Energy storage technologies are complementary instead of competitive

Hybrid storage systems combine the strengths of both technologies flywheel-battery = power-intensive short-duration + energy-intensive

long-duration Additional benefits – e.g. extend batteries lifetime

Increases value proposition Short & medium discharge applications

(few secs to 1 day storage)
