 Almost two years ago, I published a list of every direct air capture (DAC) company in the world to support job seekers, analysts, and various other groups in understanding the actual DAC landscape on the ground. I received a ton of positive feedback regarding the impact of the list, including from some unexpected groups like industrial equipment vendors. Ultimately, the project informed the development of an official DAC definition and company analysis report I put together while working at the Department of Energy, which drove additional attention to and insight into the space.

To expand on this effort, I painstakingly combed through dozens of other CDR company lists and leveraged my experience in the industry to develop what I believe is the most comprehensive and up-to-date CDR company list in the world. To focus the list, it only includes active, incorporated companies working on durable CDR and excludes artisanal biochar. Please see below to explore.”

Greg and list:
 
    Thanks for the lead.  
 
     Your quote was by a Grant Faber.   Recently on a podcast discussing his list (of 700 companies).  Biochar close to 300/700, and with others labeled BICRS. - I heard 60% of the total,   Second place was DACS.
 
     Faber seemed quite knowledgeable and credible. Background in DACs.
 
     Apparently many more biochar companies; that he excluded -  all called "artisanal".  I think that's reasonable.
 
 
      I may be on a list to see the 700,  but haven't yet seen the list.
 
      He said he thought he had a 90% chance of getting 90%  (so not likely to be 800 CDR companies).   I would guess he could be correct if he had 100 Chinese biochar  companies.  The word "China" didn't appear once in the webinar - but they've produced about 50% of biochar's technical papers (and most are high quality).  Other lists of biochar companies I've seen have close to zero from China.
 
Ron.
