Two XPRIZE Winning Teams


On April 22nd, XPRIZE announced the 15 winners of the second round of their competition for carbon removal solutions. Each of these teams has been awarded $1 million to help them compete for the grand prize of $50 million, or 3 $30 million runner-up slots, awarded three years from now.

The grand prize winner may not be one of the 15 Milestone awardees, but these teams are a step ahead of the competition and have already demonstrated an ability to impress the Xprize judges.

This episode features two segments with interviews of Milestone-winning teams.

First, Radhika and Na’im spoke with Carbin Minerals CTO Peter Scheuermann. Carbin’s work with mine waste streams is based on the pioneering research of Dr. Greg Dipple. Peter joined us to discuss how they plan to make mining carbon negative, their testing so far, and how their MRV approach will be “modular.”

In the second segment, CRN producer Asa Kamer fills in as guest host to talk with the two companies who make up the XPRIZE team “Project Hajar”: Mission Zero and 4401. 4401 Commercial Lieutenant Karan Khimji and Mission Zero CEO Nicholas Chadwick join us for a discussion on their DAC to Mineralization approach in Oman, their progress so far, and what keeps them up at night as they scale up.
