- Union Minister for Finance Nirmala Sitharaman announced that the will be launched in 2021-22, during her budget speech February 1, 2021.
About Hydrogen Energy:
- Hydrogen is a clean fuel and it could serve as a possible substitute to liquid and fossil fuels.
- It is a nontoxic, odorless and highly combustible making it a potentially great energy source.
- Hydrogen can be created by splitting water into hydrogen and oxygen or by breaking the chemical bonds from compounds.
- Currently, global hydrogen production is 48% from natural gas, 30% from oil, and 18% from coal; water electrolysis accounts for only 4%.
- India’s mission will aim to create hydrogen from renewable energy sources.
- Hydrogen can fuel cells in zero-emission electric vehicles and the fuel cell has the potential for high efficiency. In fact, a fuel cell coupled with an electric motor is two to three times more efficient than an internal combustion engine running on gasoline.
- Hydrogen can also serve as fuel for internal combustion engines.
Advantages
- It is readily available, is renewable and is efficient.
- It doesn’t produce harmful emissions and is environmentally friendly.
- It is both powerful and efficient and can provide power for powerful machines such as spaceships.
- It is renewable. It can be produced again and again, unlike other non-renewable sources of energy. This means that with hydrogen, you get a fuel source that is limited. Basically, hydrogen energy can be produced on demand.
Disadvantages
- It is expensive and difficult to store.
- It is not easy to replace existing infrastructure.
- It is highly flammable.
- It is dependent on fossil fuels currently.
