NOV opens applications for unique energy tech startup pilot program in Houston

calling all innovators

Houston-based NOV is launching a new growth-stage startup accelerator focused on the upstream oil and gas industry.

NOV, a provider of oil and gas drilling and production operations equipment, has announced its new NOV Supernova Accelerator in collaboration with VentureBuilder, a consulting firm, investor, and accelerator program operator led by a group of Houston innovators.

Applications to the program are open online, and the deadline to apply is July 7. Specifically, NOV is looking for companies working on solutions in data management and analytics, operational efficiency, HSE monitoring, predictive maintenance, and digital twins.

The five-month program establishes a significant relationship between the 20 selected startups and NOV, beginning with paid pilot programs.

"This is not a traditional startup accelerator. This is often a first-client relationship to help disruptive startups refine product-market fit and creatively solve our pressing enterprise problems," reads the program's website.

Selected startups will have direct access to NOV's team and resources. The program will require companies to spend one week per month in person at NOV headquarters in Houston and will provide support surrounding several themes, including go-to-market strategy, pitch practice, and more.

“The NOV Supernova Accelerator offers a strategic approach where the company collaborates with startups in a vendor-client relationship to address specific business needs," says Billy Grandy, general partner of VentureBuilder.vc, in a statement. "Unlike mergers and acquisitions, the venture client model allows corporations like NOV to quickly test and implement new technologies without committing to an acquisition or risking significant investment.”

Short film focused on Houston entrepreneur, energy transition ecosystem releases online

dirty nasty people

In a new short film, a Houston energy entrepreneur sets the scene for the energy industry and showcases her passion for an equitable transition for the sector.

"Dirty Nasty People" originally premiered May 18 to the Houston community. Now, the NOV-produced film featuring Katie Mehnert and her company Ally Energy is available for viewing online.

The film, directed by Paul Dufilho, tells Mehnert's story, her passion for energy, and her career, which began at Enron, grew at Shell and BP, and took her to founding a company dedicated to diversity, equity, and inclusion in the space. Ally Energy, which was founded in 2014 as Pink Petro, is a community and talent platform for the evolving energy industry.

In the movie, Mehnert introduces the dual challenge the industry is facing — and how DEI is integral to solving it.

“On the one hand, we all need energy — affordable, reliable energy — to keep lives going,” she says in the film. “But we are harming the planet. And ourselves.

"It is complicated — this challenge is very complicated," she continues. "But it’s going to take collaboration, and diversity of thought — diversity of energy form. It’s going to take bringing people into the energy industry, into the fold, looking at this challenge in a different way — but it’s all about working together.”

Houston-based NOV Inc., an international oil and gas industry equipment and tech provider, backed the production of the film which was meant to showcase Ally, Mehnert, and the energy transition ecosystem locally.

"The energy workforce of the future will need to be as large and diverse as the technical solutions that will be needed to offset the effects of Climate Change," writes Dufilho on the website. "This project hopes to put a singular human focus on what is one of the largest issues of our day.

"There are already incredible people inside the industry doing the work of developing better energy solutions, and this project highlights just one of them," he continues. "However, the energy problems of the near future will require the perspectives and know-how of those who have not yet seen themselves as part of the solution. The outsider. The consumer. This project is for them."

Houston company wins contract to operate South Texas wind farm

wind deal

Houston-based Consolidated Asset Management Services (CAMS), which provides services for owners of energy infrastructure, has added the owner of a South Texas wind power project to its customer list.

The new customer, InfraRed Capital Partners, owns the 202-megawatt Mesteño Wind Project in the Rio Grande Valley. InfraRed bought the wind farm from Charlotte, North Carolina-based power provider Duke Energy in 2024. CAMS will provide asset management, remote operations, maintenance, compliance and IT services for the Mesteño project.

Mesteño began generating power in 2019. The wind farm is connected to the electric grid operated by the Energy Reliability Council of Texas (ERCOT).

With the addition of Mesteño, CAMS now manages wind energy projects with generation capacity of more than 2,500 megawatts.

Mesteño features one of the tallest wind turbine installations in the U.S., with towers reaching 590.5 feet. Located near Rio Grande City, the project produces enough clean energy to power about 60,000 average homes.

In June, CAMS was named to the Financial Times’ list of the 300 fastest-growing companies in North and South America. The company’s revenue grew more than 70 percent from 2020 to 2023.

Earlier this year, CAMS jumped into the super-hot data center sector with the rollout of services designed to help deliver reliable, cost-effective power to energy-hungry data centers. The initiative focuses on supplying renewable energy and natural gas.

Google's $40B investment in Texas data centers includes energy infrastructure

The future of data

Google is investing a huge chunk of money in Texas: According to a release, the company will invest $40 billion on cloud and artificial intelligence (AI) infrastructure, with the development of new data centers in Armstrong and Haskell counties.

The company announced its intentions at a meeting on November 14 attended by federal, state, and local leaders including Gov. Greg Abbott who called it "a Texas-sized investment."

Google will open two new data center campuses in Haskell County and a data center campus in Armstrong County.

Additionally, the first building at the company’s Red Oak campus in Ellis County is now operational. Google is continuing to invest in its existing Midlothian campus and Dallas cloud region, which are part of the company’s global network of 42 cloud regions that deliver high-performance, low-latency services that businesses and organizations use to build and scale their own AI-powered solutions.

Energy demands

Google is committed to responsibly growing its infrastructure by bringing new energy resources onto the grid, paying for costs associated with its operations, and supporting community energy efficiency initiatives.

One of the new Haskell data centers will be co-located with — or built directly alongside — a new solar and battery energy storage plant, creating the first industrial park to be developed through Google’s partnership with Intersect and TPG Rise Climate announced last year.

Google has contracted to add more than 6,200 megawatts (MW) of net new energy generation and capacity to the Texas electricity grid through power purchase agreements (PPAs) with energy developers such as AES Corporation, Enel North America, Intersect, Clearway, ENGIE, SB Energy, Ørsted, and X-Elio.

Water demands

Google’s three new facilities in Armstrong and Haskell counties will use air-cooling technology, limiting water use to site operations like kitchens. The company is also contributing $2.6 million to help Texas Water Trade create and enhance up to 1,000 acres of wetlands along the Trinity-San Jacinto Estuary. Google is also sponsoring a regenerative agriculture program with Indigo Ag in the Dallas-Fort Worth area and an irrigation efficiency project with N-Drip in the Texas High Plains.

In addition to the data centers, Google is committing $7 million in grants to support AI-related initiatives in healthcare, energy, and education across the state. This includes helping CareMessage enhance rural healthcare access; enabling the University of Texas at Austin and Texas Tech University to address energy challenges that will arise with AI, and expanding AI training for Texas educators and students through support to Houston City College.
