Abstract

A recyclable fuel distribution system comprising a hierarchy of operatively linked (with fuel supply and reaction product collection elements) fluid fuel transport vehicles, fluid fuel storage tanks, fuel supply reservoirs (optional depending on specific use), and fluid fuel usage devices operatively linked to the storage tanks or supply reservoirs, as applicable. The fuel, during use, undergoes a reversible chemical reaction, whereby collected reaction product is reversible to the original fuel. At least one and preferably all of the vehicles, storage tanks and reservoirs contain a storage volume with separated chambers, adapted to inversely change relative to fuel being supplied and reaction product being collected and stored. As a result, a single volume during transport, storage, and use, provides the dual function of fuel supply and collection of reversible reaction product, with concomitant nearly halving of transport, storage and use volumes and costs. Electrical production with a zinc fuel which reversibly forms a zinc oxide reaction product is a particularly suitable fuel for the present system for use in large scale fuel cell applications. Applications range from large scale megawatt power levels for industrial levels to tens of kilowatts for homes and transportation systems down to several watts for portable electrical and electronic appliances and devices.
