Solar fuels such as hydrogen are being studied as sources of energy.All of the following statements about hydrogen as a fuel source are true EXCEPT
A)Fuels that are produced using sunlight as the energy source and water as the chemical feedstock are clean and renewable.
B)Solar-hydrogen systems use materials that are abundant and do not harm the environment.
C)Significant amounts of carbon dioxide would be emitted.
D)Solar-hydrogen systems rely on compounds that increase efficiency.

Question

Quizplus · Accepted Answer

Significant amounts of carbon dioxide would NOT be emitted by solar-hydrogen systems as hydrogen combustion produces only water as a byproduct, and the production of hydrogen through water splitting using renewable energy sources such as solar is considered as a clean process.
