Few hydrogen fueling stations exist, and it will cost billions to build an infrastructure that will make FCVs practical.

Critics say that hydrogen is difficult to store and that producing the hydrogen makes FCVs less efficient than other types of alternative vehicles, such as electric or natural-gas-powered cars.

Even though FCVs may represent the future of the industry, they are still not practical for most applications. However, the hybrid technology and biodiesel powered cars are already practical and many of the mainstream international rental car companies are already offering these alternative fueled vehicles. For example, Hertz will rent a Toyota Prius or comparable model as well as a bio fueled Volkswagen Jetta at many locations (Hertz, N.d.).

Lotus Rental Car should meet its customers' demands for clean...

The two most practical technologies that could be added now without many challenges would be the hybrid technology and biodiesel power engines. Although FCVs are developing quickly, there are currently many limitations to the use on a daily basis for most users. Therefore, it is recommended that Lotus Rental Car begin its alternative fuel expansion through these practical first steps.
