There is an increasing amount of interest in energy storage by reversible chemical reaction. My question is which is so far the best hydrated salt and which are the possible alternatives.
I don't have the overview to give you an direct answer. Maybe the following review is of interest for you. It contains at least an extensive list of systems that are under investigation.

Dear Gianfranco,
So far, the best salt depends on the application (low, middle and high temperature) you are working on! Beside, if you intend to know with accuracy, you have to proceed to thermal characterization and analysis of different salts. Additional to what Dr. Huinink gives to you, here are two good articles:
-- N'Tsoukpoe KE, Liu H, Le Pierrès N, Luo L. A review on long-term sorption solar energy storage. Renewable and Sustainable Energy Reviews. 2009;13(9):2385-96.
-- Mauran S., Lahmidi H., Goetz V. Solar heating and cooling by a thermochemical process. First experiments of a prototype storing 60 kW h by a solid/gas reaction. Solar Energy 82 (2008) 623 - 636.
I hope those informations help you.
Cheers,
Armand Lele
The attached document I found sometime ago on the web. It is not a scientific paper, but anyway it gives a good overview of TCES and other storage materials. It has helped me a lot to get an overview of the activities going on in this field (in the world).
