When Cindy Taff was a vice president at the giant oil and gas company Shell in Houston, her middle schooler Brianna would sometimes look over her shoulder as she worked from home.

“Why are you still working in oil and gas?” her daughter asked more than once. “Is there a future in it? Why aren’t you moving into something clean?”

The words weighed on Taff.

“As a parent you want to give direction, and was I giving her the right direction?” she recalled.

At Shell, Taff was in charge of drilling wells and bringing them into production. She worked on oil and natural gas that's called unconventional in the industry, because the oil or natural gas is difficult to get out of the ground — it doesn't naturally gush out like in movies. It's a term often used for oily shale rock. Taff was somewhat unconventional for the industry, too. Her coworkers used to tease her for driving an efficient hybrid.

“You’re not helping oil and gas prices by driving a Prius," they'd say.

Taff wanted Shell to pursue the energy that comes from the Earth's natural heat — geothermal. Her team looked into it, but Shell never greenlit any of those projects, saying it would take too much time to recoup the investment.

When Brianna went to college, she was passionate about energy too, but she wanted to work on renewables. After her sophomore year, in the summer of 2020, she got an internship at a geothermal company — one that in fact had just been launched by Taff's former colleagues at Shell — Sage Geosystems in Houston.

Now it was Taff looking over her daughter's shoulder and asking question as she worked from home during the pandemic.

And Sage executives were talking to Brianna, too. “We could use your mom here," they said. "Can you get her to come work for us?” Brianna recalled recently.

That's how Cindy Taff left her 36-year career at Shell to become chief operating officer at Sage.

“I didn't understand why Shell wasn't pursuing it,” she said about applying the company's drilling expertise to heat energy. "Then I got this great opportunity to pivot from oil and gas and work with these guys that I have the utmost respect for. And also, I wanted to make my daughter proud, quite frankly.”

Brianna Byrd, now 24, is the operations engineer and spokesperson at the company. She's glad her mother, now CEO, left oil and gas.

“Of course I’m biased, she’s my mom, but I don’t think Sage would be where it is without her,” she said.

The United States is a world leader in electricity made from geothermal energy, but this kind of electricity still accounts for less than half a percent of the nation’s total large-scale generation, according to the U.S. Energy Information Administration. In 2023, most geothermal electricity came from California, Nevada, Utah, Hawaii, Oregon, Idaho and New Mexico, where there are reservoirs of steam, or very hot water, close to the surface.

The Energy Department estimates this next generation of geothermal projects, like what Sage is doing, could provide some 90 gigawatts by 2050 — enough to power 65 million homes or more. That hinges on private investment, and on companies like Sage introducing this form of energy to regions where, until now, it’s been thought to be impossible.

How it works

Sage has two main technologies: The first makes electricity out of heat. The company drills wells and fractures hot, dry rock. Then electric pumps push water into those fractures, heating it up, and the hot water gets jettisoned to the surface where it spins a turbine.

But a funny thing happened during testing in Starr County, Texas. In late 2021, the team realized much of their technology could also be used to store energy.

If that works, it could be a big deal. Currently, to store energy at large scale, the United States is adding batteries, mostly lithium-ion type, to solar and wind projects, so they can charge up and send electricity back to the electric grid when the sun is not shining or the wind is not blowing. These batteries typically supply four hours maximum power.

Sage envisions some of its technology placed at solar and wind farms, too. When electricity demand is low, they'll use extra energy from a solar or wind farm to run electric pumps, pumping water into the underground fractures, leaving it there until demand for electricity increases — storing the energy beneath the Earth's surface for hours, days or even weeks.

It's a novel way to use the technology, said Silviu Livescu, lead author on a report looking at the future of geothermal in Texas. Livescu knows Taff and has followed the company's progress.

“It’s the right moment for companies like Sage with a purpose, with a mission and with the technology to show that geothermal indeed is the energy source we need to address climate change,” said Livescu, who co-founded a different geothermal startup in Austin, Texas.

These days, Taff is often out in front, talking with politicians and policymakers about the potential of geothermal. She attended the United Nations COP28 climate talks last year to share her vision for this kind of energy.

Sage has raised $30 million so far and is growing.

It's building a small (3-megawatt), geothermal energy storage system at San Miguel Electric Cooperative, Inc., south of San Antonio this year. It's working with U.S. military facilities in Texas that see geothermal as a way to power their bases securely. Sage recently announced partnerships for heating communities in Bucharest, Romania; clean electricity from geothermal for Meta's data centers, and energy storage and geothermal projects in California.

The company is final-testing a proprietary turbine to more efficiently convert heat to electricity.

Because of her oil and gas background, Taff said she knows geothermal will only be adopted widely if the cost comes down. The mantra at Sage is: It's going to be clean and it's going to be cheap. She's excited to be working in a field she feels is on the cusp of playing a big role in cleaning and stabilizing the electrical grid.

“I’ve never looked back,” she said. “I love what I’m doing and I think it’s going to be transformative.”

big tech

A Houston company has signed a new agreement with Meta Platforms Inc. — Facebook's parent company — to power the tech giant's data center growth.

Houston-based Sage Geosystems agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta. The companies made the announcement this week at the United States Department Energy’s Catalyzing Next Generation Geothermal Development Workshop.

The deal is significant because it's the first next-generation geothermal project located to the east of the Rocky Mountains, the companies report in a news release.

“This announcement is the perfect example of how the public and private sector can work together to make the clean energy transition a reality,” Cindy Taff, CEO of Sage Geosystems, says in the release. “We are thrilled to be at the forefront of the next generation of geothermal technology and applaud the DOE for supporting the commercialization of innovation solutions.

"As energy demand continues to grow, the need for reliable, resilient and sustainable power is paramount and our partnership with Meta underscores the critical need for innovative and sustainable energy solutions like ours,” she continues.

The project's first phase will aim to be operating in 2027. The plans reflect how geothermal is being recognized as a growing carbon-free energy source in the country, and how Meta is committed to clean energy initiatives.

“The U.S. has seen unprecedented growth in demand for energy as our economy grows, the manufacturing sector booms thanks to the Biden-Harris Administration’s Investing in America agenda, and new industries like AI expand,” U.S. Energy Deputy Secretary David Turk says. “The Administration views this increased demand as a huge opportunity to add more clean, firm power to the grid and geothermal energy is a game-changeras we work to grow our clean power supply.”

Sage's technology — called Geopressured Geothermal System — works deep in the earth to develop energy storage and geothermal baseload power.

“Meta thanks the Department of Energy’s leadership on promoting and supporting the exploration of new energy sources like geothermal," Urvi Parekh, head of renewable energy at Meta, says. "That leadership supports Meta’s goal to enable the addition of reliable, affordable, and carbon-free power to the grid with this geothermal energy deal. We are excited to partner with such an innovative company like Sage Geosystems that is a proven leader in geothermal development on this project and beyond.”

Sage recently teamed up with a utility provider for an energy storage facility in the San Antonio metro area to build its three-megawatt EarthStore facility.

The company is also working on an exploratory geothermal project for the Army’s Fort Bliss post in Texas, which is the third U.S. Department of Defense geothermal initiative in the Lone Star State.

Houston-based geothermal energy startup Sage Geosystems has teamed up with a utility provider for an energy storage facility in the San Antonio metro area.

The three-megawatt EarthStore facility will be on land controlled by the San Miguel Electric Cooperative, which produces electricity for customers in 47 South Texas counties. The facility will be located in the town of Christine, near the cooperative’s coal-fired power plant.

Sage says its energy storage system will be paired with solar energy to supply power for the grid operated by the Electric Reliability Council of Texas (ERCOT). The facility is set to open later this year.

“Once operational, our EarthStore facility in Christine will be the first geothermal energy storage system to store potential energy deep in the earth and supply electrons to a power grid,” Cindy Taff, CEO of Sage Geosystems, says in a news release.

The facility is being designed to store geothermal energy during six- to 10-hour periods.

“Long-duration energy storage is crucial for the ERCOT utility grid, especially with the increasing integration of intermittent wind and solar power generation,” says Craig Courter, CEO of the San Miguel Electric Cooperative.

hot new recruits

Two clean energy companies in Houston have been recruited for geothermal projects at U.S. military installations.

Fervo Energy is exploring the potential for a geothermal energy system at Naval Air Station Fallon in Nevada.

Meanwhile, Sage Geosystems is working on an exploratory geothermal project for the Army’s Fort Bliss post in Texas. The Bliss project is the third U.S. Department of Defense geothermal initiative in the Lone Star State.

“Energy resilience for the U.S. military is essential in an increasingly digital and electric world, and we are pleased to help the U.S. Army and [the Defense Innovation Unit] to support energy resilience at Fort Bliss,” Cindy Taff, CEO of Sage, says in a news release.

A spokeswoman for Fervo declined to comment.

Andy Sabin, director of the Navy’s Geothermal Program Office, says in a military news release that previous geothermal exploration efforts indicate the Fallon facility “is ideally suited for enhanced geothermal systems to be deployed onsite.”

As for the Fort Bliss project, Michael Jones, a project director in the Army Office of Energy Initiatives, says it’ll combine geothermal technology with innovations from the oil and gas sector.

“This initiative adds to the momentum of Texas as a leader in the ‘geothermal anywhere’ revolution, leveraging the robust oil and gas industry profile in the state,” says Ken Wisian, associate director of the Environmental Division at the U.S. Bureau of Economic Geology.

The Department of Defense kicked off its geothermal initiative in September 2023. Specifically, the Army, Navy, and Defense Innovation Unit launched four exploratory geothermal projects at three U.S. military installations.

One of the three installations is the Air Force’s Joint Base San Antonio. Canada-based geothermal company Eavor is leading the San Antonio project.

Another geothermal company, Atlanta-based Teverra, was tapped for an exploratory geothermal project at the Army’s Fort Wainwright in Alaska. Teverra maintains an office in Houston.

University of Houston-founded company secures $2.5M in NIH grant funding

all in the timing

You could say that the booming success of Houston biotech company CellChorus owes very much to auspicious TIMING. Those six letters stand for Time-lapse Imaging Microscopy In Nanowell Grids, a platform for dynamic single-cell analysis.

This week, CellChorus announced that the company, along with The University of Houston, has been awarded up to $2.5 million in funding from the National Center for Advancing Translational Sciences (NCATS) at the National Institute of Health. A $350,000 Phase I grant is already underway. Once predetermined milestones are achieved, this will lead to a two-year $2.1 million Phase II grant.

The TIMING platform was created by UH Single Cell Lab researchers Navin Varadarajan and Badri Roysam. TIMING generates high-throughput in-vitro assays that quantitatively profile interactions between cells on a large scale, particularly what happens when immune cells confront target cells. This has been especially useful in the realm of immuno-oncology, where it has demonstrated its power in designing novel therapies, selecting lead candidates for clinical trials and evaluating the potency of manufactured cells.

“By combining AI, microscale manufacturing and advanced microscopy, the TIMING platform yields deep insight into cellular behaviors that directly impact human disease and new classes of therapeutics,” says Rebecca Berdeaux, chief scientific officer at CellChorus. “The generous support of NCATS enables our development of computational tools that will ultimately integrate single-cell dynamic functional analysis of cell behavior with intracellular signaling events.”

Houston’s CellChorus Innovation Lab supports both the further development of TIMING and projects for early-access customers. Those customers include top-25 biopharmaceutical companies, venture-backed biotechnology companies, a leading comprehensive cancer center and a top pediatric hospital, says CEO Daniel Meyer.

CellChorus’s publications include papers written in collaboration with researchers from the Baylor College of Medicine, Houston Methodist, MD Anderson, Texas Children’s Hospital, the University of Texas and UTHealth in journals including Nature Cancer, Journal of Clinical Investigation and The Journal for ImmunoTherapy of Cancer.

The new Small Business Technology Transfer (STTR) award will specifically support the development of a scalable integrated software system conceived with the goal of analyzing cells that are not fluorescently labeled. This label-free analysis will be based on new AI and machine learning (ML) models trained on tens of millions of images of cells.

“This is an opportunity to leverage artificial intelligence methods for advancing the life sciences,” says Roysam. “We are especially excited about its applications to advancing cell-based immunotherapy to treat cancer and other diseases.”

The Houston-born-and-bred company couldn’t have a more appropriate home, says Meyer.

“Houston is a premier location for clinical care and the development of biotechnology and life sciences technologies. In particular, Houston has established itself as a leader in the development and delivery of immune cell-based therapies,” the CEO explains. “As a spin-out from the Single Cell Lab at the University of Houston, we benefit from working with world-class experts at local institutions.”

In May, the company received a similar $2.5 million SBIR grant from NCATS at the NIH. Also this summer, CellChorus's technology was featured in Nature Cancer.

Bridging the skills gap: How recent college grads can help address urgent staffing needs

guest column

With the current low unemployment rate, locating seasoned and talented staffers who require minimal training is no small task, especially within the high-tech sector. At the same time, college graduates are hungry for new opportunities. In fact, according to the Federal Reserve Bank of St. Louis, many new workforce members are currently underemployed. Approximately 4 in 10 are working in a job that does not utilize the skills they recently obtained on a college campus.

On the employer side, there’s the fear of excessive onboarding needs. On top of that, many hiring managers are afraid that recently trained staffers will simply move on to a new opportunity in a few short years or even months.

But when faced with multiple open positions, is it worth taking the chance on the newest members of the workforce? Here’s some advice on how to successfully navigate the current hiring atmosphere, where college graduates may play a big role in combatting staffing shortages.

Consider culture fit

Hard skills are always important. But at the same time, recognize bright and energetic applicants equipped with a baseline of strong knowledge also tend to be rapid learners. These individuals can often get up to speed quickly as long as they receive the appropriate level of training and mentoring over their first few months on the job. In short, there are many cases where hard skills can be taught.

But how about soft skills?

Identifying candidates who understand and appreciate the company’s culture is a separate but critically important issue. When considering whether to bring an individual on board, be sure to assess all of their compatibilities as well. Often, some extra training for an employee who already values and appreciates the company environment results in a staff member who will stay with and benefit the organization for many years to come.

Look for transferable skills

In the current highly competitive hiring atmosphere, it can be difficult to locate candidates with skills that perfectly align with the needs of open positions. Therefore, it’s important for HR staff and hiring managers to consider transferrable skills. While an individual candidate may not be familiar with a particular software solution, do they have any experience that suggests they are well-equipped to navigate relatively similar systems? Be sure to closely review resumes and CVs that might reveal these hidden strengths. In addition, make certain your list of candidate interview questions is crafted to elucidate this kind of information. Remember that recent college graduates often lack significant interview experience. As a result, you may need to pose specific questions that get to the heart of the information you are seeking. For example, you might ask a candidate to relay past experiences where they needed to learn a new skill or solve a complex problem rapidly. This helps identify whether they can navigate new waters in the workplace or whether they can translate previously held skills into new ones.

Benefits of in-house development programs

Skilled employee shortages tend to surface repeatedly. Even if you don’t have any openings right now, things can change rapidly in a matter of months or even weeks. Because this is the case - especially in the technology sector - consider launching internal training programs that help recent hires learn new skills or sharpen older ones. One option would be in-house training by a skilled staffer as part of the new employee onboarding process. Other possibilities include online learning sessions or a partnership with a local college. Training programs can also be launched to help longtime employees learn new skills as emerging, modernized systems are introduced into the workplace, benefitting the company’s entire workforce.

Track new employee progress

All new employees — whether they are recent college grads or more established members of the workforce - can benefit greatly from a performance review process that features frequent check-ins throughout the initial stages of employment. Supervisors should try to meet weekly or biweekly with new staff during their onboarding process to assess their progress in learning new skills, while identifying needs for additional training. Managers should also regularly communicate with mentors assigned to new employees to ensure skills are developed in a positive learning atmosphere.

In addition to any perceived hurdles, companies should also consider the many benefits of hiring recent college graduates. In some cases, they might bring with them new insights and experiences with emerging technologies. They often arrive with an eagerness to learn and they can introduce ideas and energy, creating increased enthusiasm in the workplace.

When it comes to filling vacant positions, there are many cases where considering recent college graduates can greatly benefit your company. A little training and mentoring can often go a long way and sometimes, taking a chance on a yet unproven, but smart and energetic candidate can land a professional who will benefit the organization for years or even decades to come.
