An Italian manufacturer of fuel cells, Electro Power Systems, is wooing would-be customers in the telecommunications industry with what it says are the first fuel-cell systems that don't require an external fuel supply.
Its systems bundle together fuel cells and an electrolyzer to generate their own fuel, hydrogen. The company's most-recent innovation is hooking the system to wind turbines and solar panels to harness their energy to make the hydrogen.
Developing an all-in-one system that uses energy from renewables to produce and store hydrogen "is the holy grail for a lot of (fuel cell) companies," says Kerry Ann Adamson, a director at Boulder, Colo.-based Pike Research.
