Hydrogen Energy by Means of Proton Conductors

Abstract

If we dare to take serious what we know today about climate issues the challenges to our energy systems are immense. If we really chose - also in practice - to phase out the fossil fuels major changes to the way we handle energy are required. The renewable energy resources are by far sufficient, but matching supply and demand in time as well as in form calls for new engineering solutions. Hydrogen as energy carrier and energy storage medium has often been mentioned as an option for the future. A protons is an elementary particles, but at the same time the ion of hydrogen. When hydrogen (H2) is extracted from water (H2O) it can happen via formation of protons (hydrogen ions, H+) which must be transported away by proton conducting materials to form molecular hydrogen (H2). This process is called electrolysis and converts electrical energy into the chemical energy of a fuel. The reverse process of making electricity from a fuel takes place in a fuel cell. The talk will present different aspects of the concept of hydrogen energy and how materials science can bring this technology of the future closer to the present.
