A previous study in 2009 considered a number of different transport modes and their suitability for use in the Leeds context, identifying a short list of three transit modes: a tram, a trolleybus or a high-specification bus. Subsequent work confirmed that a tram was not affordable within the funding envelope and thus not deliverable. Since 2009 there have been significant developments in bus propulsion technology. These include a widespread uptake of hybrid buses, the deployment of small numbers of battery electric buses and projects to demonstrate more novel technologies such as fuel cell buses. There has also been a trend of technology convergence leading to developments such as fast charging ‘plug-in’ hybrid buses which can operate for some distance on battery power and electric buses which can recharge inductively or from short sections of overhead line equipment (OLE). The purpose of this investigation is to update the previous work and fully assess these emerging technologies to ensure that the sub mode selected for the NGT project is suitable and meets the scheme objectives. The assessment considers capital costs, life cycle costs, environmental, sustainability and health impacts. The key output of the study is a new shortlist of sub modes from a technical perspective, with supporting evidence. The conclusions of this report feed into the assessment of Alternative options for the NGT scheme, which has been undertaken by Steer Davies Gleave. The sub modes investigated in this study are: ° Trolleybus (with OLE); ° Catenary Free Electric Bus; ° Standard diesel hybrid; ° Plug-in diesel hybrid; ° Fuel cell hybrid; ° Battery electric; and ° Compressed Natural Gas (CNG) bus powered by biomethane from waste. Conclusions The study concludes that fuel cell hybrid, battery electric and CNG buses should be rejected as sub mode options for NGT on the following grounds: ° Fuel cell hybrid - cost and technology risk; ° Battery electric - insufficient range and capacity of the current generation
