Abstract:
Sorption method of Thermal Energy Storage (STES) is a promising technology towards efficient use of
solar energy. Materials based on hygroscopic salts and their hydrates have a high potential for STES in
term of energy storage density. This work addresses the novel composite sorbents based on Multi-Wall
Carbon Nanotubes (MWCNT) impregnated with three hygroscopic salts selected for STES. The paper
consists of three parts: (1) analysis of operating conditions of two selected STES cycles, namely long-term
(seasonal) heat storage for the regions with moderate cold climate (LT), and short-term (daily) heat
storage in winter for areas with relatively warm climate (ST); (2) preparation of the Salt/MWCNT composites
(salt¼CaCl2, LiCl, and LiBr) adapted to these cycles, and study of water and methanol sorption on
these materials; and (3) evaluation of heat storage capacity of the new sorbents and feasibility of the
selected STES cycles. The results obtained show that the working pair “LiCl/MWCNT – methanol” appears
to be the most advantageous for the LT cycle, while “LiCl/MWCNT – water” is the best for the ST cycle. The
heat storage capacity of LiCl/MWCNT under conditions of the considered cycles reaches 1.6 and 1.7 kJ/g
(or 445 and 470 W h/kg) with methanol and water, respectively, and exceeds the appropriate values for
common and innovative adsorbents suggested for STES. This demonstrates the great potential of the new
composites for STES and promotes the broader implementation of this emerging technology
