LCA analysis in CO2-to-carbonates technologies
The use of carbon dioxide as chemical building block has the chance to mitigate CO2-emissions from power plants and large industrial sites. Furthermore, the use of CO2 as a C1-building block can help to overcome the dependency on fossil fuels for these buildings blocks. To allow a correct comparison of the new reactions, it is essential to choose the benchmark for the new process correctly (Scheme 1). To enable an early estimation for the global warming potential of a new reaction, Evonik established the Carbon-Footprint-Estimation tool.
Scheme 1: Life cycle of a new product in comparison to the benchmark.
In the public-funded project1 H2ECO2 the consortium attached to the Science-to-Business Center Eco² of Creavis developed a cascaded method for the thermodynamic, ecological, economical analysis and catalytic and process feasibility of new processes based on CO2. Industrial relevant target molecules have been identified with a great CO2-saving potential. Suitable catalysts and a synthetic route have been designed and a life cycle analysis for the new product has been completed.
 This project is funded by the German state of North Rhine-Westphalia (Ministry for innovation, science and research) and co-financed by the EU (European Regional Development Fund).
