Why?
• Reduction of harmful emissions
• Breathable harmful to health
• Atmospheric pollutants
• Reduction of Greenhouse gases CO2
• Carbon footprint
• Responsible for Climate Change
• Fuel savings and cost reductions
Reduction of “Carbon Footprint”
• Carbon Dioxide CO2
• Considered a main “Greenhouse Gas”
• What can be done?
• Reduce the amount of fuel burnt
• Change the type of fuel burnt
Carbon Reduction
• Turning point for vehicle drive
technologies
• No single answer to carbon reduction
issues
• Diesel electric hybrid is only one
possibility
• Choice of technology may be locally
driven
• Source of fuel
• Route mileage
• Terrain
• Needs to have retrofitable option to
be future proof
What we will offer…
• Optare will offer the operator a
choice to match these local needs
• Choice of fuel
• Choice of technology
• Future proof engineering allows for
improvement and ongoing change
• Retrofitable solutions, we need to
address the whole vehicle parc
Enhanced Diesel
Driver’s Binnacle
All operations which directly affect safety, fuel
economy and improved efficiency are monitored and
fed back to the driver interface.

Alternative Fuels
Methane
• Least environmental impact of all fossil fuels 26% less carbon than
diesel
• Can be derived from landfill waste gas or anaerobic digestion
• Use in a gas engine (Spark ignition)
• Actual engine performance 25% worse! So no net carbon benefit
• So what do we do?
Dual Fuel Gas-Diesel
• Engine efficiency same as diesel
• Fuel consumption as diesel
• CNG Compressed Natural Gas
• Roof mounted tanks
• Can be provided from LCNG plant
• To 80% substitution
• 20% reduction in CO2 on natural gas
• 50% reduction using BioMethane
• Retains existing diesel engine
• Can be retrofitted
Dual Fuel System
Solo Dual Fuel
BioMethane Dual Fuel Summary

Hybrid Drives
Hybrid drives
• Reduces the amount of fuel burnt
• Utilises energy wasted in braking
• Stores the energy
• Reuses the energy to propel the vehicle
• Operate the engine at its optimum condition
• Savings of 20% to 30% in fuel and hence CO2
• Diesel Electric can be expensive!
