Biomethane as a fuel for city transport

Depletion of fossil energy sources, and thus the prices increase of conventional fuels such as gasoline or diesel fuel, the energy security and dependence on imported fuels, as well as the deteriorating environment and global warming mean that there are more and more new technologies using renewable energy sources nowadays. In the medium- and long-term perspective a significant changes are needed regarding means of transport in ensuring "sustainable mobility", while the horizon of short-term solution is the implementation of biofuels, including biogas refined to form of biomethane, and renewable alternative fuels. Biomethane is produced from waste organic matter. Directive 2009/28/EC indicates the benefits of using waste for the production of transport fuels, to decarbonisation of the energy sector and requires Member States of UE to use renewable fuels. The paper presents possibilities for the biomethane production, as well as conditions to use it as fuel to power city buses. The level of current use of gaseous fuels in the national urban transport was specified, and also conducted an evaluation of benefits, especially ecological, to use these fuels for these applications.
