With the aim to reduce the CO2 footprint, as proposed and enforced by policy makers in order to reduce the anthropogenic effects on the climate,
CO2 hydrogenation towards fuel production is a way to recycle this greenhouse gas and store abundant renewable energy. E.g. Iceland and
even regions in Germany have methanation plants in operation for this purpose. Switzerland has a vast surplus of hydroelectricity on one hand. On the other hand, companies in Switzerland will pay CHF 25 for every ton of carbon dioxide they produce. This is a strong motivation to find ways of fixing carbon dioxide and produce the anticipated products, e.g. formic acid,
methanol and hydrocarbons. The catalytic and electrocatalytic reduction of CO2 to form either syngas or hydrocarbons are highly challenging processes with respect to catalyst activity and selectivity.
This project will mainly focus on the development of advanced catalysts within the timeframe of this SCCER. In addition, the demonstration the feasibility of the processes on the laboratory scale reactor level (for catalytic CO2 reduction) and on the full cell level (the electro catalytic CO2 reduction,
also called co-electrolysis) with an efficiency of >30% and with a selectivity of >60% for syngas/hydrocarbons is planned.
