T-1B1b-TE-7 - Improved heavy truck engine technology

Background

IPCC WG3 definition: .

Improved vehicle and engine technology can reduce emissions from fossil-fueled trucks. This shift can help reduce emissions in the short term, until zero-emission technologies reach their full potential.

Transition Element

• Type of shift: Utilisation Shift
• Activity: TBD
• Operation: TBD
• ATOC: TBD

Activities

Improves:

• T-1B1b-A-2 - Diesel HGV
• T-1B1b-A-3 - Pure electric HGV
• T-1B1b-A-5 - Hydrogen HGV
• T-1B1b-A-4 - Shift to gas heavy trucks
• T-1B1b-A-1 - Petrol HGV

Parameters

Parameter	Unit	Description
energy_intensity_freight_heavy_trucks_diesel	kwh_tonne_km	Average energy intensity heavy trucks (diesel)
heavy_truck_efficiency_improvement_factor	percent	Engine efficiency improvement factor for HGVs
