Abstract: Diesel, liquefied natural gas (LNG), pure electric and hydrogen-powered garbage transfer trucks were chosen as the research objects. The applicability of different trucks from different dimensions, such as vehicle endurance, total cost of ownership, carbon emission and long-term competitiveness were comprehensively studied. The results showed that pure electric transfer truck had a critical working distance of 23.7 km within 8 hours operation period, due to the short battery range and long charging time. Considering the total cost of ownership and future trend of carbon price increase, hydrogen-powered and pure electric transfer trucks would achieve competitive parity with LNG transfer trucks by 2030 and 2050 under short-distance (≤23.7 km) scenario. Under long-distance (>23.7 km) scenario, the competitive parity of hydrogen-powered transfer trucks would be 2035, but pure electric transfer trucks didn’t have competitive advantage for a long time. At present, the clean alternative of garbage transfer truck should prefer a “gas-primary, electric and hydrogen secondary” approach. And differentiated comprehensive energy supply facilities should be built based on scenario.
