"Gravitricity develops winch and hoist system to store energy at half the cost of lithium-ion batteries" - Gravitricity, an Edinburgh-based startup.

I think Edinburgh has a really good startup scene with a huge bio-quarter and even some space engineering like Skyrora. Skyscanner, a flight search engine, has been the most successful so far, sold to Ctrip for 1.4b UKP.

"a typical 10MW lithium-ion battery project, capable of releasing 24MW of electricity per hour"
