Hi Paul, All - 

Based on my experience working closely with Frontier, I can tell you the main issue is not as described: it’s that the science needs to evolve to a point where 1000+ years permanence is justified. Even our scientists at Puro.earth will not guarantee that durability because so much can happen in that period of time.

Biochar producers could ostensibly get in with Frontier if/when the biochar is stored in concrete. 2 other possibilities that may work: lock up biochar deep in an old mine or pump it underground as a slurry (geological storage). Keep in mind that Frontier, while important, is but one buyer. Microsoft is very open to mid-term durability CDR solutions and is a big buyer of biochar CORCs. Focus on scale - and credit registration (such as with Puro) - and your odds of success are greatly increased. You also need to apply with Microsoft. Listing on our platform provides more visibility to lesser known but important international buyers of negative emissions.

There is a lot happening in the space right now. All I can say is competition for large quantities of credits is getting more intense every day. Scale and you’ll be rewarded for your work.

Best of luck in your journey,

-Joe
