CUTEC Objective What is GEMIS What GEMIS delivers How to operate GEMIS Examples Tips and Tricks, Q&A

CUTEC GEMIS GEMIS = Global Emission-Model of Integrated Systems Data bank application Balance for analysis/summary and comparison No proof for correct figures As with other simulations and data banks Garbage in = garbage out

CUTEC Introduction LCA Life-cycle-analysis of energy-, material- and transport-processes Energy and material flow from cradle to grave Calculation, summing up and descriptive figures Evaluation and comparison Analysis of effects Here: emissions from product or process Inclusion of cost aspects

CUTEC Principle LCA

CUTEC Features of GEMIS GEMIS assesses the final utilization based on the used resources Calculation of life cycles incl. construction and disposal (if wanted) Including transport, process energy, support energy, materials etc. Project „Standard“ contains checked figures Own processes to add or look up known processes Problem: non-linear relations, loops

CUTEC Basics Emission calculation Separate lecture Climate change gases CO2 equivalent  CO2, CH4, N2O, refrigerants SO2 equivalent  Air emissions  Or individual figures TOPP equivalent  Ozone precursor substances

CUTEC Main elements Products Energy resources  Complete data  Needed for exact emission calculation Materials  Costs and environmental impact Resources  Renewable and non-renewable Emissions

CUTEC

CUTEC Processes Example combustion  Connection to process energy delivery  Definition of efficiency  Main and additional products/by-products  Costs  White cells can be edited, grey cells are calculated by GEMIS  Calculation of emissions  Evaluation of emission reduction measures Example Energy conversion

CUTEC

CUTEC

CUTEC Results from calculation Whole chain  Resource-Transport-Conversion-Final Energy  kWh electricity or fuel Technologies and sources as defined before

CUTEC Energy benefit ratio kWh of fossil energy per 1 kWh of final energy Ratio of output energy / fossil input energy

CUTEC Scenarios  Comparison of energy demand  Comparison of options More features Export of data Explanations Global switch  Scope of analysis Allocations

CUTEC Own experience A bit tricky Do not believe and re-calculate/estimate Input and output in additional excel sheets Effort, allocate time and concentration
