Gas geven - gas nemen : een witboek over twee praktijkproeven met aardgas als motorbrandstof in het openbaar vervoer + bijlagen. Onderzoek in het kader van het Programma Rationeel gebruik van energie in Verkeer en Vervoer REV.

This report presents the results of two tests in practice with natural gas as the fuel for buses in public transport. In the first test seven buses were used in the cities of Groningen, Rotterdam and The Hague. In the second test nine buses were used in the region of Utrecht. All buses were propulsed by natural gas. The aim of the tests were to study which technical problems arised when these buses were used in practise and to get information on benefits for the environment and on the financial and economic realization. For some of the relevant papers given in part b see C 3486 - C 3488.
