Very interesting stuff! They don't quantify how much energy goes into the process but imply that it is best suited to electricity-surplus situations to balance

Very interesting stuff! They don't quantify how much energy goes into the process but imply that it is best suited to electricity-surplus situations to balance the grid (e.g. near solar facilities during daytime, wind farms during windy periods, etc.) Paper: http://onlinelibrary.wiley.com/doi/10.1002/slct.201601169/full http://onlinelibrary.wiley.com/doi/10.1002/slct.201601169/fu...
