Sean Marshall and Danny Rehg founded Criterion Energy Partners in 2020 with the hope that geothermal energy could be the cleaner, safer wave of the future. Less than three years later, the team is close to making their plan a reality thanks to a geothermal well that they hope to drill this year.

Entrepreneurship wasn’t always part of the plan for either partner. When Marshall enrolled in the MBA program at Rice University’s Jones School of Business in 2016, he had a successful career at Credit Suisse and had his eye set on a future political career. But then he met classmate Rehg, whose background was in petroleum engineering. Their wives were both attorneys in the Houston district attorney’s office and the couples became fast friends. They also realized that, as Marshall now puts it, Rehg knew how to drill wells and he knew how to make deals.

In the ensuing years, both Rehg and Marshall's careers evolved and, eventually, the pair started looking for other opportunities. That’s when they read an article in Rolling Stone about geothermal energy.

“It was really a place where it really felt like this was something we were put here to do,” says Marshall.

Marshall and Rehg spent the ensuing months “like rats in a dumpster” learning about the players and opportunities in the geothermal industry and built from there. They learned about Pleasant Bayou Power Plant, a 1989 geothermal energy project based in Brazoria County that was backed by the U.S. Department of Energy.

Last summer, Criterion Energy Partners, a member of Greentown Houston, closed on a 10,000-acre lease around the site of Pleasant Bayou.

"We hope by the end of this year we will be generating electrons,” says Marshall.

Though the company has a patented technology that connects wells to the grid, called Criterion Geothermal System, Marshall says that some of the best advice he’s gotten was, “Don’t fall in love with your technology; fall in love with the problem.” The 2021 Texas freeze reminded the founders what that was.

“People were looking for cleaner, lower-emission power sources and [there was] a need for energy resiliency,” says Marshall, explaining that the freeze created an ideal situation for the company, as people began to think more outside the grid.

The year 2022 was a big one for Criterion Energy Partners. Oil and gas powerhouse Patterson-UTI invested in the company, followed by funding from the Department of Energy. The money not only allowed Criterion Energy Partners to lease their land, they are also now paying 12 salaries, including those of the founders. The team offices in The Cannon’s Esperson coworking space.

“Our mission is to make geothermal commercially viable everywhere,” says Marshall. “I still believe in that.”

However, Criterion Energy Partners may be even bigger than proving an alternative energy source. Marshall says that geothermal is the foundation on which they are building “a next-generation energy company.” Criterion Energy Partners could be the more stable basis for a whole new energy system.

This energy transition startup taps Houston to grow, build its waste-heat-to-power tech

eyes on hou

Waste heat is everywhere, but in Houston, the Energy Capital of the World, it is becoming a hot commodity. What is it? Janice Tran, CEO of Kanin Energy, uses the example of turning ore into steel.

“There’s a lot of heat involved in that chemical process,” she says. “It’s a waste of energy.”

But Kanin Energy can do something about that. Its waste-heat-to-power, or WHP, concept uses a technology called organic rankine cycle. Tran explains that heat drives a turbine that generates electricity.

“It’s a very similar concept to a steam engine,” she says. Tran adds that the best term for what Kanin Energy does is “waste heat recovery.”

Emission-free power should be its own virtuous goal, but for companies creating waste heat, it can be an expensive endeavor both in terms of capital and human resources to work on energy transition solutions. But Kanin Energy helps companies to decarbonize with no cost to them.

“We can pay for the projects, then we pay the customers for that heat. We turn a waste product into a revenue stream for our customer,” Tran explains. Kanin Energy then sells the clean power back to the facility or to the grid, hence decarbonizing the facility gratis. Financing, construction, and operations are all part of the package.

Kanin Energy began at the height of the COVID-19 pandemic, in the spring of 2020.

“We started like a lotus. A lotus grows in mud — you start in the worst conditions and everything is better and easier from there,” says Tran.

That tough birth has helped provide the team with a discipline and thoughtfulness that’s been key to the company’s culture. Remote work has forced the team to get procedures clearly in place and react efficiently.

Back in May of 2020, its inception took place in Calgary. But the team, which also includes CDO Dan Fipke and CTO Jake Bainbridge, began to notice that many of their customers were either based in Houston or had Houston ties.

A year ago, the Kanin team visited Houston to see if the city could be a fit for an office. In July of 2022, Tran opened Kanin Energy offices in Greentown Labs.

“We’re hiring and building our team office out of Greentown. It’s been really great for us,” she says.

With the company now in its commercialization stage, Tran says that becoming part of the Houston energy ecosystem has been invaluable for Kanin.

The investments being made in climate tech and in energy transition make Space City the right place for the company. For Canadian-born Kanin Energy, Houston is now home. Investors across the nation, including Texas, are now helping Kanin to blossom, much like the lotus.

Houston researchers make headway on developing low-cost sodium-ion batteries

energy storage

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”

ExxonMobil lands major partnership for clean hydrogen facility in Baytown

power deal

Exxon Mobil and Japanese import/export company Marubeni Corp. have signed a long-term offtake agreement for 250,000 tonnes of low-carbon ammonia per year from ExxonMobil’s forthcoming facility in Baytown, Texas.

“This is another positive step forward for our landmark project,” Barry Engle, president of ExxonMobil Low Carbon Solutions, said in a news release. “By using American-produced natural gas we can boost global energy supply, support Japan’s decarbonization goals and create jobs at home. Our strong relationship with Marubeni sets the stage for delivering low-carbon ammonia from the U.S. to Japan for years to come."

The companies plan to produce low-carbon hydrogen with approximately 98% of CO2 removed and low-carbon ammonia. Marubeni will supply the ammonia mainly to Kobe Power Plant, a subsidiary of Kobe Steel, and has also agreed to acquire an equity stake in ExxonMobil’s low-carbon hydrogen and ammonia facility, which is expected to be one of the largest of its kind.

The Baytown facility aims to produce up to 1 billion cubic feet daily of “virtually carbon-free” hydrogen. It can also produce more than 1 million tons of low-carbon ammonia per year. A final investment decision is expected in 2025 that will be contingent on government policy and necessary regulatory permits, according to the release.

The Kobe Power Plant aims to co-fire low-carbon ammonia with existing fuel, and reduce CO2 emissions by Japan’s fiscal year of 2030. Marubeni also aims to assist the decarbonization of Japan’s power sector and steel manufacturing industry, chemical industry, transportation industry and various others sectors.

“Marubeni will take this first step together with ExxonMobil in the aim of establishing a global low-carbon ammonia supply chain for Japan through the supply of low-carbon ammonia to the Kobe Power Plant,” Yoshiaki Yokota, senior managing executive officer at Marubeni Corp., added in the news release. “Additionally, we aim to collaborate beyond this supply chain and strive towards the launch of a global market for low-carbon ammonia. We hope to continue to actively cooperate with ExxonMobil, with a view of utilizing this experience and relationship we have built to strategically decarbonize our power projects in Japan and Southeast Asia in the near future.”

Houston expert: The role of U.S. LNG in global energy markets

guest column

The debate over U.S. Liquefied Natural Gas (LNG) exports is too often framed in misleading, oversimplified terms. The reality is clear: LNG is not just a temporary fix or a bridge fuel, it is a fundamental pillar of global energy security and economic stability. U.S. LNG is already reducing coal use in Asia, strengthening Europe’s energy balance, and driving economic growth at home. Turning away from LNG exports now would be a shortsighted mistake, undermining both U.S. economic interests and global energy security.

Ken Medlock, Senior Director of the Baker Institute’s Center for Energy Studies, provides a fact-based assessment of the U.S. LNG exports that cuts through the noise. His analysis, consistent with McKinsey work, confirms that U.S. LNG is essential to balancing global energy markets for the decades ahead. While infrastructure challenges and environmental concerns exist, the benefits far outweigh the drawbacks. If the U.S. fails to embrace its leadership in LNG, we risk giving up our position to competitors, weakening our energy resilience, and damaging national security.

LNG Export Licenses: Options, Not Guarantees

A common but deeply flawed argument against expanding LNG exports is the assumption that granting licenses guarantees unlimited exports. This is simply incorrect. As Medlock puts it, “Licenses are options, not guarantees. Projects do not move forward if they are unable to find commercial footing.”

This is critical: government approvals do not dictate market outcomes. LNG projects must navigate economic viability, infrastructure feasibility, and global demand before becoming operational. This reality should dispel fears that expanded licensing will automatically lead to an uncontrolled surge in exports or domestic price spikes. The market, not government restrictions, should determine which projects succeed.

Canada’s Role in U.S. Gas Markets

The U.S. LNG debate often overlooks an important factor: pipeline imports from Canada. The U.S. and Canadian markets are deeply intertwined, yet critics often ignore this reality. Medlock highlights that “the importance to domestic supply-demand balance of our neighbors to the north and south cannot be overstated.”

Infrastructure Constraints and Price Volatility

One of the most counterproductive policies the U.S. could adopt is restricting LNG infrastructure development. Ironically, such restrictions would not only hinder exports but also drive up domestic energy prices. Medlock’s report explains this paradox: “Constraints that either raise development costs or limit the ability to develop infrastructure tend to make domestic supply less elastic. Ironically, this has the impact of limiting exports and raising domestic prices.”

The takeaway is straightforward: blocking infrastructure development is a self-inflicted wound. It stifles market efficiency, raises costs for American consumers, and weakens U.S. competitiveness in global energy markets. McKinsey research confirms that well-planned infrastructure investments lead to greater price stability and a more resilient energy sector. The U.S. should be accelerating, not hindering, these investments.

Short-Run vs. Long-Run Impacts on Domestic Prices

Critics of LNG exports often confuse short-term price fluctuations with long-term market trends. This is a mistake. Medlock underscores that “analysis that claims overly negative domestic price impacts due to exports tend to miss the distinction between short-run and long-run elasticity.”

Short-term price shifts are inevitable, driven by seasonal demand and supply disruptions. But long-term trends tell a different story: as infrastructure improves and production expands, markets adjust, and price impacts moderate. McKinsey analysis suggests supply elasticity increases as producers respond to price signals. Policy decisions should be grounded in this broader economic reality, not reactionary fears about temporary price movements.

Assessing the Emissions Debate

The argument that restricting U.S. LNG exports will lower global emissions is fundamentally flawed. In fact, the opposite is true. Medlock warns against “engineering scenarios that violate basic economic principles to induce particular impacts.” He emphasizes that evaluating emissions must be done holistically. “Constraining U.S. LNG exports will likely mean Asian countries will continue to turn to coal for power system balance,” a move that would significantly increase global emissions.

McKinsey’s research reinforces that, on a lifecycle basis, U.S. LNG produces fewer emissions than coal. That said, there is room for improvement, and efforts should focus on minimizing methane leakage and optimizing gas production efficiency.

However, the broader point remains: restricting LNG on environmental grounds ignores the global energy trade-offs at play. A rational approach would address emissions concerns while still recognizing the role of LNG in the global energy system.

The DOE’s Commonwealth LNG Authorization

The Department of Energy’s recent conditional approval of the Commonwealth LNG project is a step in the right direction. It signals that economic growth, energy security, and market demand remain key considerations in regulatory decisions. Medlock’s analysis makes it clear that LNG exports will be driven by market forces, and McKinsey’s projections show that global demand for flexible, reliable LNG is only increasing.

The U.S. should not limit itself with restrictive policies when the rest of the world is demanding more LNG. This is an opportunity to strengthen our position as a global energy leader, create jobs, and ensure long-term energy security.

Conclusion

The U.S. LNG debate must move beyond fear-driven narratives and focus on reality. The facts are clear: LNG exports strengthen energy security, drive economic growth, and reduce global emissions by displacing coal.

Instead of restrictive policies that limit LNG’s potential, the U.S. should focus on expanding infrastructure, maintaining market flexibility, and supporting innovation to further reduce emissions. The energy transition will be shaped by market realities, not unrealistic expectations.

The U.S. has an opportunity to lead. But leadership requires embracing economic logic, investing in infrastructure, and ensuring our policies are guided by facts, not political expediency. LNG is a critical part of the global energy landscape, and it’s time to recognize its long-term strategic value.
