Open Water Power has developed a novel aluminum-water platform technology for undersea power generation. Invented and patented by our founders at MIT, the electrochemical system provides safe, scalable & non-toxic energy storage with extremely high energy density, resulting in a 10x improvement in the endurance of Unmanned Underwater Vehicles (UUVs) and sensors.

Our Technology

Open Water’s technology harnesses the significant electrochemical energy inherent in aluminum metal. While a variety of mechanical and materials-based hurdles have traditionally made this energy difficult to access, our proprietary and patent-pending technology, developed at MIT, overcomes these issues to deliver a power system with 10x the energy density of the best lithium-ion systems.
In addition to improved energy density, our aluminum fuel cell technology is inherently safer and more stable than many other battery and fuel cell chemistries, as shown in the figure below. Prior to activation, our systems are chemically inert, with no risk of explosion and a virtually unlimited shelf life. Once our systems are activated with water, their safety profile is similar to that of household alkaline batteries.



Use Cases

From both an operational cost and a strategic point of view, current UUV use is limited by the need for manned surface and submarine support vessels for deployment, operation & retrieval.  A significant increase in the range of UUVs would allow many operations to be conducted by UUVs launched directly from shore, without the need for a support vessel and its crew.  Two examples–one from the oil & natural gas industry and one from the arena of national defense–are depicted below that illustrate how significant of an impact Open Water’s technology could have on such operations.

Oil & Gas Operations in the Gulf of Mexico:

Current vs. potential out-and-back ranges for a standard 21″ UUV in the Gulf of Mexico. Current UUV range (red circles) is insufficient to reach the vast majority of pipeline assets and lease blocks. The same standard UUVs powered by Open Water’s technology would offer complete coverage (gray area) of the Gulf’s resources, enabling fully autonomous ocean floor surveying, pipeline inspection and well monitoring for virtually all assets in the field, requiring little more than shore launch & recovery at, for example, Galveston, TX and New Orleans, LA.

US Naval Operations in the North-West Pacific:

Current vs. potential one-way range for standard 21″ UUVs launched from active US Navy bases in the north-west Pacific. Current UUVs have limited strategic value due to their short range (red circles). The same standard 21″ UUV equipped with Open Water’s technology would be capable of delivering sensors and other payloads to nearly any coastal or offshore location in that theater (gray area) without the need for manned vessels.
