MOTIVATION and AIM
Motivation and background:
Biomass may be an important key to get to net zero
GHG emissions.
- Replace fossil fuels for vehicles, space heading,
industry and , electricity&DH production as well as
- Replace energy-intensive materials (such as
cement in buildings) and oil-products.
The question is where and how biomass reduces CO2 to
the lowest cost? E.g. assessed by a national TIMES model.
Difficult to get the numbers correct when biomass is not
one unique commodity with a straight flow throughout
the reference energy system.

Aim:
To create a ‘Reference Energy System’ of biomass flows

Flows of Woody Biomass in TIMES-Sweden
A biomass reference energy system
Conditions
 Biomass is not a uniform commodity.
 Competition of biomass also
between biomass as material and
biomass as energy source.
 The biomass potential from forest is
driven by the demand for ‘timber’.
 If biomass bi-products is withdrawn
from an industry, additional energy
sources may be needed.
 Coherence between results and
statistics.
Modell structure should capture
 Different fractions based on source
and on possibility for use.
 Primary commodity should be able to
‘deliver’ both material and energy
commodities.
 Link potential of forestry biomass to
use of ‘round wood’/’timber’.
 Bi-product: capture the difference IF
the bi-product is ’exported’ from the
industry OR used within the industry.
 In line with statistics and avoid
double counting -> Naming
