17. EIfER 17 Biomass: GIS-based energy wood resource assessment in the northern Black Forest region (I) Study area and partners Black Forest 57% forest (mainly public) Source: http://www.nordschwarzwald-region.de/ The Forest State Administration (Landesforstverwaltung B.W.) The regional planning authority (Regionalverband NSW) University of Karlsruhe (EIfER, IPF) EDF

18. EIfER 18 Biomass: GIS-based energy wood resource assessment in the northern Black Forest region (II) Diameter of the tree (BHD) Production costs rise exponentially with smaller tree diameters Slope Applicability of highly automated machines is limited to max. 30% slope Tree species Wood energetic value depends on the tree species Transport distances Wood chip production chain and related cost factors

19. EIfER 19 Biomass: GIS-based energy wood resource assessment in the northern Black Forest region (III)  Model the theoretical potential  Model costs for wood chip production for each forest stand  Model transport costs Layers: - road network's nodes - forest plots - digital terrain model Methodology

20. EIfER 20 Biomass: GIS-based energy wood resource assessment in the northern Black Forest region (IV) Wood chip processing costs for each forest stand Show all forest stands that offer more than x tons dry mass/ha and where mobilization costs is less than y €/m³ Supply curves for scenarios with respect to several parameters Wood energy potential can be modeled as steady function of wood chip market price  supply curves Some results

22. EIfER 22 Geothermics: potential assessment of deep aquifers for power production in Alsace (I) F D EIfER BRGM Alsace ADEME ÉS Potential for geothermal power production depends on : - depth of the aquifer - temperature of the aquifer - thickness of the aquifer Study area and partners

23. EIfER 23 3437 TWh which is more than 250 times the annual electricity consumption in the region. Grande OolitheMuschelkalkBuntsandstein In practice, the accessible resource that can be extracted is only a part of the total resource. The ratio depends on the availability of fluids in the aquifers (expressed by the transmissivity of the aquifer) and the time during which the extraction can be economically carried out.

27. EIfER 27 Conclusion (I) Real world Analysis of data Decision making Data collection and management Strategic level multi-criteria geographical analysis = link between regional and local levels A regional opportunity study (e.g. renewable energy resources) can provide realistic potentials and localization recommendations directly usable for local feasibility studies. Every local detailed study can enrich the regional database.

28. EIfER 28 Conclusion (II) Energy planning at the regional level:  assessment of the potentials (RES, energy efficiency, …) using multi- criteria geographical analyses  modeling of energy flows and impacts of scenarios (derived from potentials) Benefits: facilitation of the implementation at the local level (feasibility information, best practices) improved orientation (modeling, prospective) possible definition of precise regional targets (monitoring)
