With reference to green hydrogen, consider the following statements: 1) t can be used directly as a fuel for internal combustion. 2) It can be blended with natural gas and used as fuel for heat or power generation. [2023]

With reference to green hydrogen, consider the following statements:

It can be used directly as a fuel for internal combustion.
It can be blended with natural gas and used as fuel for heat or power generation.
It can be used in the hydrogen fuel cell to run vehicles.

Green hydrogen has numerous applications and can be used in fuel cells to power vehicles and provide electricity. It can indeed be used directly as a fuel for internal combustion. Hydrogen fuel cells have a high energy density and are more efficient than traditional combustion engines, making them an attractive option for powering vehicles. It can be blended with natural gas and used as fuel for heat or power generation.

Hydrogen is a colourless, odourless, highly flammable, non-toxic gas.
It is the lightest and most abundant element in the universe.
On earth, it never occurs freely. It exists combined with other elements, e.g., water (H2O).
It has to be produced using other sources of energy. Hence, it is an energy carrier (like electricity) and not an energy source.
Hydrogen is a clean molecule that produces only water and water vapour as by-products when used as fuel. However, the process of extracting it is energy-intensive.
Energy carriers: They allow energy transport in a usable form from one place.
Green Hydrogen, is produced by the process of electrolysis, where water is split into hydrogen and oxygen using electricity generated from renewable sources like solar, wind, or hydropower.
This process results in a clean and emission-free fuel that has immense potential to replace fossil fuels and reduce carbon emissions.
- Electrolysis: The process by which electric current is passed through a substance to effect a chemical change. In a chemical change, the substance loses or gains an electron (oxidation or reduction).
Another method of producing Green Hydrogen is from biomass, which involves the gasification of biomass to produce hydrogen. Both these production methods are clean and sustainable, making Green Hydrogen an attractive option for the transition to a low-carbon future.
