Navy tests first ‘reversible’ clean energy fuel cell storage system

Boeing has announced that, after 16 months of development, it has delivered a "reversible" fuel cell for the U.S. Navy that stores energy from renewable sources and generates zero-emissions electricity.

The Solid Oxide Fuel Cell (SOFC) system, which can generate 50 kilowatts (KW) of power, is the largest of its kind and can use electricity from wind or solar power to generate hydrogen gas, which it then compresses and stores.
