The answers

Question 1 · 10 marks · 181 words written

"Green hydrogen can be the silver bullet in our quest to tackle climate change and pollution". Critically analyse the statement in light of India's National green hydrogen mission.

Opening · a figure

Ministry of New and Renewable Energy has launched the National Green Hydrogen Mission, with an outlay of 19,774 cr and objective to generate 5 GW of energy.

Green Hydrogen -> Hydrogen produced through renewable sources of energy.

Advantages of Green Hydrogen

Body · points

(i) Tackling climate change (1) Decarbonisation of industries. (2) Green transportation -> shipping, railways etc. Reduces dependence on fossil fuels & COx, NOx, SO2 etc. (3) Releases only water vapour as the by-product -> does not release GHG's. (4) Better energy efficiency.

(ii) Tackling pollution (1) Reduces vehicular and industrial emissions. (2) Reduce the concentration of PM 10 and 2.5 -> major sources of pollution.

Limitations of green Hydrogen (1) Costly -> generation of heat through electrolysis, using renewables is a cost-intensive process. (2) Storage and transportation -> Green H2 is volatile. (3) Water intensive -> to produce 1MW of electricity using H2, 19000 L of water is required. (4) Seasonality and unpredictability of renewable sources like solar & wind.

Close · a summary

Therefore, Green Hydrogen is a promising endeavour towards decarbonisation of Indian economy, and to achieve Net carbon neutrality by 2070.
