A recent study shows that pure electric vehicles perform better than hydrogen fuel cell vehicles in terms of emission reductions. The study was published in the journal Energy, and it is said that in addition to providing a more environmentally friendly means of transportation, hydrogen fuel cell vehicles do not provide users with more energy advantages.
Markus Felgenhauer, a Ph.D. candidate from the Technical University of Munich in Germany and the first author of the study, said the study investigated the energy use of communities using large-scale electric vehicles.
Felgenhauer pointed out: "By research, we found that pure electric vehicles are a more economical option for CO2 reduction because they are cheaper and have higher energy efficiency." Electric vehicles are currently divided into two types, one It is a pure electric vehicle with a rechargeable battery, and the other is a hydrogen fuel cell vehicle that converts hydrogen into a clean electric energy source. Pure electric vehicles and hydrogen fuel cell vehicles have zero CO2 emissions during operation. However, in order to charge large-scale or supplement hydrogen fuel for both models, it is often necessary to build a costly infrastructure.
At present, policy makers also want to find out which models of pure electric vehicles and hydrogen fuel cell vehicles can achieve the best emission reduction effect at the lowest cost. Sally Benson, a professor at Stanford University in the United States, said: "For deep decarbonization of the global energy system, to achieve the best results at the lowest cost, similar research will become very important." In this study, researchers on pure electric vehicles and hydrogen The cost of fuel cell vehicles will be lower in the future.
Felgenhauer said that in terms of total cost, pure electric vehicles perform better than hydrogen fuel cell vehicles in terms of emission reductions. In order to gain an advantage in the competition, the cost of hydrogen fuel cell vehicles is usually lower than that of pure electric vehicles, but in the long run, hydrogen fuel cell vehicles will cost far more than pure electric vehicles.
