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.

Houston's top energy transition founders explain their biggest challenges

overheard

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 InnoVentRenewables, 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 SageGeosystems, 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)."

The Digital Wildcatters have created a platform for individuals to get their questions answered by experts and a space for companies seeking qualified talent. Collide is structured to ignite the next generation of energy innovators, as Collin McLelland, co-founder and CEO of Digital Wildcatters, tells EnergyCapital.

“If you look at what we’ve done historically with Digital Wildcatters, we’ve built an extremely engaged community of energy professionals — it’s a next generation community, very young forward thinking professionals that are working towards solving the world’s energy crisis,” McLelland says.

The roll out of Collide has been intentionally gradual, McLelland says because they want to shape the user experience based on feedback from ongoing focus groups. Currently they have about 1,000 users and are examining how they can make the app valuable to them before providing the platform to a wider audience.

McLelland says there are two major issues within the energy sector that Collide hopes to address — a lack of knowledge about energy verticals and difficulty recruiting talent.

“What we really see with our platform is being able to bring people together where if you want to find a piece of information, you need to find a subject matter expert, or if you want to find your next job, it happens on the Collide platform,” McLelland says. Read the full story.

Why this Houston energy innovator created a spin-off company to focus on tire waste

Q&A

With over a billion cars currently on the road — each with four tires that will eventually end up discarded, one Houstonian is hoping to create the infrastructure to sustainably dispose of tire waste now and into the future.

Announced earlier this month, Vibhu Sharma founded InnoVent Renewables to establish production facilities that utilize a proprietary continuous pyrolysis technology that is able to convert waste tires, plastics, and biomass into fuels and chemicals.

In a Q&A with EnergyCapital, Sharma explains his plans to sustainably impact the tire waste space and his vision for his company.

EnergyCapital: Why did you decide to expand the InnoVent brand to focus on renewable energy?

Vibhu Sharma: InnoVent Technology has been developing and implementing projects in renewable energy, chemicals, and oil and gas. Project examples include an EV battery chemical project for a $9 billion chemical company, municipal solid waste (MSW) to biogas, and of course pyrolysis of waste tires, plastics and biomass. Renewable energy is the calling of our time, and with our expertise in this area, we felt strongly that we must do more. With 1 billion waste tires disposed of every year, we wanted to focus on this vast opportunity, which led us to create a spin-off company called InnoVent Renewables, in order to specifically focus on innovative technologies such as pyrolysis of waste tires. We received overwhelming response from our investors and partners, and we're on our way to the first commercial production facility.

EC: Can you describe the process of converting the materials into fuel? How does it work?

VS: At a high level the process involves shredding of tires into small cubes, which are then fed into the main pyrolysis reactor. They're pre-heated enroute to the reactor, using the pyrolysis gas that's generated in the reactor. The reactor operates at a high temperature, and in the absence of oxygen, and decomposes the tires into various components. These are then separated using various techniques. The gases are treated to remove any sulfur, and then used to preheat the shredded tires. The pyrolysis oil (pyoil), which is one of the main products, is condensed out.

The pyoil is further processed to separate out higher value aromatics, and the remaining pyoil is equivalent to off-road diesel or fuel oil, and can be sold directly. The aromatic stream can be further processed or sold directly. It makes a great feed for petrochemical plants, or carbon black plants.

There are two solid products as well. These are recovered carbon black (rCB) and steel wire. Steel wire is separated from the rCB mix and can be sold directly. The rCB is further processed through a series of steps resulting in a high-quality powder which can be used to make tires, making it a completely circular product.

EC: Tell me about your expansion plan. Where are you hoping to grow the company and why in those particular regions?

VS: Our immediate plan is to build and start our commercial production facility in Monterrey, Mexico. Monterrey happens to be home to nearly 50 million waste tires. We are located very close to where the source is. We will set up our initial production train there, and leave room to expand to multiple parallel trains at the same site or nearby sites.

We have our own engineering and operations team in Monterrey, and we have access to modern infrastructure and resources, as this is a fast-growing city of 6 million people. In addition, we have close proximity to Texas for product distribution. Our next step will be to establish production facilities in Texas. We are based in Texas. Texas also has access to at least 50 million tires in landfills all across the state, and the state is taking significant measures to address this issue. We are already engaging with various entities here to plan our expansion site. Meanwhile we have been receiving high levels of interest from counties in Florida, California, as well as international sites in India and the Middle East to set up production facilities there. There are one billion waste tires disposed of every year, it's a huge opportunity. Some of these expansion decisions will depend on support from state governments, access to tires, cost of setting up the facility, etc.

EC: Do you plan on raising investment funding to reach these goals? If not, how will you be funded?

VS: We are fully funded for our first production site in Mexico. Based on our cash flow projections, we should be able to self-fund expansions at that site, and eventually add additional production trains. In order to accelerate our expansion at other sites, we intend to raise funds, with support from different states/counties in the USA where we decide to expand, and with support from investors. We are also open to strategic partners that can team up with us for the expansion both internationally and domestically.

EC:  In the long term, what's the impact you hope to make?

VS: Each production train of 15,000 tons that recycles 1 million passenger tires per year, can reduce CO2 emissions by 80 million pounds per year. Over the next five years, our goal is to get that target to 150,000 tons of recycling, which is 800 million pounds of CO2 emission reduction. That's a good impact to have, and a great way to drive renewable energy forward.

Texas falls lower on national ranking of greenest states for 2025

room to improve

Texas dropped in the rankings on WalletHub's Greenest States 2025 report.

The report, released last month, considered 28 relevant metrics—from air and water quality to the number of alternative fuel stations and green buildings per capita—to call out states doing the best (and worst) jobs of caring for the environment.

Texas came in at No. 42 out of 50, with a total score of 42.54 out of 100. Last year, the Lone Star State ranked No. 38 with a score of 50.40 based on 25 metrics.

Texas' poor ranking was driven by its last-placed ranking, coming in at No. 50, for overall environmental quality. It was tied for No. 45 for air quality and ranked No. 46 for water quality, which helped comprise the overall environmental quality score.

Other metrics fell closer toward the middle of the pack. The state ranked No. 32 for eco-friendly behaviors and No. 39 for climate-change contributions.

California also fell on the annual report. While the state claimed the top spot in 2024, it came in at No. 7 this year. Vermont, which came in second in 2024, was named the greenest state in 2025.

Hawaii, which didn't crack the top five last year, was ranked No. 2 on the 2025 report. New York, Maryland and Maine rounded out the top five this year.

West Virginia was the country's least green state again this year, followed by Louisiana, Kentucky, Alabama and Mississippi.

The report also showed that Democrat-led states ranked around No. 12 on average, whereas Republican states fell at around No. 33.

While the WalletHub report seems bleak for Texas, others have shown more positive signs for the state. Texas was ranked slightly above average in a recent ranking of the best states for sustainable development. A recently released U.S. Energy Storage Monitor shows that Texas led all states and surpassed California in the fourth quarter of 2024 by installing 1.2 gigawatts of utility-scale energy storage for solar and wind power.

Still, WalletHub also recently ranked Houston No. 98 out of 100 of the largest cities on its Greenest Cities in America report. Read more here.

Houston renewables developer and Google agree to second solar collaboration

power purchase

EnergyRe, a developer of large-scale renewable energy projects with headquarters in Houston and New York, has signed a renewable energy agreement that will allow Google to invest in and purchase renewable energy credits (RECs) from its projects under development in South Carolina.

Google will be able to pull from energyRe’s portfolio of more than 600 megawatts of new solar and solar storage projects in the state.

The agreement marks the second partnership between the companies. Last year, energyRe and Google signed a 12-year power purchase agreement in which Google would purchase renewable energy from a 435-megawatt solar project. EnergyRe would supply electricity and RECs generated from the solar project to Google to power the equivalent of more than 56,000 homes.

"Strengthening the grid by deploying more reliable and clean energy is crucial for supporting the digital infrastructure that businesses and individuals depend on," Amanda Peterson Corio, head of data center energy at Google, said in a news release. "Our collaboration with energyRe will help power our data centers and the broader economic growth of South Carolina."

EnergyRe's work includes developing high-voltage transmission, onshore and offshore wind, large-scale solar, distributed generation and storage assets in markets around the United States. Its national onshore utility-scale portfolio includes 1,520 megawatts of contracted solar assets and 398 megawatt-hours of contracted battery storage assets.

"This agreement is a milestone in energyRe's mission to develop innovative and impactful clean energy solutions for the future," Miguel Prado, CEO of energyRe, added in the news release."We're honored to partner with Google to help advance their ambitious sustainability and decarbonization objectives while delivering dependable, locally sourced clean energy to meet growing energy demands."

Google aims to achieve net-zero carbon emissions across its operations and value chain by 2030.
