The BioGrace II tool
General approach and structure
Public workshop
30 October 2013, Brussels Slide 2
Directory
• Easy direction to other sheets
• One calculation sheet per pathway
• Additional sheets:
• LUC
• esca
• N2O field emissions
• Standard values
• Final conversion only
Example: Wood pellets from forestry residues
Public workshop
30 October 2013, Brussels Slide 3
Steps from cultivation to final energy
esca: methodology still
under discussion
eu: maybe relevant for biogas pathways
eec, ep, etd = basic „disaggregated default values“
el: following the decision 2010/335/EU
eeccs/ccr: technology not in place
Public workshop

General structure
I. Overview results
II. General settings
III. Calculation per
phase
Public workshop

I. Overview results
Energy carrier Final energy
Indication of actual
and default values
Public workshop

I. Overview results
Energy carrier Final energy
Final conversion based on
actual efficiency
Public workshop
30 October 2013, Brussels Slide 7
I. Overview results
Allocation factors and references
Allocation of electricity
and heat (CHP) according
to Carnot efficiency:
Allocation of by-products
and main products in
production chain: lower
heating value
Public workshop

II. General settings
Without filling this in,
NO GHG emissions
reductions will be
calculated !
Public workshop
30 October 2013, Brussels Slide 9
When actual calculations are done: • The Biograce rules must be followed
• Track changes must be switched on:
- Highlights all changes
- Shows editor’s name and old values in the comment field
II. General settings
Public workshop

III. Calculation per phase – Cultivation eec
fill in actual data
Yield related
conversion factors
multiplying input values
with “standard values“

III. Calculation per phase – Cultivation eec
Results related to different units

III. Calculation per phase – Processing ep
fill in actual data
conversion factors
yield related
Public workshop

yield related conversion factors: raw material per final biofuel
values as a function of input values
and/or of the chain
