CNG Bus Procurement Options Research in Baltic Biogas Bus Project

This research delves into the procurement options for CNG buses in the Baltic Biogas Bus Project within the Baltic Sea Region Programme. It evaluates the feasibility and benefits of using CNG as a fuel for public transport vehicles, comparing CNG buses' technical specifications and procurement conditions from different suppliers to determine the most favorable choices. The study aims to support the project's cause by providing insights and recommendations for selecting the best suppliers based on factors like total price, delivery time, guarantee, and passenger capacity. Detailed findings, evaluations, and recommendations are presented for both 12m and 18m CNG buses to assist in making informed decisions. Visit www.balticbiogasbus.eu for more information.

  3. Introduction • Thecurrentresearchwascompletedwithinthe Baltic Sea Region Programme 2007-2013 project Baltic BiogasBus. Withregardstotheproject, Tartu City Governmenthasagreedtobuy (bio)gas-fuelledbusses and tobuildtheneededinfrastructure. • Sofarthefollowingstudieshavebeenconducted: • 1) Feasibilitystudyof CNG bussestobeusedinpublic transport • 2) Studyabouttheproductionoflandfillgassesof Aardlapalu landfill • 3) Studyabouttheselectionoflocationsfor CNG fuellingstations • 4) Feasibilitystudyof a (bio)gasfuellingstation • 5) Feasibilitystudyofthedepotforbiogasbusses • Thecurrentstudyabouttheprocurementoptionsof CNG bussesalsosupportsthecauseoftheproject. www.balticbiogasbus.eu

  6. Purposeofthestudy • To analyse and compare CNG busses and their procurement conditions meant for serving in the public transport, having sent inquiries to different bus producers/suppliers www.balticbiogasbus.eu

  7. Methods * Toestablishthebestprocurementchoice, tablecomparisonhasbeenused, inwheretheprocurementconditions (totalprice, deliverytime, guarantee, passengercapacity) havebeenindicatedas “+” (favourable) and “-” (unfavourable). Evaluationisbased on thearithmeticmeanoftheprocurementconditions, whichhasbeenfoundbyusingthetablecalculationprogramof MS Excel 2007. On thebasisofthearithmeticmean, thedeliveryconditionsofthe 5 suppliershavebeendividedintocriteriaofpros and cons (“+” and “-”). www.balticbiogasbus.eu

  8. Methods Priceinquirieswere sent tothefollowingenterprises: 1. Keil M.A. OÜ 2. Solaris Bus & Coach S.A 3. AS Silberauto 4. Scania Eesti AS 5. TEDOM s.r.o. (TEDOM Holding company) www.balticbiogasbus.eu

  9. Results - Comparision of CNG busses technical specifications – 12m length www.balticbiogasbus.eu

  10. Results - Comparision of CNG busses technical specifications – 18m length www.balticbiogasbus.eu

  11. Results– Comparison of CNG buses procurement options – 12 m busses www.balticbiogasbus.eu

  12. Results– Comparison of CNG buses procurement options – 18 m busses www.balticbiogasbus.eu

  13. Evaluationcriteria www.balticbiogasbus.eu

  14. Summary and recommendations Feasible options of procurements 12m CNG busses – Mercedes-Benz Citaro CNG and TEDOM C12G. 18m CNG busses – Mercedes-Benz Citaro CNG. Recommendations: *Find more info about technical properties of the busses, especially regarding the concrete solutions and Tartu city features. *More research needed about specific delivery and payment conditions. *Start negotiations with the most suitable supplier in order to sign contracts. *After the project´s preparatory phase, start the pilot project. www.balticbiogasbus.eu
