About Travertine

Travertine is a Climate Tech start-up based in Boulder, CO that is rapidly scaling an electrochemical technology for carbon dioxide removal (CDR) and sustainable critical element extraction. Our process takes carbon dioxide from the air and sources of waste sulfate to produce carbonate minerals, sulfuric acid, and hydrogen. The sulfuric acid is used in extraction of critical elements like lithium and nickel for EV batteries and phosphorus for fertilizer. The Travertine Process was developed by Prof. Laura Lammers at her UC Berkeley lab. Travertine was founded in 2022 to scale this process to gigatons per year of CDR. 

In 2022, we raised a seed round from the Grantham Foundation and Clean Energy Ventures, we were one of the first companies to receive pre-purchases of CDR from the new Stripe-led $1B Frontier fund, and we received a $2M grant from the DOE’s ARPA-E program. We were also named C&EN 10 startups to watch in 2022 and a Bloomberg NEF Pioneer in 2023.  We believe in developing practical approaches to solving the climate crisis. And we are rapidly scaling up our system.
