- A wind turbine sitting idle on a calm day or spinning swiftly when power demand is already met poses a problem for renewables, and is one researchers think can be tackled under the sea.
- When the power is needed, the pressure of the ocean squeezes the water through the system on the seafloor that includes turbines — and the result is electricity.
- FLASC, a spin-off of the University of Malta, has a system that uses renewably made electricity to pump water into a chamber that contains under-pressure air.
