Question 15GS3GS1

Discuss the potential of natural hydrogen as a fuel to meet growing global energy demands? Why is it still an untapped industry? (Answer in 250 words)

Open scan (p.38)

Main Body

As per IEA, world global energy demand will triple in next decades due to rise in AI, technology spread of industrialization and rising consumption. [Good Catch]

Potential of natural hydrogen

1Abundance availability in Nature: 0.03% in Atmosphere
2Renewable in nature: unlike fossil fuel
3No pollution due to use of hydrogen combustion unlike CO2 in coal
H2 + O2 → H2O (water)
4Water supply: still implement fresh water concern by 2030 according wait (CN177)
Limited mining issue of pollution

Ways to tap green hydrogen potential:

1Nation level plan: National green hydrogen mission (10,000 cr) 6 million metric ton by 2030
2International: technology share, forum 'in line with IEA'
3Centre of excellence for green hydrogen
4Alternative storage mechanism
They, as pmd highlighted green hydrogen's key to India (500 Acs) longevity

ecosystem disruption, displacement of totals.

9Low cost at high scale (IEA) plus
2 GHz Cheaper water purification
7Reduce import dependency: on OPEC countries
India 85%, crude oil import (66 Survey)
8Local production: by factories possible as per demand via A2 hydrogen policy
9Safe: unlike nuclear: adds carbon waste.

Untapped Industry:

Reasons for untapped Industry:

1Storage issue: as hydrogen fuel/volume is low compare to LNG.
2High capital cost for electrolysis and import dependency.
3Low R&D and lack of technology from West. Cathodic&
4Coal cheaper: so selective to shift.
5Not clean energy: as electricity used produced by coal.
6Requires high temperature (2000°C) and stabilizing technology lack-safety threat

Ways to tap green hydrogen potential:

2International: technology share, forum 'in line with IEA'
3Centre of excellence for green hydrogen
4Alternative storage mechanism
