XPRIZE Carbon Removal Challenge: Meet The Top 20 Finalists - Carbon Herald

XPRIZE, an organization known for creating and managing competitive challenges aimed at addressing critical global issues, has announced the 20 finalists of the XPRIZE Carbon Removal competition. 

With a prize of $100 million at stake, participants are tasked with developing and showcasing innovative solutions capable of extracting CO2 from either the atmosphere or oceans and storing it in a long-lasting and environmentally friendly manner.

Since the start of the XPRIZE Carbon Removal in 2021, more than 1,300 teams from 88 different countries have taken part in the competition’s four pathways for removing carbon. These teams come from diverse backgrounds, such as scientists, engineers, technologists, students, and newcomers.
