Ocean energy storage

What is Ocean battery?

Ocean Battery is a new design for an energy storage system that functions a bit like a hydroelectric dam at the bottom of the sea. Developed by Dutch startup Ocean Grazer, the Ocean Battery is designed to be installed on the seafloor near offshore renewable energy generators, like wind turbines, floating solar farms, tidal and wave energy systems.

How can the offshore environment be used for energy storage?

The offshore environment can be used for unobtrusive, safe, and economical utility-scale energy storage by taking advantage of the hydrostatic pressure at ocean depths to store energy by pumping water out of concrete spheres and later allowing it to flow back in through a turbine to generate electricity.

Are ocean energy sources sustainable?

This is believed to be a crucial finding. Many countries around the globe aim to utilise ocean energy sources to supply their increasing energy demand in a sustainable manner.

Why do we need Ocean Energy Engineering?

Therefore, the research and development in ocean energy engineering should be fostered by governments and private sector around the globe so that we can use these reliable and clean renewable energy sources for supplying our increasing global electricity demand.

Can ocean energy technologies supply global electricity demand?

Finally, according to the IEA Ocean Energy Systems Technology Collaboration Programme (OES TCP) if worldwide deployment could be achieved different ocean energy technologies could supply current global electricity demand of close to 20,000 TWh (valid for the year when that study was conducted) (IEA, 2017b).

What is ocean wave energy?

3.1. Fundamentals of wave energy Ocean wave energy is one of the most abundant clean, frequent, renewable, periodic and predicted energy sources around the globe, which has the potential to compete with the current use of fossil fuels (Alamian et al., 2017, Mustapa et al., 2017).
