T697: Investigation into the use of bio-diesel fuel on Britain’s railways

Topic

Energy

Description

This project will investigate the feasibility of using bio-diesel on British rolling stock through a desk top study, engine bed-tests and in-service trials.

Abstract

Over the next decade, the rail industry has an opportunity to further improve its environmental performance in relation to other transport sectors by moving to greener fuels. In the short term, the benefits of sulphur free diesel are being demonstrated by R&D project T536 ‘Investigation into the use of sulphur free diesel on railway vehicles’. Other potential fuels are on the horizon and are being investigated by other transport sectors. Over the next few years road diesel will change to incorporate 5% bio-diesel (sourced from sustainable crops) and there is discussion about higher blends. There may be benefits to the rail industry and to the environment if rail were to follow suit. Working with ATOC and the Biodiesel Working Group, the aim of this project is to trial the use of bio-diesel in order to establish the advantages and disadvantages associated with its use. The project has completed a desk-top review and is now delivering a programme of test-bed trials prior to in-service trials if warranted.
