Vibhu Sharma observed a huge sustainability problem within the automotive industry, and he was tired of no one doing anything about it.
"Globally, humans dispose 1 billion tires every year," Sharma says on the Houston Innovators Podcast. "It's a massive environmental and public health problem because these tires can take hundreds of years to break down, and what they start doing is leaking chemicals into the soil."
Today, 98 percent of all tires end up in landfills, Sharma says, and this waste contributes to a multitude of problems — from mosquito and pest infestation to chemical leaks and fire hazards. That's why he founded InnoVent Renewables, a Houston-based company that uses its proprietary continuous pyrolysis technology to convert waste tires into valuable fuels, steel, and chemicals.
While the process of pyrolysis — decomposing materials using high heat — isn't new, InnoVent's process has a potential to be uniquely impactful. As Sharma explains on the show, he's targeting areas with an existing supply of waste tires. The company's first plant — located in Monterrey, Mexico — is expected to go online early in the new year, an impressive accomplishment considering Sharma started his company just over a year ago and bootstrapped the business with only a friends and family round of funding.
"It's about 16 months or so from start to commercial operations, which is phenomenal when you consider what it takes to build and operate a chemical or petrochemical facility," Sharma says.
Currently, with the facility close to operations, Sharma is looking to secure customers for the plant's products — which includes diesel, steel, and carbon black — and he doesn't have to look too far out of the automotive industry for his potential customer base. Additionally, the plant should be net zero by day one, since Sharma says he will be using the output to fuel operations.
While the first facility is in Mexico, Sharma says they are already looking at potential secondary locations with Texas at the top of his list. Houston, where Sharma has worked for 26 years, has been a strategic headquarters for InnoVent.
"When it came to doing the research and development, we were able to work with experts in the Houston and Texas areas to test out our idea and validate it," Sharma says. "One thing that gets under appreciated about Houston is how well it's connected to the rest of the world. There are so many direct connections between Houston and Latin America, as well as Europe, Middle East, and Asia."
"I also find that the Houston ecosystem is very supportive of new companies and helping them grow," he adds.

Twenty promising climatetech companies were selected to advance to the final stage of a global competition backed by Elon Musk's foundation — and three of the finalists hail from Houston.
Vaulted Deep, Mati Carbon, and Climate Robotics secured finalists spots in XPRIZE's four-year global competition is designed to combat climate change with innovative solutions. XPRIZE Carbon Removal will offer $100 million to innovators who are creating solutions that removes carbon dioxide directly from the atmosphere or the oceans, and then sequester it sustainably.
"For the world to effectively address greenhouse gas emissions, carbon removal is an essential element of the path to Net Zero. There's no way to reverse humanity's impact on the climate without extracting carbon from our atmosphere and oceans," Anousheh Ansari, CEO of XPRIZE, says in a news release. "We need a range of bold, innovative CDR solutions to manage the vast quantities of CO2 released into our environment and impacting our planet.
"The teams that have been competing for this Prize are all part of building a set of robust and effective solutions and our 20 teams advancing to the final stage of XPRIZE Carbon Removal will have an opportunity to demonstrate their potential to have a significant impact on the climate," Ansari continues.
The finalists — categorized into four sections: air, rocks, oceans, and land — were selected based upon their performance in three key areas: operations, sustainability, and cost. The full list of 20 finalists is available online.
Around 20 Houston-area companies were initially identified by the challenge. Here's a look at the three that are advancing to the finals:
Mati, in the Rocks category, durably removes carbon from the atmosphere using basalt based enhanced rock weathering (ERW) in smallholder rice paddy farms. This process, which is being demonstrated in India, removes atmospheric CO2 while adding key nutrients in the soil helping to restore degraded soils to benefit smallholder farmers.
Climate Robotics, in the Land category, enables broad-scale agriculture adoption of biochar which builds soil health and removes excess carbon from the atmosphere. The company's mobile technology converts crop residues into durable biochar on the fly and in the field, making the economics work for farmers and our ecosystems.
Vaulted Deep, also in the Land category, delivers scalable, permanent, carbon removal by geologically sequestering carbon-filled organic wastes. Their patented slurry sequestration, which involves the geological injection of minimally processed wastes for permanent (10,000+ year) carbon removal.
"This cohort of exceptional teams represents a diversity of innovations and solutions across a range of CDR pathways, and shows the significant progress the industry is making in a short period of time," Nikki Batchelor, executive director of XPRIZE Carbon Removal, says in the release. "Over the past three years, this competition has helped accelerate the pace of technology development for a whole new industry of high-potential solutions aimed at reversing climate change."
It's the first time the company has used EVs in any of its upstream sites, including the Permian Basin. Photo via exxonmobil.com
ExxonMobil has upgraded its Permian Basin fleet of trucks with sustainability in mind.
The Houston-headquartered company announced a new pilot program last week, rolling out 10 new all-electric pickup trucks at its Cowboy Central Delivery Point in southeast New Mexico. It's the first time the company has used EVs in any of its upstream sites, including the Permian Basin.
“We expect these EV trucks will require less maintenance, which will help reduce cost, while also contributing to our plan to achieve net zero Scope 1 and 2 emissions in our Permian operations by 2030," Kartik Garg, ExxonMobil's New Mexico production manager, says in a news release.
ExxonMobil has already deployed EV trucks at its facilities in Baytown, Beaumont, and Baton Rouge, but the Permian Basin, which accounts for about half of ExxonMobil's total U.S. oil production, is a larger site. The company reports that "a typical vehicle there can log 30,000 miles a year."
At the end of last year, ExxonMobil increased its financial commitment to implementing more sustainable solutions. The company reported that it is pursuing more than $20 billion of lower-emissions opportunities through 2027.

The Women in Energy Global Study is an annual guide that delivers insights on how to retain female talent in a challenging world. It’s a critical roadmap for business leaders, managers, recruiters, and diversity and inclusion professionals to what women want, need, and can offer in the global energy workplace.
The report dives into the data to reveal the nature and aspirations of the female energy workforce. It explores the kids of jobs women are doing and the level of seniority that they are reaching, the career issues they face, what motivates them to contribute their skills to the energy transition and what they need to truly thrive.
The energy transition was a strong thread running through this year’s global survey with a commitment to Net Zero being the stand-out factor that attracts women to a company. Respondents came from an even greater variety of sectors and roles both within and outside the energy industry, reflecting the growing richness and complexity of energy today and the exciting new opportunities it offers.
This year's results showed that oil and gas is the largest employer of women, followed by renewables, and most respondents have reached middle-management level in their career. However, there are still more women than men at the bottom and more men at the top. Women are more likely to be in project management, while men are more likely to be in engineering, and only 6 percent of field services roles are held by women.
Work-life interface and flexibility
Employers appear to be rolling back some of the flexible working policies introduced during the COVID-19 pandemic yet offering options for where and when work is an important value proposition for any company wanting to attract and retain talent.
The good news is that most men and women feel they now have a good work life balance, a positive shift from last year when most said they didn't. Women said that better flexible working would make the most difference to work-life balance.
Attracting and developing diverse talent and helping women thrive
Companies’ commitment to DEI appears to be declining, a reversal in trend from previous years. If this is more than just lack of visibility of what has become "business as usual," then organizations need to remember that better DEI leads to better business performance and it is critical to communicate efforts in this area.
Key things women want from their employer are better professional development, sponsorship and mentoring, flexible working and the opportunity for job-share or part-time working, but there appears to be delivery gap between availability of policies and their uptake.
The demand for good paternity leave is huge among men – more than half said they wanted to see it introduced or improved – and this could be a gamechanger for both sexes. Additionally, a strong commitment to net zero still makes a company more attractive to both women and men. Other key factors for women when choosing their employer are an inclusive workplace culture, benefits and a commitment to DEI.
Time to pave the way
When we amplify the voices of women in the global energy market, we not only bring attention to the challenges they face but also highlight the vast potential they hold. By understanding the barriers they encounter, leaders, managers, and recruiters can implement targeted strategies to create more inclusive and diverse work environments. This not only benefits women in the industry but also fosters innovation and drives growth in our ever-evolving energy sector. As we pave the way for more opportunities and empowerment for women in energy, we are shaping a brighter and more sustainable future for all.

A Houston tech company is building a next-generation supercomputer for one of the world’s largest energy providers.
Hewlett Packard Enterprise announced its plans to build HPC6 for Italian energy company Eni. Eni will use the system to advance scientific discovery and engineering toward accelerating innovation in energy transition to help aid its goal in getting to net zero. HPC6 is expected to be one of the world’s most powerful supercomputers owned by an enterprise.
HPC6 will be built with the same innovations that power the world’s fastest supercomputer to support data and image-intensive workloads across artificial intelligence, modeling, and simulation. According to a news release from HPE, the system will “augment Eni’s existing research that is focused on studying and identifying new energy sources, including renewable energy.”
Eni’s HPC6 will be installed in the company’s energy Green Data Center in Italy. The center will be upgraded to support HPE’s direct liquid-cooling (DLC) capabilities.
"Businesses are finding themselves balancing the huge business opportunities enabled by their AI investments with the responsibility of mitigating the environmental impact of these powerful systems," Antonio Neri, president and CEO of HPE, says in a news release.
"As the leader in developing energy efficient AI and supercomputing solutions, HPE is uniquely positioned to help organizations minimize power consumption while maximizing business outcomes," he continues. "We are excited to play a role in Eni’s commitment to decarbonization supported by digitalization and innovation."
Originally announced in 2020, HPE moved its headquarters to Houston in 2022.
Scott Nyquist on what the path to net-zero will look like. Graphic via mckinsey.com
The $275 trillion question: What does the road to net-zero look like?
That’s a good question, and McKinsey took a serious stab at providing an answer in a 2022 report, it considers the net-zero scenario described by the Network for Greening the Financial System (NGFS), a consortium of 105 central banks and financial institutions. McKinsey then describes the costs, benefits, and social and economic changes that would likely be required for the world to start, stay on, and finish the pathway described by the NGFS.
Here is what the report isn’t, and what it doesn’t do. It isn’t a roadmap to net zero, and it does not make predictions. Rather, it offers estimates related to one specific scenario. It does not say who should pay. It does not address adaptation. It doesn’t even assume that restricting global temperature rises to 1.5 degrees Celsius by 2050 is achievable. It doesn’t assert that this is the best or only way to of. Indeed, it notes that “it is likely that real outcomes will diverge from these estimates.”
What the report does do is more interesting: with rigor and thoughtfulness, it thinks through what a genuine, global effort to get to net zero would take. Here are a few insights from the report I found particularly noteworthy.
It won’t come cheap. Capital spending by 2050 under the NGFS scenario would add up to $275 trillion, or $9.2 trillion per year on average. That is about $3.5 trillion a year more than is being spent today, or the equivalent of about half of global corporate profits in 2020. In addition, about $1 trillion of current spending would need to shift from high- to low-emissions assets. In short, it’s a lot of money. Of course, some of these costs are also investments that will deliver returns, and indeed the share that do so will probably rise over the decades. Upfront spending now could also reduce operating costs down the line, through greater efficiency and lower maintenance costs. And it’s important to keep in mind the considerable benefit of a healthier planet and a stable climate, with cleaner air and richer land. But the authors do not shy away from the larger point: “Reaching net-zero emissions will thus require a transformation of the global economy.”
Some countries are going to be hit harder than others. It’s hardly surprising to read that countries like Saudi Arabia, Russia, and Venezuela, which rely heavily on oil and gas resources, are going to have a more difficult time adjusting. The same is true for many developing economies. To some extent their residents can leapfrog to cleaner, greener technologies, just as they skipped the landline in favor of cellphones. But other factors weigh in. For example, developing countries are more likely to have high-emissions manufacturing as a major share of the economy; services are generally lower emission. In addition, poorer countries still have to build much of their infrastructure, which is costly. All this adds up. The report estimates that India and sub-Saharan Africa would need to spend almost 11 percent of its GDP on physical assets related to energy and land to get to net zero; in other Asian countries and Latin America, it is more than 9 percent. For Europe and the United States, by contrast, the figure is about 6 percent.
Now is better than later. An orderly, gradual transition would likely be both gentler and cheaper than a hasty, disorderly one. The report sees spending as “frontloaded,” meaning that there is more of it in the next decade to 15 years, and then it declines. That is because of the need for substantial capital investment. But why does this matter? There is timing, for one thing. If low emissions sources do not increase as fast (or preferably faster) than high-emissions ones are retired, there will be shortages or price rises. Both would be unpleasant, and could also cut into public support for change. And then there is the matter of money. If a coal plant is built today—as many are—and then has to be shut down, abruptly and well before its useful life over, a lot of money that was invested in it will never be recouped. The report estimates that as much as $2.1 trillion assets in the power sector alone could be stranded by 2050. Many of these assets are capitalized on the balance sheets of listed companies; shutting them down prematurely could bring bankruptcies and credit defaults, and that could affect the global financial system.
The world would look very different. Under the NGFS scenario, oil and gas production volumes in 2050 would be 55 percent and 70 percent lower, respectively, and coal would just about vanish. The market share for battery or fuel cell-electric vehicles would be close to 100 percent. Many existing jobs would disappear, and because these assets tend to be geographically concentrated, the effects on local communities would be harsh. For example, more than 10 percent of jobs in 44 US counties are in the coal, oil and gas, fossil fuel power, and automotive sectors. On the whole, McKinsey estimates that the transition could mean the loss of 187 million jobs—but the creation of 202 million new ones. Reaching net zero would also make demands on individuals, such as switching to electric vehicles, making their homes more energy efficient, and eating less meat like beef and lamb (cows and sheep are ruminants, emitting methane, a greenhouse gas).
There’s a lot else worth thinking about in the report, which goes into some detail about forestry and agriculture, for example, as well as the role of climate finance and what can be done to fill technology gaps. And its closing sentence is worth pondering: “The key issue is whether the world can muster the requisite boldness and resolve to broaden its response during the next decade or so, which will in all likelihood decide the nature of the transition.”
So, is something like this going to happen? I don’t know. There is certainly momentum. As of January 27, 2022, 136 countries accounting for almost 90 percent of both emissions and GDP, have signed up to the idea. But these pledges are not cast in stone, or indeed in legislation, in many places, and as a rule policy is running far short of the promise. “Moving to action,” the report notes dryly, “has not proven easy or straightforward.”
And while some things can be done from the top down, others cannot—such as the considerable shift in human diets away from high-emissions (and delicious) beef and lamb and more toward poultry and legumes. Moreover, inertia and vested interests are powerful forces. “Government and business would need to act together with singular unity, resolve, and ingenuity, and extend their planning and investment horizons even as they take immediate actions to manage risks and capture opportunities,” the report concludes. That’s a big ask.
So, like McKinsey, I am not going to make predictions. But for an analysis of what it would take, this is a valuable effort.
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.
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.
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:
The people in power don’t actually have this figured out, and
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 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.”
