XGS Energy, a Houston-based developer of geothermal power systems, has added several energy industry veterans to its C-suite this summer.

The company named Al Vickers as its new chief operating officer earlier this month. Vickers will replace Ghazal Izadi in the role, as she moves into the chief growth officer position.

Vickers previously served as CEO of bp's U.S. Low Carbon Energy business and most recently was COO of Houston-based Grid United, which develops next-generation transmission infrastructure.

“I have spent my career developing, building, and operating large, complex energy infrastructure, and I am excited to work with XGS’s proven technology, which is ready to deliver clean, round-the-clock power at the scale the grid and customers need,” Vickers said in a news release. “XGS sits at the intersection of innovation, affordability, demand growth, responsible infrastructure development, and long-term energy resilience. I’m excited to roll up my sleeves and apply best practices from both oil and gas and infrastructure development to deliver gigawatt-scale geothermal projects.”

Kurt Fricker, who most recently held leadership roles at Hess Corporation, was also announced as XGS's new chief procurement officer.

The hires come shortly after XGS announced Richard Chong as its new chief financial officer in May.

Chong joins XGS from Houston-based power producer Calpine, where he most recently was vice president of finance. His work there included leading $2.25 billion in financing for Geysers, the world’s largest geothermal power complex.

Chong says XGS’ proven technology and the rising demand for clean power will help the company execute on its multi-gigawatt pipeline.

“I look forward to applying the experience I’ve built over two decades in energy finance to help XGS deliver clean, reliable power to customers and unlock the massive development opportunity ahead for next-generation geothermal,” Chong said in the release.

XGS’ first project is a 150-megawatt geothermal facility in New Mexico. It will supply around-the-clock electricity to the grid operated by Public Service Co. of New Mexico in support of Meta data centers.

XGS recently tapped Houston-based energy technology company Baker Hughes to provide engineering services for the New Mexico project.

XGS’ geothermal system uses thermally conductive materials to deliver affordable energy anywhere hot rock exists — without the need for water resources or specific geological conditions. This results in lower-risk projects, more site options, easier permitting and faster deployment.

Since 2023, XGS has raised nearly $57 million in venture capital.

XGS launched in 2008 in Palo Alto, California, as Geothermic Solution. In conjunction with its Series A round in 2023, the company rebranded to its current name. The company recently moved its headquarters to Houston, according to the Houston Business Journal.

Oxy officially announces CEO transition, names successor

new leader

Houston-based Occidental (Oxy) has officially announced its longtime CEO's retirement and her successor.

Oxy shared last week that Vicki Hollub will retire June 1. Reuters first reported Hollub's plan to retire in March, but a firm date had not been set. Hollub will remain on Oxy's board of directors.

Richard Jackson, who currently serves as Oxy's COO, will replace Hollub in the CEO role.

“It has been a privilege to lead Occidental and work alongside such a talented team for more than 40 years," Hollub shared in a news release. "Following the recently completed decade-long transformation of the company, we now have the best portfolio and the best technical expertise in Occidental’s history. With this strong foundation in place, a clear path forward and a leader like Richard, who has the experience and vision to elevate Occidental, now is the right time for this transition. “I look forward to supporting Richard and the Board through my continued role as a director.”

Hollub has held the top leadership position at Oxy since 2016 and has been with the energy giant for more than 40 years. Before being named CEO, she served as COO and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Hollub also played a key role in leading Oxy's future as a "carbon management company."

Jackson has been with Oxy since 2003. He has held numerous leadership positions, including president of U.S. onshore oil and gas, president of low carbon integrated technologies, general manager of the Permian Delaware Basin and enhanced oil recovery oil and gas, vice president of investor relations, and vice president of drilling Americas.

He was instrumental in launching Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others, according to the company. He also serves on the Oil and Gas Climate Initiative’s Climate Investment Board and the American Petroleum Institute’s Upstream Committee. He holds a bachelor's degree in petroleum engineering from Texas A&M University.

Jackson was named COO of Oxy in October 2025. In his new role as CEO, he will also join the board of directors, effective June 1.

“I am grateful to be appointed President and CEO of Occidental and excited about the opportunity to execute from the strong position and capabilities that we built under Vicki’s leadership,” Jackson added in the release. “It means a lot to me personally to be a part of our Occidental team. I am committed to delivering value from our significant and high-quality resource base. We have a tremendous opportunity to focus on organic improvement and execution to deliver meaningful value for our employees, shareholders and partners.”

“Promethean has built a differentiated platform for managing and retiring late-life assets safely, efficiently, and responsibly,” Fear said in a news release. “The industry is facing a structural shift as decommissioning moves to the forefront, and the opportunity to combine operational excellence, disciplined project delivery, and innovative commercial models is incredibly compelling."

Promethean has developed an environmentally sustainable, integrated model for late-life asset management and offshore well decommissioning. Fear will oversee day-to-day operations at Promethean and the execution of this integrated operator-service model as the company looks to scale and expand to new markets.

“Martyn is a proven leader with a deep operational track record and a passion for building high-performance, safety-first organizations,” Aditya Singh, Promethean's CEO, added in the release. “As Promethean enters its next phase—scaling our integrated operator-service model and delivering first-time-right decommissioning at pace—his experience in transforming complex asset portfolios and leading global teams makes him the ideal COO to drive operational execution while we continue to advance our strategic vision.”

Last May, the company successfully decommissioned offshore orphaned wells in the Matagorda Island lease area. In November, it also announced that it had completed a multi-client project to safely plug and abandon an orphaned well on a storm-damaged platform in the South Timbalier lease area.

Both projects were based in the Gulf of Mexico, where Promethean is looking to grow.

ExxonMobil expands Gulf Coast CCS business with Louisiana deal

carbon contract

Spring-based energy powerhouse ExxonMobil has picked up another project in the carbon capture and storage (CCS) market.

Natural gas pipeline operator Williams Cos. has tapped ExxonMobil to transport and store up to one metric ton per year of CO2 from Williams’ natural gas collection and processing plant in southwest Louisiana’s Haynesville Shale.

Williams will transport natural gas via its Louisiana Energy Gateway pipeline, then process the natural gas and deliver it to the Gulf Coast for export as liquefied natural gas (LNG). The LNG will be used in power generation, residential and commercial heating, and industrial processes.

Williams recently agreed to acquire Momentum Midstream for up to $5.5 billion to expand Williams’ LNG presence in the Haynesville Shale. Haynesville is the country’s third-largest producer of natural gas.

Once the deal closes, Williams will own a $1.5 billion project in southwest Louisiana that will expand capacity of the Transco natural gas distribution system. The system serves power and LNG-export customers. Williams will also gain over 4,000 miles of pipeline and more than one million acres.

While Williams is based in Tulsa, Oklahoma, it has a significant presence in Houston. Last month, Green Street’s Real Estate Alert reported Williams bought the 64-story, 1.4 million-square-foot Williams Tower south of The Galleria from Invesco Real Estate for more than $300 million. The company will occupy about 360,000 square feet in the skyscraper for its Houston hub.

Williams employs about 800 people in Bayou City, including roughly 700 who work at Williams Tower, and plans to hire another 100 by the end of this year.

The Williams deal is ExxonMobil’s seventh CCS contract. ExxonMobil’s CCS portfolio supports LNG, lower-carbon-intensity steel, ammonia, natural gas processing, industrial gases and methanol.

ExxonMobil has established a “carbon superhighway” along the Gulf Coast to fuel its CCS business. The company owns and operates a more than 1,300-mile CO2 pipeline system, the largest in the U.S.

“Carbon capture is becoming an increasingly important part of industrial operations, but capture alone doesn’t solve the problem of high emissions,” says ExxonMobil. “What matters next is how CO2 is transported, used, and stored.”

ExxonMobil’s CCS initiatives are aimed at capturing a chunk of the rapidly growing CCS market in the U.S. Straits Research forecasts the market will grow from $5.66 billion this year to $13.56 billion by 2034.

“It’s not every day you get to witness the birth of a new American industry, but that’s exactly what’s happening right now at the U.S. Gulf Coast,” Dominic Genetti, senior vice president of CCS at ExxonMobil, wrote in an article published last year on the company’s website.

Fervo Energy, Mercury Fund leaders named first experts in residence for TEX-E

energy mentors

Two leading companies in Houston's clean energy scene have been named the Texas Exchange for Energy & Climate Entrepreneurship's first experts in residence.

TEX-E announced this month that Houston-based geothermal unicorn Fervo Energy and venture capital firm Mercury Fund have joined the nonprofit's new Expert-in-Residence partnership. The program aims to connect TEX-E Fellows with "the people and organizations shaping the future of energy and entrepreneurship."

The 2026 TEX-E Fellows were named in June and include 67 students from six Texas universities and the Massachusetts Institute of Technology. Nineteen are from Houston universities. See the full list here.

Through the Expert-in-Residence program, fellows will be able to network and work with:

"More than anything, students need the determination and creativity to step outside of their comfort zones and tackle problems that lack clear answers. At Fervo, we've consistently bet on young people who lack traditional 'hard skills' but are willing to embrace uncertainty and learn on the job. That open-mindedness will take students far," Jewett said in a prepared statement. Fervo named Jewett as COO in June.

TEX-E was founded in 2022 through partnerships with MIT Martin Trust Center for Entrepreneurship and Greentown Labs. It works with university students from six schools: Rice University, University of Houston, Prairie View A&M University, The University of Texas at Austin, Texas A&M University and MIT.

The organization named Houston venture capital and innovation leader Sandy Guitar as its new executive director last year. Guitar previously served as general partner and managing director at Houston-based VC firm HX Venture Fund and is co-founder of Weathergage Capital.

TEX-E is known for its student track within the Energy Venture Day and Pitch Competition at CERAWeek. It awarded $50,000 to student teams from the University of Texas and Rice University. Read more here.

BP to sell Houston’s Archaea Energy after $4.1 billion bet on biogas

RNG exit

Oil and gas conglomerate BP is unloading its Houston-based U.S. renewable natural gas business just four years after buying it.

The British company announced the planned sale of Archaea during its most recent earnings call but offered few details.

On the call, BP’s new CEO, Meg O’Neill, said her company had put Archaea on the market and already had attracted interest from potential buyers. BP acquired Houston-based Archaea Energy, the country’s largest producer of renewable natural gas (RNG), in 2022 for about $4.1 billion.

BP, whose North American headquarters is in Houston, is streamlining its portfolio. As such, O’Neill said Archaea represents a “capital intense” approach to biogas instead of the “capital light” approach BP now favors.

“If there’s somebody who sees an opportunity to create additional value, who will invest in that business, who will build on the foundation, because our team has made really good progress in improving the profitability of that business, then that will be a good outcome,” O’Neill told Wall Street analysts.

The proposed sale of Archaea is part of BP’s effort to sell about $20 billion in assets by the end of next year.

Archaea captures biogas, a natural byproduct of waste decomposition at landfills and dairy farms, and converts it into electricity or RNG. This process leads to cleaner air, less odor, and more sustainable energy than traditional fossil fuels.

Archaea was slated to be a cornerstone of BP’s plan to boost its biogas supply by roughly 600 percent to the equivalent of about 70,000 barrels of oil per day.

Bioenergy had been identified as one of bp’s five pillars of its multibillion-dollar energy transition initiative.

Another pillar: EV charging. Last month, BP agreed to sell its EV charging business in Austria to Switzerland’s Volenergy, along with 250 BP-branded stores and a fleet of business vehicles.

“By concentrating our capital on the assets and markets where BP can be most competitive and best serve customers, we are strengthening our balance sheet and creating a stronger downstream portfolio,” Richard Harding, interim executive vice president of downstream at BP, said of the Volenergy deal.
