Solar-electrocatalytic Fuels and Chemicals - The Science of turning free electrons into molecular bonds and back

Peter Strasser

Technische Universität Berlin, GER

Electrochemistry and Electrocatalysis play prominent roles in the science and technology of storing and converting free electrons from renewable sources into sustainable “solar fuels” and “solar chemicals”. Electrolyzers, photoelectrochemical cells, and fuel cells constitute components of future “E-refineries” that will make today’s fissile refineries obsolete and help close the global elemental H, C, O, and N cycles by means of circular economies. Storage and conversion of free electrons is put into effect via molecular bond making and breaking, catalyzed at electrified interfaces between an ion conductor and an electrocatalyst.

In this talk, I will first highlight the role of the Electrochemical Sciences within future renewable energy systems and will then discuss some advances in the design and understanding of nanostructured electrocatalytic materials 1 2 3 4 5 6 7 8 and their liquid-solid interfaces relevant for the electricity-based generation of power, energy fuels, and chemicals.

The electrocatalytic production and conversion of fuels/chemicals from and into electricity in electrolyzers and fuel cells depends critically on the availability of efficient catalysts.
