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.

3 Houston clean energy startups advance in Elon Musk-backed cleantech competition

finalists

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."

ExxonMobil revs up EV pilot in Permian Basin

seeing green

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."

The EV rollout comes after the company announced last year that it plans to be a major supplier of lithium for EV battery technology.

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.

Houston expert analyzes women's role, challenges in the energy industry

guest column

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.

Houston tech co. to build powerful supercomputer for global energy business to help reach net-zero goals

getting upgraded

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.

Column: Houston expert on what the path to net-zero will look like

guest column

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.

Syzygy partners with fellow Houston co. on sustainable aviation fuel facility

SAF production

Houston-based Syzygy Plasmonics has announced a partnership with Velocys, another Houston company, on its first-of-its-kind sustainable aviation fuel (SAF) production project in Uruguay.

Velocys was selected to provide Fischer-Tropsch technology for the project. Fischer-Tropsch technology converts synthesis gas into liquid hydrocarbons, which is key for producing synthetic fuels like SAF.

Syzygy estimates that the project, known as NovaSAF 1, will produce over 350,000 gallons of SAF annually. It is backed by Uruguay’s largest dairy and agri-energy operations, Estancias del Lago, with permitting and equipment sourcing ongoing. Syzygy hopes to start operations by 2027.

"This project proves that profitable SAF production doesn't have to wait on future infrastructure," Trevor Best, CEO of Syzygy Plasmonics, said in a news release. "With Velocys, we're bringing in a complete, modular solution that drives down overall production costs and is ready to scale. Uruguay is only the start."

The NovaSAF 1 facility will convert dairy waste and biogas into drop-in jet fuel using renewable electricity and waste gas via its light-driven GHG e-Reforming technology. The facility is expected to produce SAF with at least an 80 percent reduction in carbon intensity compared to Jet A fuel.

Syzygy will use Velocys’ microFTL technology to convert syngas into high-yield jet fuel. Velocys’ microFTL will help maximize fuel output, which will assist in driving down the cost required to produce synthetic fuel.

"We're proud to bring our FT technology into a project that's changing the game," Matthew Viergutz, CEO of Velocys, added in the release. "This is what innovation looks like—fast, flexible, and focused on making SAF production affordable."

How carbon capture works and the debate about whether it's a future climate solution

Energy Transition

Power plants and industrial facilities that emit carbon dioxide, the primary driver of global warming, are hopeful that Congress will keep tax credits for capturing the gas and storing it deep underground.

The process, called carbon capture and sequestration, is seen by many as an important way to reduce pollution during a transition to renewable energy.

But it faces criticism from some conservatives, who say it is expensive and unnecessary, and from environmentalists, who say it has consistently failed to capture as much pollution as promised and is simply a way for producers of fossil fuels like oil, gas and coal to continue their use.

Here's a closer look.

How does the process work?

Carbon dioxide is a gas produced by burning of fossil fuels. It traps heat close to the ground when released to the atmosphere, where it persists for hundreds of years and raises global temperatures.

Industries and power plants can install equipment to separate carbon dioxide from other gases before it leaves the smokestack. The carbon then is compressed and shipped — usually through a pipeline — to a location where it’s injected deep underground for long-term storage.

Carbon also can be captured directly from the atmosphere using giant vacuums. Once captured, it is dissolved by chemicals or trapped by solid material.

Lauren Read, a senior vice president at BKV Corp., which built a carbon capture facility in Texas, said the company injects carbon at high pressure, forcing it almost two miles below the surface and into geological formations that can hold it for thousands of years.

The carbon can be stored in deep saline or basalt formations and unmineable coal seams. But about three-fourths of captured carbon dioxide is pumped back into oil fields to build up pressure that helps extract harder-to-reach reserves — meaning it's not stored permanently, according to the International Energy Agency and the U.S. Environmental Protection Agency.

How much carbon dioxide is captured?

The most commonly used technology allows facilities to capture and store around 60% of their carbon dioxide emissions during the production process. Anything above that rate is much more difficult and expensive, according to the IEA.

Some companies have forecast carbon capture rates of 90% or more, “in practice, that has never happened,” said Alexandra Shaykevich, research manager at the Environmental Integrity Project’s Oil & Gas Watch.

That's because it's difficult to capture carbon dioxide from every point where it's emitted, said Grant Hauber, a strategic adviser on energy and financial markets at the Institute for Energy Economics and Financial Analysis.

Environmentalists also cite potential problems keeping it in the ground. For example, last year, agribusiness company Archer-Daniels-Midland discovered a leak about a mile underground at its Illinois carbon capture and storage site, prompting the state legislature this year to ban carbon sequestration above or below the Mahomet Aquifer, an important source of drinking water for about a million people.

Carbon capture can be used to help reduce emissions from hard-to-abate industries like cement and steel, but many environmentalists contend it's less helpful when it extends the use of coal, oil and gas.

A 2021 study also found the carbon capture process emits significant amounts of methane, a potent greenhouse gas that’s shorter-lived than carbon dioxide but traps over 80 times more heat. That happens through leaks when the gas is brought to the surface and transported to plants.

About 45 carbon-capture facilities operated on a commercial scale last year, capturing a combined 50 million metric tons of carbon dioxide — a tiny fraction of the 37.8 gigatonnes of carbon dioxide emissions from the energy sector alone, according to the IEA.

It's an even smaller share of all greenhouse gas emissions, which amounted to 53 gigatonnes for 2023, according to the latest report from the European Commission’s Emissions Database for Global Atmospheric Research.

The Institute for Energy Economics and Financial Analysis says one of the world's largest carbon capture utilization and storage projects, ExxonMobil’s Shute Creek facility in Wyoming, captures only about half its carbon dioxide, and most of that is sold to oil and gas companies to pump back into oil fields.

Future of US tax credits is unclear

Even so, carbon capture is an important tool to reduce carbon dioxide emissions, particularly in heavy industries, said Sangeet Nepal, a technology specialist at the Carbon Capture Coalition.

“It’s not a substitution for renewables ... it’s just a complementary technology,” Nepal said. “It’s one piece of a puzzle in this broad fight against the climate change.”

Experts say many projects, including proposed ammonia and hydrogen plants on the U.S. Gulf Coast, likely won't be built without the tax credits, which Carbon Capture Coalition Executive Director Jessie Stolark says already have driven significant investment and are crucial U.S. global competitiveness.

Houston renewable fuel company expands reach with latest acquisition

fueling up

Houston-based Freedom CNG, a provider and distributor of compressed renewable natural gas, has acquired ComTech Energy, a Canada-based provider of on-site mobile refueling for compressed renewable natural gas. The purchase price wasn’t disclosed.

The acquisition allows Freedom CNG to adopt a hub-and-spoke operational model, allowing customers to move away from fixed fueling infrastructure with low-carbon energy solutions across North America, according to a news release.

In conjunction with the deal, ComTech President James Ro has joined Freedom CNG as chief commercial and strategy officer.

“As we expand our footprint in low‑carbon fuel solutions, acquiring ComTech Energy marks an important step in enhancing our ability to deliver efficient, innovative fueling infrastructure,” Nick Kurtenbach, president and chief financial officer of Freedom CNG, said in the release. The acquisition, he added, “allows us to offer a more comprehensive suite of solutions that support the transition to cleaner energy and meet the evolving needs of our customers.”

Freedom CNG’s North American footprint now spans more than 25 fueling stations for compressed renewable natural gas and over 60 operations and maintenance sites across the U.S. and Canada.

This is the third acquisition for Freedom CNG in the last two months. It also recently acquired Colorado-based X3 CNG and Utah-based Lancer Energy, according to a representative from Freedom CNG, this summer. The company services regional trucks, buses and service vehicles, as well as heavy construction, agriculture, data centers and other sectors.

Last year, funds affiliated with alternative asset manager Apollo bought a majority stake in Freedom CNG, which was founded in 2012. The value of the deal wasn’t disclosed.

“Freedom has developed a strong portfolio of [renewable natural gas] fueling stations with meaningful growth potential driven by established relationships with blue-chip customers and attractive new development opportunities,” Apollo partner Scott Browning said in 2024.
