Green Hydrogen
Why In News:
Scientists have discovered how a molybdenum carbide (Mo₂C) catalyst reconstructs itself during water electrolysis to produce green hydrogen more efficiently.
Key Findings:
Scientists discovered how the Mo₂C catalyst reconstructs itself during water electrolysis to produce green hydrogen.
In-situ XAS (X-ray Absorption Spectroscopy) and Raman studies showed the formation of an active MoOₓ phase.
Controlled reconstruction enhances efficiency, while uncontrolled oxidation reduces catalytic activity.
Key Facts for Prelims
Green Hydrogen: Hydrogen produced by electrolysis of water using renewable energy, with near-zero carbon emissions. (Grey = from fossil fuels; Blue = fossil fuels with carbon capture.)
Electrolysis splits water (H₂O) into hydrogen and oxygen using electricity; a catalyst lowers the energy required for the reaction.
National Green Hydrogen Mission was launched in 2023 with an outlay of ₹19,744 crore; target of 5 MMT (Million Metric Tonnes) annual production capacity by 2030.
Nodal ministry: Ministry of New and Renewable Energy (MNRE).
Green hydrogen supports decarbonisation of hard-to-abate sectors — steel, fertilisers, refineries and long-haul transport.
