At 1:20, the video states that electricity can't be stored directly, but isn't that how capacitors work?

Description: Although we’ve found ways to generate electricity from renewables, storing energy for future use isn’t so easy. Why is this, and what strategies are engineers using to solve the storage problem?

It is actually stored in an electrostatic field. See this wikipedia article for more information: https://en.wikipedia.org/wiki/Capacitor#Energy_storage

can't we use reservoirs that would pump up then drain down for kinetic energy?

what about alternating the different types of renewable energy through the course of the day? Solar during day time, Tidal during night time, etc. Since it kind of is a renewable resource, why store it when you can have more limitlessly? Small gadgets can use batteries which can be recharged with renewable energy, and how about cracking down on the use of fossil fuels only for emergency or special situations?

How do you store electricity as potential energy? Wouldn't it just dissipate?

  The system basically makes use of gravity to store energy. When available, excess power on the grid is used to pump water from the lower reservoir to the higher one, there by storing energy as potential energy. When needed, the water from the higher reservoir is made to turn the turbine blades to generate electricity.
