Investors at the Rice Alliance Energy Tech Venture Forum have named the 10 most-promising startups among the group of 100 clean tech companies participating in the event.

The 22nd annual event was held yesterday, Sept. 18, at Rice University’s Jones Graduate School of Business and was part of the second Houston Energy and Climate Startup Week.

The most-promising startups will receive $7,000 in in-kind legal services from Baker Botts.

The 10 most-promising companies included:

  • Houston-based Xplorobot, which has developed laser gas imaging technology for the first handheld methane detection device approved by the EPA as an alternative test method
  • Seattle-based Badwater Alchemy, a desalination company that uses nano materials to purify saline water at a fraction of the cost of traditional methods
  • San Francisco-based Ammobia, which is developing a clean ammonia production process
  • Illinois-based Celadyne Technologies, which is building hydrogen for industrial decarbonization with durable and efficient fuel cells and electrolyzers
  • Massachusetts-based MacroCycle Technologies, which converts plastic waste in the form of bottles, food trays and polyester textiles into virgin-grade mPET resin
  • Massachusetts-based AtoMe, which uses nano-ceramics to develop ultra-durable metals for 3D printing
  • Colorado-based Advanced Thermovoltaic Systems (ATS) Energy, a renewable energy semiconductor manufacturing company
  • North Carolina-based Lukera Energy, which is converting waste methane into high-value fuel
  • Midland, Texas-based AI Driller, a company that uses AI and machine learning to enable remote operations and provide historical drilling data for survey management, anti-collision monitoring and iob reporting
  • New York-based Fast Metals Inc., which has developed a chemical process to extract valuable metals from complex toxic mine tailings that is capable of producing iron, aluminum, scandium, titanium and other rare earth elements using industrial waste and waste CO2 as inputs

Arculus Solutions won the People's Choice Award. The New Jersey-based company retrofits natural gas pipelines for safe hydrogen transportation. It also won Track A: Hydrogen, Fuel Cells, Buildings, Water, & Other Energy Solutions at the Energy Venture Day and Pitch Competition during CERAWeek earlier this year.

The 100 energy technology ventures selected to participate in the forum were named earlier this year. See the full list here.

Houston-based quantum energy technology startup Casimir Inc. has been awarded an STTR Phase I contract from the U.S. Space Force's SpaceWERX to support the development of the company's solid-state generator for potential use by the Department of the Air Force.

SpaceWERX is the innovation arm of the U.S. Space Force and a division within AFWERX, the incubator and innovation arm of the United States Department of the Air Force. The Air Force Research Laboratory and SpaceWERX, along with many other government agencies, help support innovation through the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) grants and contracts.

As part of the new contract, Casimir will work to refine a fully independent generator. Casimir’s solid-state power technology could support national security missions by providing reliable power even in difficult-to-service environments.

In May, Casimir emerged from stealth, netting a $12 million seed round to commercialize its quantum energy chip. The semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company aims to include the chips in large-scale energy systems that can power homes, commercial infrastructure and electric vehicles.

“This STTR funds some analysis work to address our proposed scaling approach of making our chips multi-layer to increase aggregate power,” Harold “Sonny” White, founder and CEO of Casimir, tells Energy Capital.

White adds that the company will work with Texas A&M to develop chip planarization techniques to support Casimir’s plans to scale. Additionally, White says the company is working with the U.S. Space Force to explore more applications for its technology.

“Casimir’s technology brings a new capability to the market in the form of our persistent power chips,” White adds. “This approach will be relevant to ultra-low-power electronics, and with the scaling approach we are developing, connected with the STTR work, will eventually be relevant to consumer electronics and beyond.”

Casimir has previously reported that it plans to commercialize its first-generation MicroSparc chip by 2028. The chips are expected to power devices for years without the need for replacements.

The total funding for this project has not yet been disclosed.
