Gravity

    What goes up, must come down. That’s the basic principle of gravity-driven renewable energy. And unlike solar, wind, tidal and geothermal sources, gravity systems are able to synchronise energy generation with periods of peak demand. This is the same approach used by hydroelectric power plants, but the social and ecological impacts have put the brakes on hydro schemes. Now Edinburgh-based company Gravitricity Ltd is planning to use abandoned mine shafts to raise and lower weights of 500 to 5,000 tonnes, generating 1MW to 20MW of power. The company also expects its energy storage solution will cost less than lithium batteries.
