How is hydroelectric energy stored and how is it released?

Answer 1

There are schemes where water is pumped up into a reservoir with pumps that can be reversed and become generators when peak power is required. There is one at Dinorwic inWales UK. Ofcourse any hydro scheme can include storage, the water stored in the reservoir is potential energy to be released when required.

Answer 2

As the name suggests.Hydro electricity is generated from moving water(river/waterfall).moving water posses high kinetic energy. this energy of water is used to rotate the turbine.the turbines work very similar to a dynamo. They convert rotatory energy to electrical energy and hence electrical power is obtained.

Answer 3

Hydroelectric energy is not stored. By definition, "hydroelectric" means that power is already generated, leaving only batteries, flywheels, or superconductors as energy storage devices...

Basically hydroelectric energy is just electricity that was generated using hydro power. You can store electricity by the means described above, but most likely hydroelectric energy is used as it is produced and not stored.
you could store hydroelectricity (the electricity produced by hydro power) the same way you would store any other electricity. Most likely, you would store it in a battery (after converting it from AC to DC).

Answer 4

Water is stored behind hydro-electric dams. Then when power is needed, water is released through the dam to produce power through electricity turbines.

When electricity is not in demand, water can be pumped back behind the dam so it is available for later use.

Answer 5

well, barrages are built in river estuaries that have large tidal ranges such as the River Severn in the UK.

i hope this helps, becasue i have to do this for a project and i never ever cheat but i wished someone wouldve helped me with this question but obvi i had to figure it out on myslef soo yeah have fun with tidal waves you loser?
