• # question_answer 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

[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.
