Dutch patent for underwater energy storage

What is underwater compressed energy storage?

Underwater compressed energy storage is similar to CAES, with the major difference being that the air is compressed in a container located underwater. Several approaches to UWCAES are under development including the utilization of distensible air container also referred to as an Energy Bag , .

Can a buoyancy based energy storage be used in deep sea floors?

An international research team has developed a novel concept of gravitational energy storage based on buoyancy, that can be used in locations with deep sea floors and applied to both the storage of offshore wind power and compressed hydrogen.

What is offshore energy storage?

ORES (Ocean Renewable Energy Storage) is another approach to offshore energy storage which utilizes large concrete spherical structures mounted to waterbed , . Water is pumped from these large containers during charge phase and is allowed to reenter the container through a turbine on discharge phase.

Is underwater gravity energy storage a viable solution for weekly energy storage?

Underwater gravity energy storage has been proposed as an ideal solution for weekly energy storage, by an international group of scientists.

Can pumped-hydro storage be used to store green hydrogen?

The novel technology is considered an alternative to pumped-hydro storage for coasts and islands without mountains that are located close to deep waters, and may also be interesting for PV if used to store green hydrogen. The proposed storage solution can be implemented at a minimum depth of 300 meters. Image: PublicDomainPictures/Pixabay

Can BBES be implemented offshore without divers?

BBES can be implemented offshore from water surface without divers lowering implementation costs. Conclusions have not been drawn as to the achievable round-trip efficiency of BBES as this is subject for further research utilizing a more elaborate experimental apparatus.
