    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

    At last year's awards program, Cemvita Factory's co-founders, Tara and Moji Karimi, accepted the award for the Green Impact Business category. This year, Moji Karimi served as a judge

    Houston innovator on the impact of facade enhancement on the energy transition

    guest column

    Imagine a world where outdated building facades transform overnight into modern marvels without the chaos of construction or the burden of exorbitant costs.

    In the recent podcast episode on Energy Tech Startups, Anas Al Kassas, the CEO of INOVUES, unveils a groundbreaking technology that promises just that. This isn't just about a facelift; it's about revolutionizing energy efficiency, embracing smart-class innovations, and redefining the aesthetics of urban landscapes.


    The Advantages of Facade Technology

    One of the key advantages Al Kassas highlighted was the ability to significantly reduce both the cost and environmental impact of upgrading building facades. Al Kassas explained that by utilizing INOVUES' technology, the existing systems can be updated and improved without the need for removing or discarding the windows. This approach not only saves on material costs but also avoids disruption during installation. Additionally, the fast installation process and lower labor costs further contribute to the overall cost-effectiveness of the solution.

    The Role of Design Aesthetics in Building Upgrades

    While energy efficiency is a primary driver for building upgrades, Al Kassas emphasized the importance of design aesthetics in the commercial real estate market. He explained that modernizing the appearance of older buildings, which may still perform well but suffer from outdated perceptions, can attract more tenants and make them more competitive. With INOVUES' solution, building owners have the opportunity to improve the aesthetics of their facades by incorporating the latest glass technologies, colors, and frit patterns (translucent patterns on glass). This not only enhances the building's appearance but also contributes to glare reduction and customization options for different tenants' needs.

    The Potential for Rentable Facades

    During the conversation, Al Kassas speculated about the potential for rentable facades powered by INOVUES' technology. Just as Apple offers an upgrade plan for its devices, this concept proposes a similar model for building owners to continually incorporate the latest technologies every few years. By avoiding upfront costs and providing immediate benefits such as lower energy bills, improved tenant satisfaction, and a more sustainable building, this rentable facade approach could revolutionize the industry and make energy-efficient upgrades more accessible for a wider range of buildings.

    The Current Funding Landscape and Future Growth

    INOVUES' journey in securing funding, as discussed in the podcast, sheds light on the challenges faced by energy tech startups. The CEO highlighted the importance of timing and identifying the right investors who share the vision and understand the industry landscape. Despite the difficulties, INOVUES has successfully raised capital, including participation from a multinational building technology company. The company's next goal is to secure a series A funding round to scale their operations and expand their footprint in the market.

    INOVUES' technology represents a sustainable solution for upgrading building facades without the need for extensive removal or disruptions. The combination of energy efficiency, improved design aesthetics, and the potential for rentable facades showcases the versatility and value of the company's technology. As the demand for sustainable building solutions continues to grow, and regulatory changes support energy efficiency projects, INOVUES is poised to make a significant impact in the industry. By focusing on both environmental and economic benefits, they are positioning themselves as a key player in the energy tech startup landscape.

    patent progress

    A Houston company that retrofits windows with smart glass innovations to reduce energy use is celebrating a handful of patents across North America and China.

    INOVUES announced it secured several new patents from the United States Patent and Trademark Office, the Canadian Intellectual Patent Office, and the China National Intellectual Property Administration.

    “These newly awarded patents reinforce our commitment to innovation and position us as a trusted partner for investors and industry partners,” says Anas Al Kassas, INOVUES founder and CEO, in a news release.

    The company now has a total of four patents granted in the United States, Canada, and China, and four more patents pending in the United States, Canada, and the European Union. Additionally, INOVUES has trademark protection granted in the EU, United Kingdom, and China.

    INOVUES's unique window treatment — its Insulating Glass Retrofit (IGR) and Secondary Glass Retrofit (SWR) technologies — directly impacts the built environment. The process includes 70 percent fewer materials compared to traditional methods and building owners see a 40 percent reduction in reduction in energy consumption following installation.

    Last year, the company raised $2.75 million in venture funding. Kassas said at the time that the funding was slated o be used to scale up the team and identify the best markets to target customers, adding that he was looking for regions with rising energy rates and sizable incentives for companies making energy efficient changes.

    "We were able to now implement our technology in over 4 million square feet of building space — from Boston, Seattle, Los Angeles, New York City, Portland, and very soon in Canada," he said in a December episode of the Houston Innovators Podcast.

    3 Houston energy companies rank among most innovative startups in Texas

    report card

    Three Houston companies claimed spots on LexisNexis's 10 Most Innovative Startups in Texas report, with two working in the geothermal energy space.

    Sage Geosystems claimed the No. 3 spot on the list, and Fervo Energy followed closely behind at No. 5. Fintech unicorn HighRadius rounded out the list of Houston companies at No. 8.

    LexisNexis Intellectual Property Solutions compiled the report. It was based on each company's Patent Asset Index, a proprietary metric from LexisNexis that identifies the strength and value of each company’s patent assets based on factors such as patent quality, geographic scope and size of the portfolio.

    Houston tied with Austin, each with three companies represented on the list. Caris Life Sciences, a biotechnology company based in Dallas, claimed the top spot with a Patent Asset Index more than 5 times that of its next competitor, Apptronik, an Austin-based AI-powered humanoid robotics company.

    “Texas has always been fertile ground for bold entrepreneurs, and these innovative startups carry that tradition forward with strong businesses based on outstanding patent assets,” Marco Richter, senior director of IP analytics and strategy for LexisNexis Intellectual Property Solutions, said in a release. “These companies have proven their innovation by creating the most valuable patent portfolios in a state that’s known for game-changing inventions and cutting-edge technologies.We are pleased to recognize Texas’ most innovative startups for turning their ideas into patented innovations and look forward to watching them scale, disrupt, and thrive on the foundation they’ve laid today.”

    This year's list reflects a range in location and industry. Here's the full list of LexisNexis' 10 Most Innovative Startups in Texas, ranked by patent portfolios.

    1. Caris (Dallas)
    2. Apptronik (Austin)
    3. Sage Geosystems (Houston)
    4. HiddenLayer (Austin)

    Sage Geosystems has partnered on major geothermal projects with the United States Department of Defense's Defense Innovation Unit, the U.S. Air Force and Meta Platforms. Sage's 3-megawatt commercial EarthStore geothermal energy storage facility in Christine, Texas, was expected to be completed by the end of last year.

    Fervo Energy fully contracted its flagship 500 MW geothermal development, Cape Station, this spring. Cape Station is currently one of the world’s largest enhanced geothermal systems (EGS) developments, and the station will begin to deliver electricity to the grid in 2026. The company was recently named North American Company of the Year by research and consulting firm Cleantech Group and came in at No. 6 on Time magazine and Statista’s list of America’s Top GreenTech Companies of 2025. It's now considered a unicorn, meaning its valuation as a private company has surpassed $1 billion.

    Meanwhile, HighRadius announced earlier this year that it plans to release a fully autonomous finance platform for the "office of the CFO" by 2027. The company reached unicorn status in 2020.

    Tech entrepreneur turned climate investor is on a mission to monetize carbon removal

    now streaming

    The climate conversation is evolving — fast. It’s no longer just about emissions targets and net-zero commitments. It’s about capital, infrastructure, and execution at industrial scale.

    That’s exactly where Yao Huang operates. A seasoned tech entrepreneur turned climate investor, Yao brings sharp clarity to one of the biggest challenges in climate innovation: how do we fund and scale technologies that remove carbon without relying on goodwill or government subsidies?

    In this episode of the Energy Tech Startups Podcast, Yao sits down with hosts Jason Ethier and Nada Ahmed for a wide-ranging conversation that redefines how we think about decarbonization. From algae-based photobioreactors that capture CO₂ at the smokestack, to financing models that mirror real estate and infrastructure—not venture capital—Yao lays out a case for why the climate fight will be won or lost on spreadsheets, not slogans.

    Her message is as bold as it is practical: this isn’t about saving the planet for the sake of it. It’s about building profitable, resilient systems that scale. And Houston, with its industrial base and project finance expertise, is exactly the place to do it.

    The 40-Gigaton Challenge—and a Pandemic Pivot

    Yao’s entry into climate wasn’t part of a long-term plan. It was sparked by a quiet moment during the pandemic—and a book.

    Reading How to Avoid a Climate Disaster by Bill Gates, she came to two uncomfortable realizations:

    1. The people in power don’t actually have this figured out, and
    2. She would be alive to suffer the consequences.

    That insight jolted her out of the traditional tech world and into climate action. She studied at Stanford, surrounded herself with mentors, and began diving into early-stage climate deals. But she quickly realized that most of the solutions she was seeing were still years away from commercialization.

    So she narrowed her focus: no R&D moonshots, no science experiments—just deployable solutions that could scale now.

    Carbon Optimum: Where Algae Meets Infrastructure

    That’s how she found Carbon Optimum, a company using algae photobioreactors to remove CO₂ directly from industrial emissions. Their approach is both elegant and economic:

    • Install algae reactors next to major emitters like coal and cement plants.
    • Feed the algae with flue gas, allowing it to absorb CO₂ in a controlled system.
    • Harvest the algae and convert it into valuable commodities like bio-oils, fertilizer, and food ingredients.

    It’s a nature-based solution, enhanced by engineering.
    One acre of tanks can capture emissions and generate profit—without subsidies.

    “This is one of the few solutions I’ve seen that can scale profitably and quickly,” Yao says. “And we’re not inventing anything new—we’re just doing it better.”

    The Real Problem? It’s Capital, Not Carbon

    As an investor, Yao is blunt: most climate startups are misaligned with the capital markets.

    They’re following a tech startup playbook—built for SaaS, not steel. But building climate infrastructure requires a completely different approach: project finance, blended capital, debt structures, carbon credit integration, and regulatory incentives.

    “Climate tech is more like real estate or healthcare than software,” Yao explains. “You don’t raise six rounds of venture. You build a stack—grants, equity, debt, tax credits—and you structure your project like infrastructure.”

    It’s not just theory. It’s exactly how Carbon Optimum is expanding—through partnerships, offtake agreements, and real-world deployments. And it’s why she believes many climate startups fail: they don’t speak the language of finance.

    Houston’s Role in the Climate Capital Stack

    For Yao, Houston isn’t just a backdrop—it’s a strategic asset.

    The city’s deep bench of project finance professionals, commodity traders, lawyers, and infrastructure veterans makes it uniquely positioned to lead the deployment phase of climate solutions.

    “We’ve been calling it the wrong thing,” she says. “This isn’t just about climate—it’s an energy transition. And Houston knows how to build energy infrastructure at scale.”

    Still, she notes, the ecosystem needs to evolve. Less education, more execution. Fewer workshops, more closers.

    “Houston could be the epicenter of this movement—if we activate the right people and get the right projects over the line.”

    From Carbon Capture to Circular Economies

    The potential applications of Carbon Optimum’s algae platform go beyond carbon capture. Because the output—algae biomass—can be converted into:

    • Renewable oil
    • High-efficiency fertilizers (critical in today’s geopolitically fragile supply chains)
    • Food ingredients rich in protein and nutrients
    • Even biochar, a highly stable form of carbon sequestration

    It’s scalable, modular, and location-agnostic. In island nations, Yao notes, these systems can offer energy independence by turning waste CO₂ into local energy and fertilizer—without needing to import fuels or food.

    “It’s not just emissions reduction. It’s economic sovereignty through circular systems.”

    Doing, Not Just Talking

    One of Yao’s key takeaways for founders? Don’t waste time. Climate startups don’t have the luxury of trial-and-error cycles stretched over years.

    “Founders need to get real about what it takes to scale: talent, capital, storytelling, partnerships. If you’re not ready to do that, maybe you should be a CSO, not a CEO.”

    She also points out that founders don’t need to hire everyone—they need to tap the right networks. And in cities like Houston, those networks exist—if you know how to motivate them.

    “It takes a different kind of leadership. You’re not just raising money—you’re moving people.”

    Why This Episode Matters

    This conversation is for anyone who’s serious about scaling real solutions to the climate crisis. Whether you’re a founder navigating capital markets, an investor seeking return and impact, or a policymaker designing the frameworks — Yao Huang offers a grounded, urgent, and actionable perspective.

    It’s not about hope. It’s about execution.

    Rice scientist receives $2 million award for research on 'new type of fuel'

    winner, winner

    Rice University chemistry professor László Kürti was named as a recipient of the 2025 Ross M. Brown Investigator Award from the California Institute of Technology’s Brown Institute for Basic Sciences.

    Kürti is one of eight mid-career faculty members to receive up to $2 million over five years for their research in the physical sciences.

    “I’m greatly honored,” Kürti said in a news release. “We will learn a tremendous amount in the next five years and gain a much clearer understanding of the challenges ahead.”

    Kürti was selected for the research he’s been developing for six years on a molecule called tetrahedral N4, which studies show can release large amounts of energy on demand. The molecule can also decompose directly into nitrogen gas without producing carbon dioxide or water vapor. Kürti believes N4 can be used as a "new type of fuel for vehicles."

    “Eventually, N4 and other stable, neutral polynitrogen cages could be used to power rockets, helping us reach the moon or Mars faster and with heavier payloads,” he added in this release.

    The Brown Investigator Awards were founded by entrepreneur and Caltech alumnus Ross M. Brown and established by the Brown Science Foundation in 2020. The organization has recognized 21 scientists over the last five years.

    “Midcareer faculty are at a time in their careers when they are poised and prepared to make profound contributions to their fields,” Brown said in the news release. “My continuing hope is that the resources provided by the Brown Investigator Awards will allow them to pursue riskier innovative ideas that extend beyond their existing research efforts and align with new or developing passions, especially during this time of funding uncertainty.”
