Detailed explanation-1: -It is inexpensive to produce. The answer is D.
Detailed explanation-2: -Disadvantages of hydrogen energy source are as follows; Hydrogen being a rich source of energy is highly volatile and flammable in nature. So, it makes it risky. Hydrogen is not a cost-effective source of energy.
Detailed explanation-3: -Hydrogen is a highly inflammable substance and explosive in nature; it cannot be easily transported from one place to another and it can be generated by the hydrolysis of water but it is a very expensive process.
Detailed explanation-4: -Hydrogen has a high calorific value which means a large amount of heat is produced by burning 1 gram of fuel. So we’ll need lesser amounts to power similar energy requirements. No harmful gases are evolved during the combustion of hydrogen, thus making it environment friendly.
Detailed explanation-5: -Hydrogen can be produced from diverse domestic resources with the potential for near-zero greenhouse gas emissions. Once produced, hydrogen generates electrical power in a fuel cell, emitting only water vapor and warm air. It holds promise for growth in both the stationary and transportation energy sectors.
