Shell C&T to license CO2-conversion technology for Engie e-SAF project

This article was originally posted on Chemical Engineering Online.
Summary
Shell Catalysts & Technologies has signed a technology license agreement with Engie for the KerEAUzen project in France, which aims to produce synthetic aviation fuel (e-SAF) from captured biogenic CO2 and renewable (green) hydrogen. Under the deal, Shell C&T will license its Shell XTL Process to enable CO2-to-fuel conversion, supporting the scale-up of low-carbon jet fuel for aviation decarbonization.

What do you see as the biggest hurdle to scaling e-SAF—access to green H2 and biogenic CO2, production cost, certification, or long-term offtake commitments?

Curious what impurity specs you’re designing around for the biogenic CO2 and H2 streams - ppm limits on H2S, O2, and NOx/organics can make or break RWGS and FT catalyst life. Also, how will KerEAUzen meet ASTM D7566 aromatics requirements - co-processing for a BTX cut or relying on blend ratios with conventional kerosene while staying RFNBO-compliant?

Is XTL being fed via an RWGS step on the biogenic CO2, or are they going methanol-to-jet first? Those CO2 streams carry O2, amines, and trace H2S - what’s the impurity spec and how are they safeguarding FT/hydroprocessing catalysts and exchangers? And please tell me there’s a hard interlock on H2 shortfall to keep H2/CO in range and prevent carbon laydown.

Is Shell XTL here an FT-syncrude path (RWGS + FT) or a methanol-to-jet route? That choice drives aromatics content and blend limits, plus downstream handling like seal swell and need for static dissipator additive at terminals - how are they planning to keep ASTM D7566 specs tight if green H2 supply fluctuates?

Is the XTL path here RWGS + FT or MeOH-to-jet, and how are you planning to ride through H2 intermittency without thrashing the reactors? We learned the hard way on an FT pilot that a few ppm O2 and traces of amine/S from “biogenic CO2” will poison cobalt fast - what’s the CO2 impurity spec and buffering/guard-bed strategy to keep catalysts alive and the unit steady?
