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.
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.
Corrosion is not something most people think about, but for Houston's industrial backbone pipelines, refineries, chemical plants, and water infrastructure, it is a silent and costly threat. Replacing damaged steel and overusing chemicals adds hundreds of millions of tons of carbon emissions every year. Despite the scale of the problem, corrosion detection has barely changed in decades.
In a recent episode of the Energy Tech Startups Podcast, Anwar Sadek, founder and CEO of Corrolytics, explained why the traditional approach is not working and how his team is delivering real-time visibility into one of the most overlooked challenges in the energy transition.
From Lab Insight to Industrial Breakthrough
Anwar began as a researcher studying how metals degrade and how microbes accelerate corrosion. He quickly noticed a major gap. Companies could detect the presence of microorganisms, but they could not tell whether those microbes were actually causing corrosion or how quickly the damage was happening. Most tests required shipping samples to a lab and waiting months for results, long after conditions inside the asset had changed.
That gap inspired Corrolytics' breakthrough. The company developed a portable, real-time electrochemical test that measures microbial corrosion activity directly from fluid samples. No invasive probes. No complex lab work. Just the immediate data operators can act on.
“It is like switching from film to digital photography,” Anwar says. “What used to take months now takes a couple of hours.”
Why Corrosion Matters in Houston's Energy Transition
Houston's energy transition is a blend of innovation and practicality. While the world builds new low-carbon systems, the region still depends on existing industrial infrastructure. Keeping those assets safe, efficient, and emission-conscious is essential.
This is where Corrolytics fits in. Every leak prevented, every pipeline protected, and every unnecessary gallon of biocide avoided reduces emissions and improves operational safety. The company is already seeing interest across oil and gas, petrochemicals, water and wastewater treatment, HVAC, industrial cooling, and biofuels. If fluids move through metal, microbial corrosion can occur, and Corrolytics can detect it.
Because microbes evolve quickly, slow testing methods simply cannot keep up. “By the time a company gets lab results, the environment has changed completely,” Anwar explains. “You cannot manage what you cannot measure.”
A Scientist Steps Into the CEO Role
Anwar did not plan to become a CEO. But through the National Science Foundation's ICorps program, he interviewed more than 300 industry stakeholders. Over 95 percent cited microbial corrosion as a major issue with no effective tool to address it. That validation pushed him to transform his research into a product.
Since then, Corrolytics has moved from prototype to real-world pilots in Brazil and Houston, with early partners already using the technology and some preparing to invest. Along the way, Anwar learned to lead teams, speak the language of industry, and guide the company through challenges. “When things go wrong, and they do, it is the CEO's job to steady the team,” he says.
Why Houston
Relocating to Houston accelerated everything. Customers, partners, advisors, and manufacturing talent are all here. For industrial and energy tech startups, Houston offers an ecosystem built for scale.
What's Next
Corrolytics is preparing for broader pilots, commercial partnerships, and team growth as it continues its fundraising efforts. For anyone focused on asset integrity, emissions reduction, or industrial innovation, this is a company to watch.
