Today, @BloombergNEF published its annual #CCS Market Outlook. The tl:dr is that, based on current announcements, CCS capacity is set to grow 6x by 2030. That’s 44% higher than what we expected last year. And it’s before you take #IRA into account. 🧵 with some key results:
(2/10) CCS is diversifying. Most of the capture will be happening in #industry and #power, rather that natural gas processing. And most of the CO2 will be going in the ground, not to oil wells for EOR.
(3/10) We’ve been saying transport and storage infrastructure could be a bottleneck. *For the moment* it doesn’t look like a problem. There’s more unallocated capacity than capture projects looking for a home for their CO2. This can change quickly, given all that Midwest #ethanol

...this leads to a potential #CDR of 15,591 Gt-CO2...so more than we need for #2DS.
But, most of that rock is volcanic (amorphous).
Previously we found that amorphous compounds react >1,000X slower than equivalent crystalline compounds.

If we went hit net-zero or carbon neutral today, how much carbon do we need to remove to maximize diversity and climate restoration by 2100? See thread for more info on #beyondneutral #climateaction #climatejustice @ExtinctionR
Fossil fuel emissions since 1750, have spread between the air, oceans, and land. By the latest count per the globalcarbonproject.org, the distribution looks like the linked chart. Multiply by 3.664 to convert the amounts to gigatonnes carbon dioxide. (1.7 Tt CO₂ & 2.4 Tt CO₂)
How big is this amount? The brown+red bars equals about 656 Gt Carbon by weight which is about 2M Empire State buildings. This amount is roughly equal to all green and blue bars and should be removed to restore the planet. bluebulbprojects.com/measureofthing…
