New Solar-Powered Paint can Produce Hydrogen as a Clean Energy Source

In science's quest to develop less polluting sources of energy, hydrogen gas has often been used as an example as a potential replacement for fossil fuels: aside from being the most abundant substance in the universe, it is also the most combustible natural substance known, and only produces pure water when burned with oxygen. Unfortunately, the chemical instability of its gaseous form means that storing it is inherently hazardous, and the extraction of the gas from hydrogen's more stable forms, such as water or petroleum products, can be highly energy inefficient, or produce a disproportionate amount of waste pollutants.
