Introduction
•
The current research was completed within the Baltic Sea Region
Programme 2007-2013 project Baltic Biogas Bus. With regards to
the project, Tartu City Government has agreed to buy (bio)gasfuelled busses and to build the needed infrastructure.
• So far the following studies have been conducted:
1) Feasibility study of CNG busses to be used in public transport
2) Study about the production of landfill gasses of Aardlapalu landfill
3) Study about the selection of locations for CNG fuelling stations
4) Feasibility study of a (bio)gas fuelling station
5) Feasibility study of the depot for biogas busses
The current study about the procurement options of CNG busses also
supports the cause of the project.

Introduction
The usage of CNG as fuel for vehicles
• Natural gas: the mixture of methane + ethane, propane,
buthane, fractions of higher hydrocarbons and inert gases
• Less polluting components deriving from combustion
• The preference of natural gas over liquid fuel prolongs the
working life of engines.
•
CNG can also comprise of biogas, which has been produced by
anaerobic decomposition in landfills, biogas generators and water
treatment plants, and which can be further purified to obtain
biomethane.

Introduction
The usage of CNG as fuel for vehicles
• Embodiments of CNG engines:
a) bifuelled engine, which is capable of using both natural gas and
benzine
b) two-system engine, in which the engine works only on diesel or the
combination of diesel and natural gas. The diesel part is used for
the ignition of natural gas.
c) single system engine, working only on natural gas (preferred by
the bus producers)
•25 per cent less CO2 production compared to petrol fuelled cars, 20
per cent less compared to diesel cars
• engine noise level 2 times lower.

Purpose of the study
•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

Methods
* To establish the best procurement choice, table comparison
has been used, in where the procurement conditions (total
price, delivery time, guarantee, passenger capacity) have
been indicated as “+” (favourable) and “-” (unfavourable).
Evaluation is based on the arithmetic mean of the procurement
conditions, which has been found by using the table calculation
program of MS Excel 2007. On the basis of the arithmetic
mean, the delivery conditions of the 5 suppliers have been
divided into criteria of pros and cons (“+” and “-”).

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.
