Boeing has delivered its reversible solid oxide fuel cell, for generating clean electricity, to the U.S. Navy for testing.

The fuel cell system is designed to generate, compress and store hydrogen from renewable sources such as wind and solar to produce zero-emissions electricity. Boeing's delivery to the Navy follows 16 months of development.

The technology is capable of both producing and storing energy. The first unit was commissioned on the Southern California power grid prior to its installation on the Navy's 'microgrid' for further testing.

"This fuel cell solution is an exciting new technology providing our customers with a flexible, affordable and environmentally progressive option for energy storage and power generation," Boeing Advanced Technology Programs director Lance Towers said.

Boeing officials say they were able to develop the fuel cell using their experience with the energy systems used for their unmanned undersea vehicles.

The fuel cell was developed for both military and civilian use. The Navy's testing will determine its ability to meet military and commercial needs.
