The use of lignite for chemicals enables the integration of renewable energies! The use of lignite produces CO 2. Renewable energies show different capacities (wind, solar). How can excess energy be used? How can a lack of energy be balanced out? Examples: 1.) Inverse SOFC: Production of H 2 /CO from CO 2 and H 2 O Integration in methanol production Syngas chain and chemical usage is necessary 2.) Electrolysis of H 2 O: H 2 use for hydrogenation reactions e.g. aromatics to cycloalkanes 3.) Combined cycle produces electrical power if renewables are weak or it produces syngas in the case of a low electrical power demand Syngas chain and chemical usage is necessary page: 12
