“…This type of system is representative of a solar-coupled BTES system with GSHP, and is based on the design provided by Nussbicker et al in their study in Crailshem, Germany [48]. Solar collectors collect energy when solar radiation is present, and depending upon the system demand either circulate water to meet heating demand or transport the heated fluid to the short term storage tank [30,38,39,78,94,95]. Thermal energy stored in the water tank is dispensed during the evening to meet peak demand or sent to the BTES if unneeded.…”

“…Previous studies acknowledge the push for centralized community thermal storage development, stating that the existing work on the performance of single family homes is insufficient when compared to community sized developments [50,56]. The greater development of community scale BTES technology is attributed to the scalable efficiency of solar assisted BTES technology with storage size [95]. Increasing thermal seasonal storage efficiency sponsors less grid energy draw from space heating loads because they are met with stored solar thermal energy [103].…”

Abstract:Buildings consume approximately 3 4 of the total electricity generated in the United States, contributing significantly to fossil fuel emissions. Sustainable and renewable energy production can reduce fossil fuel use, but necessitates storage for energy reliability in order to compensate for the intermittency of renewable energy generation. Energy storage is critical for success in developing a sustainable energy grid because it facilitates higher renewable energy penetration by mitigating the gap between energy generation and demand. This review analyzes recent case studies-numerical and field experiments-seen by borehole thermal energy storage (BTES) in space heating and domestic hot water capacities, coupled with solar thermal energy. System design, model development, and working principle(s) are the primary focus of this analysis. A synopsis of the current efforts to effectively model BTES is presented as well. The literature review reveals that: (1) energy storage is most effective when diurnal and seasonal storage are used in conjunction; (2) no established link exists between BTES computational fluid dynamics (CFD) models integrated with whole building energy analysis tools, rather than parameter-fit component models; (3) BTES has less geographical limitations than Aquifer Thermal Energy Storage (ATES) and lower installation cost scale than hot water tanks and (4) BTES is more often used for heating than for cooling applications.

“…The seasonal thermal energy storage (STES) systems fall back into the first category and could also be called ''long-term'' heat storage, thanks to their capability of guaranteeing a seasonal energy storage: this consists in collecting and storing the heat in the hot seasons and extracting and using it in the winter period, when the heat demand is bigger. The STES systems include several methodologies for storing the heat: these can exploit the groundwater (ATES-aquifer thermal energy storage) (Dickinson et al 2009;Paksoy et al 2000;Rosen 1999), hot water confined in steel tanks (Bauer et al 2010;Novo et al 2010) or the ground itself, being it constituted by rocks or dry or wet quaternary sediments; in this last case the connection with the ground is provided by a series of boreholes (BTES) (Fisch et al 1998). Focusing on the last type of seasonal storage, the behavior of the ground exposed to a thermal treatment is a fundamental concept.…”

“…Sweden became the first country to implement a seasonal storage, following the oil crisis of the 1980s (Ochs et al, 2009). Since then, several seasonal heating systems have been built and designed in Europe and other countries, (Schmidt et al, 2004;Paksoy et al, 2004;Wang et al, 2010;Fischa et al, 1998;Sibbitt et al, 2012; Due to heat losses, unpredictable living habits and weather condition, an auxiliary heat source is essential to cover the peak load and total heating demand during the whole heating season. A heat pump (HP) is recommended as an efficient supplementary system to be combined with seasonal storage Hesaraki and Holmberg, 2015).…”

We studied the application of a stratified seasonal hot water storage tank with a heat pump connected to medium-, low-and very-low-temperature space heat emissions for a single-family house in Stockholm, Sweden. Our aim was to investigate the influence of heat emission design temperature on the efficiency and design parameters of seasonal storage in terms of collector area, the ratio of storage volume to collector area (RVA), and the ratio of height to diameter of storage tank. For this purpose, we developed a mathematical model in MATLAB to predict hourly heat demand in the building, heat loss from the storage tank, solar collector heat production, and heat support by heat pump as a backup system when needed. In total, 108 cases were simulated with RVAs that ranged ), and various heat emissions with design supply/return temperatures of 35/30 as very-low-, 45/35 as low-, and 55/45 (°C) as medium-temperature heat emission. In order to find the best combination based on heat emission, we considered the efficiency of the system in terms of the heat pump work considering coefficient of performance (COP) of the heat pump and solar fraction. Our results showed that, for all types of heat emission a storage-volume-to-collector area ratio of 5 m 3 m À2 , with a collector area of 50 m 2 , and a height-to-diameter ratio of 1.0 m m À1 were needed in order to provide the maximum efficiency. Results indicated that for very-low-temperature heat emission the heat pump work was less than half of that of the medium-temperature heat emission. This was due to 7% higher solar fraction and 14% higher COP of heat pump connected to very-low-temperature heat emission compared to medium-temperature heat emission.
