Hi Somasis
Summarise your introduction, it should be of one short paragraph.
In the advantages , you can write that hydrogen powered vehicles do not need to be plugged in for charging, like battery-powered EVs and there is a wide availability of resources for producing hydrogen.
In the challenges , you have written good points. You can also add that handling of hydrogen is a safety concern because it is more explosive than petrol.
Good conclusion.
Try giving subheadings.
Work on handwriting !

Hi Divya
Good introduction but club the two paragraphs in one.
All points are good in advantages part except one, you have written that that it can be used in rockets, it is irrelevant, instead of it, you can write that hydrogen powered vehicles do not need to be plugged in for charging, like battery-powered EVs .
Challenges are discussed in a comprehensive manner, try giving subheadings.
Good conclusion.
Underline keywords.
Keep working hard.
