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

    New Houston-born app OpenToBites connects users over meals in 16 cities

    Friends and Food

    A Houston-born social is connecting foodies and social butterflies for shared meals. OpenToBites launched on Android on June 18 and iOS on June 22, and is available to use for free in Houston and beyond.

    Founded and operated by Houston developer Kelvin John, OpenToBites allows users to connect over meals in 16 cosmopolitan cities. That includes Austin and Houston in Texas, plus other American cities like Denver and New York, and even international destinations including Paris, Tokyo, and Sydney.

    The app is built on a simple concept, and a press release emphasizes that it's for anyone who wants "friendly company."

    “We built OpenToBites in response to several trends, including the rise of solo travel and the demand for social experiences that don’t feel like dating, networking, or large organized events,” said a spokesperson in the release. “We are not a dating app. We are offering shared food and conversation for people who want simple, in-person meal company in a public setting.”

    When signing up, users provide their first name, an optional profile photo, and a short bio. They mark themselves as a traveler, a local, or both, and have the option to select their age range or opt out.

    Once a profile is created, the user can search for existing meals or create a meal happening within the next 72 hours. To find an existing meal to join as a guest, they select the city, date, and apply filters for the number of seats, type of cuisine, and whether they want to share food with the table or order their own.

    Since someone has to get the party started, users can also take the initiative to start a meal as a host. They'll choose the date, time, and restaurant — anything is on the menu, as long as they can link to the restaurant on Google Maps or its own website.

    This divides users into "host" and "guest." Guests request to join a table, and a host can decide to accept the request or not. Guests aren't able to see the exact restaurant until their request is accepted, so hosts have a "helpful note" field to fill out with more information about the restaurant.

    A similar app called Timeleft launched in Austin in 2024, acting as a friendship matchmaker for small groups of strangers who answer personality questions, meet at a restaurant for dinner, and decide if they wanted to stay in touch.

    Though OpenToBites has a similar concept, it seems to work more like Couchsurfing, an app that connects travelers on their own terms. OpenToBites also emphasizes the immediate over the long-term — the meal itself is the social goal.

    OpenToBites is available for free on the App Store and Play Store; the app plans to grow each current city's user base before adding new locations.

    Houston mental health nonprofit expands platform statewide to connect more Texans with care

    access granted

    As mental health conversations evolve, the necessary pivot becomes how organizations across Texas navigate improved ways to help people access the care they need before their challenges become crises.

    That’s why Mental Health America of Greater Houston recently announced that it is expanding its Care Connect platform statewide.

    The expansion will address perhaps the most persistent barrier to behavioral healthcare—helping people find and navigate services that already exist.

    Care Connect’s extended reach comes at a time when more than 3.5 million adults in the state live with some kind of mental health condition and scores of those in need continue to struggle with accessing care despite the growing awareness of mental health needs.

    According to President and CEO Renae Vania Tomczak, Care Connect’s main goal was to remove as many obstacles as possible that Texans face when seeking mental health support.

    “Care Connect was about a two-year planning process,” Tomczak says. “It really began with asking what challenges people in the Greater Houston Area were facing regarding mental health. It’s not just accessing care, but the difficulty in navigating the mental healthcare system.”

    While provider shortages remain a challenge in some communities, Mental Health America of Greater Houston found that many individuals and families struggle simply to determine where to turn, how to identify the right provider and whether services are affordable.

    “We wanted to make it easier for people who have questions, who may never have had a mental health challenge before, or they’re a caregiver for somebody who has a mental health issue,” Tomczak says. “We wanted to be the place that people can come to get their questions answered and be connected to care.”

    Care Connect combines a vetted network of more than 1,000 providers and services across Texas with personalized navigation support.

    Searches generate care results based on insurance coverage, language preferences, ZIP code and clinical specialties.

    Additionally, one-on-one guidance and follow-up support are provided by bilingual resource specialists.

    The platform also seeks to address affordability, one of the most significant barriers to mental healthcare access. Through participating providers, eligible individuals can receive six to eight counseling sessions at no cost.

    “We have several providers who are willing to provide six to eight counseling sessions at no cost for people who do not have the means to pay for services themselves,” Tomczak says.

    When provider matches are unavailable, the organization can connect individuals with master’s-level mental health professionals working under the supervision of licensed clinicians.

    The statewide rollout builds on the platform’s early success in the Houston region, where it has helped thousands of individuals connect with mental health resources since launching last fall.

    According to Tomczak, the decision to expand was driven in part by growing demand from outside the organization’s traditional service area.

    “Last month we decided to take this program statewide,” she says. “It’s not just Houston that can use help in connecting to appropriate mental health services, but the whole state.”

    The Care Connect program’s promotion through healthcare providers, community organizations and public-sector partners across Texas is now one of Mental Health America of Greater Houston’s top priorities.

    Their goal is to create a stronger referral ecosystem that ultimately helps those who need access to mental health care more quickly.

    To facilitate that, the organization has also added free mental health screenings to its website so that users will better identify any symptoms related to anxiety, depression and other conditions.

    “Once they do that, then where do they go?” Tomczak says. “They’re not sure who to call and who can help them. At that point, we hope they’ll call us and talk to somebody live who can answer their questions and help them get started on the right path to improving their mental health.”

    With eyes on the future, Tomczak believes public understanding of mental health has improved in recent years, particularly following the COVID-19 pandemic, which brought new attention to the effects of stress, isolation and uncertainty.

    “The more we talk about it and have the opportunity to share that mental health conditions are traceable, the better,” she says.

    According to Tomczak, long-term, Care Connect aims to reduce roadblocks that exist between recognizing the need for help and receiving it.

    Ultimately, Care Connect hopes to create a robustly connected behavioral health system that gives Texans the ability to access mental health services swiftly and with confidence.

    “No one should have to navigate mental health challenges alone,” Tomczak adds. “Care Connect is here to help connect people with resources, services and answers to ensure they get the care they need to take the next step toward better mental health.”
