Carbon capture and utilization
Part of: Prelims and GS III – Environment
Context: A group of scientists from Indian Institute of Chemical Technology, IICT, Hyderabad have designed a hybrid material which can absorb greenhouse gas methane and convert it to clean hydrogen.
- They have simulated a process of capturing carbon dioxide and converted it to high purity hydrogen from non-fuel grade bioethanol.
- These scientists have also designed a facility that can test such materials and help further carbon capture research at the institute.
- The Ministry of Science and Technology in a statement said that these new materials and processes for carbon capture and utilisation could show new light for the global warming challenge.
What is Carbon capture and utilization?
- Carbon capture and utilization (CCU) is the process of capturing carbon dioxide (CO2) to be recycled for further usage.
- Carbon capture and utilization may help in significantly reducing greenhouse gas emissions from major industrial emitters.
- CCU is different from carbon capture and storage (CCS) because CCU does not aim nor result in permanent geological storage of carbon dioxide.
- Instead, CCU aims to convert the captured carbon dioxide into more valuable substances or products; such as plastics, concrete or biofuel; while retaining the carbon neutrality of the production processes.
- Methane is a gas that is found in small quantities in Earth’s atmosphere but it is a powerful greenhouse gas.
- Methane is 84 times more potent than carbon but it doesn’t last as long in the atmosphere before it breaks down.
- It is also responsible for creating ground-level ozone, a dangerous air pollutant.
