Realization of hydrogen economy with electrochemical energy devices

Hydrogen economy is the sustainable production and utilization of hydrogen and shifting to hydrogen economy has the potential to reduce the carbon footprint substantially. The production of hydrogen, the first part of hydrogen economy is typically achieved by electrochemical and photoelectrochemical water splitting reactions. These reactions are energy demanding catalytic reactions and enormous efforts are dedicated across the globe to invent new catalysts and combinations to reduce the overpotential to economically accessible levels
