Blue chemicals with low-cost pre-combustion CO2 capture: The first places to look for CCUS opportunities


Post-combustion carbon dioxide (CO2) capture will be essential to produce green steel, decarbonise cement making and mitigate CO2 emissions from fossil-fired power generation.

However, post-combustion CO2 capture after air-fed combustion is expensive, since the CO2 concentration is low, and a huge volume of nitrogen gas must be processed.

Pre-combustion CO2 capture, on the other hand, is cost effective and can be retrofitted to more than 1,000 operational SMRs around the world to decarbonise hydrogen production.
