Statoil Launches Battery Storage For Offshore Wind Farm

Does it matter that you have to go a bit further inland? Most countries have unified electricity grids and in many countries grids are even integrated across borders. As such, it is no issue that the generator (an offshore wind farm) is far removed from the storage medium (a pumped hydro plant in the mountains). “Pumped hydro is a net energy user”. That presumably refers to the fact that it has a less than perfect round trip efficiency? First of all, that applies to batteries as well (though to a lesser extent, as round trip efficiency is over 90% as opposed to 75%-ish for a good pumped hydro plant). But what’s really important to realize, is that power at times of excess production has no value. Literally. Spot market prices for power often drop to close zero and on rare occasions even go negative. As such, the efficiency of a storage system is almost irrelevant from a pu...
