Revisiting the BaO2/BaO redox cycle for solar thermochemical energy storage.

A J Carrillo et al.

Physical chemistry chemical physics : PCCP, 18(11), 8039-8048 (2016-03-01)

The barium peroxide-based redox cycle was proposed in the late 1970s as a thermochemical energy storage system. Since then, very little attention has been paid to such redox couples. In this paper, we have revisited the use of reduction-oxidation reactions
