Balancing Supply and Demand - Ocean Grazer
On a windy day sea wind farms produced
more energy than can be used. On a calm day the demand is greater than the
supply. There is a need to somehow store the excess energy when it is produced
and store it so that it can be used on days when the demand is greater than the
supply. There are many projects working on this and ocean grazer is feasible
one. The Ocean Battery is a scalable, modular solution for utility
scale energy storage that is produced by renewable sources such as wind
turbines and floating solar farms at sea. Ocean Battery is a pumped hydro
system in a box that provides eco-friendly utility scale energy storage up to
GWh scale. The mechanism is based on hydro dam technology, that has proven
itself for over a century as highly reliable and efficient.
To store energy, the system pumps water
from the rigid reservoirs into the flexible bladders on the seabed. Now the
energy is stored as potential energy in the form of water under high pressure.
When there is demand for power, water flows back from the flexible bladders to
the low pressure rigid reservoirs. Driving multiple hydro turbines to generate
electricity.
