Hydrogen is a clean energy carrier and potentially major solution to the problems of climate change and depletion of conventional fuels. Hydrogen is safer than gasoline, diesel and other non-renewable energy sources. It could eliminate dependence on imported fuels. Also, it can potentially solve intermittency problems of solar and wind energy, by storing energy in the form of hydrogen, and later converting back to electricity via fuel cells when needed. As a mass-scale carrier of energy, hydrogen use would protect the environment for future generations, by reducing and eliminating greenhouse gas emissions and pollution from fossil fuels. Through innovative research at CERL, it can become economically competitive with other conventional fuels.
