  1. GEMIS-TrainingBangkok, March 2012 Dipl.-Ing., M.sc.agr. Werner Siemers

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

  3. GEMIS • GEMIS = Global Emission-Model of Integrated Systems • Data bankapplication • Balance foranalysis/summaryandcomparison • Noproofforcorrectfigures • As withothersimulationsanddatabanks • Garbage in = garbage out

  4. Introduction LCA • Life-cycle-analysis ofenergy-, material- and transport-processes • Energyand material flowfromcradleto grave • Calculation, summingupanddescriptivefigures • Evaluation andcomparison • Analysis ofeffects • Here: emissionsfromproductorprocess • Inclusionofcostaspects

  5. Principle LCA

  6. 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

  7. Basics • Emission calculation • Separate lecture • Climatechangegases • CO2 equivalent • CO2, CH4, N2O, refrigerants • SO2 equivalent • Air emissions • Or individual figures • TOPP equivalent • Ozoneprecursorsubstances

  8. Main elements • Products • Energyresources • Completedata • Neededforexactemissioncalculation • Materials • Costsand environmental impact • Resources • Renewableand non-renewable • Emissions

  9. Processes • Examplecombustion • Connection toprocessenergydelivery • Definition ofefficiency • Main and additional products/by-products • Costs • White cellscanbeedited, greycellsarecalculatedby GEMIS • Calculationofemissions • Evaluation ofemissionreductionmeasures • ExampleEnergyconversion

  10. Resultsfromcalculation • Wholechain • Resource-Transport-Conversion-Final Energy • kWh electricityorfuel • Technologies andsourcesasdefinedbefore

  11. Energybenefitratio • kWh of fossil energy per 1 kWh of final energy • Ratio ofoutputenergy / fossil inputenergy

  12. Scenarios • Comparisonofenergydemand • Comparisonofoptions • More features • Export ofdata • Explanations • Global switch • Scopeofanalysis • Allocations

  13. Ownexperience • A bittricky • Do not believeandre-calculate/estimate • Input andoutput in additional excelsheets • Effort, allocate time andconcentration
