Thermochemical and Bioinspired Production of Solar Fuel
Anthropogenic carbon dioxide emissions reach about 30 gigaton per year. CO2 is known to be a greenhouse gas and partly responsible for global climate change. Society, enterprises, governmental and non-governmental institutions are sensible to this fact and are working to find remediation to the global challenge of reducing CO2 emissions.
CO2 capture, storage and utilization (CCSU) technologies are becoming more and more available, but it most cases there are still societal and economic hurdles. Leading companies see this situation as a potential business opportunity and are working in order to take competitive advantage by introducing new products and new technologies to transform CO2 into added-value products, and to capture and store CO2 in geological reservoirs. All these technologies, however, need to be cost-effective since enterprises need to respond to both its stakeholders and shareholders.
Total, one of the top five multinational oil and gas private majors, is working through the whole technology chain of CCSU with projects in CO2 capture and storage and projects in CO2 utilization. An analysis of the potential routes of transformation of CO2 led Total to focus on organic carbonates, since organic carbonates and in particular dimethyl and diethyl carbonate have been repeatedly reported as good performing oxygenate additive for transportation fuels.
This presentation aims at providing the CO2 scientific community with a clear exposition of the pros and the cons of organic carbonates as oxygenate molecules for blending in the fuel pool.
