Development and characterisation of a new MgSO4−zeolite composite for long-term thermal energy storage

Molecular dynamics study on thermal dehydration process of epsomite (MgSO4·7H2O)

“…A recent study identified epsomite (MgSO 4-7H 2 O) as one of the most promising thermo-chemical heat storage materials, [2] and subsequent studies were carried out to improve its thermal properties. [3] Epsomite is costeffective, non-toxic, non-corrosive and has a large storage capacity of 2.8 GJ/m 3 when fully dehydrated. Preliminary measurements showed that sensible heat losses only comprise about 10% of the total energy stored.…”

Anti-blocked Composite Material of MgSO4×7H2O - KAl(SO4)2×12H2O for Thermal Energy Storage

“…Because of these disadvantages, some improvements have been done to modify its property [3][4][5]. Kuznik prepared composite materials by combing zeolite and dehydrated MgSO 4 , it found that the thermal storage density of this composite reaches to 45% of the theoretical value, and its property remains unchanged after some heatingcooling cycles [6]. Song studied the supercooling phenomena of KAl(SO 4 ) 2 ·12H 2 O by means of cold fingering and adding nucleating agent.…”

Experimental investigation on a dual-mode thermochemical sorption energy storage system

“…can be employed in sorption processes for seasonal thermal energy storage [14]. Moreover, in order to improve the capacity of heat and mass transfer of sorbent, some composite sorbents made up of salts and porous materials are developed, such as zeolite/CaCl2 [15], silica gel/salt [16], expanded graphite (EG)/salt [17], form-stable composite zeolite/MgSO4 [18], etc. The related research results show that composite sorbent is a promising material for long-term solar thermal energy storage.…”
