This report explains that CCUS will play an essential role in meeting India’s global commitments of reducing CO2 emissions by 50% by 2050 and achieving net zero by 2070.
Extract:
There are different categories and types of commercial-scale carbon capture technologies and their suitability or appropriateness for different applications/sectors depends on the typical CO2 gas stream composition:
a. Chemical solvent-based CO2 capture technologies: preferred when dealing with gas streams that are lean in CO2 and have relatively lower pressures, such as flue gas streams from power plants, BF gases in steel plants, gas streams in refineries or chemicals plants. The cost and availability of steam is also a key factor as regenerating the solvent requires large quantities of steam.
\b. Physical solvent-based CO2 capture technologies: these work well on gas streams with relatively higher CO2 concentration and pressure, such as pre-combustion capture in the case of gasification projects.
c. Adsorption-based CO2 capture: suitable for gas streams with moderate to high pressure and moderate CO2 concentration such as SMR flue gas or BF gas.
d. Cryogenic CO2 capture: preferred in cases where the cost of power is low. This technology can be applied for carbon capture from the PSA tail gas of Steam Methane Reforming Units (for producing H2 ) and provides a unique advantage of increasing the yield/recovery of hydrogen production from the same quantity of feedstock (natural gas).
