Water can be stored easily as a liquid in tanks or sponges, as a solid (ice) wherever it can be piled or as a hydrate - with the water molecules bonded to other non-water molecules. Hydrates are usually powders. Water may also be absorbed into the interstices of porous materials or in tanks as a gas - although it would have to be at fairly low pressure to remain a gas.

Water can be stored in containers such as barrels, tanks or cisterns. It can also be stored in natural reservoirs such as lakes, ponds or rivers. Underground aquifers can also store water.
Energy can be stored in the form of potential energy by lifting an object against gravity or compressing a spring. It can also be stored in the form of chemical energy in batteries or fuel.
A book placed on a shelf, a coiled spring, and water stored in a dam all have potential energy.
Electricity can be stored in batteries, which convert chemical energy into electrical energy. It can also be stored in capacitors, which store electrical energy in an electric field.
The heat is stored in water vapour is latent heat.Latent heat describes energy that is not stored as the internal energy (i.e. temperature) of an object but in its phase state.For example, in the atmosphere heat that is transported by an air parcel that contains more water vapor than its surroundings. Because energy is needed to turn water into water vapor, water vapor is a way for a body to store energy (along with potential energy, kinetic energy, and sensible heat). If the water vapor is returned to a liquid or solid phase (by condensation or sublimation), the stored energy is released as sensible heat.
No, water running from a tap is kinetic energy because it is in motion. Potential energy is the stored energy that an object has due to its position or state, such as water stored behind a dam.
