CUTECObjective

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

CUTECGEMIS

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

CUTECIntroduction 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

CUTECFeatures 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

CUTECBasics

Emission calculation Separate lecture

Climate change gases CO2 equivalent

CO2, CH4, N2O, refrigerants SO2 equivalent

Air emissionsOr individual figures

TOPP equivalentOzone precursor substances

CUTECMain elements

Whole chain Resource-Transport-Conversion-Final Energy kWh electricity or fuel

Technologies and sources as defined before

CUTECEnergy benefit ratio

kWh of fossil energy per 1 kWh of final energy Ratio of output energy / fossil input energy

CUTECOwn experience

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