Bell Resources
Bell Resources is building AI-powered Roadside Hubs that fold ultra-fast EV charging, automated car washing, clean energy and smart retail into a single connected stop.
Nanosys
Nanosys is a Silicon Valley materials company, founded in 2001 in Milpitas, California, that makes quantum dots - man-made semiconductor crystals 2 to 8 nanometers across that convert light into precisely tuned, saturated color. Its Quantum Dot Enhancement Film (QDEF) helped bring wide-color-gamut displays to mass market, and its materials have shipped in more than 70 million televisions, monitors, tablets and phones. Nanosys holds one of the largest quantum dot patent portfolios in the world and is developing NanoLED (QDEL), a self-emissive display technology in which quantum dots make their own light. In September 2023 its quantum dot business was acquired by Japan's Shoei Chemical, which now operates the Nanosys brand and its Milpitas R&D labs.
Aepnus Technology
Aepnus Technology is an Emeryville, California cleantech startup that builds ultra-efficient, catalyst-free electrolyzers to turn sodium sulfate - a low-value waste salt produced in enormous volumes by battery-material and critical-mineral plants - back into two industrial staples: caustic soda (sodium hydroxide) and sulfuric acid. By splitting waste salt on-site with renewable electricity, Aepnus lets manufacturers cut disposal costs, reduce emissions, and shorten fragile chemical supply chains, converting a roughly $350-per-tonne waste-handling problem into about $700 of usable reagents per tonne.
Molten Industries
Molten Industries is an Oakland, California climate-hardware startup that uses methane pyrolysis to crack natural gas into clean hydrogen and high-value synthetic graphite, with no carbon dioxide emitted in the process. Founded in 2021 by Dr. Caleb Boyd and Dr. Kevin Bush, the company aims to onshore battery supply chains and decarbonize heavy industry by producing battery-grade graphite for lithium-ion cells and low-cost clean hydrogen for fuels, ammonia, plastics, and green steel. It raised a $25M Series A in June 2024 led by Breakthrough Energy Ventures to build its first modular commercial reactor.
Titan Advanced Energy Solutions
Titan Advanced Energy Solutions is a Salem, Massachusetts battery-tech company that uses non-destructive ultrasound and industrial AI to inspect lithium-ion cells at production speed. Its IonSight Digital Teardown platform images the inside of every cell on a manufacturing line - catching layer misalignment, contamination, dry zones, and other hidden defects that CT sampling and electrical tests miss - to improve battery quality, safety, and yield for EVs, grid storage, and consumer electronics.
Matter
Matter is an Ahmedabad-based deep-tech mobility and energy company best known for the Aera, India's first geared electric motorcycle. Founded in 2019 by Mohal Lalbhai and a team of engineers, Matter designs and manufactures connected electric two-wheelers with a four-speed manual gearbox and liquid-cooled lithium-ion battery packs, alongside a separate line of stationary and mobility energy-storage products. The company runs its own next-generation factory in the Ahmedabad region and has raised tens of millions in venture funding to scale production of vertically integrated, India-specific EVs.
