Twelve: Etosha Cave
Play • 1 hr 4 min

Etosha Cave, Co-founder and CSO of Twelve, on the sacrifices she made while launching Twelve:

“I had no money.  I was living out of my car at Lawrence Berkeley National Lab.”

Etosha became passionate about energy and climate change while growing up in Houston, and she went on to receive her PhD from Stanford University focusing on electrochemical approaches that could be used to convert CO2 and water into useful plastics and household cleaners.  While at Stanford, Etosha co-founded Twelve, a startup pioneering a new market category called carbon transformation with its proprietary catalyst technology that transforms CO2 into critical chemicals, materials and fuels that are conventionally made from fossil fuels.  Using Twelve’s technology, industry brands can meet emissions targets faster while creating essential products–from the foam in running shoes, to the polymers in automobile dashboards, to aviation fuel, to laundry detergent–all while maintaining  the same or higher quality as conventional products made from petrochemicals.

As always, HUGE shout out to Climate Tech Cocktails official sponsors ☀️Yotta Energy and 💎Aether Diamonds

Enjoy the show!


This episode is brought to you by ☀️Yotta Energy !  We all know energy storage is key to deploying renewables at scale. I’ve seen many energy storage solutions for commercial buildings over my years in climate tech, but none as impressive as Yotta’s.  

Yotta Energy’s unique "PV-Coupled" ecosystem of solar+storage solutions simply integrates within the standard solar installation process. Even better, their integrated storage technology can enable up to 60% more solar to be deployed on commercial buildings.  With commercial buildings consuming 35% of US electricity that means Yotta is making a serious dent in CO2 emissions. With the electrification of everything revolution underway, Yotta Energy is poised to meet the growing demands of electrification by sizing solar+storage resources to recharge electric vehicles as they future proof buildings into distributed energy sites powering the grid of the future.
