OCEAN BATTERY
Utility scale
offshore energy storage
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.
Discover the unique advantages of the Ocean Battery
Offshore Storage
Ocean battery provides utility scale energy storage at the source, it can be deployed in existing and new offshore wind farms. In this way we can reduce local peak loads in the network and optimally match supply and demand.
Reliable & Affordable
By applying proven hydro dam technology, we can guarantee a long lifetime of decades and a high round-trip efficiency up to 80%. This makes our technology reliable and affordable.
Eco Friendly
Our technology is sustainable and eco-friendly, the Ocean Battery does not require rare earth materials and uses clean water as the energy carrier. The structure is designed to enhance marine life.
Energy when we need it and where we need it
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.
