A full switch from fossil LPG to biopropane for the UK market by 2040 is considered feasible by NNFCC and this document outlines in more detail the possible pathway as well as providing information about biopropane and its advantages for homes and businesses.
Most biopropane is produced as a co-product of the hydrogenated Vegetable oil (HVO) process, where vegetable oils are treated with hydrogen to produce renewable diesel or aviation oil. HVO and co-processing are likely to be the main source of biopropane during the next decade, however after that gasification and Fischer-Tropsch synthesis is likely to be the dominant production technology. For this a variety of feedstocks including lignocellulosic biomass, sugar, starch, waste and glycerol are processed in a variety of ways in order to produce biopropane.
