Energy resource system

An energy resource system 1 includes an energy resource management server 2, a first remote energy resource 3, such as a mobile communication device, and a second remote energy resource 4, such as another mobile telecommunication device. The server further comprises means for receiving energy availability and energy request messages including geographic location indicators from the remote energy resources. The server further determines counterparties in an energy resource transfer based on received energy availability messages, and received energy request messages, and transmits, to one or both of the counterparties, location information of the other counterparty to facilitate the exchange of energy. Counterparties may be determined on energy resource type, energy resource level, energy availability quantum, required energy transfer quantum, transfer time, energy availability time window, and geographical proximity. Remote energy resources include portable fuel cell power sources having associated fuel reservoirs and batteries.
