Grey Hydrogen
Subject – Environment
Context – IOC plans to use grey hydrogen to make aviation fuel
Concept –
- Indian Oil Corporation (IOC) will put up a ‘demo plant’ within the next two years to convert ethanol into a biogas that would be used to run aircraft.
- The ‘alcohol-to-jet’ fuel (ATJ) plant will also use up its refiner’s grey hydrogen to produce the ethanol.
- There would be a lot of demand for biogas for aviation when the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) emission norms kick in in 2027.
- Also, there is going to be a huge increase in the demand for ethanol when the government of India’s mandate for mixing 20 per cent ethanol with petrol kicks in in 2025.
- Meanwhile, IOC plans to do a ‘no harm test’ on a pipeline to see which steel metallurgy can withstand some amount of hydrogen without suffering embrittlement.
Carbon Offsetting and Reduction Scheme for International Aviation
- The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) is a carbon offset and carbon reduction scheme to lower CO2 emissions for international flights, to curb the aviation impact on climate change.
- Developed by the International Civil Aviation Organization (ICAO) and adopted in October 2016.
- Its goal is to have a carbon neutral growth from 2020.
- CORSIA uses Market-based environmental policy instruments to offset CO2 emissions: aircraft operators have to purchase carbon credits from the carbon market.
- Starting in 2021, the scheme is voluntary for all countries until 2027.
