Flexibility in biomass related energy conversions
Liquid Fuels (MeOH, FT, …)
Methane, LNG,Methane & CO2
H2
Pyrolysis oil
Producer gas
Biogas
Feedstocks Application (variable)
CO2 for BECCS
Transport & Mobility
Chemical Industry
Heat (storage) & electricity(FCs, ICE, mGT)
Dry biomass(storable)
Wet biomass(usually not storable)
Renewable electricity (variable)

Pellets, Chips
Stabil. Pyrolysis oil
Energy carrier(storable, large spatial and
temporal flexibility)
Intermediates(limited spatial and
temporal flexibility)
Heat
