Read this question in English
With reference to green hydrogen, consider the following statements:
1. It 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.
3. It can be used in the hydrogen fuel cell to run vehicles.
How many of the above statements are correct?
(a) Only one · (b) Only two · (c) All three · (d) None
उत्तर और व्याख्या · explanation in English
Answer: (c) सभी तीन
All three statements are correct. Green hydrogen is hydrogen made by splitting water with renewable electricity, and it is chemically the same fuel as any other hydrogen: it can burn in an engine, be mixed into natural gas, or feed a fuel cell.
- ✓ 1. Hydrogen internal combustion engines are in use: India's pilot projects under the National Green Hydrogen Mission include 22 hydrogen internal-combustion vehicles.
- ✓ 2. Hydrogen is already being blended into gas networks in India, for example up to 8% by volume in a piped natural gas network in Surat, for use as fuel.
- ✓ 3. Hydrogen fuel cells power vehicles; the same pilot projects include 15 fuel-cell vehicles, and hydrogen fuel-cell buses already run in Leh and Greater Noida.
Remember · Green hydrogen (made by electrolysis with renewable power) works as engine fuel, as a blend in natural gas, and in fuel cells for vehicles.
