Biological Technologies Office -- BioLogical Undersea Energy (BLUE)

Funding Agency:
Defense Advanced Research Projects Agency

The BioLogical Undersea Energy
(BLUE) program seeks to develop power supplies that capture and convert microscopic
forms of marine biomass (e.g., dissolved organic matter, phytoplankton, zooplankton) or
other substances (e.g., microplastics) into electrical power. These power supplies are
intended for onboard use by ocean-deployed sensor systems presently powered by
batteries. They are to self-refuel on marine biomass, operate fully submerged, and deliver
battery-level power without being serviced far longer than is possible by comparably
sized battery packs. BLUE power supplies will enable high capability and long endurance
ocean-deployed sensor systems.
