4 of 2024. According to the company, the facility will be the first of its kind.

The venture is joined by technology investor Arch Meredith, Helium-3 Ventures and will include support from existing investors Virya, LLC, Nabors Industries Ltd., and Ignis Energy Inc.

“The first close of our Series A funding and our commercial facility are significant milestones in our mission to make geopressured geothermal system technologies a reality,” Cindy Taff, CEO of Sage Geosystems, says in a news release. “The success of our GGS technologies is not only critical to Sage Geosystems becoming post-revenue, but it is an essential step in accelerating the development of this proprietary geothermal baseload approach. This progress would not be possible without the ongoing support from our existing investors, and we look forward to continuing this work with our new investors.”

The 3-megawatt commercial facility will be called EarthStore and will use Sage’s technology that harvests energy from pressurized water from underground. The facility will be able to store energy — for short and long periods of time — and can be paired with intermittent renewable energy sources like wind and solar. It will also be able to provide baseload, dispatchable power, and inertia to the electric grid.

In 2023, Sage Geosystems debuted the EarthStore system in a full-scale commercial pilot project in Texas. The pilot produced 200 kilowatt for more than 18 hours, 1 megawatt for 30 minutes, and generated electricity with Pelton turbines. The system had a water loss of less than 2 percent and a round-trip efficiency (RTE) of 70-75.

Houston-based geothermal energy startup releases promising results of Texas pilot

hot off the press

As it seeks an additional $30 million in series A funding, Houston startup Sage Geosystems has released promising results from a test of its technology for underground storage of geothermal energy.

Sage says the pilot project, conducted at a Shell-drilled oil well in the Rio Grande Valley’s Starr County, showed the company’s long-term energy storage can compete on a cost basis with lithium-ion battery storage, hydropower storage, and natural gas-powered peaker plants. Peaker plants supply power during periods of peak energy demand.

Furthermore, Sage’s geothermal technology will provide more power capacity at half the cost of other advanced geothermal systems, the company says.

Sage’s storage system retrofits oil and gas wells with the company’s geothermal technology. But the company says its technology “can be deployed virtually anywhere.”

The system relies on mechanical storage instead of battery storage. In mechanical storage, heat, water, or air works in tandem with compressors, turbines, and other machinery. By contrast, battery storage depends on chemistry to get the job done.

“We have cracked the code to provide the perfect complement to renewable energy. … The opportunities for our energy storage to provide power are significant — from remote mining operations to data centers to solving energy poverty in remote locations,” former Shell executive Cindy Taff, CEO of Sage, says in a September 12 news release.

Sage says its storage capacity can be connected to existing power grids, or it can develop microgrids that harness stored energy.

An August 2023 article in The New York Times explained that Sage “is pursuing fracked wells that act as batteries. When there’s surplus electricity on the grid, water gets pumped into the well. In times of need, pressure and heat in the fractures pushes water back up, delivering energy.”

The pilot project, a joint venture between Sage and the Bureau of Economic Ecology at the University of Texas at Austin, was performed as part of a feasibility study financed by the Air Force. Now that the test results are in, Sage plans to build a prototype geothermal project at the Air Force’s Ellington Field Joint Reserve Base in Houston.

Sage says another feasibility study is underway in the Middle East in partnership with an unnamed oil and gas company.

Founded in 2020, Sage plans to raise another $30 million to accompany its previous series A funding.

The Virya climate fund and Houston-based drilling contractor Nabors Industries helped finance the pilot project in Starr County.

Last year, Sage announced it received an undisclosed amount of equity from Houston-based Ignis H2 Energy, a geothermal exploration and development company, and Dutch energy company Geolog International. Also last year, Sage said Nabors and Virya had teamed up for a $12 million investment in the startup.

Houston energy tech company Molecule makes gas operations acquisition

software acquisition

Houston-based energy trading risk management (ETRM) software company Molecule has announced the acquisition of Dallas-based Trilogy Energy Solutions.

Molecule CEO Patrick Smith called the deal a "defining moment" for the company, as it allows Molecule's platform to expand to include physical gas operations.

“For years, this industry has drawn the ETRM box too small, creating inefficient silos by treating trading and physical operations as separate budgets and separate problems, when the real cost lives in the handoffs between them," Smith said in a news release. "Trilogy’s domain expertise in physical gas operations closes that gap. Together, we can give producers, midstream operators, and trading desks something the market has been asking for: a single, integrated view from wellhead to trading desk, without the manual reconciliation, spreadsheet workarounds, and legacy handoffs that slow the industry down.”

Trilogy, founded in 2014, is a provider of cloud-based software for the day-to-day logistics of physical natural gas operations. The platform allows users—including producers, marketers, midstream companies, pipeline operators and others—to manage activities such as pipeline nominations, gas gathering operations and more. Thus far, Molecule's platform has focused on energy trading and managing financial and commercial activities.

Through the acquisition, the combined company will now offer a full-stack enabled ETRM and energy operating system. Users of both platforms can expect continuity of service, according to the companies.

“Molecule has always been about meeting trading teams where they actually work, focused on being fast, accurate, and deeply integrated into their day-to-day workflow,” Sameer Soleja, founder and president of Molecule, added in the release. “Bringing Trilogy into the Molecule family extends that mission from the trading desk into the physical operations of the gas business. The two platforms complement each other exceedingly well, and the combined product will be able to offer all-in-one capabilities that lead the ETRM market, both in its tech-forward nature, and in its depth.”

Molecule expects the combined platform to help users reduce manual month-end close work, cut costs, and improve data accuracy and decision-making.

Trilogy's Chief Product Officer Jeremy Frye will join the Molecule team, along with others from Trilogy.

“Trilogy has spent decades building the trust of companies across the physical natural gas industry by delivering software that stands up to the demands of physical gas operations... It’s a rare combination that brings the best of both worlds, and I’m energized about what our teams will build together,” Frye added in the release.

California-based Sundance Growth, an existing investor in Molecule, supported the acquisition. The software growth equity firm raised a $125 million debut fund in 2025 and focuses on B2B SaaS companies.

Sundance led Molecule's Series B round, which closed last summer for an undisclosed amount. At the time, Soleja said the funding would allow Molecule to "double down on product innovation, grow our team, and reach even more markets."

Houston geothermal startup adds former bp, Calpine execs to C-suite

new leaders

XGS Energy, a Houston-based developer of geothermal power systems, has added several energy industry veterans to its C-suite this summer.

The company named Al Vickers as its new chief operating officer earlier this month. Vickers will replace Ghazal Izadi in the role, as she moves into the chief growth officer position.

Vickers previously served as CEO of bp's U.S. Low Carbon Energy business and most recently was COO of Houston-based Grid United, which develops next-generation transmission infrastructure.

“I have spent my career developing, building, and operating large, complex energy infrastructure, and I am excited to work with XGS’s proven technology, which is ready to deliver clean, round-the-clock power at the scale the grid and customers need,” Vickers said in a news release. “XGS sits at the intersection of innovation, affordability, demand growth, responsible infrastructure development, and long-term energy resilience. I’m excited to roll up my sleeves and apply best practices from both oil and gas and infrastructure development to deliver gigawatt-scale geothermal projects.”

Kurt Fricker, who most recently held leadership roles at Hess Corporation, was also announced as XGS's new chief procurement officer.

The hires come shortly after XGS announced Richard Chong as its new chief financial officer in May.

Chong joins XGS from Houston-based power producer Calpine, where he most recently was vice president of finance. His work there included leading $2.25 billion in financing for Geysers, the world’s largest geothermal power complex.

Chong says XGS’ proven technology and the rising demand for clean power will help the company execute on its multi-gigawatt pipeline.

“I look forward to applying the experience I’ve built over two decades in energy finance to help XGS deliver clean, reliable power to customers and unlock the massive development opportunity ahead for next-generation geothermal,” Chong said in the release.

XGS’ first project is a 150-megawatt geothermal facility in New Mexico. It will supply around-the-clock electricity to the grid operated by Public Service Co. of New Mexico in support of Meta data centers.

XGS recently tapped Houston-based energy technology company Baker Hughes to provide engineering services for the New Mexico project.

XGS’ geothermal system uses thermally conductive materials to deliver affordable energy anywhere hot rock exists — without the need for water resources or specific geological conditions. This results in lower-risk projects, more site options, easier permitting and faster deployment.

Since 2023, XGS has raised nearly $57 million in venture capital.

XGS launched in 2008 in Palo Alto, California, as Geothermic Solution. In conjunction with its Series A round in 2023, the company rebranded to its current name. The company recently moved its headquarters to Houston, according to the Houston Business Journal.
