Houston-based Ara Partners, a private equity firm that focuses on industrial decarbonization investments, is receiving up to $725 million from a Tennessee-based family office to launch an energy decarbonization unit.

HF Capital, the Knoxville, Tennessee-based investment arm of the Haslam family, made the multimillion-dollar commitment to set up Ara Energy Decarbonization. The new business will work toward reducing carbon emissions at ethanol plants, natural gas power plants, and other traditional energy assets.

The Haslam family founded Pilot Co., North America’s largest transportation fuel business and chain of travel centers. Shameek Konar, former CEO of Pilot, has been tapped to lead Ara Energy Decarbonization.

“It is an uncomfortable truth that highly pollutive energy sources are going to play an essential role in delivering an energy transition over the next several decades,” Charles Cherington, co-founder and managing partner of Ara, says in a news release. “We can ignore these staggering carbon emissions, or we can apply our proven methods and financing expertise to decarbonize the conventional energy value chain.”

The energy sector accounts for more than 75 percent of global greenhouse gas emissions.

“The world’s energy demands are increasing and complex, and renewable power needs time and support for it to fulfill rising global energy demand. Ara’s … skillset, portfolio network, and decarbonization management knowledge [are] perfectly positioned to attack the carbon-intensive energy sector,” Konar says.

Ara Partners closed its third private equity fund in December 2023 with over $2.8 billion in new commitments. As of June 30, 2024, Ara Partners had about $6.3 billion of assets under management.

Houston energy tech PE group raises $3B third fund

money moves

A Houston-based private equity firm that focuses on industrial decarbonization investments has closed its latest fund.

Ara Partners has secured over $3 billion of new capital commitments for its Ara Fund III, closing $2.8 billion of limited partner commitments, which represents an oversubscription of its $2 billion initial target.

"We are grateful for the extraordinary interest in Fund III demonstrated by Ara's increasingly global, blue-chip investor base," Charles Cherington, managing partner of Ara, says in a news release. "The strong support from new and existing investors, is a testament to their confidence in our talented team, our investment strategy, and the compelling opportunities in the industrial decarbonization sector."

The third fund's institutional investors includes pension funds, insurance companies, sovereign wealth funds, endowments, and foundations from around the world. Ara Fund III will continue the firm's mission of investing in and buying out decarbonization-aligned industrial companies, specifically targeting ones headquartered in the United States, Canada, and Europe.

"The growing, global presence of Ara's platform and portfolio directly reflects the industrial economy's continued demand for the technological innovation and infrastructure needed to decarbonize," Troy Thacker, managing partner of Ara, says in the release. "The support we have received for Fund III will enable the Ara team to continue investing in high-growth companies globally that are positioned to build value while achieving positive environmental impacts."

The newly closed fund has already made four investments:

Vacuumschmelze, a global producer of advanced magnetic materials and rare earth permanent magnets
Genera, a sustainable pulp and packaging producer
CFP Energy, a provider of market-facing solutions in environmental and green energy products to industrial customers across Europe
CycleØ, a fully integrated developer of distributed biomethane facilities

Founded by Cherington and Thacker in 2017, Ara has around $5.6 billion in assets under management. It's previous fund closed in September 2021 at an oversubscribed $1.1 billion.

Texas could topple Virginia as biggest data-center market by 2030, JLL report says

data analysis

Everything’s bigger in Texas, they say—and that phrase now applies to the state’s growing data-center presence.

A new report from commercial real estate services provider JLL says Texas could overtake Northern Virginia as the world’s largest data-center market by 2030. Northern Virginia is a longtime holder of that title.

What’s driving Texas’ increasingly larger role in the data-center market? The key factor is artificial intelligence.

Companies like Google and Microsoft need more energy-hungry data centers to power AI innovations. In a 2023 article, Forbes explained that AI models consume a lot of energy because of the massive amount of data used to train them, as well as the complexity of those models and the rising volume of tasks assigned to AI.

“The data-center sector has officially entered hyperdrive,” Andy Cvengros, executive managing director at JLL and co-leader of its U.S. data-center business, said in the report. “Record-low vacancy sustained over two consecutive years provides compelling evidence against bubble concerns, especially when nearly all our massive construction pipeline is already pre-committed by investment-grade tenants.”

Dallas-Fort Worth has long dominated the Texas data-center market. But in recent years, West Texas has emerged as a popular territory for building data-center campuses, thanks in large part to an abundance of land and energy. Nearly two-thirds of data-center construction underway now is happening in “frontier markets” like West Texas, Ohio, Tennessee and Wisconsin, the JLL report says.

Northern Virginia, the current data-center champ in the U.S., boasted a data-center market with 6,315 megawatts of capacity at the end of 2025, the report says. That compares with 2,423 megawatts in Dallas-Fort Worth, 1,700 megawatts in the Austin-San Antonio corridor, 200 megawatts in West Texas, and 164 megawatts in Houston.

Fervo taps into its hottest-ever geothermal reservoir

heat record

Things are heating up at Houston-based geothermal power company Fervo Energy.

Fervo recently drilled its hottest well so far at a new geothermal site in western Utah. Fewer than 11 days of drilling more than 11,000 feet deep at Project Blanford showed temperatures above 555 degrees Fahrenheit, which exceeds requirements for commercial viability. Fervo used proprietary AI-driven analytics for the test.

Hotter geothermal reservoirs produce more energy and improve what’s known as energy conversion efficiency, which is the ratio of useful energy output to total energy input.

“Fervo’s exploration strategy has always been underpinned by the seamless integration of cutting-edge data acquisition and advanced analytics,” Jack Norbeck, Fervo’s co-founder and chief technology officer, said in a news release. “This latest ultra-high temperature discovery highlights our team’s ability to detect and develop EGS sweet spots using AI-enhanced geophysical techniques.”

Fervo says an independent review confirms the site’s multigigawatt potential.

The company has increasingly tapped into hotter and hotter geothermal reservoirs, going from 365 degrees at Project Red to 400 degrees at Cape Station and now more than 555 degrees at Blanford.

The new site expands Fervo’s geologic footprint. The Blanford reservoir consists of sedimentary formations such as sandstones, claystones and carbonates, which can be drilled more easily and cost-effectively than more commonly targeted granite formations.

Fervo ranks among the top-funded startups in the Houston area. Since its founding in 2017, the company has raised about $1.5 billion. In January, Fervo filed for an IPO that would value the company at $2 billion to $3 billion, according to Axios Pro.
