With reference to green hydrogen, consider the following statements:

Question

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

Answer 1

Answer:(b) Only two.

Explanation:

Statement 1 states that green hydrogen can be used directly as a fuel for internal combustion. This statement is incorrect. Green hydrogen, which is produced through electrolysis using renewable energy sources, is primarily used as a feedstock for various industrial processes and as a source of clean energy. It is not commonly used directly as a fuel for internal combustion engines.

Statement 2 states that green hydrogen can be blended with natural gas and used as fuel for heat or power generation. This statement is correct. Blending green hydrogen with natural gas can help reduce the carbon emissions associated with natural gas combustion, making it a cleaner fuel option for heat and power generation.

Statement 3 states that green hydrogen can be used in the hydrogen fuel cell to run vehicles. This statement is also correct. Hydrogen fuel cells convert the chemical energy of hydrogen into electricity, which can power electric vehicles. Green hydrogen can be used as a sustainable fuel source in hydrogen fuel cells, providing an alternative to traditional fossil fuel-powered vehicles.
