Solaris Assets has completed its acquisition of the majority of Sunnova Energy International’s residential solar assets. Houston-based Sunnova filed for Chapter 11 bankruptcy this summer after piling up billions of dollars in debt.

Meanwhile, Sunnova founder and former CEO John Berger has launched a Houston-based home energy services startup, Otovo USA, which just received more than $4 million in seed funding.

Solaris now owns Sunnova’s residential solar services platform and its solar generation and storage portfolio, along with leases, loans and power purchase agreements. Sunnova’s operations are being shifted to SunStrong Management, an Austin-based asset manager for the renewable energy sector.

“By bringing together SunStrong’s asset management expertise with Sunnova’s nationally scaled customer base, we are creating a stronger, more capable leader in the solar industry,” Brendon Merkley, CEO of SunStrong, said in a news release. “Our priority is to maintain the highest levels of service for customers as we expand our footprint as a premier solar asset servicer.”

In June, Sunnova sold its new-home business to homebuilder Lennar for $15.2 million and sold certain assets to investment firm Atlas SP Partners for $15 million.

As of December, Sunnova’s debt totaled nearly $10.7 billion, Reuters reported. Sunnova faced numerous challenges in its quest to survive, including higher interest rates, the reduction of solar incentives in California, and a shakeup in federal subsidies for renewable energy.

Sunnova filed for Chapter 11 bankruptcy in June. A month later, a bankruptcy judge approved the court-supervised sale of Sunnova. Solaris’ acquisition of Sunnova closed Sept. 3.

As SunStrong absorbs the bulk of Sunnova’s assets, Berger — who quit in March as Sunnova’s CEO — has formed a new business. He’s now the founder and CEO of Otovo USA, a partner of European residential power company Otovo.

Otovo USA offers solar power systems, solar batteries, standby generators, EV chargers, electric-load managers, and other power generation and management systems. Otovo’s AI-supported offerings are now available in Texas; the company plans to expand nationwide.

Otovo USA raised its seed funding from the EIC Rose Rock Venture Fund, which invests in energy startups.

“Otovo USA is here to help the millions of Americans with home energy services that are fed up with the complexities of warranties, juggling multiple vendors, and long repair times,” Berger said. The startup, he added, “is bringing customers what they really need: reliable power and a single partner accountable for keeping it up and running. It’s your power, backed by ours.”

fresh funding

Houston-based Collide, a provider of generative artificial intelligence for the energy sector, has raised $5 million in seed funding led by Houston’s Mercury Fund.

Other investors in the seed round include Bryan Sheffield, founder of Austin-based Parsley Energy, which was acquired by Dallas-based Pioneer Natural Resources in 2021; Billy Quinn, founder and managing partner of Dallas-based private equity firm Pearl Energy Investments; and David Albin, co-founder and former managing partner of Dallas-based private equity firm NGP Capital Partners.

“(Collide) co-founders Collin McLelland and Chuck Yates bring a unique understanding of the oil and gas industry,” Blair Garrou, managing partner at Mercury, said in a news release. “Their backgrounds, combined with Collide’s proprietary knowledge base, create a significant and strategic moat for the platform.”

Collide, founded in 2022, says the funding will enable the company to accelerate the development of its GenAI platform. GenAI creates digital content such as images, videos, text, and music.

Originally launched by Houston media organization Digital Wildcatters as “a professional network and digital community for technical discussions and knowledge sharing,” the company says it will now shift its focus to rolling out its enterprise-level, AI-enabled solution.

Collide explains that its platform gathers and synthesizes data from trusted sources to deliver industry insights for oil and gas professionals. Unlike platforms such as OpenAI, Perplexity, and Microsoft Copilot, Collide’s platform “uniquely accesses a comprehensive, industry-specific knowledge base, including technical papers, internal processes, and a curated Q&A database tailored to energy professionals,” the company said.

Collide says its approximately 6,000 platform users span 122 countries.

Houston clean energy provider raises $10.8M series A

money moves

A tech-driven retail energy provider based in Houston has secured an oversubscribed series A round of funding.

Branch Energy raised a $10.8 million round led by climate-focused venture capital firm Prelude Ventures with co-investor Zero Infinity Partners, an infrastructure tech-focused firm. The fresh funding will go toward accelerating the company's battery management tech and build out the infrastructure of its field services.

A vertically integrated power provider, Branch Energy aims to provide customers with demand management software and battery storage systems to ensure long-term, stable, and clean energy at a lower cost than competitors.

“Our century-old grid design is not equipped for the complexity of today’s energy needs," Alex Ince-Cushman, Branch Energy co-founder and CEO, says in a news release. “Optimizing distributed energy assets in real-time will play an increasingly important role in managing the grid. We built Branch from the ground up as a technology company, allowing us to deliver value to customers in this new era of distributed energy by reducing costs while improving reliability."

The company chose Texas as its inaugural market based on the stress of the grid in the state, the company says in the release. Since 2021 when Branch Energy launched, it has signed up thousands of customers for its 100 percent clean energy service. The business proposition includes lowering customer's energy bills by 5 to 10 percent.

“The power grid, especially in Texas, requires distributed generation and flexible loads as basic economics drives deployment of more renewable resources,” Tim Woodward, managing partner at Prelude Ventures, adds. “Across the country, we are experiencing a major shift toward a decentralized and decarbonized grid. Branch Energy is bringing value to its customers through deployment of intelligent storage that lowers costs and improves reliability.”

Branch Energy, which is available now in some Texas regions, had previously raised $5.5 million in seed and pre-seed funding, per Crunchbase.

Houston energy workforce-focused startup raises $2.5M seed funding

cha-ching

With $2.5 million in fresh funding, Digital Wildcatters is on its way to keep empowering the evolving energy workforce.

Digital Wildcatters, a Houston company that's providing a community for the next generation of energy professionals, has closed its seed plus funding round at $2.5 million. The round by energy industry veteran Chuck Yates, who also hosts his podcast "Chuck Yates Needs a Job" on the Digital Wildcatters' podcast network.

"Our industry's survival depends on recruiting the next generation of energy workers. We must adapt to their digital, content-rich world, as we currently lag behind, like a VHS tape in a Netflix world. Digital Wildcatters is our path to modernization," Yates, based in Richmond, Texas, says in the news release.

Diamondback Energy and ProFrac also contributed to the round, which closed on December 1 and follows up on the company's $2 million seed round raised from angel investors in 2021.

The fresh funding will go toward further development and commercialization of Collide, an energy industry professional networking app, which launched this fall. The app aims to help advance and support the industry through professional development connection, job portal, and an AI-backed content search engine for industry information.

"Our mission is to empower the next generation of energy professionals to advance their careers and collaboratively address the global energy crisis," Collin McLelland, co-founder and CEO of Digital Wildcatters, says in the release. "We are incredibly grateful to have an investor base that not only believes in our vision but also supports our endeavor to craft innovative products that will redefine the future of the energy industry."

McLelland co-founded Digital Wildcatters with Jake Corley. The two started the Oil and Gas Startups podcast in 2019.

Houston company's sustainable spinoff launches with $8M in seed funding

vaulted with capital

Houston-based Advantek Waste Management Services, which specializes in deep-injection wells that minimize the impact of land, air, and water waste, has launched a carbon removal and storage company.

The spinoff, Vaulted Deep, is getting off the ground with $8 million in seed funding.

Vaulted diverts sludgy organic waste, such as agricultural and livestock waste, before it’s dumped in a landfill or waterway or simply left on land to decompose. It then captures and stores carbon emissions generated by the organic waste.

A study published earlier this year by Louisiana State University ecologist Brian Snyder estimated that organic waste generates five gigatons of carbon dioxide per year. A gigaton equals one billion metric tons.

Vaulted is already off to an impressive start. For one thing, the startup has raised an $8 million seed round led by New York City-based carbon removal fund Lowercarbon Capital. Other investors include Advantek and San Francisco-based climatech VC fund Earthshot Ventures.

In addition, Vaulted has already nailed down purchase commitments from Frontier, a marketplace for buyers and sellers of carbon removal credits. Ryan Orbuch, a partner at Lowercarbon, is one of Frontier’s strategic advisers.

“Vaulted is literally cleaning up the planet, scaling field-proven injection terminology to safely dispose of harmful wastes like biosolids while permanently storing away millions of tons of CO2,” Orbuch says in a Vaulted news release.

While injection sequestration sites often take years to gain permits and start operating, Vaulted already boasts two permitted sites that are up and running. Vaulted offers carbon removal for $300 per ton, compared with more than $500 per ton charged by some competitors.

Advantek founder Omar Abou-Sayed is switching from CEO to chairman of Advantek, which launched in 1999, and will serve as executive chairman of Vaulted. Julia Reichelstein, a former investor at San Francisco-based climatech VC fund Piva Capital, has been tapped as CEO of Vaulted.

“Unlike many carbon removal technologies still in R&D, Vaulted’s technology and sites can safely and permanently store carbon underground, at scale, today,” says Abou-Sayed. “The early removals we will deliver are pivotal to keeping the window open to hold our planet’s warming below 1.5 degrees Celsius.”

Energy startup Base Power raises $1 billion series C round

fresh funding

Austin-based startup Base Power, which offers battery-supported energy in the Houston area and other regions, has raised $1 billion in series C funding—making it one of the largest venture capital deals this year in the U.S.

VC firm Addition led the $1 billion round. All of Base Power’s existing major investors also participated, including Trust Ventures, Valor Equity Partners, Thrive Capital, Lightspeed Venture Partners, Andreessen Horowitz (a16z), Altimeter, StepStone Group, 137 Ventures, Terrain, Waybury Capital, and entrepreneur Elad Gil. New investors include Ribbit Capital, Google-backed CapitalG, Spark Capital, Bond, Lowercarbon Capital, Avenir Growth Capital, Glade Brook Capital Partners, Positive Sum and 1789 Capital Management.

Coupled with the new $1 billion round, Base Power has hauled in more than $1.27 billion in funding since it was founded in 2023.

Base Power supplies power to homeowners and the electric grid through a distributed storage network.

“The chance to reinvent our power system comes once in a generation,” Zach Dell, co-founder and CEO of Base Power, said in a news release. “The challenge ahead requires the best engineers and operators to solve it, and we’re scaling the team to make our abundant energy future a reality.”

Zach Dell is the son of Austin billionaire and Houston native Michael Dell, chairman and CEO of Round Rock-based Dell Technologies.

In less than two years, Base Power has developed more than 100 megawatt-hours of battery-enabled storage capacity. One megawatt-hour represents one hour of energy use at a rate of one million watts.

Base Power recently expanded its service to the city of Houston. It already was delivering energy to several other communities in the Houston area. To serve the Houston region, the startup has opened an office in Katy.

The startup also serves the Dallas-Fort Worth and Austin markets. At some point, Base Power plans to launch a nationwide expansion.

To meet current and future demand, Base Power is building its first energy storage and power electronics factory at the former downtown Austin site of the Austin American-Statesman’s printing presses.

“We’re building domestic manufacturing capacity for fixing the grid,” Justin Lopas, co-founder and chief operating officer of Base Power, added in the release. “The only way to add capacity to the grid is [by] physically deploying hardware, and we need to make that here in the U.S. ... This factory in Austin is our first, and we’re already planning for our second.”

ExxonMobil postpones $10B plastics manufacturing plant

plastics project postponed

Spring-based ExxonMobil is postponing development of a $10 billion plastics manufacturing plant along the Gulf Coast. Construction on the plant, to be located near Port Lavaca, was supposed to begin next year.

“Based on current market conditions, we are going to slow the pace of our development for the Coastal Plain Venture,” ExxonMobil confirmed in an emailed statement. “We’re confident in our growth strategy, and we remain interested in a potential project along the U.S. Gulf Coast and in other regions around the world. We’re maintaining good relationships with community leaders and contractors, so we are ready to reevaluate the project’s status when market conditions improve.”

According to Independent Commodity Intelligence Services, the Coastal Plain project was preliminary, and ExxonMobil had not yet announced its decision about building a plant for polyethylene production. Polyethylene, the world’s most common plastic, is used in a variety of products, such as bags, bottles, food containers, automotive components, medical tubes, IV bags, children’s toys and cutting boards.

The Coastal Plain postponement follows a judge’s ruling in August that invalidated a decision by Calhoun County ISD board members to negotiate tax breaks with ExxonMobil, according to Inside Climate News. The judge made the ruling in a case filed by environmental activist Diane Wilson and her nonprofit group, San Antonio Bay Estuarine Waterkeeper.

Wilson told Inside Climate News that she thought public opposition played a part in ExxonMobil postponing the Coastal Plain project.

“I think if everybody had just rolled over for them, if they got exactly what they wanted (tax breaks) and there wasn’t a big fight, there would be no delay,” Wilson said.

KBR shifts sustainability focus with planned spinoff

seeing green

Houston-based KBR, a provider of technology and engineering services for government and private-sector customers, is pursuing a tax-free spinoff of its Mission Technology Solutions business as a public company. Following the spinoff, KBR would remain a public company.

The new company, nicknamed SpinCo, would focus on technology and engineering services for the space and national security sectors. The scaled-down KBR, nicknamed RemainCo, would concentrate solely on sustainability technology and services designed to reduce carbon emissions and support energy transition efforts.

According to the company, RemainCo, or New KBR, will is positioned to serve the ammonia and syngas, chemical and petrochemicals, clean refining, and circular economy markets.

Stuart Bradie, chairman, president and CEO of KBR, said that from July 2024 to July 2025, the Mission Technology Solutions segment generated revenue of $5.8 billion. During the same period, the Sustainability Technology Solutions segment posted revenue of $3.7 billion.

KBR has forecast fiscal year 2025 revenue of $8.1 billion, up from $7.7 billion during the previous fiscal year. The company’s 2026 fiscal year starts in January.

In a news release, KBR said SpinCo and the restructured KBR would “deliver long-term profitable growth and value for customers, associates, and shareholders.”

“Our team has successfully built two leading businesses with the necessary scale and strong financial profile to enable us to take this next exciting step,” Bradie told Wall Street analysts.

Over the past decade, Bradie said, KBR has evolved into “a leading provider of differentiated, innovative, up-market science, technology, and engineering solutions with global scale, global reach, and global impact.” The spinoff would create two public companies that’ll “unlock the next phase of value creation,” he added.

Bradie will be chairman, president, and CEO of the newly configured KBR, while Mark Sopp, KBR’s executive vice president and chief financial officer, will transition to oversight of the Mission Technology Solutions spinoff. Effective Jan. 5, Shad Evans will succeed Sopp as CFO of KBR. He currently is KBR’s senior vice president of financial operations.

Bradie said an executive search firm has been hired to identify candidates for the CEO and CFO roles at SpinCo.

The spinoff is expected to be completed in mid- to late 2026.
