Abstract: The LPG industry, with current global consumption of some 300 million tonnes per year, is faced with decarbonising its product, as is the rest of the fossil fuel sector. Research has identified eight potential pathways to renewable LPG (RLPG): so far only one of them is commercial. This lecture presents an analysis and ranking of the eight pathways. The most-promising are: HVO, which is already commercial; gasification of biomass; and oligomerisation of olefins (alcohol-to-jet).
