1.	hydrogen is considered as a future fuel mention advantage of hydrogen as a fuel ? ( 5 advantages max )
Answer» Advantages of hydrogen are: 1) It is not a POLLUTANT. Does not HARM the environment. 2) It has a high calorific value. 3) It does not produces residues like ASHES after burning. 4) When hydrogen burns, pollutants like CARBON dioxide are NOT produced. 5) Hydrogen is used in fusion - reactions of nuclear energy. The enormous heat so produced breaks the fused He nucleus into hydrogen atoms which again joins to form a He atom, releasing a lot of energy. In this way, the hydrogen atoms (or molecules) can create a LONG self-sustaining energy chains that would keep releasing large amounts of energy.
