Evaluation of viable transportation options. Carbon Capture technology Reservation of sufficient area on the site for the later retrofit of the CO 2 capture unit with CO 2 compression, for all plant integration measures and for retrofit-construction period. Assessment of the economic and technical aspects for the later retrofit and integration of the CO 2 capture unit different options for the respective retrofit strategies. Selection of best-available-capture-technology, capture ready concepts for technology routes are deviant.
