Question
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?1 point(a) Only one(b) Only two(c) All three(d) None
Solution
To determine how many of the statements are correct, let's evaluate each statement one by one:
-
It can be used directly as a fuel for internal combustion. This statement is incorrect. Green hydrogen cannot be used directly as a fuel for internal combustion engines. It needs to be converted into a usable form, such as being used in a fuel cell or blended with other fuels.
-
It can be blended with natural gas and used as fuel for heat or power generation. This statement is correct. Green hydrogen can be blended with natural gas and used as a fuel for heat or power generation. This blend is known as "hydrogen-enriched natural gas" and can be used in existing natural gas infrastructure.
-
It can be used in the hydrogen fuel cell to run vehicles. This statement is also correct. Green hydrogen can be used in hydrogen fuel cells to power vehicles. The fuel cell combines hydrogen with oxygen from the air to produce electricity, which can then be used to power electric motors in vehicles.
Based on the evaluation of each statement, we can conclude that two of the statements are correct. Therefore, the answer is (b) Only two.
