Sustainable aviation fuel from direct CO2 capture and green hydrogen

Project: Experimental Development/Translation Research

Project Details

Abstract

Alternative fuels, such as sustainable natural gas and green hydrogen are gradually replacing the fossil-based fuels in automotive and maritime transportation. To find a similar substitute for the aviation industry has been challenging, aircrafts are still powered by fossil-based kerosene. Sustainable aviation fuels (SAF), which derive carbon feedstock from either biomass, sustainable methane, or carbon dioxide, are the only realistic alternatives. However, the most realistic source of carbon for the world-scale production of SAF is via CO2. The production of (MeOH)/ (DME) from CO2 is one of the most mature technologies for CO2 utilization, the alcohol conversion to jet fuel is a multi-stage technology. In the conventional route, at least two steps. However, there is an attractive opportunity to reduce the number of transformation steps by reacting DME directly with the fossil-cut, a step that has the capacity to reduce OPEX and CAPEX of the process. In this study, we plan to develop the LCA and the techno-economics of newly developed SAF, which involves the analysis of using direct air capture of CO2 as a feedstock, methane pyrolysis, and then compare the newly developed with conventional SAF production routes.
