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.

Greentown Labs names 6 energy tech startups to Shell-backed accelerator

ready to go make

Greentown Labs has named the six participating climatetech startups for an accelerator for a global energy leader.

Shell and Greentown Labs announced the cohort for Greentown Go Make 2023 — a program designed to accelerate partnerships between startups and corporates to advance carbon utilization, storage, and traceability solutions. Shell, which invests in net-zero and carbon-removal technologies, is hoping to strategically align with startups within carbon utilization, storage, and traceability across the energy transition spectrum.

“At Greentown Labs we recognize and appreciate the role energy incumbents must play in the energy transition, and we’re eager to facilitate meaningful partnerships between these impressive startups and Shell—not only to advance these technologies but also to help Shell achieve its sustainability goals,” Kevin Knobloch, CEO and President of Greentown Labs, says in a news release. “We know carbon utilization, storage, and traceability will play a critical role in our collective efforts to reach net-zero, and we’re enthusiastic about the potential impact these companies can have in that work.”

The cohort, selected from 110 applications, is co-located at Greentown's Houston and Somerville, Massachusetts, locations and includes:

  • Portland-based Caravel Bio is developing a novel synthetic biology platform that uses microbial spores and enzymes to create catalysts that are long-lasting and can withstand extreme conditions and environments.
  • Circularise, which is based in the Netherlands, is developing a blockchain platform that provides digital product passports for end-to-end traceability and secure data exchange for industrial supply chains.
  • Corumat, based in Washington, converts organic waste into high-performance, insulating, greaseproof, and biodegradable packaging materials.
  • Cambridge, Massachusetts-headquartered Lydian develops a fully electrified reactor that can convert a variety of gaseous, non-fossil feedstocks into pure syngas with high efficiency.
  • Maple Materials from Richmond, California is developing a low-cost electrolysis process to split carbon dioxide into graphite and oxygen.
  • Ontario, Canada-founded Universal Matter develops a proprietary Flash Joule Heating process that converts carbon waste into high-value and high-performance graphene materials to efficiently create sustainable circular economies.

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.”

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.”

Texas data center proposed by U.S. Army could use more power than El Paso

Big Data

The U.S. Army is proposing developing a gargantuan, 3-gigawatt data center complex on Fort Bliss property that within a few years would consume more electricity than all of El Paso Electric’s 460,000 customers combined – even as questions about its development, water usage and air pollution remain unanswered.

If built, it would be the third major data center project in the El Paso region, along with Meta Platform’s $10 billion facility in Northeast and the $165 billion Project Jupiter campus that Oracle and OpenAI are building in Santa Teresa, New Mexico. The combined scale and size of the three facilities could quickly transform the Borderland into one of the nation’s core hubs of power generation and AI infrastructure.

The publicly-traded investment firm Carlyle Group would pay to build and operate the Fort Bliss data center – one of several planned in a national rollout under President Donald Trump’s administration to rapidly increase artificial intelligence technology for the Department of Defense.

At Fort Bliss, the Army is “targeting an initial operating capacity of about 100 megawatts on the compute side” by next year, David Fitzgerald, deputy undersecretary of the Army, said during a meeting with reporters April 22. An official estimated cost for the project has yet to be released.

By 2029, the complex on military land in far East El Paso would require 3 gigawatts of electricity, Fitzgerald said. By comparison, El Paso Electric currently maintains about 2.9 gigawatts of generation capacity across its entire system that spans from Hatch, New Mexico, to Van Horn, Texas. The highest customer demand the power company has ever seen was just over 2.3 gigawatts during the summer of 2023.

And whether most El Pasoans are on board with the rapid buildout of another data center here is not a question that Army leadership is asking at this point.

“What we’re trying to do is find where are the common interests, common ground that we can solve for?” Fitzgerald said, referring to coordinating with El Paso city leaders on the data center project.

“The state of modern warfare and future warfare is largely going to depend on the ability to capture, process and utilize massive amounts of data,” he said. “So, the reality is, this is a strategic priority, not just for the Army, but for the entire Department of War. So, we need these capabilities, and we need to put them somewhere.”

Combined-cycle natural gas turbines are the “most likely” source of electricity generation for the facility, said Jeff Waksman, an assistant secretary of the Army and former member of Trump’s first administration.

Waksman said the facility would undergo environmental review before construction starts.

Still, there are far more outstanding questions than answers about the proposed Fort Bliss data center.

It’s unclear if the facility would connect to El Paso Water’s water system. The city-owned water utility pointed out that Fort Bliss Water provides water service for the installation. However, El Paso Water can provide “backup” service to the base, according to the project solicitation documents.

“EPWater was just recently brought into the discussion, and we only have preliminary information,” El Paso Water said in a statement. “The construction and water use would be entirely on federal property.”

El Paso Electric said it’s also uncertain whether the data center will connect to the utility’s power grid and will figure that out in the future. To date, the Army hasn’t made a formal request for service from El Paso Electric.

Officials from the U.S. Army “confirmed that questions regarding the power source and whether it will be connected to the regional grid remain under review and have plans to establish a data center with a projected demand of 3 gigawatts,” El Paso Electric said in a statement. “Ultimately, decisions about these matters will be made by Fort Bliss leadership, and we defer to them for further comment.”

A representative with Carlyle Group at a recent community meeting didn’t answer questions or provide details about the proposed data center facility and the related power generation source.

Carlyle Group did not respond to a request for comment.

Army officials said they don’t yet have a definitive agreement in place with Carlyle, which was conditionally selected to enter into exclusive negotiations, so few details are finalized.

However, the Army has set a short timeline to start operating by late 2027. That means construction will have to start soon, Fitzgerald said.

“The ideal endstate is that we would be at least (operational) by the end of ’27, which is moving pretty quick,” Fitzgerald said. “That would mean construction would need to begin in the not-so-distant future.”

Water, electricity concerns

Meeting three gigawatts of electricity demand with natural gas-fired turbines – cited by Army officials as the most likely power source – would likely produce huge amounts of greenhouse gases in a central area of El Paso, such as carbon dioxide, as well as other harmful pollutants including particulate matter.

And even if the data center doesn’t take service from El Paso Water and instead receives water from wells managed by Fort Bliss, it would rely on groundwater pumped out of the Hueco Bolson aquifer, the city’s main source of water.

The solicitation issued by the Army cites water risk for El Paso as “extremely high” and notes that most of Fort Bliss’ water supply comes from wells within the installation.

Fitzgerald said the Army is aware of the public’s concern that the data center could unsustainably guzzle El Paso’s groundwater to cool the data center’s computer servers. He said the facility will be “water neutral.”

It’s also not clear how the project could replace the same amount of water that it consumes.

It’s possible the Kay Bailey Hutchison Desalination Plant – co-owned by El Paso Water and the U.S. Army – could play a role in making the data center water neutral. But El Paso Water said it has no details about how the data center facility could achieve water neutrality.

El Paso Water is “more than willing to continue to share ideas for best practices in sustainability to help protect our regional water resources,” the utility said in its statement.

As far as electricity generation, Army officials said they don’t know if El Paso Electric would build a new power plant to serve the data center. It’s also possible that Carlyle Group or another private company could build its own power generation source for the data center that’s isolated from the power grid El Pasoans use every day.

“We have to decide whether El Paso Electric is going to be the ones building whatever is coming, or if this is going to be some independent power producer,” Waksman said.

El Paso Electric is planning to develop a 366 megawatt power plant made up of over 800 small gas generators to power Meta’s data center. The utility will build more generation in the coming years to meet 1 gigawatt of total demand from Meta’s facility. Meanwhile, as the technology giant Oracle develops Project Jupiter, the company said Monday it is seeking to power the campus using 2.45 gigawatts of fuel cell power systems provided by the company Bloom Energy.

For perspective, 3.45 gigawatts – the combined projected demand of those two major data centers – is enough electricity to power as many as a million homes, depending on the time of day and weather.

The Fort Bliss project would have to meet environmental regulatory requirements, and the developer needs to include a plan for providing utilities and infrastructure needs such as access to the facility, according to a request for proposals issued by the Army in December 2025. Army officials emphasized the project would not impact El Pasoans’ water or electric bills.

Who is Carlyle Group?

Carlyle Group is a global investment management firm that oversees $477 billion of assets from entities such as pension funds.

The company invests that money by buying businesses ranging from wine producers to Asian telecommunications companies, or by developing infrastructure projects such as renewable energy generation and data centers. The company in 2025 posted distributable earnings of nearly $1.7 billion on $4.8 billion in revenue.

The Army wants to build the facility at Fort Bliss in partnership with Carlyle because the installation has a large amount of available, unused land and because of the water and electricity infrastructure already in place in El Paso, Fitzgerald said.

The Carlyle data center planned for El Paso is part of a wider U.S. military effort to quickly build infrastructure that supports the use of artificial intelligence — both on the battlefield and in running its day-to-day operations, according to government documents.

Army officials nodded to the use of AI in drone warfare and targeting systems. And a hyperscale data center facility can also securely house information such as the military’s cloud database that details pay and entitlements for every U.S. soldier, said Maj. Gen. Curtis Taylor, commanding general of the 1st Armored Division and Fort Bliss.

Data centers are “essential parts of power projection,” Taylor said. “But we have to protect those servers. And that’s why there’s great utility in building that infrastructure on military installations.”

The Fort Bliss facility would be located on a plot of land near the intersection of Loop 375 and Montana Avenue. The site is just east of the Camp East Montana immigrant detention facility, and near El Paso Electric’s gas-fired Montana power station.

The plan is for Carlyle to utilize the majority of the data center’s capacity for its business needs, and the military would have access to a more secure portion of the data center for its own uses.

The Army is developing another similar data center project in Dugway, Utah. Other Army bases identified as potential sites include Fort Hood in Texas and Fort Bragg in North Carolina.

The U.S. Air Force in October issued a solicitation saying it is “accepting proposals for the development of Artificial Intelligence data centers,” on unused land at different bases, including in California, Georgia, Arizona and Tennessee. The push was enabled by executive orders signed by Trump that seek to speed up permitting and development timelines for AI data centers.

Would the Fort Bliss data center pay taxes?

A privately-financed data center on Fort Bliss would likely have to pay some taxes – unlike on-base government facilities – but there’s a lot of uncertainty.

Carlyle Group is leasing the land for the data center under an “enhanced use lease” that allows branches of the military to rent under-used land on bases.

Land on federal installations is not subject to state or local taxes. However, the statute that authorizes the U.S. military to lease excess land to private entities says that “the interest of a lessee of property leased under this section may be taxed by State or local governments.”

So, while the land the data center is built on would not be subject to taxation, the structures housing the data center could be subject to local property taxes.

But it depends on how the deal is structured, including factors such as whether Carlyle or the Army ultimately takes ownership of the buildings.

The Army in January awarded a contract to Korean-owned Hanwha Defense USA, which will invest $1.3 billion to develop a munitions factory at a base in Pine Bluff, Arkansas, using an enhanced use lease.

Fitzgerald, the Army undersecretary, acknowledged the public pushback to other data centers such as Meta and Project Jupiter. But he said the Army wants to ensure the project is developed “the right way.”

“There are always elements that will kind of make this an ‘us versus them’ sort of a construct, but I don’t think we view it that way from the Army,” he said. “I think there’s a path here that will benefit not just the installation, but the community as well.”
