Abstract

The past few decades have witnessed a global search for clean and renewable energy sources, such as hydrogen (H₂). Hydrogen benefits from a relatively high energy density and has already found successful applications in fuel cells and combustion processes, through its green exothermic reaction with oxygen (O₂). The large, and growing global demand for H₂ is currently met mostly by methane reforming, a process that requires a high energy input and thus typically requiring an extensive use of fossil fuels. Sustainable methods for large scale production of hydrogen are then needed with high urgency.
