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.

Houston battery recycling company secures $32M in financing

fresh funding

Houston-based Ace Green Recycling has raised $32 million in private investment in public equity (PIPE) financing to support its future plans for growth.

The battery recycling technology company secured the financing with Athena Technology Acquisition Corp. II, a publicly traded special purpose acquisition company that Ace previously announced it plans to merge with. Once the merger is completed, Ace will become a publicly traded company on the Nasdaq Stock Exchange under the ticker symbol "AGXI."

Ace says the financing will be used to complete the merger and scale the company.

“This investment accelerates our mission to redefine battery recycling at a global scale,” Ace CEO Nischay Chadha said in a news release. “At Ace, we are deploying Greenlead® and LithiumFirst™ as a new standard–fully electrified, Scope 1 emissions-free solutions designed to replace legacy processes and unlock a cleaner supply chain for critical materials. We believe that the future of electrification depends on how efficiently and sustainably we recover these resources, and this milestone brings us meaningfully closer to that future.”

Ace says the funding will also be primarily used to fund capital expenditures related to the development of its planned flagship recycling facility, located outside of Beaumont, Texas. According to a February investor presentation, the facility is expected to launch in 2027. It will recycle lead-acid and lithium-ion batteries.

Ace agreed to a 15-year battery material supply agreement with Miami-based OM Commodities last year, in which OM Commodities would supply Ace with at least 30,000 metric tons of lead scrap to be recycled annually. Switzerland-based Glencore plc agreed to a 15-year offtake agreement to purchase up to 100 percent of ACE’s products from four of its planned lead-acid and lithium-ion battery recycling parks back in 2022.

Ace also reported that the funding will be put toward "supporting the expansion of operations and to fund the purchase of other companies," in the release.

Houston AI startup rolls out platform to reshape oil and gas workflows

AI for energy

Houston-based Collide is looking to solve AI issues in the energy industry from within.

Co-founded by former oil roughneck Collin McLelland, the company has developed AI software for operators and field teams, shaped by firsthand oilfield experience. Its AI-native platform “retrieves and synthesizes data from authoritative sources to deliver accurate, cited, and energy-focused insights to oil and gas professionals,” according to the company.

“Oil and gas has a graveyard full of technology that was technically impressive and operationally useless,” McLelland tells Energy Capital. “The reason is almost always the same: the people who built it didn't understand what they were actually solving for. When you're an outsider, you see workflows and try to automate them. When you're an insider, you understand why those workflows exist—the regulatory constraints, the physical realities, the liability concerns, the trust dynamics between operators and service companies.”

Collide’s large language model, known as RIGGS, performed well in recent benchmarking results when taking a standardized petroleum engineering (SPE) exam, the company reports. The exam assesses understanding from conceptual terminology to complex mathematical problem-solving.

According to Collide, RIGGS achieved a score of 67.5 percent on a 40-question subset of the SPE petroleum engineering exam, outperforming other large language models like Grok 4 (62.5 percent), Claude Sonnet 4.5 (52.5 percent) and GPT 5.1 (4 percent).

RIGGS completed the test in 15 minutes, while Grok took two hours. Collide hopes over the next few months, RIGGS will receive a score between 75 percent to 80 percent accuracy.

The software could potentially help oil and gas companies produce accurate outputs and automate trivial workflows, which can open up valuable time for engineers and teams to work on other pressing matters, according to McLelland.

“Collide exists because we sat in those seats — we were the engineers, the operators, the field guys,” he says. ”RIGGS scoring higher on the PE exam versus the frontier labs isn't a party trick. It's evidence that the model understands petroleum engineering the way a petroleum engineer does, because it was built by people who do.”

RIGGS was trained on Collide’s Spindletop hardware and is supported by a vast library of information, as well as a reasoning engine and validation layer that uses logic to solve problems.

“Longer term, we see RIGGS as the intelligence layer that sits underneath every operator's workflow — not a chatbot you open in a browser, but something embedded in the tools engineers already use,” McLelland says. “The goal is to give every engineer the knowledge and pattern recognition of a 30-year veteran, on demand."

According to McLelland, Collide is already building toward reservoir analysis and production optimization, automated regulatory compliance (Railroad Commission filings, W-10s, G-10s), workover report generation, and engineering decision support in the field for near-term use cases. In March, Collide and Texas-based oil and gas operator Winn Resources announced a collaboration to automate the time-intensive process of filing monthly W-10 and G-10 forms with the Texas Railroad Commission, completing what’s normally a multi-hour task in under 30 minutes. Collide reports that Winn’s infrastructure now automates regulatory filings and provides real-time visibility into data gaps, which has reduced processing time by over 95 percent.

“Before Collide, I'd spend hours manually keying in filings,” Buck Crum, director of operations, said in a news release. “(In March), we had 50 wells to file and I was done in 20 minutes. It does the majority of the heavy lifting while keeping me in control. That human-in-the-loop approach saves meaningful time and gives us greater confidence in our compliance and reporting.”

Collide was originally launched by Houston media organization Digital Wildcatters as “a professional network and digital community for technical discussions and knowledge sharing.” After raising $5 million in seed funding led by Houston’s Mercury Fund last year, the company said it would shift its focus to rolling out its enterprise-level, AI-enabled solution.

Oxy officially announces CEO transition, names successor

new leader

Houston-based Occidental (Oxy) has officially announced its longtime CEO's retirement and her successor.

Oxy shared last week that Vicki Hollub will retire June 1. Reuters first reported Hollub's plan to retire in March, but a firm date had not been set. Hollub will remain on Oxy's board of directors.

Richard Jackson, who currently serves as Oxy's COO, will replace Hollub in the CEO role.

“It has been a privilege to lead Occidental and work alongside such a talented team for more than 40 years," Hollub shared in a news release. "Following the recently completed decade-long transformation of the company, we now have the best portfolio and the best technical expertise in Occidental’s history. With this strong foundation in place, a clear path forward and a leader like Richard, who has the experience and vision to elevate Occidental, now is the right time for this transition. “I look forward to supporting Richard and the Board through my continued role as a director.”

Hollub has held the top leadership position at Oxy since 2016 and has been with the energy giant for more than 40 years. Before being named CEO, she served as COO and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Hollub also played a key role in leading Oxy's future as a "carbon management company."

Jackson has been with Oxy since 2003. He has held numerous leadership positions, including president of U.S. onshore oil and gas, president of low carbon integrated technologies, general manager of the Permian Delaware Basin and enhanced oil recovery oil and gas, vice president of investor relations, and vice president of drilling Americas.

He was instrumental in launching Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others, according to the company. He also serves on the Oil and Gas Climate Initiative’s Climate Investment Board and the American Petroleum Institute’s Upstream Committee. He holds a bachelor's degree in petroleum engineering from Texas A&M University.

Jackson was named COO of Oxy in October 2025. In his new role as CEO, he will also join the board of directors, effective June 1.

“I am grateful to be appointed President and CEO of Occidental and excited about the opportunity to execute from the strong position and capabilities that we built under Vicki’s leadership,” Jackson added in the release. “It means a lot to me personally to be a part of our Occidental team. I am committed to delivering value from our significant and high-quality resource base. We have a tremendous opportunity to focus on organic improvement and execution to deliver meaningful value for our employees, shareholders and partners.”
