초록

In order to achieve carbon neutrality in road transport, the transition demand to zero-emission vehicles is significant, as it accounts for about 97% of greenhouse gas emissions in domestic transportation. In particular, heavy-duty trucks contribute significantly to greenhouse gas emissions, because of their higher annual mileage and usage of diesel engine. However, freight trucks are operated for the purpose of profit. Therefore, it is crucial to conduct research on the economic feasibility of heavy-duty trucks transitioning from internal combustion engines. This study analayzed total cost of ownership for zero-emission trucks, projecting total cost of ownership parity with internal combustion engine trucks by 2040. In addition, the greenhouse gas reduction effect, which is the ultimate goal of conversion to zero-emission trucks, was compared through well-to-wheel analysis. The result shows that fuel prices are pivotal in reaching total cost of ownership parity for zero-emission trucks. For the successful conversion of heavy-duty trucks to zero-emission, it is imperative to form competitive fuel prices with internal combustion engine vehicles. Policy implementations that facilitate the complementary distribution of hydrogen fuel cell trucks and battery electric trucks should also be a prerequisite. Furthermore, the decarbonization of fuel production concurrently with the transition to zero-emission vehicles is essential since the greenhouse gas reduction effect of zero-emission trucks varies depending on the increase of renewable energy generation and the development of clean hydrogen production technology.
