Impact Pathway Approach for Sustainable Energy Systems

This study explores physical impacts, emissions, and monetary evaluation of sustainable energy projects via a dual calculation method. The analysis covers emissions from transportation and chemical processes, aiming to derive general answers for policy questions. The approach emphasizes country-specific damage factors for accuracy and applicability, utilizing regional atmospheric dispersion modeling. The research presents Source-Receptor matrices and cost assessments for different pollutants, highlighting the cost-effectiveness of sustainable energy solutions.

  1. Generalisation & Aggregation SIXTH FRAMEWORK PROGRAMME [6.1] [ Sustainable Energy Systems] Philipp PREISS Universitaet Stuttgart Brussels, February 17, 2009

  2. Impact Pathway Approach Differences of Physical Impacts Emissions MonetaryEvaluation Calculation is made twice: with and without project! Physical Impacts Transport and chemical Transformation

  3. Ideally, site specific marginal damage costs are calculated However, Policy questions need more general answers, such as,external costs per kWh from coal fired power stations, i.e.an average for country or EU Input data is not site specific, for example, emissions from up- and downstream processes for construction of photovoltaic Damage factors, such as [Euro per tonne SO2] are needed as input for different models (energy, economic, etc.) Sophisticated dispersions models are costly in CPU time Solution:  Site dependent, i.e. country specific damage factors Trade-off: Accuracy vs. Applicability

  4. Regional Atmospheric Dispersion Modelling Regional modelling with EMEP/MSC-West Eulerian dispersion model from MET.NO  Source-Receptor (SR)-matrices for EU27 + 12 + 5 maritime divided in 66 sub-regions - 5different meteorological years  averaging the results- 2 different background scenarios = present & future emissions - emissions form all sources and high stacks separately Example: one SR-matrix:  due to 15% emission reduction of SO2 in one region concentration increment prim. and sec. pollutant in each 50 x 50 km grid cell  delta concentration per unit of emission  Generalisation & Aggregation [Euro per tonne]

  5. -15% NOx in sub-region 4,d &... & -15% xyin sub-region i,j ………. Sketch Source Receptor Matrices Approach ΔConc.ozone ΔConc. sulphates Background Emissions (SO2, NOx, NH3, NMVOC)grid for Europe ca. 50km * 50km -15% SO2 in sub-region 4,d &... &

  6. SR-matrices for 66 sub-regions

  7. Prim. & sec. pollutants [µg/m3] [mg / m2] [ppb*day]

  8. Example for Sulphates Exposure due to 1 t SO2 Emission in S-Germany  AccExp SO42-[pers * µg/m³]  0.16 YOLL ca. 6,400 Euro

  9. Euro per Tonne (all sectors) in 2025 (selected countries)
