Definition of Off-Highway and Heavy Duty Sector

2

  • Working Machines; pieces of ‘plant’
  • Mobile, but often ‘site’ based
  • Includes heavy goods transport

Construction Agriculture Heavy Goods Transport Heavy Industrial

Characteristics of this Sector

3

  • High Energy Use (e.g. 40T excavator 2MW hrs per 24hrs)
  • Continuous Operation
  • Undeveloped Locations (e.g. infrastructure ground works)
  • Variable duty cycle
  • Long life expected (20,000+ hours)
  • Economics based on well defined ‘cost of ownership’

– Including resale value

T echnologies – Prime movers

  • Combustion Engines (HC, H2, NH3, etc.)
  • Electric (Motors, Controls)
  • Fuel Cells (H2, CH4, etc.)
  • Others e.g. Liquid Air Engines

All these have routes to Zero AQ emission & low/zero CO2

Summary

Heavy Duty and Off Highway Machines have different requirements from LD automotive:

  • High energy usage
  • continuous operation
  • varied duty cycles
  • site based operation
  • remote locations – no infrastructure
  • cost of ownership driven

Powertrain solutions are required that address these requirements

  • Fuel availability and ‘fill’ time
  • Efficiency
  • Sustainability
  • Cost of ownership

Conclusions

To successfully move along the path to a zero emissions, low CO2 future, we need to:

  • Legislate for Outcomes, not technologies. Outcomes need to be holistic
  • Apply appropriate technology solutions to achieve the outcomes
  • Ensure the right choice of Technology Solution is made based on

application & usage pattern
