| Impending crisis of global warming has overwhelmed humanity at large. Which of the following are the name of technologies, could be used for carbon-sequestration? |
| 1. NOTT-202 |
| 2. Ocean-iron fertilisation |
| 3. BECCS |
| Select the correct answer using the codes given below. |
A) 1 and 3
B) 1 and 2
C) 2 and 3
D) All of these
Correct Answer: D
Solution :
[d] NOTT-202 is 'metal-organic framework that works like a sponge, absorbing a number of gases at high pressures but as pressure is reduced, \[C{{O}_{2}}\] is rejoined as others are released. As per reported in 'Nature' magazine, NOTT-202 holds promise for carbon capture and storage. Through ocean- iron fertilisation, iron particles are added in layers of ocean, which induces growth of phytoplankton. Phytoplankton in turn absorb carbon from atmosphere. BECCS refers to bio-energy induced carbon capture storage. One of way is trapping methane in seams of rock only.
