Spring-based private equity firm Arroyo Investors has teamed up with ONCEnergy, a Portland, Oregon-based developer of clean energy projects, to buy a 60-megawatt wind farm southeast of Amarillo.

Skyline Renewables, which acquired the site, known as the Whirlwind Energy Center, in 2018, was the seller. The purchase price wasn’t disclosed.

Whirlwind Energy Center, located in Floyd County, West Texas, comprises 26 utility-scale wind turbines. The wind farm, built in 2007, supplies power to Austin Energy.

“The acquisition reflects our focus on value-driven investments with strong counterparties, a solid operating track record, and clear relevance to markets with growing capacity needs,” Brandon Wax, a partner at Arroyo, said in a press release. “Partnering with ONCEnergy allows us to leverage deep operational expertise while expanding our investment footprint in the market.”

Arroyo focuses on energy infrastructure investments in the Americas. Its portfolio includes Spring-based Seaside LNG, which produces liquefied natural gas and LNG transportation services.

Last year, Arroyo closed an investment fund with more than $1 billion in total equity commitments.

Since its launch in 2003, Arroyo has “remained committed to investing in high-quality assets, creating value and positioning assets for exit within our expected hold period,” founding partner Chuck Jordan said in 2022.

Houston industrial decarbonization-focused PE firm scores $725M to launch new business unit

this just in

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 PE firm acquires nuclear infrastructure company

M&A move

A Houston-based private equity firm has made a strategic acquisition.

Pelican Energy has acquired Container Technologies Industries from a group of private shareholders. CTI is a manufacturer of containment solutions for the nuclear industry and a certified HUBZone small-business whose customers include the U.S. Department of Energy, the U.S. Department of Defense and the commercial-nuclear space. Pelican makes investments in energy equipment and serves oil and gas companies and those in the nuclear sectors.

Pelican also named Danielle Castley as president of CTI. Castley has a PhD in material science with a background in radiation shielding material. She comes with over 10 years of experience in the nuclear industry. In addition to the majority buyout of legacy shareholders, Pelican will invest growth capital into business to expand capacity.

"CTI is a great company with a 20+ year track record of expansion,” Mike Scott, the founding partner of Pelican, says in a news release. “The company's highly-experienced team has a reputation of delivering the highest quality containment solutions, including specialty products and industry-standard containers. The business is well positioned to deliver products for growing customer demand."

The Houston company will now work closely with CTI’s homebase in Helenwood, Tennessee.

“We are excited to continue serving the Department of Energy and the thriving commercial nuclear industry,” Castley says in a news release. “I also look forward to leading CTI to innovate in manufacturing to address the emerging needs of advanced reactors.

"CTI will also expand our production capabilities to support Governor Lee's intent of establishing Tennessee as the leader of America's nuclear supply chain," she continues. "CTI is located in Helenwood, an economic development zone, where CTI will be actively recruiting to employ and train the next generation nuclear manufacturing workforce."

Houston chemical company divests new tech arm to PE

M&A moves

A New Orleans-based private equity firm has announced the acquisition of a Houston chemical company's technology business unit, the business announced today.

Black Bay Energy Capital acquired a portion of Merichem Company’s business — including its Merichem Process Technologies and Merichem Catalyst Products, which will collectively be renamed Merichem Technologies. Merichem's caustic services business, which handles spent caustic for beneficial reuse, will be maintained by the company.

Cyndie Fredrick has been promoted to CEO of Merichem Technologies. She previously served as Merichem's senior vice president and general manager of Merichem Process Technologies. She's joined by CFO Rene Campos, Senior Vice President of Technology Jeff Gomach, and Senior Vice President of Catalysts William Rouleau, who are all former managers within Merichem.

“The Merichem Technologies team has successfully deployed highly engineered and patented technologies, chemical catalysts, and mechanical solutions to various end markets including liquified natural gas, midstream oil and gas, refining of traditional crude and renewable feedstocks, biogas/landfill/RNG production, geothermal energy production, and chemical manufacturing," Fredrick says in a news release. "Merichem Company has been a fantastic steward of this business for decades, and the entire Merichem Technologies team is excited about our new partnership with Black Bay and the ability to pursue new avenues for growth.”

Additionally, Merichem Company's CEO Kendra Lee will join the Merichem Technologies board. Lee's grandfather founded the company in 1945, and she told EnergyCapital last year that she hopes to continue the legacy of the company, which designs and fabricates equipment for sulfur removal.

“Our reputation has always stood on the principles of proven performance, unsurpassed expertise, and an uncommon commitment to our customers," Lee says in the release. "This divesture is a major milestone for Merichem Company as we continue to execute on our strategic vision, further cementing our leadership position in caustic services.”

Black Bay focuses on the energy and specialty chemical sectors, but the Merichem Technologies acquisition brings a new sulfur-treating platform to the firm.

“Sulfur treatment is a critical path item across many industrial applications around the world. Hydrogen sulfide, mercaptans, carbon dioxide, and other related impurities must be dealt with to ensure environmental compliance, sustainable operations, and a saleable end product," Tom Ambrose, partner of Black Bay, says in the release.

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 chemical co. completes successful field trial of cleaner natural gas processing tech

successful trial

Houston-based Merichem Technologies has announced successful results from the field trial of its new hydrogen sulfide (H2S) removal technology in the Permian Basin.

The technology, known as ECOTREAT, removed more than 99 percent of hydrogen sulfide gas from natural gas streams, or “sour gas,” without producing solid waste during the month-long trial. It also showed sustained performance even when operating above the unit’s design capacity, according to a news release.

“The industry is continually seeking to reduce both the price and complexity of removing hydrogen sulfide from gas production, especially since oil production has shifted to increasingly sour sources, higher gas ratios, and higher water ratios,” Jeff Gomach, SVP, Merichem Technologies, said in a news release. “ECOTREAT met all its field trial objectives and provides a highly effective method for removing hydrogen sulfide to prevent equipment corrosion, ensure worker safety, meet environmental regulations, and maintain product quality for transport.

H2S found in natural gas can turn the gas toxic or hazardous and lead to corrosion in pipelines and processing equipment. However, standard H2S removal technologies create high levels of solid waste. ECOTREAT resolves many of those issues by using an aqueous-phase proprietary catalytic process that converts H2S into dissolved thiosulfate.

Next, Merichem says it plans to move the technology out of the pilot stage to full-scale commercialization.

Merichem, an 80-plus-year-old company, initially launched as a soap and industrial cleaning company. It eventually transitioned to focus on energy technology.

In 2024, Black Bay Energy acquired a portion of Merichem Process Technologies and Merichem Catalyst Products, which would become Merichem Technologies.

Cemvita reaches breakthrough in sustainable fuel feedstock production

clean fuels

Houston-based biotech company Cemvita announced that it recently reached a critical milestone in the development of its FermOil product, which can be used to create Sustainable Aviation Fuel (SAF) and other renewable fuels at industrial scale.

The company shared in a news release that it completed a 75,000-liter industrial fermentation run at Belgium's Bio Base Europe Pilot Plant.

The campaign achieved target technical metrics for the production of FermOil, Cemvita’s renewable natural oil (RNO). FermOil is produced from industrial crude glycerin, an industrial byproduct, as opposed to traditional sugar-based feedstocks used in many bio-oil fermentation processes. It's designed to be a drop-in feedstock for creating SAFs.

Cemvita had previously advanced its FermOil production process through multiple scale-up stages before successfully reaching the 75,000-liter demonstration campaign, according to the company.

“This is not just a fermentation milestone,” Moji Karimi, CEO at Cemvita, said in the release. “It is a blueprint for how existing industrial infrastructure can evolve into circular bioeconomy infrastructure. Every biodiesel plant generating crude glycerin is a potential platform for renewable natural oil production.”

The milestone also supports the deployment of Cemvita’s industrial biomanufacturing platform, FermWorks, which integrates with existing energy and industrial infrastructure to turn waste carbon streams into SAFs and other materials. According to the release, Cemvita plans to move forward with commercial deployment discussions with partners in Brazil, Europe and in the UK. Cemvita already has a partnership with the Brazilian sustainable research institution REMA.

“We are proud to support innovative companies like Cemvita in scaling breakthrough industrial biotechnology solutions,” Hendrik Waegeman, head of business operations at Bio Base Europe Pilot Plant, added in the release. “Successfully operating at the 75,000-liter scale using a feedstock such as crude glycerin highlights both the maturity of the technology and the quality of the scale-up execution achieved by the Cemvita team.”
