Abstract
Potential to increase biofuels output from a
gasification-based biorefinery using external hydrogen
supply (enhancement) was investigated. Up to 2.6 or
3.1-fold increase in biofuel output could be attained for
gasoline or methane production over reference plant
configurations, respectively. Such enhanced process
designs become economically attractive over non-enhanced
designs when the average cost of low-carbon hydrogen
falls below 2.2-2.8 /kg, depending on the process
configuration. If all sustainably available wastes and
residues in the European Union (197 Mt/a) were collected
and converted only to biofuels, using maximal hydrogen
enhancement, the daily production would amount to 1.8-2.8
million oil equivalent barrels. This total supply of
hydrogen enhanced biofuels could displace up to 41-63 per
cent of the EU (European Union)'s road transport fuel
demand in 2030, again depending on the choice of process
design.
