Competitive Analysis of Suitability for Garbage Transfer Trucks with Different Energy Types Under Carbon Emission Reduction Constraints:A Case Study of Shenzhen City
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.
