10 Innovators Recognized for Exceptional Achievements

San Francisco, CA – January 22, 2024 — Cleantech Group today recognized 10 exceptional companies who have made significant progress in championing sustainable innovation.  These winners were celebrated at an awards dinner at the kick-off evening of Cleantech Forum North America.

Nine of these companies were part of the 2024 Global Cleantech 100, an annual list of the most innovative and promising companies that will take us from commitments to actions in our efforts to reach net-zero. The other private company was recognized for its positive acquisition, after many years as a Global Cleantech 100 company.

“In this era of climate stuckness, when the mood music gets a bit gloomy, these distinguished companies remind us that transformative solutions are continuing to make remarkable progress around the world,” said Richard Youngman, CEO of Cleantech Group.

Honors companies with the highest ranking in the list this year in each of three regions:

North America: Aeroseal has created a process that seals the central heating/cooling and ventilation ductwork within residential homes and commercial buildings.

Europe & Israel: Energy Dome creates long-duration electricity storage solutions using liquid CO₂.

Asia-Pacific: Plotlogic provides LiDAR, hyperspectral imaging and machine learning algorithm technologies to autonomously characterize materials in mining.

Early-Stage Company of the Year

Awarded to the highest-ranked product development/pre- or early-revenue company on the list:

Cyclic Materials is a circular supply chain service platform facilitating the recycling of rare earth elements via its proprietary Mag-Xtract and Hydrometallurgy technologies.

Rising Star Company of the Year

Awarded to the highest-ranked new entrant on the list, appearing on the list for the first time.

There were two Rising Stars awards made:

Resources & Environment: Nth Cycle has a modular system to refine critical metals from e-waste using a unique electro-extraction process.
Energy, Power & Mobility: ChargerHelp!  performs on-demand repairs and maintenance support for charging stations.

Graduate of the Year

Graduate of the Year via M&A: GaN Systems. Infineon acquired GaN Systems for $830M to boost its position across all relevant power technologies. GaN technology can enable more energy-efficient and CO₂-saving solutions in applications like mobile charging, data-center power supplies, residential solar inverters, and onboard chargers for electric vehicles.

Hall of Fame
Recognizes the achievements of the few companies whose sustained excellence has resulted in being on the Global Cleantech 100 list an impressive 7X. To maintain widespread support among investors and technology scouts in the market year-over-year is a great achievement. Once inducted into the Hall of Fame, companies will not be featured on any future editions of the list.

Minesense is a pioneer in digital mining solutions, supplying real-time, sensor-based ore sorting for mines. In the era of growing concern about future shortages of critical minerals to enable a decarbonized economy, this type of solution’s potential to boost output of the mining activity already happening, by say 5-15%, is important.

tado has been pioneering smart thermostats for heating and cooling in Europe since its founding in 2011. Based in Germany, it is now scaling increasingly across Europe, offering millions of homeowners both savings on their rising energy costs and a reduction in their CO₂ emissions.

Vestaron has been proving the idea that safe and effective pest control can also be biological and sustainable, through its peptide-based insecticide technology. The company first debuted on the list in 2013 but has become a regular returnee under new leadership since 2018.
