Abstract

Up to now CO₂ is considered as a waste which should be extracted from the atmosphere and stored in the ground (CCS). The European Parliament has already decided to initiate such a technique. In this paper we show that CARBON DIOXIDE can be considered as a RAW MATERIAL which can be processed into a chemical fuel, for example into methane or synfuel. This is a drastic change to the present views. The process is based on two steps: - reduction of water to generate hydrogen - reduction of carbon dioxide with the generated hydrogen in presence of adequate catalysts. This technique will allow a storage of electricity at large scale in a chemical fuel, which will become a necessity when the electric grid will integrate large amount of renewable energy sources (PV or wind).
