Implementation of bio-CCS in biofuels production – IEA Bioenergy Task 33 special report

Aug 2018

This IEA Bioenergy Task 33 study aims to provide an initial overview of the potential of biomass and waste gasification to contribute to carbon capture and sequestration (CCS) through the assessment of two example scenarios. The selected study cases (600 MWth thermal input) represent two different routes to biofuels production via gasification which cover a relevant range of gasification technologies, biofuel products and CCS infrastructure conditions:

• Case 1: production of Fischer-Tropsch syncrude from high-temperature, entrained-flow gasification in Norway.

• Case 2: bio-SNG production from indirect gasification in The Netherlands.

The results show that the addition of CCS to a biofuel production value chain will roughly double the amount of mitigated CO2 in both value chains, from 0.6 to 1.1 Mton/y while the overall biofuel production costs increase by 10%.
