Coastal Erosion Eliminator is an early stage spin-out from 4NRg. It holds a patent for a unique device that combines both a near shore wave and tidal energy generator, with a method for protecting exposed coasts from erosion. This creates a method of defending valuable shoreline (The Foresight Future Flooding Report estimated the value of assets at risk from flooding at around £200bn) which can fund itself through the renewable energy it generates.

The CEE device is a wave energy device for producing clean electricity. In addition, it has been designed to protect the coast from erosion. It takes an old technology (the Savonius rotor) and deploys it in a novel and efficient way. Relatively small devices of 6-10m in width will be strung together in arrays, 50-100m offshore, and will take energy from both waves and tidal movements. These arrays are deployed below the high water mark to minimise their visual impact. The coastal protection element works because the reduced speed of water will cause shoreline accretion of sediment which will in turn create stable bays (as seen at Sea Palling in Norfolk).
