Nottingham University

The University of Nottingham trialled their Energy Bag concept – a compressed air energy storage system – in EMEC’s wave test site in Scapa Flow.

They carried out the world’s first offshore installation of an Energy Bag at EMEC in the first few months of 2012.  The work, funded by E.ON, involved the installation and cycling of a 4m diameter open base Energy Bag, to prove the bag’s performance underwater and investigate any unforeseen problems with offshore installation.

Compressed air energy storage has the potential to economically deal with the intermittency inherent to most forms of renewable energy, and subsea storage in Energy Bags is a new technology which promises very low costs.
