Which of the following option best describe the hydrogen economy?

Which of the following option best describe the hydrogen economy?

  • A. Using dihydrogen in an efficient manner
  • B. Dihydrogen is carried and stored in the form of liquid or gas
  • C. Addition of dihydrogen to the reactant
  • D. Both (a) and (b)

Step-by-step solution

The hydrogen economy encompasses the entire cycle of hydrogen production, storage, transport, and use as a clean energy carrier. Option A highlights efficient use, and option B covers essential storage and transport aspects; both are integral to the concept. Option C, 'addition of dihydrogen to the reactant,' is a specific chemical reaction (hydrogenation) and not a general description of the hydrogen economy. Therefore, combining A and B provides the best description.
