The title of the article is just a bit inaccurate. Perhaps 'Why domestic energy storage sucks' would be better. The full title is in fact 'Why energy storage sucks. (but there is hope)' but the last bit is left out above. Pumped storage is great, but not in your house or for an off-grid hut in Africa. One interesting application of pumped storage is applying it to tidal power. You could build a tidal lagoon and not only get the super reliable free tidal energy but also use it as a store. Pump extra water out or in when renewable sources are producing. Then use the power when demand is high. This is covered a bit in this excellent free book: http://WithoutHotAir.com http://WithoutHotAir.com
