University of New South Wales researchers have built a bicycle, called a Hy-Cycle, that can take riders up to 125 kilometres on a single $2 hydrogen canister refill.

Hydrogen for the Hy-Cycle is carried in a 2.5-kilogram canister that sits near the pedals. The canister feeds a fuel cell, which  continuously recharges a lithium-ion battery. The metal hybride inside the canister enables safe, user-friendly storage of the hydrogen.
