Houston-based Milestone Environmental Services announced this month that it has been acquired by affiliates of SK Capital Partners for an undisclosed amount.

The New York-based private investment firm, which specializes in the materials, ingredients, and life sciences sectors, now has a controlling stake of Milestone, which will continue to be led by its president and CEO Gabriel Rio.

Rio founded Milestone in 2014. The company is one of the largest independent providers of waste management services for the U.S. energy and industrial sectors. It focuses on permanent carbon sequestration services through its proprietary slurry injection process, which stores hydrocarbon waste over a mile underground.

The company's subsidiary, Milestone Carbon, is developing injection sites that permanently and securely sequester CO2. Earlier this month, Milestone Carbon announced that it has leased more that 22,000 acres of land in the Permian Basin for the permanent geologic sequestration of CO2 as part of the "sequestration hub" it is developing.

According to the company, once operating, the hub will help reduce emission related to natural gas processing, electricity generation and other industries. It's slated to be one of the first sequestration hubs in the basin.

"We founded Milestone to boldly advance sustainability in the energy industry and beyond," Rios says in a statement. "Our offerings enable companies to reduce their carbon footprint and enhance their ability to meet sustainability goals. Permanent, safe sequestration of carbon is an essential part of combating climate change, and Milestone has the strategy and capabilities to play a leading role in delivering solutions to multiple industries.”

According to a statement, Milestone has sequestered more than 2 million tons of CO2e through its injection process. The company has stated that it believes its sequestration hub will help attract new industries and technologies, hydrogen, low-carbon ammonia, and low-carbon power, to West Texas.

"We are highly impressed with the market-leading, sustainability-driven business that Gabriel and the Milestone management team have built," Jack Norris, a managing director of SK Capital, said in a statement. "It is well-positioned to further grow its core business in difficult-to-abate industries as environmental regulations become more stringent and Milestone’s customers are increasingly focused on meeting ambitious decarbonization targets. We are excited to partner with management to capture this growth opportunity as well as support its further progress towards becoming a leader in CCS and other related markets.”

Earlier this summer, Houston-based Occidental also got in on a carbon capture acquisition. Occidental says its all-cash acquisition of Carbon Engineering is set to close by the end of 2023. The Canada-based company focuses on direct carbon capture (DAC), which vacuums about 50 percent to 60 percent of the carbon dioxide from the air that passes through the system’s fans.

Oxy was granted $600 million from the U.S. Department of Energy to develop South Texas Direct Air Capture (DAC) Hub earlier this year. It’ll be located on about 106,000 leased acres within a Kleberg County site at the iconic King Ranch. The hub will comprise 30 individual DAC projects.

The U.S. Department of Energy also recently invested more than $10 million in funding for four DAC projects with Houston ties.

Oxy acquires carbon capture co. in $1.1B deal

betting on dac

In yet another bet on direct carbon capture (DAC), Houston-based Occidental has agreed to purchase a DAC technology company for $1.1 billion.

Occidental says its all-cash acquisition of Canada-based Carbon Engineering is set to close by the end of 2023. Carbon Engineering was founded in 2009.

Under the deal, Carbon Engineering would become a wholly owned subsidiary of Oxy Low Carbon Ventures, the investment arm of Occidental. Carbon Engineering employees will work with teams at Occidental and its low-carbon subsidiary, 1PointFive, on DAC technology. The company’s R&D and innovation units will remain in Squamish, British Columbia.

Occidental has been a key DAC partner of Carbon Engineering since 2019.

“We look forward to continuing our collaboration with the Carbon Engineering team, which has been a leader in pioneering and advancing DAC technology,” Vicki Hollub, president and CEO of Occidental, says in an August 15 news release. “Together, Occidental and Carbon Engineering can accelerate plans to globally deploy DAC technology at a climate-relevant scale and make DAC the preferred solution for businesses seeking to remove their hard-to-abate emissions.”

Billionaire Warren Buffett’s Berkshire Hathaway conglomerate owns about one-fourth of the shares of publicly traded Occidental.

In conjunction with Carbon Engineering, Occidental’s 1PointFive is building Stratos, the world’s largest DAC plant. The Ector County facility, scheduled to begin operating in mid-2025, is projected to extract up to 500,000 metric tons of carbon dioxide from the air each year. It’s anticipated that Stratos will employ more than 1,000 people during construction and up to 75 people once the plant is up and running.

Occidental and Carbon Engineering are adapting Stratos’ engineering and design features for a DAC plant to be built on a site at South Texas’ King Ranch. The South Texas DAC Hub, which is on track to create about 2,500 jobs, recently received a roughly $600 million grant from the U.S. Department of Energy (DOE).

1PointFive plans to open as many as 135 DAC facilities around the world by 2035, with the capacity to capture 100 million metric tons of carbon dioxide (CO2) per year.

DAC technology pulls carbon dioxide emissions from the atmosphere at any location and permanently stores the CO2 or uses it for other purposes. By contrast, carbon capture sucks carbon dioxide from the air near where emissions are generated and then permanently stores the CO2 or uses it for other purposes.

A DAC system vacuums about 50 percent to 60 percent of the carbon dioxide from the air that passes through the system’s fans.

DAC “is shaping up to be a key component of meeting net-zero emissions goals in the United States,” according to the National Renewable Energy Laboratory.

Rice, UH launch joint effort to accelerate plastics recycling solutions

plastics partnership

Institutes at two Houston universities are joining forces to help position the city as a global leader in plastics recycling innovation.

The Center for Energy Studies (CES) at Rice University’s Baker Institute for Public Policy and the University of Houston’s Energy Transition Institute (UH-ETI) have announced a strategic partnership that aims to develop real-world solutions for plastic recycling.

The universities will kick off the new initiative with the Annual Sustainability Summit: Innovations and Collaborations in Circularity & Supply Chain Resilience event April 22 at the Baker Institute.

“Houston sits at the center of the global plastics and petrochemical value chain, which makes it uniquely positioned to lead in circular solutions,” Rachel Meidl, deputy director of CES, said in a news release. “This partnership is about moving beyond theory and bringing together data, policy and industry insight to accelerate technologies and frameworks that can scale.”

The partnership—which was made official during CERAWeek—will integrate policy, economics, science and engineering. The universities will work to “share data, insights, networks and connections to advance global work in protecting the environment, economy and society,” according to a news release from Rice.

Initially, the universities will focus on evaluating scalable advanced recycling pathways, developing policy frameworks to improve plastics circularity, analyzing emerging technology and using industry stakeholders for deployment.

Plastics circularity aligns with Rice and UH’s energy transition efforts to advance a circular economy. UH's ETI recently published a white paper that analyzes how the U.S. currently handles plastics recycling and advocates for a new approach. Ramanan Krishnamoorti, author of the paper and vice president of energy and innovation at UH, said the partnership with Rice’s Baker Institute could help bring some of the ideas outlined in the paper to reality.

“Our research has shown that a uniform approach may be the best way for the U.S. to tackle plastic waste,” Krishnamoort said in a news release. “By partnering with Rice’s Baker Institute for Public Policy, we will be better positioned to deliver real-world solutions that advance a circular plastics economy.”

Fervo Energy adds former eBay CEO Meg Whitman, other leaders to board

power players

As it prepares for a highly anticipated IPO, Houston-based geothermal power provider Fervo Energy has added four heavyweights to its board of directors.

The most notable new board member is Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE, and former U.S. ambassador to Kenya. She joined the Fervo board as lead independent director.

One of the other high-profile new board members at Fervo is Jessica Uhl. She was chief financial officer of Shell from 2017 to 2022 and spent a little over a year as president of GE Vernova, a GE energy spinoff. She is a former board member of GE, Goldman Sachs and Shell. Today, Uhl advises investment firms on energy matters.

Another energy industry veteran, Trey Lowe, also joined the Fervo board. Lowe is senior vice president and chief technology officer at oil and gas producer Devon Energy, a Fervo investor that’s moving its headquarters from Oklahoma City to Houston. Before Devon, Lowe worked in the U.S. and Norway for Houston-based energy technology company SLB.

The fourth new director at Fervo is Robert Keehan, who spent 37 years at professional services firm PwC. He most recently was PwC’s chief global auditor and earlier was a partner in the firm’s energy practice.

Keehan and Uhl will serve as independent directors, which are non-executive governance and oversight roles, while Lowe is a non-independent director, which is a more hands-on role.

With the four new directors, Fervo has seven board members.

The arrival of the four new board members comes at a monumental time for Fervo, a provider of utility-scale geothermal energy:

“Energy markets are demanding dependable, carbon-free power at an unprecedented scale, and Fervo is uniquely positioned to supply it,” Tim Latimer, co-founder and CEO of Fervo, said in December.
