High-power supercapacitors – already found within terrestrial electric cars, trains, lifts and cranes – are on their way to space.

PARIS (ESA PR) — An ESA-led project with Airbus Defence and Space developed and tested a supercapacitor design able to provide brief bursts of very high power levels to space missions as required. Potential uses might include operation of high-power satellite radar systems, to stabilise overall onboard power during solar eclipses or other such events or launcher thrust vectoring.
