Greentown accelerator in partnership with Shell wraps up with startup milestones met

that's a wrap

After six months of incubating with Shell through Greentown Labs, the 2023 Greentown Go Make startup cohort has completed with its recent showcase.

The six participating startups — Caravel Bio, Circularise, Corumat, Lydian, Maple Materials, and Universal Matter — were originally announced in October. The cohort was selected from over 100 applications, and experts from Shell worked to support the cohort as they navigated the program.

Universal Matter, headquartered in Burlington, Ontario, Canada, with a Houston office, is developing a proprietary flash Joule heating process that converts carbon waste into high-value and high-performance graphene materials to efficiently create sustainable, circular economies.

During the program, Universal Matter worked with Shell to identify eight potential collaboration areas across upstream carbon feedstocks, downstream end-use applications for the startup’s graphene, and more, according to a news release from Greentown.

“Go Make 2023 was run with exceptional efficiency to ensure that all startup members were able to gain maximum benefit from exchanges with the corporate partner,” says Universal Matter’s VP of Strategic Planning Peter van Ballegooie.

“The one-on-one exchanges were extremely useful to startups, as they facilitated the connections to the relevant business units within Shell that could potentially benefit from the novel technologies being developed," he continues. "Establishing the connectivity to the right discussion partners within those various business units was absolutely key to the successful outcome of the program.”

Greentown shared more about each of the company's progress throughout the program in a blog post.

The program, which includes $15,000 in non-dilutive stipend funding for each company, will work closely with Shell and Greentown over six months via mentorship, networking opportunities, educational workshops, and partnership-focused programming to support collaboration. Go Make 2023 concludes with a showcase event on March 27 at Greentown Labs’ Houston location.

This week, Shell announced another accelerator cohort it's participating in. The Shell GameChanger Accelerator, a partnership with the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL), named four West Coast climatetech companies: DTE Materials, Hexas Biomass, Invizyne Technologies, and ZILA BioWorks. The program provides early-stage cleantech startups with access to experts and facilities to reduce technology development risk and accelerate commercialization of new cleaner technologies.

“Tackling the climate challenge requires multifaceted solutions. At Shell, we believe technology that removes carbon dioxide from the atmosphere will be essential for lowering emissions from energy and chemical products,” Yesim Jonsson, Shell’s GCxN program manager, says in a statement. “The companies in GCxN's sixth cohort embody these objectives and have the potential to usher in a more sustainable future.”

Energy expert: Houston welcomed the world — can Texas power what's next?

guest column

For a few weeks this summer, Houston welcomed the world.

The FIFA World Cup 2026 showcased our city's ability to host one of the largest international events on the planet. Millions watched from around the globe while hundreds of thousands of visitors experienced firsthand what Houston has become: a world-class destination for business, culture and global events.

But once the final match is played and the visitors return home, a more important question remains: Can Texas build the energy infrastructure needed to power what comes next?

The World Cup wasn't the finish line. It was a glimpse into the future.

That future is being shaped not only by population growth, but also by artificial intelligence, hyperscale data centers, advanced manufacturing, electrification, LNG expansion and continued industrial investment. Together, these forces are creating an unprecedented demand for electricity and placing new expectations on the infrastructure that supports it.

Energy Has Become Economic Infrastructure

For decades, economic development centered around highways, ports, airports and workforce.

Today, another asset has moved to the top of that list: energy infrastructure.

Reliable electricity is no longer simply a utility service. It has become a competitive advantage.

Companies evaluating where to build the next AI campus, manufacturing facility or industrial complex are increasingly asking different questions. How quickly can power be delivered? Is there enough transmission capacity? Can substations support future expansion? Is water infrastructure available? What is the long-term reliability of the local grid?

These questions are becoming just as important as tax incentives and available real estate.

Recent comments from Governor Greg Abbott that future AI developments should provide their own power generation and water illustrate just how dramatically the conversation has evolved. The challenge is no longer limited to meeting today's demand. It is preparing for a future where entirely new industries require unprecedented amounts of electricity while ensuring existing homes and businesses continue to receive reliable, affordable service.

The Next Energy Race Has Already Begun

Texas remains the nation's energy leader, producing more electricity than any other state while continuing to expand natural gas, wind, solar and emerging technologies.

But leadership in the next decade will be measured differently.

Success will depend on how quickly we can expand transmission infrastructure, modernize distribution systems, accelerate interconnection, strengthen grid resilience and support new generation where economic growth is occurring.

The conversation has shifted from producing more electricity to delivering it smarter.

That requires planning years before demand arrives.

Houston Is the Proving Ground

Houston sits at the center of this transformation.

Already recognized as the Energy Capital of the World, the region continues attracting major employers, global headquarters, industrial expansion and technology investment. The Port of Houston continues to grow. Advanced manufacturing is expanding. AI companies are evaluating Texas alongside other national markets.

Every one of these investments depends on reliable infrastructure.

While the World Cup demonstrated Houston's ability to manage a temporary surge of visitors, the more significant challenge lies ahead. Permanent economic growth creates sustained electricity demand that cannot be addressed with temporary solutions.

Meeting that demand will require coordinated investment across generation, transmission, distribution, storage and increasingly, digital technologies capable of forecasting and managing electricity in real time.

Smarter Infrastructure for a Smarter Grid

The future electric grid will look very different from the one that built modern Texas.

Artificial intelligence, predictive analytics, advanced sensors and distributed energy resources will allow operators to anticipate demand, identify equipment failures before they occur and optimize energy delivery across increasingly complex networks.

Infrastructure is no longer simply about building more. It is about building smarter.

At the same time, resilience must remain central to every investment. Texans understand better than most that hurricanes, flooding, winter storms and prolonged heat waves are no longer rare events. Modern infrastructure must not only support growth but also withstand increasingly volatile weather.

Building Beyond the Headlines

The World Cup generated headlines because of what happened on the field.

Its lasting legacy may be what it revealed about the city beyond the stadium.

Houston demonstrated that it can host the world. The next challenge is ensuring it can continue to power one of the fastest-growing economies in North America.

That will require continued investment, thoughtful policy and long-term planning that recognizes energy infrastructure as essential economic infrastructure.

Texas has spent decades leading the world in energy production.

The next opportunity is even greater.

To become the global leader in how energy systems are planned, built and operated for a future defined by artificial intelligence, industrial growth and rapidly evolving consumer demand.

Because the cities that lead tomorrow won't simply generate the most energy.

They'll be the ones best prepared to deliver it where opportunity is growing.

Houston company lands first deal from new Blackstone energy transition fund

M&A activity

Asset manager Blackstone has agreed to buy Houston-based Dresser Utility Solutions from Connecticut private equity firm First Reserve for an undisclosed amount. First Reserve has a major presence in Houston.

The deal represents the first investment from Blackstone Energy Transition Partners V.

“Blackstone’s deep resources and experience in the utility sector make them an ideal partner as we continue to invest in innovation, expand our product portfolio, and deliver value for our customers,” Dresser CEO David Evans said in a news release.

Founded in 1880, Dresser provides metering technology, digital instrumentation and software, pressure and flow controls, and infrastructure repair products for gas and water utilities and industrial customers. The company employs about 850 people worldwide.

“As demands on the energy grid continue to grow, Dresser plays a critical role as a trusted partner to utilities managing essential infrastructure. The company’s products are foundational to the safe and reliable operation of gas and water networks, and its reputation for quality has helped build longstanding customer relationships,” David Foley, global head of Blackstone Energy Transition Partners, and JP Munfa, senior managing director, said in the release.

Blackstone Energy Transition Partners has invested more than $28 billion across the energy transition sector. New York-based Blackstone closed Blackstone Energy Transition Partners Fund IV at $5.6 billion in February 2025. Blackstone Energy Transition Partners Fund III closed in 2020 for $4.4 million, according to Pitchbook.

Other notable energy transition investments from Blackstone funds include Salt Lake City-based Energy Exemplar, French electronics manufacturing company Sediver, Plano-based Westwood Professional Services and others.

Two years ago, Dresser secured a $335 million credit facility from funds managed by asset manager Blue Owl Capital. At the time, Dresser said the money would go toward capital expenses, acquisitions and corporate needs.

This is the second notable investment Blackstone has made in a Houston-based energy company in recent months. In May, Blackstone and energy heavyweight Halliburton made a $1 billion equity investment in Houston power generation startup VoltaGrid, which provides behind-the-meter mobile power generation equipment for data centers, microgrids and industrial customers.
