Techno-economic and environmental assessment of CCU options

Abstract

If the transport sector, especially aviation, shipping and heavy load, will continue to rely on liquid fuels, carbon-based fuels might be unavoidable for the foreseeable time. With countless options of sustainable fuels, feedstocks and production routes, its difficult to determine preferences of one over the others. We present a methodology to assess these options fair and transparent simultaneously technically, economically as well as environmentally for comparison and selection. Because aviation is one of the fastest growing sectors in terms of CO2 emissions, the regulatory initiative ReFuelEU Aviation was introduced to mitigate the impact of aviation on the environment. Significantly reduced GHG emissions and lower abatement costs require technological innovations of Power-to-liquids, Biomass-to-liquids and Power enhanced Biomass-to-liquids processes. A detailed discussion of sustainable aviation fuels prospects will be presented. The methodology of techno-economic and environmental assessment will be applied to other transport applications and industry decarbonization efforts as well to address all sectors contribution towards Fit-for-55.
