TL,DR: What are the problems to solve for efficient CC?
Answer that's missing in the article:
CO2 is one of the stablest elements in the atmosphere. Removing it will require humongous amounts of energy (as a rule of the thumb, more energy than the energy-producing process that generated this CO2 in the first place). Therefore CC at scale is probably a pipe dream and will remain so, because thermodynamics.
- AyrtonB 6y agoMost of the energy used in CO2 capture through amine absorption is in the form of heat. Luckily, most processes where point-source CCS could be used produce waste gas streams at very high temperatures which can significantly reduce the additional energy that needs to be added.
