Houston startup gears up to deliver geothermal energy

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.

Eyeing demand growth, ERCOT calls for energy investments across Texas

report

With the Electric Reliability Council of Texas forecasting a big spike in demand for electricity over the next five to seven years, the operator of Texas’ massive power grid is embracing changes that it says will yield a “tremendous opportunity” for energy investments across the state.

The council, known as ERCOT, now estimates an extra 40,000 megawatts of growth in demand for electricity by 2030 compared with last year’s outlook. According to ERCOT data, 40,000 megawatts of electricity would power roughly 8 million Texas homes during peak demand.

ERCOT has been under intense scrutiny in the wake of recent summertime and wintertime debacles involving power emergencies or outages. The organization manages 90 percent of Texas’ power supply.

“As a result of Texas’ continued strong economic growth, new load is being added to the ERCOT system faster and in greater amounts than ever before,” Pablo Vegas, president and CEO of ERCOT, says in a news release. “As we develop and implement the tools provided by the prior two [legislative sessions], ERCOT is positioned to better plan for and meet the needs of our incredibly fast-growing state.”

Meeting the increased demand will create opportunities for energy investments in Texas, says ERCOT. These opportunities will undoubtedly lie in traditional energy production as well as in renewable energy segments such as solar, wind, and “green” hydrogen.

Some of the opportunities might be financed, at least in part, by the newly established Texas Energy Fund. The fund, which has been allotted $5 billion for 2025-26, will provide loans and grants for construction, maintenance, modernization, and operation of power-generating facilities in Texas.

ERCOT is also working with partners to develop tools aimed at improving grid reliability and market efficiency.

ERCOT says changes in its operations that’ll be required to fulfill heightened demand for power will position the nonprofit organization “as a significant component of the economic engine driving the national economy.”

Katy-based US Silica agrees to go private in $1.85B acquisition by asset management firm

M&A move

U.S. Silica has agreed to go private in an all-cash acquisition by Apollo Global Management, a New York asset management firm that primarily invests in alternative assets. The deal values the industrial minerals company at about $1.85 billion.

In a Friday announcement, U.S. Silica said that shareholders would receive $15.50 in cash for each share owned as of the deal's closing. Once the deal closes, U.S. Silica's stock will no longer be listed on the New York Stock Exchange.

Founded in the late 1800s, U.S. Silica produces commercial silica used in the oil and gas industry and other industrial applications. It operates 26 mines and processing facilities and two additional exploration stage properties.

The Katy, Texas-based company is still set to operate under the U.S. Silica name and brand, and will continue to be led by its current CEO Bryan Shinn. In a prepared statement, Shinn said that partnering with Apollo will give U.S. Silica “significant resources, deep industry expertise and enhanced flexibility as a private company."

U.S. Silica said that the transaction — which has been unanimously approved by its board of directors — is expected to close in the third quarter, subject to regulatory approval and other customary conditions.

The agreement also includes a 45-day “go-shop” period that allows U.S. Silica to seek out other proposals until June 10.

Shares of U.S. Silica Holdings Inc. climbed nearly 20 percent Friday morning, shortly after the company reported net income of $13.7 million for its first quarter. The commercial silica producer posted revenue of $325.9 million in the period.

Apollo Global Management's stock was up about 0.18 percent.

From events to a new climate-focused report, here are 3 things to know in Houston energy transition news

take note

Editor's note: Dive headfirst into the new week with three quick things to catch up on in Houston's energy transition: a roundup of events not to miss, a new study puts a dollar sign to Texas' disasters per capita, and three organizations are teaming up for an August event.

When it comes to weather-related events, Texas is expensive

Texas — home to everything from tornadoes to hurricanes — cracks the top 10 of a new report ranking states based on impact from weather-related events.

SmartAsset's new report factored in a myriad of data from the Federal Emergency Management Agency to identify which states face the most financial risk due to various weather events. In the report, the states were ranked by the total expected annual financial losses per person. Texas ranked at No. 10. In Texas, the total expected annual loss per person is estimated as $283.15.

3 organizations in Houston receive funding for DOE-backed programming

Later this year, a Wells Fargo Foundation-backed event that's co-administered by the United States Department of Energy's National Renewable Energy Laboratory will feature programming from three Houston organizations.

The Wells Fargo Innovation Incubator, a $50 million program, announced its eighth cycle of IN2 Channel Partner Strategic Awards. The program is distributing $767,000 across 15 organizations within the Channel Partner network to create impactful workshops at the upcoming Camp Cleantech event in August at CSU Spur in Denver, Colorado.

Houston-based Rice Alliance Clean Energy Accelerator, as well as Activate Global and Greentown Labs, which each have Houston locations, have been named among the awards recipients. The organizations will present workshops aimed at providing critical tools and insights for clean tech startups. Read more about the event and grants.
