With over 70 years of experience, Nabors Industries has established itself as one of the largest land contract drilling companies in the world, as well as a provider of offshore platform rigs in the United States and international markets. But how is the company thinking of its next decades amid the energy transition?

Considering the role Nabors is playing in the future of energy is Houston-based Guillermo Sierra's job as vice president of energy transition. In a Q&A with EnergyCapital, he explains how the company envisions its future as an energy leader and what all that entails, including sourcing new technologies — sometimes from promising startups like Sage Geosystems.

EnergyCapital: Tell me about Nabors' commitment to the energy transition. What are your responsibilities leading this initiative?

Guillermo Sierra: Understanding that no single source today consistently delivers affordable, reliable and responsible energy, Nabors sees its future innovating solutions for hydrocarbons and clean energy while removing the tradeoffs between them. “Energy Without Compromise” is the vision guiding these efforts. Ultimately, we view three critical paths for the industry and ourselves to realize this:

Embrace energy innovation over energy exclusion. Too often the energy transition conversation is about excluding particular sources when we should be focused on solving challenges or overcoming limitations with technology. Oil and gas provide affordable and reliable energy but we must address emissions. Renewables are a greener solution but powering society, heavy industries, and hard-to-abate sectors requires sources that are clean, scalable, and baseload-seeking. For our part, we are lowering the carbon intensity of oil and gas operations with AI-based engine management software, fuel enhancers, highline power solutions, energy storage and forthcoming hydrogen injection systems while also investing in geothermal, concentrated solar power, alternative energy storage, emissions monitoring, hydrogen, and advanced materials, to make renewables a viable solution to decarbonize the industrial and energy industries.
Capitalize on strengths and adjacencies. Companies should seek opportunities to apply skillsets and competencies to advance other industries in the pursuit of a sustainable future. It is easy to see how our drilling expertise is valuable to the geothermal industry. Those companies need to drill wells and use technology that’s been developed by the oil and gas industry for decades to produce heat instead of hydrocarbons. Beyond the drill bit though, companies in the broader clean energy community see tremendous strategic value in partnering with Nabors. Our robotics, remote operations, software, automation, AI, manufacturing and engineering capabilities, global customer base of some of the world’s largest companies, worldwide vendor relationships and supply chain can be used to help startups grow and scale much more quickly.
Collaborate to accelerate progress. The proverb is if you want to go fast, go alone. If you want to go deep or go far, go together. Working together and leveraging collective strengths will help us solve some of the most meaningful challenges. There’s room for us all and we need to work together to achieve emissions goals.

EC: When considering a clean tech company, what are the top qualities driving your investment decisions? How did Sage Geosystems fit what you were looking for?

GS: Traditionally, renewables have stumbled some in the power business because they are intermittent and therefore not dispatchable or reliable baseload. There are also safety, supply chain, and environmental challenges to overcome with lithium-ion batteries and the lack of circularity of panels, blades, and other equipment. Additionally, to decarbonize industrial processes, you need clean and efficient sources of heat – which have largely been nonexistent. And the broader industrials complex needs green fuels, hydrogen and sustainable aviation fuel to eliminate their carbon footprint.

Therefore we believe the world needs clean, renewable, scalable, and baseload/dispatchable generation, and alternatives to today’s chemical-based energy storage. When we evaluate our investments, this is what we’re ultimately seeking.

Sage checks every one of these boxes. The company envisions producing renewable baseload power from geothermal and has novel solutions to energy storage. And unlike many geothermal companies, their approach is deployable today with off the shelf technologies.

EC: What role do you see enhanced geothermal playing in the energy transition?

GS: In my opinion, geothermal has been the gaping hole so to speak in net zero plans from companies and governments. Less than 1 percent of the earth is cooler than 1,000 degrees Celsius. Heat gradients needed are miles away while the sun is 93 million miles away. The oil and gas industry has spent decades perfecting how we drill safely and efficiently. We have near limitless energy beneath our feet and have the tools to tap it. Now we need the focus and capital of the broader energy complex.

EC: How big are your long-term aspirations for Nabors in regards to the energy transition?

GS: I believe the energy transition will represent one of the biggest reallocations of capital in human history. By some estimates, some $300 trillion is expected to spent. We want to be a leader. We want in early. We believe we have the skills, competencies, workforce, relationships, and scale to make a meaningful impact and we are taking action.

Texas battery startup Base Power hits $13B valuation with $1B raise

fresh funding

Base Power, an Austin-based residential power provider with a Houston office, has raised $1 billion in a Series D round, bringing the startup’s valuation to $13 billion.

Ribbit, Addition, Valor Equity Partners, and JPMorganChase’s Strategic Investment Group led the round, with participation from Altimeter, D1 Capital Partners, Sands Capital, Coatue, Layer Global, and Energy Impact Partners. Existing investors also added to the round, including Thrive Capital, a16z, Lightspeed, Trust Ventures, and CapitalG.

Base Power, which provides residential battery backup systems that automatically turn on during outages and sells electricity to homeowners, says the funding will go toward hiring more people and expanding nationally.

Since being founded in 2023, Base Power has raised more than $2.5 billion. Base Power’s factory in Austin is already manufacturing thousands of the batteries each month.

In conjunction with the funding announcement, the startup launched Base Core, a home battery designed to support the power grid. Today, Base Core is available to homeowners in certain parts of Texas and Illinois, including the Houston area.

Zach Dell, co-founder and CEO of Base Power, said in a news release that Base Core “installs in under an hour, switches over seamlessly, is built to handle extreme weather, and delivers extended outage protection at a price Americans can afford.”

Dell is the son of Austin tech billionaire Michael Dell, founder, chairman, and CEO of Round Rock-based Dell Technologies.

In only three years, Base Power has grown its battery fleet to a capacity of more than 500 megawatt-hours, expanded beyond Texas into Illinois, and forged partnerships with utilities such as Austin Energy, El Paso Electric, and CoServ.

Antonio Gracias, founder, CEO, and chief investment officer at Valor Equity Partners, says Base Power is executing on an “ambitious plan” to become America’s power company. The startup “has emerged as one of the fastest and most cost-effective ways to add capacity to the grid,” he says.

Base Power opened its offices in Katy, Texas, in October 2025 and expanded its service to the city of Houston around the same time. Read more here.

Houston subsea firm Zupt acquired in offshore tech deal

m&a activity

Houston-based Zupt LLC, a provider of advanced metrology, inspection, and engineering services for offshore energy and renewable projects, has been acquired by Columbus, Ohio-based Rosenxt Holding USA for an undisclosed amount.

Rosenxt says the deal, which closed July 21, represents another step in its long-term strategy to build a portfolio of technology and engineering capabilities for the subsea market in the energy sector.

“Our ambition has always been to think decades ahead,” Hermann Rosen, chairman of Switzerland-based Rosenxt Group, the parent company of Rosenxt Holding USA, said in a news release.

“The future of subsea and offshore industries will be shaped by intelligent technologies that fundamentally change how critical infrastructure is explored, installed, inspected and operated,” he added. “Zupt is another important building block in this vision.”

Rosenxt says offshore operators and installation contractors face pressure to execute subsea projects more efficiently amid workforce shortages, weather concerns, tougher safety standards, and rising capital and operating expenses.

“The offshore sector continues to embrace technologies that enhance data quality, reduce operational risk, and improve decision-making across the asset lifecycle,” Houston M&A attorney Amelia Zhang, who led law firm Norton Rose Fulbright’s representation of Zupt, added in the release.

Rosenxt provides services for the subsea market that combine sensing, robotics, AI, analytics and engineering. Zupt complements those services with offerings for operations, such as high-resolution 3D inspection, digital twin generation, and inspection and engineering technologies for subs.

Zupt President Keith Vickery founded the company in 2005.

Vickery says Zupt “has focused on solving some of the subsea industry’s most demanding marine construction and inspection challenges through innovative engineering, operational experience, and close collaboration with our customers.”

Mordor Intelligence estimates the value of the subsea market will climb from $19.75 billion this year to $25.03 billion in 2031. North America represents the largest segment of the global market.

Houston energy tech company Molecule makes gas operations acquisition

software acquisition

Houston-based energy trading risk management (ETRM) software company Molecule has announced the acquisition of Dallas-based Trilogy Energy Solutions.

Molecule CEO Patrick Smith called the deal a "defining moment" for the company, as it allows Molecule's platform to expand to include physical gas operations.

“For years, this industry has drawn the ETRM box too small, creating inefficient silos by treating trading and physical operations as separate budgets and separate problems, when the real cost lives in the handoffs between them," Smith said in a news release. "Trilogy’s domain expertise in physical gas operations closes that gap. Together, we can give producers, midstream operators, and trading desks something the market has been asking for: a single, integrated view from wellhead to trading desk, without the manual reconciliation, spreadsheet workarounds, and legacy handoffs that slow the industry down.”

Trilogy, founded in 2014, is a provider of cloud-based software for the day-to-day logistics of physical natural gas operations. The platform allows users—including producers, marketers, midstream companies, pipeline operators and others—to manage activities such as pipeline nominations, gas gathering operations and more. Thus far, Molecule's platform has focused on energy trading and managing financial and commercial activities.

Through the acquisition, the combined company will now offer a full-stack enabled ETRM and energy operating system. Users of both platforms can expect continuity of service, according to the companies.

“Molecule has always been about meeting trading teams where they actually work, focused on being fast, accurate, and deeply integrated into their day-to-day workflow,” Sameer Soleja, founder and president of Molecule, added in the release. “Bringing Trilogy into the Molecule family extends that mission from the trading desk into the physical operations of the gas business. The two platforms complement each other exceedingly well, and the combined product will be able to offer all-in-one capabilities that lead the ETRM market, both in its tech-forward nature, and in its depth.”

Molecule expects the combined platform to help users reduce manual month-end close work, cut costs, and improve data accuracy and decision-making.

Trilogy's Chief Product Officer Jeremy Frye will join the Molecule team, along with others from Trilogy.

“Trilogy has spent decades building the trust of companies across the physical natural gas industry by delivering software that stands up to the demands of physical gas operations... It’s a rare combination that brings the best of both worlds, and I’m energized about what our teams will build together,” Frye added in the release.

California-based Sundance Growth, an existing investor in Molecule, supported the acquisition. The software growth equity firm raised a $125 million debut fund in 2025 and focuses on B2B SaaS companies.

Sundance led Molecule's Series B round, which closed last summer for an undisclosed amount. At the time, Soleja said the funding would allow Molecule to "double down on product innovation, grow our team, and reach even more markets."
