FastCAP has identified a variety of applications where the proposed technology will have a significant impact in energy storage weight/volume reduction, complexity reduction and life extension. They include: Energy Storage for deep space exploration missions with extreme wide temperature requirements (i.e. Titan Missions, Comet-Asteroids Missions, Mars Missions, Lunar Quest Missions), Electric Propulsion Systems; GPS/Guidance; Deep Space Transponders and Radars; Satellites; Cube-Sats; Payload Operations; Exploration Vehicles (landers, rovers); Pyro Initiators for the stage separation of the rockets; Flight Termination Systems (FTS); Emergency Detection Systems (EDS); Peak Power harvesters from power sources such as PVs. In addition, there are specific applications suggested by FastCAP's aerospace industry partners for the proposed technology: Power optimization for Launch Vehicle (LV) applications for pyro initiators; Hydraulics power augmentation for the Next Generation Launch System (NGLS) program; Power optimization for Integrated Vehicle Fluids (IVF) system for the Common Upper Stage program; Power optimization for Lite and Heavy Electric Propulsion Upper Stages utilizing Hall Effect Thrusters to enable heavy USG spacecraft to GSO and NASA Interplanetary Missions. A new generation of low temperature ultracaps would enable a variety of developments and advances in the realm of renewable energy production. For example, ultracaps are widely regarded as an ideal component to be used to feather the blades of large-scale wind turbines in high wind conditions, but currently available ultracaps are not able to perform effectively in high altitude and other extreme cold locations (Arctic, Antarctic). Similarly, an ultracap capable of extreme low temperature performance could enable significant performance improvements in other exploratory and energy production technologies, including cold water tidal and wave energy production operations, and deep sea drilling operations. Outside of renewable and traditional energy exploration and production, an ultra-low temperature ultracap would be useful in a variety of mission critical defense and civilian avionics applications, where current energy storage devices require thermal management to function properly.
