Several studies have illustrated the efficiency benefits associated with coupling BTES and solar collectors in smaller-scale systems. A study on an installation for a greenhouse predicted an 80% operational efficiency, with an expected payback time of 14 years (Gao, Zhao and Tang, 2015). Follow-up pilot projects could be used to test BTES designs and performance for other building and commercial applications. The integration of PCMs into water tanks to increase the energy density of domestic hot water storage is a current topic of research. Hot water/PCM hybrids have significant potential and are likely to emerge in the medium term (Mette, Kerskes and Drück, 2012). Incorporating PCMs can help to overcome challenges associated with the space constraints and the weight of traditional water tanks, which otherwise restrict their utility. As regards systems efficiency, new approaches to improve and maintain stratification and reduce system running costs are needed. Recent developments propose new methods to increase stratification, such as minimising mixing and turbulence of water entering stratified thermal store tanks (Al-Habaibeh, Shakmak and Fanshawe, 2017). Another approach is to use a smart thermostatic control strategy that enables the prediction of required water amounts, to maintain customer comfort while reacting to variations in the electricity network (Gelažanskas and Gamage, 2016). This system operates with a demand response according to consumption forecasts (Davis, 2014). Smart control systems can produce both up and down regulation, as well as increase water heater efficiency. System changes that include optimising the integration of the internal heat exchanger, internal free convection in water tanks and the heat losses due to parasitic heat convection in pipes also warrant further study to assess the potential for new designs with higher efficiencies. Several projects are being carried out that aim to take the newly commercially available small-scale sorption chillers and combine them with solar water tanks for space heating and cooling (Reda et al., 2017). A high proportion of VRE power generation creates both new opportunities and ideal conditions for the integration of SETS heaters using ceramic bricks. SETS systems have been proposed to deliver services for demand-side management, enabling the increased penetration of low-carbon energy sources (e.g. wind and PV) at both a local and national level. Several studies have simulated and optimised the use of decentralised TES with SETS heaters for renewables penetration (Ali, Ekström and Lehtonen, 2017; Di Fresco, 2018). They noted the opportunity to co ordinate these systems to embed an interconnected TES network. Latent Similar to other PCMs, the low thermal conductivity of low-temperature PCMs limits the heat transfer rate and hence hinders their wider commercial deployment. Following similar approaches as described previously, the heat transfer rate can be improved by increasing the heat transfer area with fins and designed structures, expanding the conductive matrix in which the PCM is embedded, or by adding materials of high thermal conductivity to the matrix (e.g. carbon nanotubes) (Karaipekli et al., 2017). However, most of the solutions are only tested at lab scale and there is no common approach to all eutectics. Development will focus on testing these strategies in real conditions. Currently some low-temperature systems are fully commercialised and available, but the investment cost is very high. Further studies are required to scrutinise their long-term performance and reliability at system level. Reducing the cost of individual components, as well as developing new cost-effective approaches to whole TES system design, will be key priorities. 104 INNOVATION OUTLOOKPDF Image | THERMAL ENERGY STORAGE Outlook
