Green Hydrogen Microgrid ProjectTags :
Why in News?
- National Thermal Power Corporation Limited (NTPC) has awarded the first Green Hydrogen Microgrid Project at Simhadri in Andhra Pradesh.
- It would be a precursor to large-scale hydrogen energy storage projects and would be useful for studying and deploying multiple microgrids in various off-grid and strategic locations of the country.
- The hydrogen would be produced using the advanced 240 kW Solid Oxide Electrolyser by taking input power from the nearby Floating Solar project.
- It is a unique project for India and would open doors for decarbonizing the far-off regions of the country like Ladakh, J&K, etc, hitherto dependent on diesel generators.
Green Hydrogen: Any hydrogen that is produced from clean energy sources like renewables.
- ‘Green’ hydrogen is released via electrolysis of energy from renewable sources.
- Green hydrogen is produced by splitting water into hydrogen and oxygen using an electrolyzer powered by electricity from renewable energy sources such as wind and solar.
Grey Hydrogen: Hydrogen produced from fossil fuels via carbon-intensive processes is called grey hydrogen.
Blue Hydrogen: Grey hydrogen becomes ‘blue’ hydrogen when the CO2 given out during its production is locked up through carbon capture and storage (CCS) processes.
Applications of Green Hydrogen:
- Green Chemicals like ammonia and methanol can directly be utilized in existing applications like fertilizers, mobility, power, chemicals, shipping, etc.
- Green Hydrogen blending up to 10% may be adopted in CGD networks to gain widespread acceptance.
National hydrogen Mission:
It focuses on producing green hydrogen and using it as clean energy to achieve the target of net-zero emission.
Benefits of hydrogen energy:
- It is a clean-burning molecule, which can decarbonize a range of sectors including iron and steel, chemicals, and transportation.
- Renewable energy that cannot be stored or used by the grid can be channeled to produce hydrogen.
Challenges towards Using Hydrogen Energy
- The cost of developing technologies to produce ‘green’ hydrogen is cost-intensive.
- Hydrogen is not a source of energy, like fossil fuels or renewable sources like sunlight and air, but an energy carrier, which means it has to be produced, or extracted, and stored before it can be used.
