Abstract: The atmospheric carbon dioxide concentration and the global land-water temperature increased steadily during the last decades. There is little doubt that the temperature rise is mainly caused by the growing carbon dioxide emissions. Dramatic consequences for life on earth are foreseen, if the temperature rise continues at the same rate for the next 50 years. Therefore hundreds of millions of dollars have been invested during the last 10 years for the development of technologies to capture carbon dioxide from air and from electrical power plants exhaust gas.
Using basic thermodynamics this lecture will show that most claims made about carbon capture are highly questionable. In spite of many promises carbon capture from air but also from coal-fired power plants will not help to slow down the alarming increase of atmospheric carbon dioxide concentration. Carbon Capture and Storage (CCS) is often used just as an alibi to continue the operation of coal-fired power plants. CCS may be seen as boondoggle, an activity that is pointless, but gives the appearance of having value. Meaningful alternatives to CCS are energy conservation, investment in renewables and “green engineering” (replacement of traditional separation and reaction designs by energy saving schemes).
Biography: Klaus-V. Peinemann has more than 30 years experience in the field of membrane research (academic and industrial). He coordinated a number of European and German national membrane projects. From 2002 to 2004 Peinemann served as President of the European Membrane Society and he is a co-founder of GMT Membrantechnik GmbH in Germany, which is now a leading company in Europe for the production of membranes for gas and vapor separation. Peinemann is since 2011 Professor of Chemical Engineering at KAUST. His research interests are: Multicomponent polymer-based membranes for liquid and gas separation; novel membrane preparation methods; solvent-stable membranes for nanofiltration/reverse osmosis; self-assembled block copolymer membranes; Peinemann published numerous papers in high ranking journals including work on CO2-selective membranes; citation index: https://scholar.google.com/citations?user=aHo13voAAAAJ&hl=en
