Hamilton Sundstrand has selected Distributed Energy Systems to develop and supply electrolysis cell stacks that produce breathable oxygen within nuclear submarines. As a first step in this relationship, the parties have entered into a contract for cooperative development of a cell stack suitable for the next-generation U.S. and British Navy submarines. The contract, which extends through the fall of 2008, involves development work valued in excess of $1 million.

The cell stacks will enable the water electrolysis-based oxygen generation systems to split water into its hydrogen and oxygen elements. Once these new cell stacks are successfully developed, Hamilton Sundstrand anticipates Distributed Energy Systems will supply production versions to Hamilton Sundstrand for use in new nuclear submarine programs for which Hamilton Sundstrand oxygen generating systems may be selected.

Hamilton Sundstrand Space, Land & Sea, a business unit of Hamilton Sundstrand, designs and manufactures oxygen-generating systems, atmosphere monitoring instruments, and propulsion systems for the U.S. Navy and international navies.

Distributed Energy Systems develops electrolysis systems for the on-site production of hydrogen in commercial, industrial and research applications. Capabilities include high and low pressure oxygen and hydrogen, with the elements produced by the cell stacks usable either in a process, in the gaseous form, or as a source of energy.
