[pib] Recycling Carbon Technology


From UPSC perspective, the following things are important :

Prelims level : Components of CCUS

Mains level : Carbon sequestration

A Bangalore-based startup has received the National Award 2021 for developing efficient catalysts and methodologies for the conversion of CO2 to methanol and other chemicals.

Carbon Recycling

  • It has led to the improvisation of process engineering to enhance the production of chemicals and fuels from anthropogenic CO2.
  • It has integrated multiple components involved in the CCUS (Carbon capture, utilization, and sequestration) to develop a complete solution for the environmental issues due to global warming.
  • The current capacity of CO2 conversion is 300 kg per day, which can be scaled up to several 100 tons on an industrial scale.

What is CCUS?

  • Carbon Capture, Utilization, and Storage (CCUS) encompass methods and technologies to remove CO2 from the flue gas and from the atmosphere.
  • CCUS involves multiple aspects that need to be in sync for the successful removal or capture of CO2 from the flue gas or the atmosphere, followed by utilization and storage.
  • Carbon capture involves the development of sorbents that can effectively bind to the CO2 present in flue gas or the atmosphere, which is expensive.
  • In addition, there has been a considerable debate about the fate of captured and compressed CO2.
