O&G exec: Houston is where the future of energy is taking shape

Q&A

Earlier this month, a West Texas-based oilfield equipment provider announced that it was opening an office in the Ion Houston. It's all a part of the company's energy transition plan.

SCS Technologies, based in Big Spring, Texas, has a new strategy and innovation-focused office in the Ion, the company announced last week. The company, which provides CO2 capture measurement and methane vapor recovery equipment for the energy, industrial, and environmental sectors, also announced René Vandersalm as the new COO.

These are just the latest moves for the company as the world moves away from hydrocarbons and toward a greener future, CEO Cody Johnson tells EnergyCapital, explaining that he recognizes Houston has a role in the energy transition.

"This is a relay race – a race that has already started," he says. "Houston is the place where the baton will be handed off – it’s the place where the race is occurring. SCS Technologies is determined to be part of this solution dreamed of and planned in Houston and then executed in the Permian Basin, where we call home."

In an interview with EnergyCapital, Johnson weighs in on the new office and the future of his company.

EnergyCapital: How has SCS’s business evolved amid the energy transition?

Cody Johnson: SCS Technologies was founded to design and fabricate customized Lease Automated Custody Transfer units in the Permian Basin. These LACT units were used primarily to measure the quality and quantity of crude oil at all points of custody transfer. Essentially, SCS Technologies produced the premier "crude cash registers" for the Permian Basin.

As the oil and gas industry has adapted into the energy transition industry, our customers and the communities we operate in have a growing need for SCS Technologies to use our design and fabrication of measurement skids to measure the quality and quantity of CO₂ or to design and fabricate methane — and other vent gases — Vapor Recovery Units. SCS Technologies’ design and fabrication expertise in measurement skids, pump skids, and compression skids, coupled with our Permian Basin based training and fabrication campus, ideally positioned us to answer the call to fill the expertise and capacity gap.

EC: How are you preparing for the future of energy?

CJ: Society has been powered for the past 100 years or so by the management of hydrocarbon molecules. The essential tools for that have been and continue to be oil rigs, pipelines, and refineries in large part. This has given society many benefits but at a price to the environment that isn’t sustainable. Over the next 50 years, society will complete a transition away from managing hydrocarbon molecules and towards managing electrons. Those electrons are created by wind, solar, geothermal, or nuclear processes and travel down copper wires. Managing this transition that is already occurring and working together to do it in the near-term future of energy.

As we execute this transition over the next several decades from managing molecules to managing electrons to provide energy, molecule management companies must find ways to reach net zero emissions in their management practices. This means primarily capturing and managing methane vapors and capturing and sequestering CO₂. This is starting in 2023 in a meaningful way and needs to continue past 2030 and probably past 2050 to have any chance to meet the globally shared social goal to achieve net zero emissions by 2050 and stay below a maximum increase of 1.5 degrees C in global temperatures.

The clock is ticking, and we are behind. The largest molecule management infrastructure investment in history must happen for us to reach these goals. It's mission-critical as one of the three things we simply cannot fail at to achieve net zero by 2050. SCS Technologies is very focused on being an intentional part of the tremendous supply chain buildout to support the infrastructure buildout.

EC: How does the new office in the Ion support these plans?

CJ: SCS Technologies needs to collaborate with the brightest minds working on the energy transition challenges. To contribute meaningfully to the overall effort and to be the thought leader in the methane vapor recovery and CO₂ compression and measurement niche, we need to be at the heart of the energy transition collaboration community. That beating heart is the Ion in Houston.

EC: What role does your new COO, René Vandersalm, play in SCS evolving with the energy transition?

CJ: René is a proven executive in growing mission-critical design and fabrication capacity without sacrificing quality. René’s experience, capabilities, and global network will play a key role in our path forward.

EC: Based in West Texas, SCS has a growing presence in Houston. Why do you see Houston as a leader in the energy transition?

CJ: West Texas has an amazing group of oil and gas professionals and infrastructure. We are proud of that heritage and will always maintain our roots and foundation there. Houston has the only community of engineers, scientists, universities, companies, investors, and key professional service providers that can deliver on the buildout of the molecule management infrastructure required to buy the electron management infrastructure folks time to transition fully to green energy after 2050.

This is a relay race – a race that has already started. Houston is the place where the baton will be handed off – it’s the place where the race is occurring. SCS Technologies is determined to be part of this solution dreamed of and planned in Houston and then executed in the Permian Basin, where we call home.

Texas oilfield equipment provider opens Houston office, names new COO amid energy transition growth

major moves

Big changes are happening at a Texas oilfield equipment provider. In the span of a few weeks, the company named a new C-level executive and announced a new strategic office.

SCS Technologies, based in Big Spring, Texas, has opened a new office in the Ion, a 266,000-square-foot innovation hub in Midtown, to focus on strategy and innovation. SCS provides CO2 capture measurement and methane vapor recovery equipment for the energy, industrial, and environmental sectors.

“Embracing Houston's pivotal role in the energy transition, the Ion has swiftly become the epicenter of innovative collaborations. For SCS Technologies, this marks an exciting opportunity to align our capabilities and technology with a diverse consortium of organizations working toward ambitious carbon-neutral goals,” says Cody Johnson, CEO of SCS Technologies, in a news release. “Looking ahead, we are invigorated by the boundless possibilities at the Ion, envisioning groundbreaking solutions and technologies that will unfold there.”

On July 20, SCS announced René Vandersalm as COO. Johnson says in a July 20 statement that the appointment comes at a time when "energy and industrial sectors are undergoing a considerable transformation of their processes and infrastructure to align with carbon-neutral goals."

Vandersalm previously worked for over 20 years at Thermon Manufacturing leading the company's heating solutions. In his new role, he says he will work within SCS "to design and produce the innovative compression and measurement systems our customers need to achieve emissions goals."

“It’s an exciting time as energy and industrial companies strive towards sustainable operations, all while delivering the energy and products that customers worldwide rely on,” Vandersalm continues in the release. “I am both excited and honored to collaborate with the talented and motivated SCS Technologies team as we make a significant impact in this industry-wide transition.”

SCS is partnered with New Orleans-based Black Bay Energy Capital, an energy-focused private equity fund.

The Ion has seen a flurry of activity when it comes to energy tenants. In March, United Kingdom-based Carbon Clean, opened its US headquarters in the Ion as it expands nationally. In April, the Ion named several other new tenants, which included industrial software company Cognite, robotics tech provider Nauticus, and more. These companies join Chevron, which officially opened its new outpost in 2022 after being announced as a founding partner in 2020. ExxonMobil is also a founding partner.

Enbridge activates first solar power project in Texas

power on

Canadian energy company Enbridge Inc., whose gas transmission and midstream operations are based in Houston, has flipped the switch on its first solar power project in Texas.

The Orange Grove project, about 45 miles west of Corpus Christi, is now generating 130 megawatts of energy that feeds into the grid operated by the Electric Reliability Council of Texas (ERCOT). ERCOT supplies electricity to 90 percent of the state.

Orange Grove features 300,000 solar panels installed on more than 920 acres in Jim Wells County. Construction began in 2024.

Telecom giant AT&T has signed a long-term power purchase agreement with Enbridge to buy energy from Orange Grove at a fixed price. Rather than physically acquiring this power, though, AT&T will receive renewable energy certificates. One renewable energy certificate represents the consumption of one megawatt of grid power from renewable energy sources such as solar and wind.

“Orange Grove is a key part of our commitment to develop, construct, and operate onshore renewable projects across North America,” Matthew Akman, executive vice president of corporate strategy and president of renewable power at Enbridge, said in 2024.

Orange Grove isn’t Enbridge’s only Texas project. Enbridge owns the 110-megawatt Keechi wind farm in Jacksboro, about 60 miles northwest of Fort Worth, and the 249.1-megawatt Chapman Ranch wind farm near Corpus Christi, along with a majority stake in the 203.3-megatt Magic Valley I wind farm near Harlingen. The company’s 815-megawatt Sequoia solar project, east of Abilene, is scheduled to go online in early 2026. Enbridge has signed long-term power purchase agreements with AT&T and Toyota North America for energy produced by Sequoia.

During a recent earnings call, Enbridge President and CEO Greg Ebel said that given the “unprecedented demand for power generation across North America,” driven largely by explosive growth in the data center sector, the company expects to unveil more renewable energy projects.

“The policy landscape for renewables is dynamic,” Ebel said, “but we think we are well-positioned with our portfolio of late-stage (projects).”

Houston's Rhythm Energy expands nationally with clean power acquisition

power deal

Houston-based Rhythm Energy Inc. has acquired Inspire Clean Energy for an undisclosed amount. The deal allows Rhythm to immediately scale outside of Texas and into the Northeast, Midwest and mid-Atlantic regions, according to a release from the company.

Inspire offers subscription-based renewable electricity plans to customers in Pennsylvania, New York, New Jersey, Massachusetts, Ohio, Delaware, Illinois, Maryland, and Washington, D.C. By combining forces, Rhythm will now be one of the largest independent green-energy retailers in the country.

“Adding Inspire to the Rhythm family gives us the geographic reach to serve millions of new customers with the highly rated customer experience Texans already enjoy,” PJ Popovic, CEO of Rhythm, said in the release. “Together we become one of the largest independent green-energy retailers in the country and can roll out innovations like our PowerShift Time-of-Use plan and device-enabled demand-response programs that put customers fully in control of their energy costs.”

Rhythm was founded by Popovic in 2020 and offers 100 percent renewable energy plans using solar power, wind power and other renewable power sources.

In addition to scaling geographically, the acquisition will "(marry) Rhythm's data-driven technology with Inspire's successful subscription model." Rhythm also plans to upgrade its digital tools and provide more advanced services to help lower clean energy costs, according to the release.

Popovic spoke with EnergyCapital in 2023 about where he thinks renewables fit into Texas’s energy consumption. Read more here.

Fervo Energy lands $200 million in capital for new geothermal project

fresh funding

Houston-based Fervo Energy, a producer of geothermal power, has secured $205.6 million in capital to help finance its geothermal project in southern Utah.

The money will go toward the first and second phases of Cape Station, a geothermal energy plant being developed in Beaver County, Utah. Beaver County is roughly an equal distance between Salt Lake City and Las Vegas.

The $205.6 million in capital came from three sources:

$100 million in equity from Breakthrough Energy Catalyst, a Kirkland, Washington-based platform that invests in emissions-reducing projects.
$60 million addition to Fervo’s existing loan from Mercuria, a Swiss energy and commodities trader. The revolving loan now totals $100 million.
$45.6 million in additional bridge debt financing from XRL-ALC, an affiliate of Irvington, New York-based X-Caliber Rural Capital. X-Caliber is a USDA-approved lender. The initial bridge loan was $100 million.

The first phase of Cape Station will supply 100 megawatts of carbon-free electricity to the power grid starting next year. Another 400 megawatts of capacity is supposed to go online by 2028. Fervo has permission to expand Cape Station’s capacity to as much as 2 gigawatts. On an annual basis, 2 gigawatts can supply enough electricity to power about 1.4 million homes.

“These investments demonstrate what we’ve known all along: Fervo’s combination of technical excellence, commercial readiness, and market opportunity makes us a natural partner for serious energy capital. The confidence our investors have in Fervo and in the Cape asset affirms that next-generation geothermal is ready to play a defining role in America’s energy future,” David Ulrey, Fervo’s CFO, said in a news release.
