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," she continues.

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 sustainability startup founder on why geothermal is a 'cornerstone' tech for energy transition

Q&A

Geothermal energy is an integral part of decarbonizing the energy industry, and Sage Geosystems CEO Cindy Taff believes her company's tech has what it takes to lead the way.

Founded in Houston in 2020, Sage Geosystems is focused on two business lines — energy storage and geothermal. In addition to developing these technologies, Taff says Sage has "cracked the code" on both reducing costs and maximizing electricity output. Sage has customers ranging from Nabors, the world’s largest land-based drilling company, and Virya LLC, an investor in climate ventures with high impact of eliminating global greenhouse gas emissions or sequestering CO2

In a Q&A that originally ran on EnergyCapital, she explains why she's so optimistic about geothermal and her company's technology.

EnergyCapital: Why do you believe geothermal has a major role to play in the energy transition?

Cindy Taff: Geothermal energy is not just a contender in the energy transition; it is a cornerstone. The question isn’t if we can drive down the costs to be competitive with wind, solar, and natural gas—it’s when. As renewable credits for solar and wind begin to expire, these industries will face the reality of their “real costs.”

As a 24/7 renewable energy source, it provides a constant and reliable power supply, unlike the intermittent nature of solar and wind. Moreover, the rising costs of lithium-ion batteries, driven by the increasing scarcity of lithium and cobalt, further underscore geothermal’s economic viability.

My extensive experience in both geothermal and the O&G sector is a testament to the synergistic relationship between these industries. The skills honed in O&G are not only transferable—they are essential to advancing geothermal technologies. In summary, the O&G industry can make a huge impact to geothermal by systematically driving down costs while scaling up, which is exactly what we did for unconventional shales.

EC: When it comes to finding partners or investors, what are you looking for? What should potential partners/investors know about Sage?

CT: Our technology is ready to scale today, not five to 10 years into the future. We will deliver our first energy storage power plant in 2024 and our first enhanced geothermal power plant in 2025. We are looking for synergies with investors, such as companies with power market or O&G expertise.

In addition, we seek to partner with others who have local content and relationships in places around the world to enable us to quickly and broadly scale our technologies. Sage's technologies are extremely flexible, in that we can deliver energy storage or enhanced geothermal to the utility grid or behind-the-meter to targeted commercial customers, including a dedicated microgrid (i.e., for the U.S. Air Force). Our technologies can provide electricity to remote locations such as mining operations or to large population centers such as Houston, and everything in between.

EC: What's the biggest challenge Sage is facing as an energy transition startup and how do you plan to tackle it?

CT: A common misunderstanding about Sage is that we only do energy storage or that we only do geothermal. However, we do both and the technologies build on one another. Essentially, our energy storage technologies will allow us to "walk" before we "run" with geothermal. On a related point, at this point in the energy transition, time to commercialization and affordability of new clean technology are the leading factors in terms of climate impact. As the first geothermal company to deliver a cost-effective commercial enhanced geothermal system, we are poised to truly make a meaningful difference.

EC: As a woman in a male-dominated industry tackling a global problem, what's been your biggest lesson learned? What's your advice to fellow energy tech female founders?

CT: In my journey as a woman in the energy tech industry, I’ve been fortunate to focus on the work and the global challenges we’re addressing, rather than on any gender-based obstacles. My biggest lesson learned is that innovation and leadership know no gender. Success is driven by perseverance, vision, and collaboration.

Top Houston-based sustainability startups share their 4 biggest challenges

houston innovation awards

Six Houston-area sustainability startups have been named finalists in the 2023 Houston Innovation Awards, but they didn't achieve this recognition — as well as see success for their businesses — without any obstacles.

The finalists were asked what their biggest challenges have been. From funding to market adoption, the sustainability companies have had to overcome major obstacles to continue to develop their businesses.

The awards program — hosted by InnovationMap, and Houston Exponential — will name its winners on November 8 at the Houston Innovation Awards. The program was established to honor the best and brightest companies and individuals from the city's innovation community. Eighteen energy startups were named as finalists across all categories, but the following responses come from the finalists in the sustainability category specifically.

    Click here to secure your tickets to see who wins.

    1. Securing a commercial pilot

    "As an early-stage clean energy developer, we struggled to convince key suppliers to work on our commercial pilot project. Suppliers were skeptical of our unproven technology and, given limited inventory from COVID, preferred to prioritize larger clients. We overcame this challenge by bringing on our top suppliers as strategic investors. With a long-term equity stake in Fervo, leading oilfield services companies were willing to provide Fervo with needed drilling rigs, frack crews, pumps, and other equipment." — Tim Latimer, founder and CEO of Fervo Energy

    2. Finding funding

    "Securing funding in Houston as a solo cleantech startup founder and an immigrant with no network. Overcome that by adopting a milestone-based fundraising approach and establishing credibility through accelerator/incubator programs." — Anas Al Kassas, CEO and founder of INOVUES

    "The biggest challenge has been finding funding. Most investors are looking towards software development companies as the capital costs are low in case of a risk. Geothermal costs are high, but it is physical technology that needs to be implemented to safety transition the energy grid to reliable, green power." — Cindy Taff, CEO of Sage Geosystems

    3. Market adoption

    "Market adoption by convincing partners and government about WHP as a solution, which is resource-intensive. Making strides by finding the correct contacts to educate." — Janice Tran, CEO and co-founder of Kanin Energy

    "We are creating a brand new financial instrument at the intersection of carbon markets and power markets, both of which are complicated and esoteric. Our biggest challenge has been the cold-start problem associated with launching a new product that has effectively no adoption. We tackled this problem by leading the Energy Storage Solutions Consortium (a group of corporates and battery developers looking for sustainability solutions in the power space), which has opened up access to customers on both sides of our marketplace. We have also leveraged our deep networks within corporate power procurement and energy storage development to talk to key decision-makers at innovative companies with aggressive climate goals to become early adopters of our products and services." — Emma Konet, CTO and co-founder of Tierra Climate

    4. Long scale timelines

    "Scaling and commercializing industrial technologies takes time. We realized this early on and designed the eXERO technology to be scalable from the onset. We developed the technology at the nexus of traditional electrolysis and conventional gas processing, taking the best of both worlds while avoiding their main pitfalls." — Claus Nussgruber, CEO of Utility Global

    Online platforms have long simplified the process of buying, selling, and trading event tickets. But what happens when your tickets don’t sell or when you’re stuck with costly season tickets you can’t use? You might end up giving them away or leaving them unused, leading to a financial loss either way.

    This is the challenge that Houstonian Jerin Varkey is willing to address with Offer Approved, a new platform that empowers sellers and buyers, guaranteeing that no seat goes unused.

    The idea took root around two years ago when Varkey, a passionate sports fan and season ticket holder, faced a new challenge. After becoming a parent, he found himself unable to attend every game. Frustrated with traditional resale platforms, he quickly realized that high fees and limited time made it difficult to sell all his tickets, causing him to lose money each time. Continue reading.

    Meeting America’s growing energy demands: Houston expert on how to build a workforce to fuel the future

    guest column

    U.S. energy consumption is projected to rise nearly 20 percent over the next decade — driven by advancements like AI, increasing electrification, and the growing demand for electric vehicles. While attention often centers on the technologies that generate power, the driver behind this transformation is the skilled workforce, which comprises men and women dedicated to enabling the nation's growth. Ensuring a steady supply of qualified workers is imperative for meeting the energy demands of the coming decade.

    Developing this talent pipeline starts with a commitment to education. As the energy landscape evolves rapidly, educators play a crucial role in equipping the next generation with the skills to embrace new technologies and adapt to changing industry demands. This commitment to education is central to the Energy Education Foundation's (EEF) mission. It's also a cornerstone of EEF partner and board member, Coterra Energy's, efforts to be recognized as a leader in energy education.

    At a recent Energy Education Exchange, hosted by Coterra and EEF, in collaboration with industry partners such as the American Petroleum Institute (API) and the Consumer Energy Alliance, over 50 educators and industry leaders gathered in Houston to address this need.

    During the three-day event, educators, administrators, and industry professionals were immersed in the many facets of the oil and gas industry, learning best practices for incorporating energy education into their programs.

    Educators experienced an in-depth tour of the San Jacinto College Center for Petrochemical, Energy, and Technology. As the largest petrochemical training facility in the Gulf Coast region, the center offered a unique look at industry-standard equipment, including a multifunctional glass pilot plant lab, a glycol distillation unit, and 35 specialized training labs. Participants engaged in demonstrations led by faculty and students, exploring circuits, on-campus refineries, and advanced machinery — essential experiences that bring classroom lessons to life.

    The event also highlighted efforts at the high school level, exemplified by a presentation and tour at Energy Institute High School in Houston's historic Third Ward. The Institute showcased how project-based learning, robotics, and hands-on fabrication labs are shaping students' skills for the energy sector. The high school's mission aligns perfectly with EEF’s goals: sparking interest in energy among younger students, developing their skills, and paving a pathway toward lifelong careers in the industry.

    API's "Lights On" reception concluded the first day, promoting networking among educators and industry professionals. By facilitating these connections, we are ensuring that educators learn about energy careers and establish ongoing relationships that can translate into opportunities for their students.

    Keynotes throughout the exchange included Peter Beard, Senior Vice President of the Greater Houston Partnership, and Chris Menefee, President of Unit Drilling Company, who further emphasized the critical need for workforce development. Beard noted, "As our economy grows, we must ensure we have the electrons and the workforce to support that growth." He stressed that aligning skills with job requirements is more than just matching credentials; it's about upskilling and offering real career mobility.

    Menefee echoed this sentiment, acknowledging the pressures on educators to prepare students for an ever-changing job market. He underscored his company's commitment to "quality over quantity" in hiring, prioritizing well-trained individuals, and emphasizing the value of strong foundational skills, which begin in the classroom, especially career and technology classrooms.

    The Energy Day Festival in Houston provided an additional opportunity for educators and administrators to engage directly with the industry. Thousands attended, visiting booths set up by companies, trade groups, and educational institutions. EEF's own Mobile Energy Learning Units offered interactive exhibits designed to teach students of all ages about energy and career opportunities. The Units appearance at Energy Day was made possible by the American Petroleum Institute.

    Looking forward, the U.S. must expand opportunities for the next generation of energy workers and provide educators with the necessary resources. The Energy Education Exchange is a significant step forward, but one initiative alone cannot shape an entire workforce. All stakeholders involved must invest in tools, training, and programs that empower educators and provide opportunities for students. As Domestic Policy Advisor Neera Tanden recently stated, "Apprenticeships are essential for advancing the economy and building critical skills."

    It's time for a broader approach to ensure that the U.S. meets energy demands and leads the world in innovation and education. At the Energy Education Foundation, we are proud to be at the forefront of this mission, working alongside Coterra and other partners. By empowering educators, we empower the next generation—one that will fuel our nation's future. Together, we can build a workforce ready for the challenges ahead.

    ———

    Kristen Barley is the executive director of the Energy Education Foundation, an organization dedicated to inspiring the next generation of energy leaders by providing comprehensive, engaging education that spans the entire energy spectrum.
