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.
Producing renewable energy is crucial for a climate neutral economy. This energy transition requires a significant change in the energy system. More and more solar and wind turbine parks are being realized onshore and offshore to contribute to a sustainable society.
The planned global production of offshore wind, for the year 2050, exceeds 1150 gigawatts. Soon, weather conditions will dictate the timing of renewable energy production, causing large fluctuations.
To grow to a system where renewable energy is the norm, the biggest hurdle must be solved: energy storage. At Ocean Grazer, we tap into this huge potential of renewable energy by introducing the Ocean Battery. We are ready to meet future utility scale energy storage needs.
Ocean Power converts wave energy into electricity, using innovative floater blankets that are adaptable to each incoming wave that maximizes the power output.
Ocean Grazer is a Dutch start-up and a spinoff from the University of Groningen. Since 2014, the Ocean Battery has been in development at the University of Groningen. Over 100 students graduated so far have worked on relevant topics: developing predictive models, building experimental prototypes and more.
Since 2018 Ocean Grazer is turning knowledge and intellectual property into commercial products. The start-up located in Groningen, the Netherlands, is led by Frits Bliek (CEO) and Max Duursma (COO): two professionals with over 20 years of experience in the maritime and energy sector, and Marijn van Rooij (CTO), who has spent 5 years to research regarding the Ocean Battery concept. Currently, Ocean Grazer is focusing on bringing the innovative Ocean Battery to the market

The Ocean Grazer is a conceptual energy collection platform, projected to house several renewable energy generation modules, including wave energy, solar energy and wind energy. The development of the Ocean Grazer platform has been carried out by the University of Groningen in the Netherlands,[1] since 2014, and now by a spin-out company Ocean Grazer BV.[2]
The concept of the platform is currently on its version 3.0[3] centering on the modular design as opposed to the massiveness of the platform, as in the previous concepts. The majority of the harvested energy for all concepts is to be delivered by a wave energy converter that uses the motion of ocean surface waves to generate electrical energy.[4]
The company has also developed the Ocean Battery, which is a modular subsea pumped-storage hydroelectricity system.[2] Unveiled in 2021, the technology can be deployed around offshore wind farms or floating solar, to store excess power generated.[5]
As useful as renewable energy sources are, they need to be backed up by storage systems that hold energy for times when the Sun isn''t shining or the wind isn''t blowing. 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. It is made up of three components that together function on a principle similar to that of a hydro dam.
Buried in the seabed is a concrete reservoir that holds up to 20 million liters (5.3 million gal) of fresh water, stored at low pressure. A system of pumps and turbines connects this reservoir to a flexible bladder on the seafloor. Excess electricity from the renewable sources can be used to pump water from the reservoir into the bladder. When the energy is needed, the bladder releases and, driven by the pressure of the seawater above it, squeezes its water back down to the reservoir, spinning turbines on the way to generate electricity that''s fed out into the grid.
The Ocean Grazer team says that the system has an efficiency of between 70 and 80 percent, and should be able to run an unlimited number of cycles over an operation lifetime of more than 20 years. It''s also fairly scalable – each concrete reservoir has a capacity of 10 MWh, so adding more of these can increase the overall capacity. Extra units of the pump and turbine machinery can also be added to boost the power output, if more energy is needed quickly.
The Ocean Battery concept is intriguing, but it''s far from the only ocean battery design in the works. Subhydro outlined a similar idea to pump seawater out of tanks placed at the bottom of the sea, then when electricity is needed the water is let it back in, spinning turbines as it fills the tank. MIT also described a similar concept using hollow concrete spheres. Another recent design worked off buoyancy, using electricity to drag and hold balloon-like containers underwater, then releasing them to generate electricity.
