Lummus Technology’s ethanol-to-jet (ETJ) process has been selected by GPS Renewables for NTPC’s sustainable aviation fuel (SAF) project in Pudimadaka, Andhra Pradesh—marking the first commercial license of Lummus’ integrated ETJ technology. The platform is positioned to produce SAF while lowering capital and operating costs and reducing carbon intensity.

What opportunities and hurdles do you see for scaling ETJ-based SAF production across India’s aviation and biofuels sectors?

ETJ lives or dies on feedstock and hydrogen: what ethanol stream are they using in Andhra (molasses or grain) and where does the H2 for hydrotreating come from? If it’s steam methane reforming or coal-based, the CI could erase the headline gains; what CI per MJ are they actually guaranteeing?

ETJ’s carbon math hinges on hydrogen; if NTPC’s H2 is grey, the CI benefit evaporates. Also, oligomerization hates water and chlorides, so interlock ethanol dryness and denaturant spec and put in Cl/S guard beds, or your HMI will light up.
