The Credo E-Bone concept bus is the brainchild of designer Peter Simon, who wants to make public transportation greener. The E-Bone is a zero-emission bus that generates power from a system of hydrogen fuel cells and lithium batteries. Powered by four in-wheel electric motors, the bus carries its power sources on its roof.

The shell of the bus has been made from lightweight composite plastic with a bone-like structure. The lightweight construction makes the concept energy-efficient, which betters its performance.
