Houston has become the hub for startups and companies looking to scale innovative technologies that are transforming the energy industry and advancing a sustainable, low-carbon future. Last month, the inaugural Houston Energy and Climate Startup Week 2024 successfully highlighted this mission.

Rice Alliance for Technology and Entrepreneurship, Halliburton Labs, Greentown Labs, Digital Wildcatters launched the inaugural startup week in collaboration with the Partnership’s Houston Energy Transition Initiative. The week brought together leading energy and climate venture capital investors, industry leaders, and startups from around the world.

Over 30 events took place from September 9-13, featuring more than 100 speakers and 125 startups. Attendance numbers came in at over 1,400 people across the week’s anchor events, and additional events were individually organized by organizations and startups in Houston’s ecosystem.

“By hosting the Houston Energy & Climate Startup Week, we're not just showcasing our city's strengths - we're actively shaping its future. This event is a critical catalyst for fostering collaboration, investment and talent development within the burgeoning energy and climate tech ecosystem. This week is about demonstrating our commitment to that future and inspiring the next generation of energy innovators,” says Janice Tran, Kanin Energy CEO & Co-Founder

The Kickoff event, sponsored by Repsol, Microsoft and BBVA, hosted fireside chats by several of Houston’s leading startups, including Solugen, Cemvita, Kanin Energy and Syzygy.

“Houston is at the forefront of not just energy innovation, but industrial innovation more broadly. With the momentum that's built over the last few years, it's the perfect time to showcase our progress and drive further advancements in climate solutions,” says Gaurab Chakrabarti, Solugen CEO and co-founder.

Houston is home to more than 65 incubators and accelerators and over 260 cleantech and climate tech startups. The region continues to build momentum and is focused on attracting investment for this growing sector, seeing a 577 percent growth since 2019. According to Partnership data, there has been over $1.95 billion and 175 deals with cleantech and climate tech startups.

"Houston is uniquely positioned to tackle the greatest challenge of our time - producing more energy with fewer emissions. This city is where energy innovation scales and opportunity thrives. As a natural hub for startups and investors, Houston brought this to life during Houston Energy and Climate Startup Week. Years in the making, this event was launched to answer the question: Can the whole be greater than the sum of its parts? This past week proved it can. We look forward to continue building on this successful week,” says Jane Stricker, senior vice president at Greater Houston Partnership and executive director of the Houston Energy Transition Initiative.

Houston cleantech co. secures Canadian recognition as a top investible startup

made the cut

A Canadian organization has called out the top 50 most investible energy transition companies in the country, and one Canada-founded, Houston-based startup made the cut.

The 2023 Foresight 50, Foresight Canada's 50 Most Investible Cleantech Ventures, sought to highlight the top companies moving the needle toward Net Zero. Kanin Energy — founded by CEO Janice Tran in Calgary in 2020 but relocated to Houston by way of Greentown Labs — developed a waste-heat-to-power concept for generating clean energy.

“The ventures included in this year’s Foresight 50 are nothing short of awe-inspiring. These game-changing innovators are scaling the critical climate solutions we need to solve the world’s most urgent climate challenges and accelerate the transition to net zero. Congratulations and thank you for all you are doing for Canadian cleantech," says Jeanette Jackson, CEO of Foresight Canada, in a news release.

According to the organization, 41 cleantech investors evaluated detailed profiles the companies submitted. They looked at investibility, potential environmental and employment impact, leadership and team, and probability of success, according to Foresight Canada.

"Canada has no shortage of inspiring innovators with the potential to solve global climate challenges. But these companies struggle to attract the long-term capital and recognition needed to make their businesses competitive on a global scale," Kanin Energy's team writes in its news release.

A year ago, the Kanin team visited Houston to see if the city could be a fit for an office. In July of 2022, Tran opened Kanin Energy offices in Greentown Labs.

“We’re hiring and building our team office out of Greentown. It’s been really great for us,” she previously told EnergyCapital.

Earlier this month, Kanin Energy was named a finalist in the 2023 Houston Innovation Awards.

4 biggest challenges of Houston-based sustainability startups

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 EnergyCapital's sister site, 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.

    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

    Rice Alliance calls for participants for its annual energy conference

    now's the time to apply

    This year marks the 20th anniversary of Energy Tech Venture Day, a one-day symposium for energy innovation put on by the Rice Alliance for Technology and Entrepreneurship. The organization is currently calling for applications for startups interested in participating.

    The event is taking place on September 21 at Rice University and will bring together energy innovators, investors, corporate leaders, and the rest of the energy ecosystem. The programming will include panels and discussions as well as startup pitches from the Rice Alliance's Clean Energy Accelerator 2023 cohort.

    In addition to the CEA pitches, energy tech startups from around the world can apply to be a part of the day and be in the running to be recognized as a select group as the "most-promising" at the conclusion of the pitches. Applications can be filled out online and are due July 14. Registration is also open online.

    According to Rice, 90 or so companies will be selected to participate in one-on-one meetings with around 75 investors. The organization conducts a unique matchmaking round that pairs up investors and founders for four to 10 of these office hour meetings which will take place the day before the main event.

    On the day of the Energy Tech Venture Day, around 40 companies will pitch to the rest of the crowd. At the end of the day and based off the investor feedback from the one-on-one meetings, 10 energy tech startups will be deemed the most-promising businesses and be presented with awards.

    Last year, over a third of the companies that pitched were based in the Houston area. Two Houston-based companies received awards at the end of the day, including:

    • Kanin Energy, which works with heavy Industry to turn their waste heat into a clean baseload power source. The platform also provides tools such as project development, financing, and operations.
    • Syzygy Plasmonics, which is commercializing its light-reacting energy, which would greatly reduce carbon emissions in the chemical industry. The technology originated out of Rice University.

    This energy transition startup taps Houston to grow, build its waste-heat-to-power tech

    eyes on hou

    Waste heat is everywhere, but in Houston, the Energy Capital of the World, it is becoming a hot commodity. What is it? Janice Tran, CEO of Kanin Energy, uses the example of turning ore into steel.

    “There’s a lot of heat involved in that chemical process,” she says. “It’s a waste of energy.”

    But Kanin Energy can do something about that. Its waste-heat-to-power, or WHP, concept uses a technology called organic rankine cycle. Tran explains that heat drives a turbine that generates electricity.

    “It’s a very similar concept to a steam engine,” she says. Tran adds that the best term for what Kanin Energy does is “waste heat recovery.”

    Emission-free power should be its own virtuous goal, but for companies creating waste heat, it can be an expensive endeavor both in terms of capital and human resources to work on energy transition solutions. But Kanin Energy helps companies to decarbonize with no cost to them.

    “We can pay for the projects, then we pay the customers for that heat. We turn a waste product into a revenue stream for our customer,” Tran explains. Kanin Energy then sells the clean power back to the facility or to the grid, hence decarbonizing the facility gratis. Financing, construction, and operations are all part of the package.

    Kanin Energy began at the height of the COVID-19 pandemic, in the spring of 2020.

    “We started like a lotus. A lotus grows in mud — you start in the worst conditions and everything is better and easier from there,” says Tran.

    That tough birth has helped provide the team with a discipline and thoughtfulness that’s been key to the company’s culture. Remote work has forced the team to get procedures clearly in place and react efficiently.

    Back in May of 2020, its inception took place in Calgary. But the team, which also includes CDO Dan Fipke and CTO Jake Bainbridge, began to notice that many of their customers were either based in Houston or had Houston ties.

    A year ago, the Kanin team visited Houston to see if the city could be a fit for an office. In July of 2022, Tran opened Kanin Energy offices in Greentown Labs.

    “We’re hiring and building our team office out of Greentown. It’s been really great for us,” she says.

    With the company now in its commercialization stage, Tran says that becoming part of the Houston energy ecosystem has been invaluable for Kanin.

    The investments being made in climate tech and in energy transition make Space City the right place for the company. For Canadian-born Kanin Energy, Houston is now home. Investors across the nation, including Texas, are now helping Kanin to blossom, much like the lotus.

    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)
    5. Fervo Energy (Houston)
    6. Plus One Robotics (San Antonio)
    7. Diligent Robotics (Austin)
    8. HighRadius (Houston)
    9. LTK (Dallas)
    10. Eagle Eye Networks (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.
