The latent heat was shown to increase by 230%, from 12 to 28 Jg-1 (183.1 MJm-3) for the solution annealed material. As shown by the DSC results in Figure 2b, 1-octadecanol has an endothermic transformation near 60 ̊C, reverse transformation near 46 ̊C, and a mass-specific latent heat of 225 kJkg-1 (182.25 MJm-3).
The requirement for primary frequency regulation (PFR) capability of thermal power plants (TPPs) in power systems with larger penetration of renewable energy resources (RESs) is higher since the RESs contribute less to PFR compared with TPPs. To ensure the system frequency stability, this paper proposes to enhance the PFR capability of TPPs through …

Under the solid-solid phase change mechanism, the transformation of materials from a crystalline form to an amorphous state is responsible for thermal energy storage or release. Solid-solid PCMs normally have no leakage issues encountered by solid-liquid PCMs but have relatively low latent heat [ [72], [73], [74] ].
These three types of TES cover a wide range of operating temperatures (i.e., between −40 C and 700 C for common applications) and a wide interval of energy storage capacity (i.e., 10 - 2250 MJ / m 3, Fig. 2), making TES an interesting technology for many short-term and long-term storage applications, from small size domestic hot water …
