Expanding on its partnership with the United States Department of Defense's Defense Innovation Unit, Sage Geosystems has been selected to conduct geothermal project development initiatives at Naval Air Station in Corpus Christi.

Along with the Environmental Security Technology Certification Program, Sage will provide its proprietary Geopressured Geothermal Systems technology, will be able to evaluate the potential for geothermal baseload power generation to provide clean and consistent energy at the Naval Air Station base.

“We’re pleased to expand our partnership with the DOD at NAS Corpus Christi to demonstrate the advantages of geothermal technology for military energy independence,” Cindy Taff, CEO of Sage Geosystems, says in a news release.

Sage is also conducting initiatives at Fort Bliss and has completed an analysis at the Ellington Field Joint Reserve Base. The analyses could “pave the way for expanding geothermal energy solutions across additional U.S. military installations,” according to Sage.

The company’s proprietary technology works by leveraging hot dry rock, which is a more abundant geothermal resource compared to traditional hydrothermal formations, and it provides energy resilience for infrastructures. In addition, Sage is building a 3 megawatt commercial EarthStore geothermal energy storage facility in Christine, Texas, which is expected to be completed by December. Sage also announced a partnership with Meta Platforms. With Meta Platforms, Sage will deliver up to 150 megawatt of geothermal power generation east of the Rocky Mountains.

The Naval Air Station Corpus Christi is considered a critical training and operations hub for the U.S. Navy, and the partnership with Sage shows the Navy's commitment to achieving net-zero carbon emissions by 2045. Sage’s technology will be assessed for its ability to create a microgrid, which can reduce reliance on the utility grid and ensure power supply during outages.

“As we advance our Geopressured Geothermal Systems, we see tremendous potential to not only provide carbon-free power, but also strengthen the operational capabilities of U.S. military installations in an increasingly digital and electric world,” Taff adds.

In September, the Air Force awarded Sage a grant of $1.9 million in a first-of-its kind contract to determine whether a power plant using Geopressured Geothermal Systems is able to generate clean energy needed for a base to achieve energy resilience.

Rice University innovators claim prizes across health care, energy research

big wins

Undergraduate students from Rice University were awarded the top prize in a health innovation challenge.

Design by Biomedical Undergraduate Teams (DEBUT) Challenge, which is organized by the National Institutes of Health (NIH) and the non-profit organization VentureWell, selected medical device team UroFlo as its winner, claiming the $20,000 prize. The technology, a continuous bladder irrigation system, was recognized for its potential to revolutionize post-operative care and improve patient outcomes.

The winning team from Rice consists of 2024 bioengineering graduates Anushka Agrawal, Sahana Prasanna, Robert Heeter, Archit Chabbi, Kevin Li, and Richard Chan. The UroFlo system provides care to patients after surgery and reduces the burden on health care professionals by implementing state-of-the-art sensors and machine learning algorithms with a touchscreen user interface. This helps with data collection, processing and visualization. UroFlo promises to enhance the management of urinary tract infections (UTIs) and help prevent blood clots.

“We have learned so much from this process and we are really proud of what we have accomplished,” says Chabbi in a news release. “It’s truly rewarding to know that our work can impact patients’ experience and help improve quality of care. Over the many hours we spent working in the Oshman Engineering Design Kitchen (OEDK) at Rice, we’ve not only developed an amazing set of skills, but have also forged really strong connections with one-another and the nearby medical community at the Texas Medical Center.”

The award will be presented on Oct. 25 in Baltimore during the annual Biomedical Engineering Society (BMES) conference.

UroFlo was also with first place in the Johns Hopkins Healthcare Design Competition in the Post-Surgical Infection Management category; first place in the American Society for Artificial Internal Organs Student Design Competition; “Best Medical Device Technology Award” in the 2024 Huff Engineering Design Showcase and competition held by the OEDK; “Outstanding Bioengineering Design Project,” Rice Department of Bioengineering; “Best Presentation” in the Texas Children’s Hospital Surgical Research Day; finalist and “Best Engineering Project” in Rice’s 2024 Shapiro Research Showcases; and semi-finalist in the H. Albert Napier Rice Launch Challenge. UroFlo will continue after Rice, as the project will be developed further.

“We are all very passionate about biomedical engineering, and dedicated and committed to making a difference” Chan said in a news release. “We actually decided to continue to develop UroFlo after our graduation from Rice a few months ago with the hope of improving our innovative solution for urological care.”

In other news, Rice University’s Naomi Halas won $7.5 million over five years from the United States Department of Defense (DOD) Air Force Office of Scientific Research (AFOSR) with her project proposal Multidisciplinary University Research Initiative (MURI) for her project titled “Combining Nonequilibrium Chemistries with Atomic Precision,” which competed in the category “plasmon-controlled single-atom catalysis.”

“Combining Nonequilibrium Chemistries with Atomic Precision” addressed the need for more energy-efficient and less protocol-intensive chemical processes that involve using light to drive chemical reactions and single-atom “reactors” to catalyze chemical reactions that are nearly 100 percent specific in terms of reaction products.

Plasmons work when they make metal nanoparticles act like antennas, and certain designed reactor sites on their surfaces can then carry out chemical reactions at a fraction of the “energy expenditure of conventional industrial catalysts” according to a news release.

Rice University and Baylor College of Medicine have also received $2.8 million in funding from the National Heart, Lung, and Blood Institute (NHLBI) for their research on reducing inflammation and lung damage in acute respiratory distress syndrome (ARDS) patients.

“Cell Based Immunomodulation to Suppress Lung Inflammation and Promote Repair,” will be co-led byRice’s Omid Veiseh, a professor of bioengineering and faculty director of the Rice Biotech Launch Pad, and professor of surgery at Baylor Ravi Kiran Ghanta. They will develop a new translational cell therapy platform “ to allow a better local administration of cytokines to the lungs in order to suppress inflammation and potentially prevent lung damage in ARDS patients” according to a news release.

2 Houston startups selected by US military for geothermal projects

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.

Houston health tech innovator collaborates on promising medical device funded by DOD

team work

The United States Department of Defense has awarded a grant that will allow the Texas Heart Institute and Rice University to continue to break ground on a novel left ventricular assist device (LVAD) that could be an alternative to current devices that prevent heart transplantation and are a long-term option in end-stage heart failure.

The grant is part of the DOD’s Congressionally Directed Medical Research Programs (CDMRP). It was awarded to Georgia Institute of Technology, one of four collaborators on the project that will be designed and evaluated by the co-investigator Yaxin Wang. Wang is part of O.H. “Bud” Frazier’s team at Texas Heart Institute, where she is director of Innovative Device & Engineering Applications Lab. The other institution working on the new LVAD is North Carolina State University.

The project is funded by a four-year, $7.8 million grant. THI will use about $2.94 million of that to fund its part of the research. As Wang explained to us last year, an LVAD is a minimally invasive device that mechanically pumps a person’s own heart. Frazier claims to have performed more than 900 LVAD implantations, but the devices are far from perfect.

The team working on this new research seeks to minimize near-eventualities like blood clot formation, blood damage, and driveline complications such as infection and limitations in mobility. The four institutions will try to innovate with a device featuring new engineering designs, antithrombotic slippery hydrophilic coatings (SLIC), wireless power transfer systems, and magnetically levitated driving systems.

Wang and her team believe that the non-contact-bearing technology will help to decrease the risk of blood clotting and damage when implanting an LVAD. The IDEA Lab will test the efficacy and safety of the SLIC LVAD developed by the multi-institutional team with a lab-bench-based blood flow loop, but also in preclinical models.

“The Texas Heart Institute continues to be a leading center for innovation in mechanical circulatory support systems,” said Joseph G. Rogers, MD, the president and CEO of THI, in a press release.

“This award will further the development and testing of the SLIC LVAD, a device intended to provide an option for a vulnerable patient population and another tool in the armamentarium of the heart failure teams worldwide.”

If it works as hypothesized, the SLIC LVAD will improve upon current LVAD technology, which will boost quality of life for countless heart patients. But the innovation won’t stop there. Technologies that IDEA Lab is testing include wireless power transfer for medical devices and coatings to reduce blood clotting could find applications in many other technologies that could help patients live longer, healthier lives.

NASA signs 2 public-private lease agreements at Houston campus to promote human space research

ready to launch

NASA and the American Center for Manufacturing and Innovation signed an agreement Thursday, Feb. 29 to lease underutilized land in a 240-acre Exploration Park at the agency's Johnson Space Center in Houston. The deal comes after a similar lease with the Texas A&M University System.

ACMI will enable the development of facilities to enable commercial and defense space manufacturing, while A&M reports that it will develop a facility for human spaceflight research and development.

These two public/private lease agreements allow industry and academia to use NASA Johnson land to create facilities for a collaborative development environment that increases commercial access and enhances the United States' commercial competitiveness in the space and aerospace industries.

“For more than 60 years, NASA Johnson has been the hub of human spaceflight,” NASA Johnson Director Vanessa Wyche says in a news release. “Exploration Park will be the next spoke in the larger wheel of a robust and durable space economy that will benefit not only exploration of the Moon, Mars and the asteroids, but all of humanity as the benefits of space exploration research roll home to Earth.”

Calling it the Space Systems Campus, ACMI plans to incorporate an applied research facility partnered with multiple stakeholders across academia, state and local government, the Department of Defense and regional economic development organizations.

"This Space Systems Campus will be a significant component within our objectives for a robust and durable space economy that will benefit not only the nation's efforts to explore the Moon, Mars and the asteroids, but all of humanity as the benefits of space exploration research roll home to Earth," Wyche says of the ACMI deal.

As the home of Mission Control Center for the agency's human space missions, astronaut training, robotics, human health and space medicine, NASA Johnson leads the way for the human exploration. Leveraging this unique role and location, Exploration Park will play a key role in helping the human spaceflight community attain U.S. goals for the commercialization and development of a robust space economy by creating an infrastructure that fosters a multi-use environment where academic researchers, aerospace companies and entrepreneurs can collaborate with NASA. Exploration Park will create an infrastructure that allows for a multi-use space hardware development environment, where academic researchers, aerospace companies and entrepreneurs can collaborate on space exploration's greatest challenges.

"ACMI Properties will develop this Campus to serve the needs of our future tenants, aerospace industry, the Department of Defense and other significant stakeholders that comprise our ecosystem approach," said Simon Shewmaker, head of development for ACMI Properties. "Our aim is to support human spaceflight missions for the next 40 years and beyond."

NASA issued an announcement for proposals for use of the undeveloped and underutilized land near Saturn Lane on June 9, 2023, and has just completed negotiations with ACMI to formalize the lease agreement. The parcel is outside of Johnson's controlled access area and adjacent to its main campus. NASA will lease the land for 20 years with two 20-year extension options, for a potential of up to 60 years.

In the coming years, NASA and its academic, commercial, and international partners will see the completion of the International Space Station Program, the commercial development of low Earth orbit, and the first human Artemis campaign missions establishing sustainable human presence on the Moon in preparation for human missions to Mars.

Johnson already is leading the commercialization of space with the commercial cargo and crew programs and private astronaut missions to the space station. The center also is supporting the development of commercial space stations in low Earth orbit, and lunar-capable commercial spacesuits and lunar landers that will be provided as services to both NASA and the private sector to accelerate human access to space. Through the development of Exploration Park, the center will broaden the scope of the human spaceflight community that is tackling the many difficult challenges ahead.

Houston software startup is tapping into the military sector with VR training tools

Houston innovators podcast episode 127

For years, the idea of virtual and augmented reality has been growing in use and popularity from a consumer perspective. VR art experiences are popping up in every major city, and Snapchat and Instagram filters are flooding our phone screens daily. But one Houston company had the foresight to tap this tech in the business world.

"Our real mission around HTX Labs was to take what we felt was amazing technology — virtual reality, augmented reality, extended reality, and immersive technology in general — and take it from a primary consumer focus into enterprise," Scott Schneider says on this week's episode of the Houston Innovators Podcast.

A VR headset is different from your usual office appliance — it's not a printer or a desktop computer. So, addressing this technology and how companies deal with network security and identity management — plus the software designing itself — has been HTX Labs' bread and butter since it was founded in 2017.

"It's always been around how do we elevate training — and that's really been our mission for the past five years," Schneider says.

Over the years, the startup has had the opportunity to enter a new sector, and it's represented a pretty big pivot for the company. Now, 95 percent of HTX Labs's focus is on the Department of Defense.

"Around 2018, we were approached by the U.S. Air Force," Schneider says. "Three and a half years later, we are fully engaged with the DoD – Air Force, Navy, Army. Our big focus is around training aircraft pilots and maintainers — if you fly them or you fix them, they are using our technology."

HTX Labs has tripled its team over the past few years, and is looking to hire another 20 people to support its growth — specifically looking for sales, business development, and operational positions.

"In 2021, we were all about building capability and building our platform," Schneider says, "and 2022 is all about adoption. It's a land grab out there for doing what we're doing. We're trying to drive adoption within the government and outside in the commercial and private sector."

Schneider shares more on what he's focused on this year and how HTX Labs has grown alongside the Houston innovation ecosystem on the podcast episode. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
