Overheard: Houston's top energy transition founders explain their biggest challenges

Houston Innovation Awards

From finding funding to navigating the pace of traditional oil and gas company tech adoption, energy transition companies face their fair share of challenges.

This year's Houston Innovation Awards finalists in the Energy Transition category explained what their biggest challenge has been and how they've overcome it. See what they said below, and make sure to secure your tickets to the Nov. 14 event to see which of these finalists win the award.

"The evolving nature of the energy industry presents opportunities to solve some of our industry's greatest challenges. At Amperon we help optimize grid reliability and stability with the power of AI demand forecasting."

— Sean Kelly, CEO of Amperon, an AI platform powering the smart grid of the future

"The biggest challenge in leading an energy transition-focused startup has been balancing the urgency for sustainable solutions with the slow pace of change in traditional industries like oil and gas. Many companies are cautious about adopting new technologies, especially when it comes to integrating sustainability initiatives. We overcame this by positioning our solutions not just as environmentally friendly, but as tools that improve safety, efficiency, and cost savings. By aligning our value proposition with their operational goals and demonstrating real, measurable benefits, we were able to gain traction and drive adoption in industries that are traditionally resistant to change."

— Dianna Liu, CEO of ARIXTechnologies, an integrated robotics and data analytics company that delivers inspection services through its robotics platforms

"Scaling up production of hard tech is a major challenge. Thankfully, we recruited top-notch talent with experience in technology scale-up and chemical processes. In addition, we've begun building partnerships with some of the world's largest chemical manufacturers in our space who are excited to be a part of our journey and could rapidly accelerate our go to market strategy. We have significant demand for our product as early as 2025, so partnering with these companies to scale-up will bring our technology to market years ahead of doing it alone."

— Matthew Dawson, CEO of Elementium Materials, a battery technology with liquid electrolyte solutions

"Our pyrolysis reactor is a proprietary design that was developed during Covid. We ran simulations to prove that it works, but it was not easy to test it in a pilot facility, let alone scaling it up. We managed ... to run our pilot plant studies, while working with them remotely. We proved that our reactor worked and produced high quality products. Later, we built our own pilot plant R&D facility to continue running tests and optimizing the process. Then, there was the challenge of scaling it up to commercial size. ... We put together a task force of four different companies to come together to design and build this complex reactor in record time."

— Vibhu Sharma, CEO of InnoVent Renewables, a startup with proprietary continuous pyrolysis technology that converts waste tires, plastics, and biomass into valuable fuels and chemicals

"Energy storage and geothermal power generation are capital-intensive infrastructure projects, requiring investors with a deep commitment and the patience in terms of years to allow the technology to be developed and proven in the field. One challenge is finding that niche of investors with the vision to join our journey. We have succeeded in raising our $30 million series A with these types of investors, whom we’re confident will continue the journey as we scale."

— Cindy Taff, CEO of Sage Geosystems, an energy company focused on developing and deploying advanced geothermal technologies to provide reliable power and sustainable energy storage solutions regardless of geography

"The biggest challenge we've faced has been to bring together massive independent power producers on one side who are investing hundreds of millions of dollars into grid infrastructure with multi- national tech giants on the other that don't have experience working much with energy storage. As a startup with only four employees, gaining credibility with these players was critical. We overcame this hurdle by becoming the preeminent thought leader on storage emissions, through publishing white papers, discussing the issues on podcasts, and (more)."

— Emma Konet, CTO of TierraClimate, a software provider that helps grid-scale batteries reduce carbon emissions

Bairitone Health

Bairitone Health is bringing anatomy imaging for sleep apnea to the home environment. The company's platform maps users' anatomy during natural sleep using a facial patch to determine the root cause of airway obstruction. It then offers effective therapies for each patient.

The company was founded in 2022 in the Texas Medical Center's Biodesign program by CEO Meagan Pitcher, CTO Onur Kilic and chief medical officer Britt Cross. It was a member of Activate Houston's inaugural cohort and has participated in numerous accelerators and incubators. The company raised an oversubscribed seed round for $2.4 million earlier this year and received Breakthrough Device Designation from the Food and Drug Administration in April.

InformAI Inc.

InformAI Inc. develops fit-to-purpose AI solutions for the clinical setting. Its RadOncAI product recently received FDA 510(k) clearance. The product uses AI to create a first-pass radiation therapy dose plan for complex head and neck cancers in an effort to eliminate bottlenecks in radiation planning and ultimately cancer treatment. The company has also developed AI products for sinus disease detection and 3D organ reconstruction.

CEO Jim Havelka founded the company in 2017. It is participating in the Mayo Clinic Accelerate Platform. It has raised about $4 million in seed funding and has received numerous non-dilutive grants from the National Science Foundation, the National Institutes of Health and the Cancer Prevention and Research Institute of Texas. The company shared in its application that it plans to launch a Series A fundraising round and submit an FDA 510K application for its organ reconstruction product, Voluquant, by the end of 2026.

Prana Surgical

Prana Surgical is developing a minimally invasive surgical platform for small, hard-to-reach lung nodules that may be cancerous. The company's Prana System cleared U.S. Food and Drug Administration (FDA) approval earlier this year.

Prana Surgical was originally founded as Prana Thoracic in 2022. It has participated in numerous accelerators, including the Texas Medical Center Innovation Accelerator in 2023 and the IGNITE Health accelerator in 2022. It raised $6 million in Series A funding rounds in 2023 and 2024 , with a Series B currently ongoing.

CEO Matthew Kuhn, who previously founded Taurus Vascular, founded Skybound last year. The company emerged from stealth in January after raising a $1.25 million Series A round. It plans to advance its lead dual-use platform into critical preclinical validation in November, the company shared in its application. It is currently raising a $25 million Series A round and is pursuing federal research partnerships with DARPA and ARPA-H.

Generation Park lands new facility to scale xeno-organ production

Organ innovation

Maryland-based United Therapeutics Corp. has opened a new 77,448-square-foot facility to manufacture xeno-organs in Northeast Houston’s growing biotech hub, Generation Park.

The new Houston location is United Therapeutics’ third Designated Pathogen-Free (DPF) site, named for transplant pioneers Dr. Bartley P. Griffith and Dr. Robert A. Montgomery. The company says the new facility will enable it to scale commercial production of its xeno-organs once they receive regulatory approval.

An existing DPF facility in Virginia is supporting clinical trials for the xeno-organs, and a third site in Minnesota will also focus on commercialization with the Houston site, according to the company.

Xeno-organs are organs taken from a non-human animal source and transplanted, implanted or infused into a human recipient.

Currently, United Therapeutics is advancing clinical trials to support a Biologics License Application with the U.S. Food and Drug Administration for its investigational-stage xenotransplantation, UKidney, UThymoKidney and UHeart products. The products all involve working with the genes from humans and pigs.

In 2025, Chron.com reported the company was working to construct an estimated $96 million facility to breed genetically engineered animals. Head of investor relations at United Therapeutics Dewey Steadman told the Houston Business Journal in 2025 that the pigs’ DNA will be edited. In November 2024, a 53-year-old woman in Alabama received a transplanted kidney from UKidney that had 10 gene edits. She had the transplant removed in April 2025, after her body rejected it.

The Dr. Bartley P. Griffith and Dr. Robert A. Montgomery Xenograft Production Facility requires a “strictly controlled, biosecure barrier environment, including air filtration, filtered water, filtered feed supplies, and state-of-the-art decontamination entryways,” according to the company. Being pathogen-free means it includes calibrated air and water conduits to support the transplantability of xenograft products and to prevent contamination. For energy considerations, the building also features solar arrays.

“With our third xenograft production facility now open and clinical trials underway, United Therapeutics is moving closer to its goal of providing transplantable organs to the people who need them,” Martine Rothblatt, chairperson and CEO of United Therapeutics, said in a news release. “It is fitting that this facility is named for Dr. Griffith and Dr. Montgomery, whose first-in-human surgeries turned xenotransplantation from a theoretical possibility into a clinical reality.”

The facility, which wrapped construction in August, is located at 11848 Common Dock Dr. in Generation Park, which will house manufacturing sites for pharmaceutical heavyweights Bristol Myers Squibb and Eli Lilly. Last fall, Eli Lilly tapped Generation Park for its $6.5 billion manufacturing plant, and Bristol Myers Squibb made a $2.3 billion investment in August to bring its state-of-the-art site to the master-planned commercial district.

Elon Musk's SpaceX reports profit as AI and satellite businesses booms

Booming Business

SpaceX reported a bigger quarterly profit than expected on Tuesday, October 20, as its satellite communications and artificial intelligence businesses boomed.

The company, run by Elon Musk, posted a profit for the three months through September 2026 of $4.4 billion, or 35 cents per share, reversing a year-ago loss and easily topping Wall Street's expectations. Revenue soared to $14.6 billion, up 161%.

On a conference call with analysts, Musk suggested a merger with his electric car company Tesla might be in the works, something that has been rumored for months. He said both companies formed “special committees” of independent directors to discuss the issue, though he played down the chances of an imminent deal.

“Some people out there assume that a SpaceX and Tesla merger is a certainty,” he said. “I think that would be overstating it.”

The AI business became SpaceX's largest by revenue in the third quarter, although the Starlink satellite service remains the biggest profit generator.

“They beat across all metrics and the Starlink business looks to be accelerating,” said Dan Ives, an analyst at Yorkville Ives. “This is just what (Wall) Street wanted.”

The stock rose 7.5% in after-hours trading.

Musk also told analysts that for next month's launch of its Starship rocket, SpaceX will attempt to grab both the booster and ship with mechanical arms upon return to base, a key step toward demonstrating it can reuse the massive spacecraft.

“The only way that we can extend consciousness beyond Earth on a sustained basis is with a fully reusable orbital launch vehicle,” Musk said, calling the attempt, if successful, “a massive technology milestone.”

SpaceX hopes to get Starship on a regular launch pattern in preparation for NASA's upcoming lunar missions.

The company already has huge contracts with the federal government, and House Democrats have called for investigations into those contracts and Musk’s work with the Department of Government Efficiency. Musk has spent $276 million since July in support of Republican candidates.

In a filing for its initial public offering in June, SpaceX warned that a change in control of Congress could have a “material and adverse impact on our growth and competitive position.”

Musk recently drew criticism from politicians in Washington after speeds for a military version of SpaceX's satellite communications service were slowed for Ukraine following President Donald Trump's deal to get more diesel oil from Russia amid a push to end the war. The Wall Street Journal reported Tuesday that it was Musk who ordered the slowdown, impeding Ukraine’s use of drones along the front. SpaceX did not immediately respond to an Associated Press request for comment on the Journal story.

Both Trump and Musk have denied responsibility for the slowdown.

As midterm elections near, Musk on Monday promised to give one share of SpaceX to “every kid in America” next year, though he provided no details on how the distribution would be carried out. With communities nationwide protesting the construction of large data centers and concerns about AI safety, AI companies are trying to build goodwill. Anthropic pledged to commit 5% of its shares to a new “public benefit” fund.

SpaceX shares have been under pressure over concerns that the company was spending too much on major projects to compete with rivals such as Anthropic. The company said capital expenditures totaled $19.6 billion last quarter, nearly triple the figure from a year earlier, and it forecast spending would grow to $35 billion to $40 billion in the current quarter.

Shares of SpaceX closed Tuesday at $147.79, down from a peak near $201 after its IPO, which made Musk the world’s first trillionaire at the time. But the share prices for SpaceX and Tesla have since dropped, reducing his net worth to $925 billion, according to Forbes magazine.

Tesla reports third-quarter financial results Wednesday. Last week, Tesla unveiled a new Roadster sports car that in some versions may include thrusters allowing it to briefly fly using SpaceX technology — though experts say anything usable for drivers is a long shot.
