Table 1 Key assumptions for heavy-duty truck activity and energy projections.
From: Near and long-term perspectives on strategies to decarbonize China’s heavy-duty trucks through 2050
2015–2050 assumptions | Sources | |
|---|---|---|
Vehicle average lifetime | 10 years | |
Annual average vehicle kilometers travelled | Intra-city: 50,000 km/vehicle/year | |
Inter-city: 100,000 km/vehicle/year | ||
Inter- and intra-city travel shares | Intra-city: 10% | Based on HDT driving cycle standard48 |
Inter-city: 90% | ||
Total stock | 2015: 5.3 million | Calculated by bottom-up stock turnover model |
2050: 10.5 million | ||
Fuel shares | 2015: 97.6% diesel, 2.4% liquefied natural gas | Weighted-average shares of all heavy-duty truck types from Ref.7 |
Projected fuel shares vary by scenario (see below) | ||
Final energy intensity | 2015 diesel trucks: 38.3 L/100 km (13.8 MJ/km) | Weighted-average fuel consumption of all heavy-duty truck types as reported in Ref.7 |
2015 LNG trucks: 81.3 L/100 km (18.3 MJ/km) | ||
Projected intensities vary by scenario as discussed below |
