analysis

and adds any further analysis
needed in relation to imports, exports, transport/distribution
infrastructure and cross-sector linkages. The mapping exercise
could be qualitative or quantitative; the purpose is to provide a
clearer picture of bioenergy application priorities in relation to the
expected evolution of sector demands.
Figure 6 shows an example for mapping key demand sectors
into priorities for bioenergy end-uses and applications. The goal
here is to insure that policy objectives and bioenergy priorities
are realistic in relation to current and expected demand across
sectors. If suffcient data and modelling expertise exists, various
scenarios
<Mod3-Implementation>
could be used to examine the
implications of various bioenergy expansion paths for the future
demand structure and energy mix.
What? – Feedstocks and Technologies
In the previous step
<Which?>
,
the sector and end-use priorities
for bioenergy were established by drawing on the basic policy
objectives
<Why?>
and the overall energy demand/supply
requirements and constraints across different sectors. In some
cases, specifc targets, fuel shares and climate reduction
goals may have been attached to the bioenergy pathways that
emerged. The next step is to determine
what
feedstocks and
technology conversion platforms should be pursued to meet
these targets in a cost-effective and sustainable manner. The
determination of a set of feedstocks and technology options
can be further broken down into six steps as shown in Figure
7. Some defnitions and examples are provided below for each
step. The steps generally follow the basic elements of the
bioenergy production chain
<Mod1-Techno-economic>
that
defnes bioenergy system boundaries. It should be noted that the
choice of feedstocks will have signifcant implications for the use
of resources (land, water, fertilisers); however, in order to provide
