What is deep sea pumped hydro storage?

Deep sea pumped hydro storage is a novel approach towards the realization of an offshore pumped hydro energy storage system (PHES), which uses the pressure in deep water to store energy in hollow concrete spheres. The spheres are installed at the bottom of the sea in water depths of 600 m to 800 m.

What is a conventional approach to energy storage?

The conventional approach to energy storage is through pumped hydroelectric plants, Fig. 1. These use the energy produced by a power plant to pump water into a water reservoir at a high elevation during off-peak periods. Water is then flushed through a conventional hydroelectric turbine into a lower-altitude basin during high demand times.

How does a water storage system work?

The inflowing water drives a turbine and a generator that feeds electricity into the grid. This represents the discharging phase of the storage system. Recharging is achieved by pumping the water out of the sphere against the surrounding water pressure using energy from the grid.

How is energy stored in a water tank?

Energy is stored by using a turbine that empties the pipes and works against the external pressure (100 bar in this case). Pipes must be connected to each other and the water spill is achieved by a suitable collection cavity positioned below the pipes stack in order to facilitate their emptying.

Which equation can be used to evaluate stored energy?

The equation that can be used to evaluate the stored energy is the following: (1) E s t o r e d = V · ρ · g. h where V is the volume of the tank, ρ is water density, g = 9.81 m/s 2 gravity acceleration, h depth. As an example, we assume that V = 40 × 60 × 10 m 3, h=1000 m and ρ=1035 kg/m 3.
