An underwater battery has been developed in the Netherlands

The battery will store electricity generated by wind turbines.

Humanity has sufficient resources to obtain clean energy. Still, there is absolutely no control over the climate, which instantly rules out any possibility of long-term planning. So, wind turbines can be highly effective in the right weather conditions. However, they are useless during calm weather. This has led scientists to conclude that electricity should be stored.

The Dutch start-up Ocean Grazer recommends connecting wind turbines to battery storage located in the seabed. Then, following the engineer’s ideas, the surplus energy from wind turbines would drive a hydraulic pump that flows water into flexible inflatable tanks. Once the wind turbine stops producing enough energy, seawater squeezes the liquid out of the reservoirs, spinning the turbine that generates electricity.

The Ocean Battery system does have an efficiency of 70 to 80 percent, representing an extremely promising, environmentally friendly, and inexpensive project, given the 20-year life span of a single unit.
