After extensive research, I believe hydrogen would be the best alternative oil for the future of GM vehicles. Unlike the carbon dioxide byproduct in traditional gas combustion engines, hydrogen burns up to 90% efficiency; furthermore, once consumed the byproduct is water. However, there are many challenges into making hydrogen energy a reality. First, hydrogen fuel cells are currently is too heavy. According to consumer research, vehicles need to obtain enough hydrogen for 300 to 400 mile capacity. This requires the hydrogen to be compressed, and the tank must be able to withstand the weight of the compression. Safety is one of the most important attributes in the commercialization of GM vehicles; however, adding extra weight to the tank to support enough hydrogen could result in safety concerns. Second, hydrogen fuel cells cost more to manufacture than current combustion engines. The material costs would need to come down for mass consumer purchasing to take place. The cars should be less expensive as a

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
