Environmental Legislation
Euro 6 Requirement
Edinburgh and East Lothian AQMA’s
Local Authority and National Environmental StrategiesCustomer Expectations
Human Health
Influencing Factors
Environmental Legislation• 42% Carbon Reduction by 2020• 80% Carbon Reduction by 2050• Almost complete decarbonisation of road transport
by 2050
Local Authority and National Environmental Strategies
• Low Emission Strategy for Scotland• Sustainable Energy Action PlanCustomer Expectations• Lower Carbon Footprint• Comfortable, Reliable Journeys• Minimal Noise and Odours
Influencing Factors
Human Health• Impact to heart and lungs
Edinburgh and East Lothian AQMA’s• Central, West and East air quality standards areas
SCRT®
2004 Euro III B7RLE
SCRT®
• 70% reduction in NOx• 90% reduction in PM
• 99% reduction in other pollutants
‘Get there Greener’
SCRT® System
• Filter converts soot to ash and holds it inside the tank until it needs changed
• SCR catalyst reaction absorbs NOx
• Outlet is H2O
• CRT injects Adblue
Hybrid Journey
• Diesel-Electric hybrids• Operate on AQMAs• Regenerative braking• Stop-Start technology
Cleaner and Greener Technology
Series Hybrid Parallel Hybrid
ADL Enviro 400H
• Route 10
• 15 vehicles at Euro 5 EEV
• 2 AQMAs
• 10 x vehicles at Euro 5 EEV• 40 x vehicles at Euro 6• Four routes fully converted
Volvo 7900H
• Three AQMAs
• Savings in fuel of up to 39%• Up to 39% reductions in CO2• Reductions in NOx and PM
Emission Savings
Lothian Buses and Lothian Country Buses Euro 3 and above
City Mobility
The Next Step toward Zero Emissions
City Mobility
How does it work? - The Vehicle
The new concept is based on the chassis and body work of the existing Volvo 7900H with the addition of:
• Charging rails
• Bigger batteries for more electrical storage
• Enhanced driveline
• The ability to move at normal road speeds with zero
emissions
The Vehicles - Additional Components
Maintenance Charging Port
Charging Rails
Charge Switching Unit
Energy Storage System
Enhanced Driveline
Cabin Assembly Mast Inverted Pantograph
Charging Infrastructure
Telematics and Geofencing
• Telematics gives a full run down of real time or historic vehicle
performance statistics
• Gives information on speed, braking, driver performance, economy
performance
• Geofencing allows the zoning of pure Electric Motor operation
• Reports location based data
Energy, Emissions and Pollutant Reductions • Significant fuel savings• 40% of typical route mileage in electric mode• Silent Operation - Lower Noise Pollution
Emission Savings
Extended Zero Emissions running at normal speeds• Estimated 11 km in Electric Mode• No emissions when travelling through AQMAs
Other Cities Hamburg - Operational Demonstration
Other Cities Stockholm - Operational Demonstration
What does the future hold?
• Exhaust-free operation
• Silent
• Enables indoor bus stops
