Rewind "restore the earth's carbon balance by storing #OrganicCarbon in anoxic water."

#CarbonDioxideRemoval

Details in a 🧵 below ⬇️

Plants are the best option for capturing CO2

"They naturally extract CO2 from the air and use it as feed. The more CO2 plants absorb, the less CO2 remains trapped in the atmosphere."
2/6 Image
As plants decompose, CO2
is released back to the air

"If left alone, plants are eaten by other organisms and releasing the carbon back to the carbon cycle within months."
3/6
Anoxic conditions slow decomposition

"In anoxic waters, plants decompose extremely slowly, effectively storing the carbon much longer."
4/6 Image
The Black Sea is the ideal location

"It is the largest anoxic body of water on earth, 2km deep, surrounded by fertile lands. The Black Sea is the optimal environment allowing affordable, environmentally safe, gigaton scale #CarbonRemoval in this decade."

🚨What if we bet too much on future carbon removal tech and it doesn’t deliver?

New study shows that over-relying on #CDR like DACCS & BECCS could let fossil fuel emissions continue longer, delay action, and raise costs later.

Key findings🧵1/9 Image
2/ Many net-zero plans assume large-scale CDR. But techs like direct air capture (DACCS) & bioenergy with CCS (BECCS) are tiny today and scaling them is risky due to land, energy & cost barriers.
3/ Researchers ran 6 scenarios using GCAM:

-Stage 1: Plan for high or low CDR now
-Stage 2: Learn mid-century whether high CDR is actually feasible or not, and then adjust policy or not

They tracked emissions, energy shifts, costs & who bears the burden. Image
