1. Carbon and other things capture transport
Convert to value added products or storage
It is the only path to a negative emission
Collection of some techs, always important


2. Most common separate, post combustion
Coal gas biomass and air in power and heat
Pre combustion takes out CO2 from gas, air, oil early
It is taken out when there's reformer


3. If O2 separated from air in
Through power, heat, reforms CO, oxyfuel
Coal gas biomass air and O2 and a raw material
Makes steel, gets CO2 in industrial process


4. All the flue gases are separated
CO2 compression dehydration
It loses electrons to oxygen for water to form
Further accept from O2 to H2CO3


5. CO2 captured in an absorber
When flue gas comes in, it's vented out soon
Then releases at high Ea, with CaO as the oxide
Solvent's electron grabbing piperazine


6. They react together, forms FCC carbonate
It has membrane, separates other gases
Released at high temp, water to heat recovery exchanger
At 71 degrees water is gone


7. IGCC, which is pre combustion
Is most efficient type of CCUS
Oxyfuel not much better, cause energy for pure O2
Gas uses less energy, but more cost to capture


8. CO2 stored in underground and ocean
In oil gas resources, where they come from
They are used for oil recovery which pushes the oil up
So CO2 stays under ground easily


9. It needs a stainless steel casing with cement
Prevents leaking, but empty space will leak
It can be used for natural gas, coolants, chemicals, fuel cells too
Or minerals from oxide reaction
