Halliburton Labs has named five companies to its latest cohort, including one from Texas.

All of the companies are working to help accelerate the future of the energy industry in different ways. The incubator aims to advance the companies’ commercialization with support from Halliburton's network, facilities and financing opportunities.

The five new members include:

  • 360 Energy, an Austin-based in-field computing company with technology that is able to capture flared or stranded gas and monetize it through modular data centers
  • Cella, a New York-based mineral storage company that provides end-to-end services, from resource assessment to proprietary injection technology, and monitoring techniques to provide geologic carbon storage solutions
  • Espiku, an engineering services company based in Bend, Oregon, that finds solutions that advance water and minerals recovery from brines and industrial-produced water streams
  • Mitico, based in Los Angeles, that offers technology services to capture carbon dioxide by using its patent-pending granulated metal carbonate sorption technology (GMC) that captures more than 95% of the CO2 emitted from post-combustion point sources
  • NuCube, a Pasadena, California-based company with a nuclear fission reactor under development

“We welcome these innovative energy startups,” Dale Winger, managing director of Halliburton Labs, said in a news release. “We are eager to help these participant companies use their time and capital efficiently to progress new solutions that meet industry requirements for cost, reliability, and sustainability.”

Halliburton Labs also announced that it will host the Finalists Pitch Day on March 26, 2025, in Denver for energy and decarbonization industry innovators, startups and investors ahead of the National Renewable Energy Laboratory (NREL) Industry Growth Forum. The pitch event will precede registration and the opening reception of the NREL forum. Find more information here.

Adena Power, an Ohio-based clean energy startup, was the latest to join Halliburton Labs prior to the new cohort. The company used three patented materials to produce a sodium-based battery that delivers clean, safe and long-lasting energy storage.

The incubator also named San Francisco-based venture capital investor Pulakesh Mukherjee, partner at Imperative Ventures, which specializes in hard tech decarbonization startups, to its advisory board last spring.

Veolia, a Boston-based company with major operations in Texas, is purchasing hazardous-waste company Clean Earth from Enviri as part of a $3 billion deal.

Veolia is a private water operator, technology provider and hazardous waste and pollution treatment company that operates a large hazardous waste treatment and incineration facility in Port Arthur. Hazardous waste treatment is a growing sector as the clean energy, semiconductor manufacturing, healthcare and pharmaceutical industries generate high levels of waste that need to be handled safely.

Acquiring Clean Earth’s 82 facilities, which include 19 EPA-permitted sites, will expand Veolia’s reach into 10 new states and will position the company as the second-largest hazardous waste operator in the U.S., according to a news release. The deal is Veolia’s sixth and largest North American acquisition of 2025.

“(The acquisition) allows us to unlock the full value potential of our U.S. hazardous waste activities and to double our size on this critical, fast-growing sector, creating a No. 2 player,” Estelle Brachlianoff, CEO of Veolia, said in a news release. “We reinforce our global capacities in hazardous waste and further increase our international footprint.”

Veolia’s Port Arthur facility specializes in servicing generators with large-volume waste treatment requirements.

The transaction is expected to close mid-2026. Veolia hopes the increased exposure into industries such as retail and healthcare will help to offer a full range of environmental services across the U.S.

“This continued transformation of our portfolio enhances the growth profile and strength of our group, uniquely positioned to tackle the sustained demand for environmental security,” Brachlianoff added in the release.
