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.

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.

New Houston company launches to turn recycled materials into fuel

renewables

Every year, over a billion tires are disposed of globally, and, while in use, tires are used to reach maximum speed on the road, their decomposition times are inordinately slow.

Houston-based InnoVent Renewables has a solution. The company launched this week to drive renewable energy forward with its proprietary continuous pyrolysis technology that is able to convert waste tires, plastics, and biomass into fuels and chemicals.

“We are thrilled to formally launch InnoVent Renewables and plan to ramp-up operations into early 2024," InnoVent Renewables CEO Vibhu Sharma says in a news release. “Our investors, strategic advisors, and management team are all fully committed to our success as we address the global challenge of waste tires. We firmly believe our proven process, deployed at scale globally, will have a huge positive impact on our climate and fill a clear environment need.”

While InnoVent Renewables has only just launched, Sharma has worked in the space for years with his company InnoVent Technology, a technology and consulting company working with clients on turnkey process technology and asset management solutions within the process and manufacturing industries.

During InnoVent's unique material breakdown process, its pyrolysis technology recovers chemicals from the products, and produces high-quality fuels — in in a net-zero capacity. The company's products include renewable pyrolysis oil, or PyOil; aromatics; recovered carbon black, or rCB; and steel wire. PyOil, according to InnoVent's website, can be sold as fuel oil, off-road diesel, or used as a feedstock to crude blending.

"The InnoVent team conducted product quality analysis in conjunction with a world renowned research facility and results were further validated and scaled up in 2022, using comprehensive process simulation software and pre-engineering design work for scale-up," reads the InnoVent website.

Headquartered in Houston, the company has operations in Pune, India, and Monterrey, Mexico, with plans for aggressive growth across North America and Latin America. Specifically, InnoVent is planning to open a commercial production plant in Monterrey next year. Down the road, the company's team hopes to expand in Europe, the Middle East, and Asia-Pacific.

Rice research team's study keeps CO2-to-fuel devices running 50 times longer

new findings

In a new study published in the journal Science, a team of Rice University researchers shared findings on how acid bubbles can improve the stability of electrochemical devices that convert carbon dioxide into useful fuels and chemicals.

The team led by Rice associate professor Hoatian Wang addressed an issue in the performance and stability of CO2 reduction systems. The gas flow channels in the systems often clog due to salt buildup, reducing efficiency and causing the devices to fail prematurely after about 80 hours of operation.

“Salt precipitation blocks CO2 transport and floods the gas diffusion electrode, which leads to performance failure,” Wang said in a news release. “This typically happens within a few hundred hours, which is far from commercial viability.”

By using an acid-humidified CO2 technique, the team was able to extend the operational life of a CO2 reduction system more than 50-fold, demonstrating more than 4,500 hours of stable operation in a scaled-up reactor.

The Rice team made a simple swap with a significant impact. Instead of using water to humidify the CO2 gas input into the reactor, the team bubbled the gas through an acid solution such as hydrochloric, formic or acetic acid. This process made more soluble salt formations that did not crystallize or block the channels.

The process has major implications for an emerging green technology known as electrochemical CO2 reduction, or CO2RR, that transforms climate-warming CO2 into products like carbon monoxide, ethylene, or alcohols. The products can be further refined into fuels or feedstocks.

“Using the traditional method of water-humidified CO2 could lead to salt formation in the cathode gas flow channels,” Shaoyun Hao, postdoctoral research associate in chemical and biomolecular engineering at Rice and co-first author, explained in the news release. “We hypothesized — and confirmed — that acid vapor could dissolve the salt and convert the low solubility KHCO3 into salt with higher solubility, thus shifting the solubility balance just enough to avoid clogging without affecting catalyst performance.”

The Rice team believes the work can lead to more scalable CO2 electrolyzers, which is vital if the technology is to be deployed at industrial scales as part of carbon capture and utilization strategies. Since the approach itself is relatively simple, it could lead to a more cost-effective and efficient solution. It also worked well with multiple catalyst types, including zinc oxide, copper oxide and bismuth oxide, which are allo used to target different CO2RR products.

“Our method addresses a long-standing obstacle with a low-cost, easily implementable solution,” Ahmad Elgazzar, co-first author and graduate student in chemical and biomolecular engineering at Rice, added in the release. “It’s a step toward making carbon utilization technologies more commercially viable and more sustainable.”

A team led by Wang and in collaboration with researchers from the University of Houston also shared findings on salt precipitation buildup and CO2RR in a recent edition of the journal Nature Energy. Read more here.

The case for smarter CUI inspections in the energy sector

Guest Column

Corrosion under insulation (CUI) accounts for roughly 60% of pipeline leaks in the U.S. oil and gas sector. Yet many operators still rely on outdated inspection methods that are slow, risky, and economically unsustainable.

This year, widespread budget cuts and layoffs across the sector are forcing refineries to do more with less. Efficiency is no longer a goal; it’s a mandate. The challenge: how to maintain safety and reliability without overextending resources?

Fortunately, a new generation of technologies is gaining traction in the oil and gas industry, offering operators faster, safer, and more cost-effective ways to identify and mitigate CUI.

Hidden cost of corrosion

Corrosion is a pervasive threat, with CUI posing the greatest risk to refinery operations. Insulation conceals damage until it becomes severe, making detection difficult and ultimately leading to failure. NACE International estimates the annual cost of corrosion in the U.S. at $276 billion.

Compounding the issue is aging infrastructure: roughly half of the nation’s 2.6 million miles of pipeline are over 50 years old. Aging infrastructure increases the urgency and the cost of inspections.

So, the question is: Are we at a breaking point or an inflection point? The answer depends largely on how quickly the industry can move beyond inspection methods that no longer match today's operational or economic realities.

Legacy methods such as insulation stripping, scaffolding, and manual NDT are slow, hazardous, and offer incomplete coverage. With maintenance budgets tightening, these methods are no longer viable.

Why traditional inspection falls short

Without question, what worked 50 years ago no longer works today. Traditional inspection methods are slow, siloed, and dangerously incomplete.

Insulation removal:

  • Disruptive and expensive.
  • Labor-intensive and time-consuming, with a high risk of process upsets and insulation damage.
  • Limited coverage. Often targets a small percentage of piping, leaving large areas unchecked.
  • Health risks: Exposes workers to hazardous materials such as asbestos or fiberglass.

Rope access and scaffolding:

  • Safety hazards. Falls from height remain a leading cause of injury.
  • Restricted time and access. Weather, fatigue, and complex layouts limit coverage and effectiveness.
  • High coordination costs. Multiple contractors, complex scheduling, and oversight, which require continuous monitoring, documentation, and compliance assurance across vendors and protocols drive up costs.

Spot checks:

  • Low detection probability. Random sampling often fails to detect localized corrosion.
  • Data gaps. Paper records and inconsistent methods hinder lifecycle asset planning.
  • Reactive, not proactive: Problems are often discovered late after damage has already occurred.

A smarter way forward

While traditional NDT methods for CUI like Pulsed Eddy Current (PEC) and Real-Time Radiography (RTR) remain valuable, the addition of robotic systems, sensors, and AI are transforming CUI inspection.

Robotic systems, sensors, and AI are reshaping how CUI inspections are conducted, reducing reliance on manual labor and enabling broader, data-rich asset visibility for better planning and decision-making.

ARIX Technologies, for example, introduced pipe-climbing robotic systems capable of full-coverage inspections of insulated pipes without the need for insulation removal. Venus, ARIX’s pipe-climbing robot, delivers full 360° CUI data across both vertical and horizontal pipe circuits — without magnets, scaffolding, or insulation removal. It captures high-resolution visuals and Pulsed Eddy Current (PEC) data simultaneously, allowing operators to review inspection video and analyze corrosion insights in one integrated workflow. This streamlines data collection, speeds up analysis, and keeps personnel out of hazardous zones — making inspections faster, safer, and far more actionable.

These integrated technology platforms are driving measurable gains:

  • Autonomous grid scanning: Delivers structured, repeatable coverage across pipe surfaces for greater inspection consistency.
  • Integrated inspection portal: Combines PEC, RTR, and video into a unified 3D visualization, streamlining analysis across inspection teams.
  • Actionable insights: Enables more confident planning and risk forecasting through digital, shareable data—not siloed or static.

Real-world results

Petromax Refining adopted ARIX’s robotic inspection systems to modernize its CUI inspections, and its results were substantial and measurable:

  • Inspection time dropped from nine months to 39 days.
  • Costs were cut by 63% compared to traditional methods.
  • Scaffolding was minimized 99%, reducing hazardous risks and labor demands.
  • Data accuracy improved, supporting more innovative maintenance planning.

Why the time is now

Energy operators face mounting pressure from all sides: aging infrastructure, constrained budgets, rising safety risks, and growing ESG expectations.

In the U.S., downstream operators are increasingly piloting drone and crawler solutions to automate inspection rounds in refineries, tank farms, and pipelines. Over 92% of oil and gas companies report that they are investing in AI or robotic technologies or have plans to invest soon to modernize operations.

The tools are here. The data is here. Smarter inspection is no longer aspirational — it’s operational. The case has been made. Petromax and others are showing what’s possible. Smarter inspection is no longer a leap but a step forward.

Scientists warn greenhouse gas accumulation is accelerating and more extreme weather will come

Climate Report

Humans are on track to release so much greenhouse gas in less than three years that a key threshold for limiting global warming will be nearly unavoidable, according to a study released June 19.

The report predicts that society will have emitted enough carbon dioxide by early 2028 that crossing an important long-term temperature boundary will be more likely than not. The scientists calculate that by that point there will be enough of the heat-trapping gas in the atmosphere to create a 50-50 chance or greater that the world will be locked in to 1.5 degrees Celsius (2.7 degrees Fahrenheit) of long-term warming since preindustrial times. That level of gas accumulation, which comes from the burning of fuels like gasoline, oil and coal, is sooner than the same group of 60 international scientists calculated in a study last year.

“Things aren’t just getting worse. They’re getting worse faster,” said study co-author Zeke Hausfather of the tech firm Stripe and the climate monitoring group Berkeley Earth. “We’re actively moving in the wrong direction in a critical period of time that we would need to meet our most ambitious climate goals. Some reports, there’s a silver lining. I don’t think there really is one in this one.”

That 1.5 goal, first set in the 2015 Paris agreement, has been a cornerstone of international efforts to curb worsening climate change. Scientists say crossing that limit would mean worse heat waves and droughts, bigger storms and sea-level rise that could imperil small island nations. Over the last 150 years, scientists have established a direct correlation between the release of certain levels of carbon dioxide, along with other greenhouse gases like methane, and specific increases in global temperatures.

In Thursday's Indicators of Global Climate Change report, researchers calculated that society can spew only 143 billion more tons (130 billion metric tons) of carbon dioxide before the 1.5 limit becomes technically inevitable. The world is producing 46 billion tons (42 billion metric tons) a year, so that inevitability should hit around February 2028 because the report is measured from the start of this year, the scientists wrote. The world now stands at about 1.24 degrees Celsius (2.23 degrees Fahrenheit) of long-term warming since preindustrial times, the report said.

Earth's energy imbalance

The report, which was published in the journal Earth System Science Data, shows that the rate of human-caused warming per decade has increased to nearly half a degree (0.27 degrees Celsius) per decade, Hausfather said. And the imbalance between the heat Earth absorbs from the sun and the amount it radiates out to space, a key climate change signal, is accelerating, the report said.

“It's quite a depressing picture unfortunately, where if you look across the indicators, we find that records are really being broken everywhere,” said lead author Piers Forster, director of the Priestley Centre for Climate Futures at the University of Leeds in England. “I can't conceive of a situation where we can really avoid passing 1.5 degrees of very long-term temperature change.”

The increase in emissions from fossil-fuel burning is the main driver. But reduced particle pollution, which includes soot and smog, is another factor because those particles had a cooling effect that masked even more warming from appearing, scientists said. Changes in clouds also factor in. That all shows up in Earth’s energy imbalance, which is now 25% higher than it was just a decade or so ago, Forster said.

Earth’s energy imbalance “is the most important measure of the amount of heat being trapped in the system,” Hausfather said.

Earth keeps absorbing more and more heat than it releases. “It is very clearly accelerating. It’s worrisome,” he said.

Crossing the temperature limit

The planet temporarily passed the key 1.5 limit last year. The world hit 1.52 degrees Celsius (2.74 degrees Fahrenheit) of warming since preindustrial times for an entire year in 2024, but the Paris threshold is meant to be measured over a longer period, usually considered 20 years. Still, the globe could reach that long-term threshold in the next few years even if individual years haven't consistently hit that mark, because of how the Earth's carbon cycle works.

That 1.5 is “a clear limit, a political limit for which countries have decided that beyond which the impact of climate change would be unacceptable to their societies,” said study co-author Joeri Rogelj, a climate scientist at Imperial College London.

The mark is so important because once it is crossed, many small island nations could eventually disappear because of sea level rise, and scientific evidence shows that the impacts become particularly extreme beyond that level, especially hurting poor and vulnerable populations, he said. He added that efforts to curb emissions and the impacts of climate change must continue even if the 1.5 degree threshold is exceeded.

Crossing the threshold "means increasingly more frequent and severe climate extremes of the type we are now seeing all too often in the U.S. and around the world — unprecedented heat waves, extreme hot drought, extreme rainfall events, and bigger storms,” said University of Michigan environment school dean Jonathan Overpeck, who wasn't part of the study.

Andrew Dessler, a Texas A&M University climate scientist who wasn't part of the study, said the 1.5 goal was aspirational and not realistic, so people shouldn’t focus on that particular threshold.

“Missing it does not mean the end of the world,” Dessler said in an email, though he agreed that “each tenth of a degree of warming will bring increasingly worse impacts.”
