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 quantum simulator research reveals clues for solar energy conversion

energy flow

Rice University scientists have used a programmable quantum simulator to mimic how energy moves through a vibrating molecule.

The research, which was published in Nature Communications last month, lets the researchers watch and control the flow of energy in real time and sheds light on processes like photosynthesis and solar energy conversion, according to a news release from the university.

The team, led by Rice assistant professor of physics and astronomy Guido Pagano, modeled a two-site molecule with one part supplying energy (the donor) and the other receiving it (the acceptor).

Unlike in previous experiments, the Rice researchers were able to smoothly tune the system to model multiple types of vibrations and manipulate the energy states in a controlled setting. This allowed the team to explore different types of energy transfer within the same platform.

“By adjusting the interactions between the donor and acceptor, coupling to two types of vibrations and the character of those vibrations, we could see how each factor influenced the flow of energy,” Pagano said in the release.

The research showed that more vibrations sped up energy transfer and opened new paths for energy to move, sometimes making transfer more efficient even with energy loss. Additionally, when vibrations differed, efficient transfer happened over a wider range of donor–acceptor energy differences.

“The results show that vibrations and their environment are not simply background noise but can actively steer energy flow in unexpected ways,” Pagano added.

The team believes the findings could help with the design of organic solar cells, molecular wires and other devices that depend on efficient energy or charge transfer. They could also have an environmental impact by improving energy harvesting to reduce energy losses in electronics.

“These are the kinds of phenomena that physical chemists have theorized exist but could not easily isolate experimentally, especially in a programmable manner, until now,” Visal So, a Rice doctoral student and first author of the study, added in the release.

The study was supported by The Welch Foundation,the Office of Naval Research, the National Science Foundation CAREER Award, the Army Research Office and the Department of Energy.

The EPA is easing pollution rules — here’s how it’s affecting Texas

In the news

The first year of President Trump’s second term has seen an aggressive rollback of federal environmental protections, which advocacy groups fear will bring more pollution, higher health risks, and less information and power for Texas communities, especially in heavily industrial and urban areas.

Within Trump’s first 100 days in office, his new Environmental Protection Agency administrator, Lee Zeldin, announced a sweeping slate of 31 deregulatory actions. The list, which Zeldin called the agency’s “greatest day of deregulation,” targeted everything from soot standards and power plant pollution rules to the Endangerment Finding, the legal and scientific foundation that obligates the EPA to regulate climate-changing pollution under the Clean Air Act.

Since then, the agency froze research grants, shrank its workforce, and removed some references to climate change and environmental justice from its website — moves that environmental advocates say send a clear signal: the EPA’s new direction will come at the expense of public health.

Cyrus Reed, conservation director of the Lone Star Chapter of the Sierra Club, said Texas is one of the states that feels EPA policy changes directly because the state has shown little interest in stepping up its environmental enforcement as the federal government scales back.

“If we were a state that was open to doing our own regulations there’d be less impact from these rollbacks,” Reed said. “But we’re not.”

“Now we have an EPA that isn’t interested in enforcing its own rules,” he added.

Richard Richter, a spokesperson at the state’s environmental agency, Texas Commission on Environmental Quality, said in a statement that the agency takes protecting public health and natural resources seriously and acts consistently and quickly to enforce federal and state environmental laws when they’re violated.

Methane rules put on pause

A major EPA move centers on methane, a potent greenhouse gas that traps heat far more efficiently than carbon dioxide over the short term. It accounts for roughly 16% of global greenhouse gas emissions and is a major driver of climate change. In the U.S., the largest source of methane emissions is the energy sector, especially in Texas, the nation’s top oil and gas producer.

In 2024, the Biden administration finalized long-anticipated rules requiring oil and gas operators to sharply reduce methane emissions from wells, pipelines, and storage facilities. The rule, developed with industry input, targeted leaks, equipment failures, and routine flaring, the burning off of excess natural gas at the wellhead.

Under the rule, operators would have been required to monitor emissions, inspect sites with gas-imaging cameras for leaks, and phase out routine flaring. States are required to come up with a plan to implement the rule, but Texas has yet to do so. Under Trump’s EPA, that deadline has been extended until January 2027 — an 18-month postponement.

Texas doesn’t have a rule to capture escaping methane emissions from energy infrastructure. Richter, the TCEQ spokesperson, said the agency continues to work toward developing the state plan.

Adrian Shelley, Texas director of the watchdog group Public Citizen, said the rule represented a rare moment of alignment between environmentalists and major oil and gas producers.

“I think the fossil fuel industry generally understood that this was the direction the planet and their industry was moving,” he said. Shelley said uniform EPA rules provided regulatory certainty for changes operators saw as inevitable.

Reed, the Sierra Club conservation director, said the delay of methane rules means Texas still has no plan to reduce emissions, while neighboring New Mexico already has imposed its own state methane emission rules that require the industry to detect and repair methane leaks and ban routine venting and flaring.

These regulations have cut methane emissions in the New Mexico portion of the Permian Basin — the oil-rich area that covers West Texas and southeast New Mexico — to half that of Texas, according to a recent data analysis by the Environmental Defense Fund. That’s despite New Mexico doubling production since 2020.

A retreat from soot standards

Fine particulate matter or PM 2.5, one of six pollutants regulated under the Clean Air Act, has been called by researchers the deadliest form of air pollution.

In 2024, the EPA under President Biden strengthened air rules for particulate matter by lowering the annual limit from 12 to 9 micrograms per cubic meter. It was the first update since 2012 and one of the most ambitious pieces of Biden’s environmental agenda, driven by mounting evidence that particulate pollution is linked to premature death, heart disease, asthma, and other respiratory illnesses.

After the rule was issued, 24 Republican-led states, including Kentucky and West Virginia, sued to revert to the weaker standard. Texas filed a separate suit asking to block the rule’s recent expansion.

State agencies are responsible for enforcing the federal standards. The TCEQ is charged with creating a list of counties that exceed the federal standard and submitting those recommendations to Gov. Greg Abbott, who then finalizes the designations and submits them to the EPA.

Under the 9 microgram standard, parts of Texas, including Dallas, Harris (which includes Houston), Tarrant (Fort Worth), and Bowie (Texarkana) counties, were in the process of being designated nonattainment areas — which, when finalized, would trigger a legal requirement for the state to develop a plan to clean up the air.

That process stalled after Trump returned to office. Gov. Greg Abbott submitted his designations to EPA last February, but EPA has not yet acted on his designations, according to Richter, the TCEQ spokesperson.

In a court filing last year, the Trump EPA asked a federal appeals court to vacate the stricter standard, bypassing the traditional notice and comment administrative process.

For now, the rule technically remains in effect, but environmental advocates say the EPA’s retreat undermines enforcement of the rule and signals to polluters that it may be short-lived.

Shelley, with Public Citizen, believes the PM2.5 rule would have delivered the greatest health benefit of any EPA regulation affecting Texas, particularly through reductions in diesel pollution from trucks.

“I still hold out hope that it will come back,” he said.

Unraveling the climate framework

Beyond individual pollutants, the Trump EPA has moved to dismantle the federal architecture for addressing climate change.

Among the proposals is eliminating the Greenhouse Gas Reporting Program, which requires power plants, refineries, and oil and gas suppliers to report annual emissions. The proposal has drawn opposition from both environmental groups and industry, which relies on the data for planning and compliance.

Colin Leyden, Texas state director and energy lead at the nonprofit Environmental Defense Fund, said eliminating the program could hurt Texas industry. If methane emissions are no longer reported, then buyers and investors of natural gas, for example, won’t have an official way to measure how much methane pollution is associated with that gas, according to Leyden. That makes it harder to judge how “clean” or “climate-friendly” the product is, which international buyers are increasingly demanding.

“This isn’t just bad for the planet,” he said. “It makes the Texas industry less competitive.”

The administration also proposed last year rescinding the Endangerment Finding, issued in 2009, which obligates the EPA to regulate climate pollution. Most recently, the EPA said it will stop calculating how much money is saved in health care costs as a result of air pollution regulations that curb particulate matter 2.5 and ozone, a component of smog. Both can cause respiratory and health problems.

Leyden said tallying up the dollar value of lives saved when evaluating pollution rules is a foundational principle of the EPA since its creation.

“That really erodes the basic idea that (the EPA) protects health and safety and the environment,” he said.

New report predicts major data center boom in Texas by 2028

data analysis

Data centers are proving to be a massive economic force in Texas.

For instance, a new report from clean energy company Bloom Energy predicts Texas will see a 142 percent increase in its market share for data centers from 2025 to 2028. That would be the highest increase of any state.

Bloom Energy expects Texas to exceed 40 gigawatts of data-center capacity by 2028, representing a nearly 30 percent share of the U.S. market. A typical AI data center consumes 1 to 2 gigawatts of energy.

“Data center and AI factory developers can’t afford delays,” Natalie Sunderland, Bloom Energy’s chief marketing officer, said in the report. “Our analysis and survey results show that they’re moving into power‑advantaged regions where capacity can be secured faster — and increasingly designing campuses to operate independently of the grid.”

“The surge in AI demand creates a clear opportunity for states that can adapt to support large-scale AI deployments at speed,” Sunderland adds.

Further evidence of the data center explosion in Texas comes from ConstructConnect, a provider of data and software for contractors and manufacturers. ConstructConnect reported that in the 12-month span through November 2025, data-center construction starts in Texas accounted for $11 billion in spending. At $12.5 billion, only Louisiana surpassed the Texas total.

Capital expenses for U.S. data centers were expected to surpass $425 billion last year, according to ratings agency S&P Global.

ConstructConnect also reports that Texas is among five states collectively grabbing 80 percent of potential data center construction starts. Currently, Texas hosts around 400 data centers, with close to 60 of them in the Houston market.

A large pool of data-center construction spending in Texas is flowing from Google, which announced in November that it would earmark $40 billion for new AI data centers in the state.

“Texas leads in AI and tech innovation,” Gov. Greg Abbott proclaimed when the Google investment was unveiled.

Other studies and reports lay out just how much data centers are influencing economic growth in the Lone Star State:

  • A study by Texas Royalty Brokers indicates Texas leads the U.S. with 17 clusters of AI data centers. The study measured the density of AI data centers by counting the number of graphics processing units (GPUs) installed in those clusters. GPUs are specialized chips built to run AI models and perform complex calculations.
  • Citing data from construction consulting company FMI, The Wall Street Journal reported that spending on construction of data centers is expected to rise 23 percent in 2026 compared with last year. Much of that construction spending will happen in Texas. In the 12 months through November 2025, the average data center cost $597 million, according to ConstructConnect.
  • Data published in 2025 by commercial real estate services company Cushman & Wakefield shows three Texas markets — Austin, Dallas and San Antonio — boast the lowest construction costs for data centers among the 19 U.S. markets that were analyzed. The mid-range of costs in that trio of markets is roughly $10.65 million per megawatt. Houston isn’t included in the data.

Although Houston isn’t cited in the Cushman & Wakefield data, it nonetheless is playing a major role in the data-center boom. Houston-area energy giants Chevron and ExxonMobil are chasing opportunities to supply natural gas as a power source for data centers, for example.

“As Houston rapidly evolves into a hub for AI, cloud computing, and data infrastructure, the city is experiencing a surge in data-center investments driven by its unique position at the intersection of energy, technology, and innovation,” says the Greater Houston Partnership.
