Compressed hydrogen has a higher energy density than electricity, can be generated from a wide range of raw materials, and is easy to store, making it a promising future energy source. That's why Toyota envisages a sustainable society in which hydrogen energy is in widespread use―a society embodied by this concept vehicle.

Clean generation of hydrogen from a wide range of primary energy sources will make local, self-sufficient power generation a global reality, and fuel cell vehicles will take on a new role as power sources within their communities. Toyota's aim is to add an all-new sense of purpose to the automobile by turning fuel cell vehicles from eco-cars into energy-cars.
