  • 1. New Zealand Rail 2014 Auckland, 18 June 2014 Andreas Hoffrichter, PhD with material from Stephen Kent Supervisors: Stuart Hillmansen and Clive Roberts Hydrogen for Railway Propulsion
  • 2. Outline • Background • UK Technical Railway Strategy • Need for autonomous traction • Hydrogen as an energy carrier for railway propulsion • Hydrogen Pioneer prototype locomotive • Conceptual design of a regional train • Future work at the BCRRE • Hydrail developments in other parts of the world
  • 3.

  • 7. The Resurgent UK Railway • Resurgence of demand for rail in the UK: – growth in passenger numbers1 – freight also increasing, particularly containers1 • Drive to electrify: – increase capacity – supply power directly to point of use – not dependent on fossil fuels – legislation to cut emissions [1] Figures from Office of Rail Regulation
  • 8. UK Rail Technical Strategy http://www.futurerailway.org/RTS/Vision/Pages/On-Video.aspx
  • 9. Drive for Electrification • UK has less electrification than most of Europe, but catching up: – currently around 40% electrified – plans to increase to 51% over next 5 years • But cannot electrify everywhere: – not economically viable / affordable for rural lines – overhead wires not attractive and add complexity • UK will continue to need autonomous power & rely on diesel for time being: – unlikely train leasing companies will buy new DMUs – but cascaded diesel rolling stock will help
  • 10. Autonomous Options for the UK • Battery / battery-hybrid by Network Rail & Bombardier: – currently converting Class 379 multiple unit – test various battery types & configurations – pantograph backup • Dual mode by Hitachi: – IEP Class 800 – pantograph & under floor diesel generator • Hydrogen by University of Birmingham Source: Wiki Commons Source: Wikipedia
  • 11. Hydrail at University of Birmingham • Well-to-wheel analysis to evaluate general benefit • Construct and test prototype locomotive • Prove theoretical viability of hydrogen-powered regional train (100 km/h multiple unit) • Promote and support the development of a “real- world” application • Provide hybrid drive test facility to support development of future railway applications
  • 12. Well-to-Wheel Analysis • Analysis of “well-to-wheel” efficiency and CO2 output of various traction options • Looked at electric traction based on UK generation mix, USA and California (high proportion of renewables) • Railway traction / locomotive efficiency is highly dependent on load and duty cycle – assumed maximum vehicle efficiencies for study • Assumes H2 generated from natural gas & then: – stored as a gas or stored as a liquid – used in fuel cell or in a combustion engine Hoffrichter, A., Miller, A., R., Hillmansen, S., & Roberts, C. (2012). Well-to-Wheel Analysis for Electric, Diesel and Hydrogen Traction for Railways. Transportation Research Part D: Transport and Environment, 17(1), 28-34. doi: 10.1016/j.trd.2011.09.002

  • 14. Postgraduate courses: PhD/MPhil (various options) – see PG prospectus Railway Challenge (hydrogen-powered locomotive) • Participated in the inaugural Institution of Mechanical Engineers Railway Challenge in 2012 • Railway Challenge aims to encourage interest and participation in railway engineering • Developed, designed, and constructed the UK’s first hydrogen-powered locomotive ‘Hydrogen Pioneer’ • Traction system suitable for standard gauge vehicle • Proof-of-concept vehicle
  • 15. Prototype Locomotive: Conceptual Design • Peak traction load met by batteries, with hydrogen fuel cell rated for average demand of duty cycle • “Off-the-shelf” Proton Exchange Membrane fuel cell power-plant • Two options for hydrogen storage: 1) compressed gas or 2) metal hydride store • Pure regenerative service braking (i.e., braking energy captured and stored), with friction emergency brakes • Wireless remote control Coombe, D., Fisher, P., Hoffrichter, A., Kent, S., Reed, D., Rowshandel, H., et al.

  • 18. Drive-System Study • Compressed gas cylinder • Hydrogen mass flow meter • Instrumentation measures power consumption throughout electrical system • Demonstrated fuel cell efficiency around 40%+ • Overall efficiency only 15%: – lightly loaded – high proportion for auxiliaries – low motor efficiency Hoffrichter A, Fisher P, Tutcher J, Hillmansen S, Roberts C, Performance evaluation of the hydrogen-powered prototype locomotive ‘Hydrogen Pioneer’, Journal of Power Sources, Volume 250, Pages 120-127, DOI 10.1016/j.jpowsour.2013.10.134.
  • 19. Lessons from the Hydrogen Pioneer • Design & operation: – hydrogen system easy to design, install & operate – runs quietly & cleanly in contrast to competitors – third year using same hybrid drive – traction control required • Performance: – proof-of-concept established – it worked as intended – quick response and little difference between duty cycle & steady state – power plant matches manufacture claims – need to optimise for overall efficiency
  • 20. Feasibility Study of Stadler GTW • Modern regional train – Stadler GTW • Performance simulated for UK local regional line • Used diesel-electric baseline for journey time and range while retaining passenger space • Evaluated with: – hydrogen fuel cell – hydrogen hybrid (smaller fuel cell with batteries) • Both options viable with same journey time • Duty-cycle energy consumption: – hydrogen 34% less than diesel – hydrogen-hybrid 55% less • Well-to-wheel CO2 emissions: – hydrogen 55% less than diesel – hydrogen-hybrid 72% less Hoffrichter A (2013).
