GEMIS-Training Bangkok, March 2012

This training session conducted in March 2012 by Dipl.-Ing. M.Sc. agr. Werner Siemers provides an extensive overview of GEMIS, the Global Emission Model of Integrated Systems. Participants will learn about the operational functionalities of GEMIS, including its application for life-cycle analysis (LCA) of energy, materials, and transport processes. The session covers emission calculations, evaluation methods, and practical examples, alongside tips and tricks for effective use. Attendees are encouraged to engage in Q&A and share their experiences for a comprehensive understanding of this tool.

  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
