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.

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.

Houston clean energy startup acquired by battery storage company FlexGen

m&a activity

A North Carolina company has acquired Houston-based Clean Energy Services, a provider of services for battery energy storage systems and utility-scale solar, for an undisclosed amount.

The buyer is Durham, North Carolina-based FlexGen Power Systems, a provider of battery energy storage software and services.

Clean Energy Services (CES), whose offices are at the Ion, will operate as a subsidiary of FlexGen. Existing CES customers will continue to receive services from CES without disruption or change, FlexGen says.

“Demand for reliable, high-performance power is accelerating, and customers need partners who can deliver at scale,” Kelcy Pegler, CEO of FlexGen, said in a news release. “The addition of CES strengthens our service platform and reinforces our leadership in energy storage technology.”

Ahmad Atwan and Constantine Triantafyllides co-founded CES in 2022. As a startup, CES had raised $8 million in venture capital, according to PitchBook.

“CES has achieved a market leadership position in battery storage services by focusing on reliable speed of service delivery and optimizing asset performance,” Atwan, the company’s CEO, added the release. “FlexGen and CES have been strong partners for years, and this transaction enables us to deliver more robust solutions across a complementary set of customers and markets.”

CES will continue to operate its remote operations center in Houston for over 1 gigawatt of solar assets and 4.5 gigawatt-hours of battery assets, while FlexGen will maintain its remote operations center in Durham.

Halliburton Labs names 4 new clean energy startups to incubator

green team

Four new companies have joined Halliburton Labs, the incubator for early-stage energy and climate startups run by Houston energy giant Halliburton.

Halliburton Labs provides the emerging companies with mentorship, industry connections, laboratory access and other resources as they work toward commercialization, according to a news release.

The four new members include:

  • Nandina REM, a Singapore-based company that delivers carbon fiber thermoplastics. It turns end-of-life assets into new, reliable, high-performance materials for the aviation, aerospace and defense industries in a fraction of the time of standard supply chains.
  • Noon Energy, a California-based company that delivers clean, reliable electricity with ultra-long duration energy storage. Its system uses solid oxide electrochemical cells and stores energy as abundant, flexible industrial gases.
  • Proof Energy, a Silicon Valley-based company developed by the Lawrence Berkeley National Laboratory that is commercializing next-generation metallic solid oxide fuel cell (M-SOFC) technology. Its system uses widely available fuels such as ethanol, methanol, ammonia, and natural gas as hydrogen carriers to enable lower-cost, low-emission commercial transportation, and also offers a zero-emission heating solution to preserve battery range in electric vehicles.
