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.

4 Houston energy companies named best places to work by U.S. News

Where to Work

Nearly a dozen public and private Houston-based companies have been hailed among the best places to work in 2025 by U.S. News and World Report, with four from the energy sector.

The annual "U.S. News Best Companies to Work For" report examines thousands of publicly-traded companies around the world to determine the best employers based on six metrics including work-life balance and flexibility; quality of pay and benefits; job and company stability; career opportunities and professional development; and more. The companies were not ranked, but included based on reader surveys and publicly available data about each workplace.

New for the 2025-2026 ratings, U.S. News expanded its methodology to include privately owned companies and companies with internship opportunities for recent graduates and new, current, and prospective students. Companies were also grouped into job-specific and industry-specific lists, and the publication also added a new list highlighting "employers that are particularly friendly to employees who are also caregivers in their personal lives."

U.S. News included seven publicly-traded companies and four privately owned companies in Houston on the lists.

Houston-based energy companies on the list

It may not come as a surprise that oil and gas corporation Chevron landed at the top of the list of top public employers in the Energy Capital of the World. The energy giant currently employs more than 45,000 people, earns $193.47 billion in annual revenue, and has a market cap of $238.74 billion. The company earned high ratings by U.S. News for its job stability, "belongingness," and quality of pay.

Chevron also appeared in U.S. News' industry-specific "Best in Energy and Resources" list, the "Best Companies in the South" list, and the "Best for Internships" list.

Chevron is joined by three other Houston energy leaders:

Calpine – Best in Energy and Resources; Best Companies (overall)
ConocoPhillips – Best in Energy and Resources; Best Companies (overall); Best in Caregiving; Best Companies in the South
Occidental – Best in Energy and Resources; Best Companies (overall); Best Companies in the South

Other top companies to work for in Houston are:

American Bureau of Shipping (ABS) — Best in Engineering and Construction; Best Companies (overall)
Hines – Best in Real Estate and Facilities Management; Best Companies (overall)
Insperity, Kingwood – Best in Healthcare and Research; Best Companies (overall); Best in Caregiving; Best Companies in the South
KBR – Best in Engineering and Construction; Best Companies (overall); Best Companies in the South
Men's Warehouse – Best in Consumer Products; Best Companies (overall)
PROS – Best in Information Technology; Best Companies (overall); Best Companies in the South
Skyward Specialty Insurance – Best in Finance and Insurance; Best Companies (overall); Best Companies in the South

"'Best' is a subjective term relative to career satisfaction, and many aspects factor into someone’s decision to apply for a job with any given company," U.S. News said. "But some universally desired factors can contribute to a good workplace, such as quality pay, good work-life balance, and opportunities for professional development and advancement

In all, 30 employers headquartered in the Lone Star State made it onto U.S. News' 2025-2026 "Best Places to Work For" lists. Houston and the Dallas-Fort Worth metro area tied for the most employers make the list, at 11 companies each. Diamondback Energy in Midland was the only company from West Texas to make it on the list for the second year in a row.

Exxon expands CO2 storage network with Calpine agreement

power deal

ExxonMobil Corp. has agreed to transport and permanently store up to 2 million metric tons per year of CO2 from Calpine Corp.’s Baytown Energy Center.

The strategic agreement is part of Calpine’s Baytown Carbon Capture and Storage (CCS) Project, which is designed to capture the energy center’s CO2 emissions and enable the supply of low-carbon electricity. It’s also in line with Exxon’s broader strategy to expand its CCS infrastructure along the Gulf Coast.

“Calpine is excited to partner with ExxonMobil to achieve this important project milestone,” Caleb Stephenson, Calpine Executive Vice President, said in a news release. “As the largest U.S. generator of electricity from natural gas, we understand that the nation’s gas fleet will remain the backbone of the grid for decades to come. We believe CCS is an actionable and cost-effective way to meet customers' demand for reliable power and alleviate concerns about the indisputable long-term need for gas-fired facilities. Low-cost natural gas along with carbon capture technology and widespread geologic storage resources can bolster U.S. energy, natural gas use, jobs, and export strength.”

The Baytown CCS Project is expected to produce about 500 megawatts of low-carbon electricity, which Calpine said is enough to power more than 500,000 homes. It can also provide steam for nearby industrial purposes.

The project anticipates creating construction and other full-time jobs, with engineering, permitting, and other development activities coming soon.

"We’re thrilled to work with Calpine on this project that supports American energy security, enhances industrial competitiveness and leverages America’s abundant low-cost natural gas resources," Barry Engle, President of ExxonMobil Low Carbon Solutions, said in a news release. “This agreement underscores the growing confidence our customers across diverse sectors—including steel, fertilizer, industrial gases, natural gas processing, and now power generation—have in our unique end-to-end CCS system.”

This is ExxonMobil’s sixth CCS customer, bringing the company's total amount of CO2 under contract to approximately 16 million tons a year, according to the company. The CO2 from Calpine’s facility will tie into ExxonMobil’s CO2 pipeline system on the Gulf Coast.

big deal

Baltimore-based nuclear power company Constellation Energy Corp. and Houston-based Calpine Corp. have entered into an agreement where Constellation will acquire Calpine in a cash and stock transaction with an overall net purchase price of $26.6 billion.

The companies say the agreement has the potential to create America’s “largest clean energy provider,” with what is reported to be the largest fleet of U.S. power stations servicing about 2.5 million customers.

“This is an incredible opportunity to bring together top tier generation fleets, leading retail customer businesses and the best people in our industry to help drive a stronger American economy for a cleaner, healthier and more sustainable future,” Andrew Novotny, president and CEO of Calpine, said in a news release.

Calpine is the largest U.S. producer of energy from low-emission natural gas generation and oversees the largest geothermal generation operation in the U.S. Last year it announced plans to build the Baytown Carbon Capture and Storage Project (Baytown CCS Project), a first-of-its-kind carbon capture demonstration facility, as part of a cost-sharing agreement with the U.S. Department of Energy.

Constellation is considered the top clean energy producer in the U.S., which provides 10 percent of the country’s emissions-free energy. The deal will add to Constellation’s already diverse portfolio of zero- and low-emission sources, including nuclear, natural gas, geothermal, hydro, wind, solar, cogeneration and battery storage.

“Both companies have been at the forefront of America’s transition to cleaner, more reliable and secure energy, and those shared values will guide us as we pursue investments in new and existing clean technologies to meet rising demand,” Joe Dominguez, president and CEO of Constellation, said the release. “What makes this combination even more special is it brings together two world-class teams, with the most talented women and men in the industry, who share a noble passion for safety, sustainability, operational excellence and helping America’s families, businesses and communities thrive and grow. We look forward to welcoming the Calpine team upon closing of this transaction.”

Constellation also announced that it will invest in adding more zero-emission energy to the grid to create “the most reliable generation portfolio in the U.S.” It plans to explore new advanced nuclear projects, invest in renewables and increase the output of existing nuclear plants.

“Together, we will be better positioned to bring accelerated investment in everything from zero-emission nuclear energy to battery storage that will power our economy in a way that puts people and our environment first,” Novotny said in a news release. “It’s a win for every American family and business in our newly combined footprint that wants clean and reliable energy. ECP’s commitment to these goals over the last seven years was critical to the progress we have made as a company and to laying a foundation for future growth.”

Carbon capture and storage

The first full-scale implementation of carbon capture and storage technology at a natural gas combined cycle power plant in the U.S. is coming to Baytown.

Houston power company Calpine announced plans to build the Baytown Carbon Capture and Storage Project (Baytown CCS Project), which is a carbon capture demonstration facility that aims to capture carbon dioxide from the Baytown Energy Center (BEC). The BEC is a natural gas combined-cycle power plant in Baytown.

The Department of Energy recently announced that it will share in the cost of up to $270 million on the Baytown project. The DOE revealed more details on the project on its website.

The project aims to utilize Shell’s CANSOLV point-source technology to capture up to 2 million metric tons of CO2 per year, which is equivalent to the annual emissions of nearly 450,000 gasoline-powered cars. In addition, the project plans to sequester the CO2 in saline storage sites on the Gulf Coast.

Evaluating the use of greywater cooling to minimize freshwater consumption by reusing wastewater, the project’s primary power and steam off-taker Covestro hopes to prove “technologies that showcase the benefits of decarbonized process heat and electricity in the industrial sector,” according to a news release.

In December of 2023, Calpine was selected by the Department of Energy's Office of Clean Energy Demonstrations for a cost-sharing agreement for a commercial-scale carbon capture and storage project.

"This is a critical step towards decarbonizing Calpine’s facility, which is located on our Covestro Baytown site,” Demetri Zervoudis, Covestro head of operations for North America and Baytown site general manager, said in a previous news release. “Carbon capture and storage technology is an important tool for the chemical industry to reduce carbon emissions, and it is encouraging to see Calpine at the forefront of this transition.”

The Baytown Decarbonization Project was developed collaboratively with local stakeholders in East Houston. According to the company, the project has already incorporated community feedback into the project designs to reduce non-CO2 air pollutants and minimize the usage of freshwater. The company estimates creating 22-26 permanent jobs and 1,500,000 hours of construction jobs and has partnerships with minority-serving institutions.

“Carbon capture is an important technology for decarbonizing the electricity sector and the economy,” Thad Hill, CEO of Calpine Corp said in 2023 when the DOE decided to work with the CSS program. “Calpine is very grateful for the commitment and support for the project by our stakeholders.”

Earlier this month, a Houston power company was selected by the Department of Energy's Office of Clean Energy Demonstrations for a cost-sharing agreement for a commercial-scale carbon capture and storage project.

Calpine's Baytown Decarbonization project is projected to capture and store about two million metric tons of carbon dioxide each year. The Baytown Energy Center is an existing 896-megawatt natural gas combined heat and power facility, according to a news release, "that provides steam and power to the adjacent Covestro chemicals manufacturing facility as well as power to the Texas electric grid."

The project will add post-combustion carbon capture equipment that will reduce the emissions intensity of two of its three combustion turbines at a design capture rate of 95 percent. In addition to the Baytown project, the DOE also selected Calpine’s carbon capture project at its Sutter Energy Center in California.

“We are very pleased and honored that the DOE has recognized the quality of this project and the strength of Calpine’s CCS program,” Thad Hill, CEO of Calpine Corp., says in the release. “We are looking forward to working with the DOE to finalize the cost-sharing agreement and with our other stakeholders to advance the development of the Baytown Decarbonization Project. Carbon capture is an important technology for decarbonizing the electricity sector and the economy. Calpine is very grateful for the commitment and support for the project by our stakeholders.”

The Baytown Decarbonization Project is being developed collaboratively with local stakeholders in East Houston. In addition to expanding full-time job opportunities, Calpine will enhance workforce development programs, target procurement with diverse and small business enterprises, and work with local schools and other organizations.

"This is a critical step towards decarbonizing Calpine’s facility, which is located on our Covestro Baytown site,” Demetri Zervoudis, Covestro head of operations for North America and Baytown site general manager, says in the release. “Carbon capture and storage technology is an important tool for the chemical industry to reduce carbon emissions, and it is encouraging to see Calpine at the forefront of this transition.”

ExxonMobil secures approval for $5B East Texas carbon capture project

ccs expansion

Spring-based ExxonMobil has won approval from the Texas Railroad Commission for a $5 billion carbon capture and storage project in East Texas.

Dominic Genetti, senior vice president of CCS at ExxonMobil, told The Financial Times, which broke the news, that the Railroad Commission’s action is a “major milestone” that lets the company keep expanding along the Gulf Coast. In a 2-1 vote, commissioners authorized a carbon sequestration permit for the project.

“The Railroad Commission clearly recognizes the important role carbon capture and storage can play in meeting growing global demand for lower-carbon products while supporting new jobs and economic growth,” Genetti said.

The U.S. Environmental Protection Agency (EPA) approved ExxonMobil’s Rose CCS project last year.

The project will enable the company to inject about 53 metric tons of industrial customers’ carbon emissions into three underground wells it drilled in the Beaumont-Port Arthur area. Over a 13-year period, ExxonMobil plans to inject about 4 million metric tons per year into the Fleming and Upper Frio rock formations, according to Carbon Herald.

ExxonMobil says it owns the world’s first and largest CCS system, comprising 1,300 miles of CO2 pipeline and secure storage sites. Seventy percent of the pipelines are along the Gulf Coast.

The company ramped up its CCS business in 2023 with the $4.9 billion purchase of Denbury, which owned about 1,000 miles of CO2 pipelines.

“Our expertise, combined with Denbury’s talent and CO2 pipeline network, expands our low-carbon leadership and best positions us to meet the decarbonization needs of industrial customers while also reducing emissions in our own operations,” ExxonMobil Chairman and CEO Darren Woods said when the deal closed.

In January, Genetti wrote in a post on ExxonMobil’s website that the company is committed to CCS “for the long haul.”

“CCS is not new technology, but it’s flown relatively under the radar compared with the attention that production of hydrocarbons commands,” he wrote. “Now, as the world becomes more aware of the need to reduce emissions, CCS finally has a brighter spotlight and a broader runway to scale up.”

The company also announced this week that it has begun CCS operations at a direct reduced iron facility in Convent, Louisiana. The project will capture, transport and store up to 800,000 metric tons of CO2 per year, according to the company.

Houston’s power future: The role of energy efficiency and demand response

The View from HETI

In Houston, industrial expansion, advanced manufacturing, data centers, AI, electrification, and population growth are all increasing demand for power across the region. At the same time, the infrastructure needed to support that growth, from generation and transmission to distribution and storage, takes significant time and investment to plan and build.

This growing power demand creates a near-term challenge: how can the region support new investment while major grid projects are planned and built?

A new report from the Houston Energy Transition Initiative, “Role of Efficiency & Demand Response to Meet Near-Term Regional Power Demand”, examines how Houston can get more from the grid it has today. Its central finding: energy efficiency (EE) and demand response (DE) can create measurable grid “headroom” while new major infrastructure projects are being planned, financed, permitted and built.

Explore the key takeaways from the report:

Houston’s power challenge affects economic growth

Houston’s ability to attract industrial investment increasingly depends on reliable, affordable power. ERCOT and MISO Texas project major load growth through 2030 and 2035 from industrial development, data centers, AI, advanced manufacturing and electrification.

Efficiency and demand response can lower peak demand and help manage local grid constraints that could slow growth.

EE and DE are different tools, and Houston needs both

Energy efficiency creates lasting reductions in electricity use through equipment upgrades, building improvements and changes in operations. Demand response lets customers temporarily reduce or shift power use based on grid conditions, incentives or market signals.

Texas programs show measurable results

In 2024, Texas investor-owned utility programs delivered about 609 MW of evaluated demand reduction and 603 GWh of annual energy savings. The report puts the lifetime cost of saved energy at about $0.02 per kWh.
CenterPoint Energy accounted for more than 40% of ERCOT investor-owned utilities’ total demand reduction and energy savings. It achieved about 236 MW of peak demand reduction and 229 GWh of energy savings, above goals of 66 MW and 116 GWh.

Entergy Texas also achieved significantly more demand reduction and energy savings than its 2024 program year goals, with a reported 24 MW of peak demand reduction against a goal of 17 MW and 43 GWh of energy savings against a goal of 30 GWh.

Large power users can add flexibility

Data centers, industrial facilities and advanced manufacturers may be able to shift noncritical work, adjust cooling, use on-site resources or briefly cut consumption.

The report states that verified demand savings, flexible loads and behind-the-meter resilience could help reduce interconnection risk and support more cost-effective growth.

Technology can expand options

Storage, smart controls and energy management systems can work with efficiency and demand response. Smaller loads can also be combined across commercial buildings, multifamily developments and homes.

For Houston, these tools do not replace new generation, transmission, distribution or storage. They can help the region use existing infrastructure more effectively while new capacity is built, supporting reliable, affordable power and continued economic growth.
