“…Reviews on solar TES in building heating and cooling supply are available (Lee 2010;Novo et al 2010). The principal methods available for seasonal storage of solar thermal energy are provided by Pinel et al (2011), concentrating on residential scale systems, particularly existing examples which mostly store energy in the form of sensible heat, and briefly discussing newer methods such as chemical and latent storage. A good example of systems utilizing TES in solar buildings is the Drake Landing Solar Community in Okotoks, Fig.…”

The status and needs relating to the optimal design of community seasonal energy storage are reported. Thermal energy storage research has often focused on technology development and integration into buildings, but little emphasis has been placed on the most advantageous use of thermal storage in community energy systems. Depending on the composition and characteristics of a community, the most appropriate community thermal storage may differ from that for a single building. District energy systems usually link thermal users to cold supplies and/or heat supplies (e.g., solar thermal energy, geothermal energy from ground-source heat pumps or geothermal hot zones, industrial waste heat, thermal energy from cogeneration or trigeneration). It is demonstrated that the optimal integration of these technologies can be enhanced through the use of appropriate seasonal thermal energy storage and that community-level seasonal storage can facilitate the development of smart net-zero energy buildings and yield efficiency, economic and environmental benefits. Issues that need to be resolved to allow optimal solutions to be attained are described. Advanced tools are required for modeling, simulation, analysis, improvement, design and optimization, which incorporate advanced methods like exergy analysis. The most appropriate scale, number and type (e.g., sensible, latent, thermochemical) of thermal storages in a community need to be better assessed, and the appropriate time duration capacities for each determined in an optimal manner. This is particularly important since a combination of short-, medium-and long-term storage is sometimes required to yield the most benefits from community energy systems.

“…According to the Darcy's law and assuming an unidirectional flow, in a steady state, and Δp << p, the equivalent permeability is defined as: (7) With Ω the cross section of the bed, the total thickness of the whole set including the perforated supports and the salt bed, and Z sh = 24 mm the thickness of the three successive perforated supports. Blank experimentations without salt allow to determine the equivalent permeability of the perforated supports: k sh = 1.55.10 -8 m 2 . By an electrical analogy with two flow resistances in series, the permeability of the salt bed (at the reaction advancement X) is expressed as: …”

“…The thermal energy storage can be classified in three storage mechanisms: based on sensible heat, latent heat, and thermochemical processes. There are several studies about seasonal storage for residential applications with these different mechanisms [2,3]. Nevertheless, the thermochemical storage takes advantage of a high storage density (about 200 to 500 kWh.m -3 ), and negligible heat losses between the storage period and the recovery period because the energy is stored as chemical potential, and the sensible heat of the elements is weak.…”

Abstract:This paper focuses on the characterization and modeling of a solid/gas thermochemical reaction between a porous reactive bed and moist air flowing through it. The aim is the optimization of both energy density and permeability of the reactive bed, in order to realize a high density thermochemical system for seasonal thermal storage for house heating application. Several samples with different implementation parameters (density, binder, diffuser, porous bed texture) have been tested. Promising results have been reached: energy densities about 430-460 kWh.m -3 and specific powers between 1.93 and 2.88 W.kg -1 of salt. A model based on the assumption of a sharp reaction front moving through the bed during the reaction was developed. It has been validated by a comparison with experimental results for several reactive bed samples and operating conditions. Keywords:Thermochemical process, seasonal thermal storage, sharp front model, high-density reactive salt, permeability.

a b s t r a c tThis paper provides a solution for managing excess heat production in trigeneration and thus, increases the power plant yearly efficiency. An optimization model for combining biomass trigeneration energy system and pit thermal energy storage has been developed. Furthermore, double piping district heating and cooling network in the residential area without industry consumers was assumed, thus allowing simultaneous flow of the heating and cooling energy. As a consequence, the model is easy to adopt in different regions. Degree-hour method was used for calculation of hourly heating and cooling energy demand. The system covers all the yearly heating and cooling energy needs, while it is assumed that all the electricity can be transferred to the grid due to its renewable origin. The system was modeled in MatlabÓ on hourly basis and hybrid optimization model was used to maximize the net present value (NPV), which was the objective function of the optimization. Economic figures become favorable if the economy-of-scale of both power plant and pit thermal energy storage can be utilized. The results show that the pit thermal energy storage was an excellent option for storing energy and shaving peaks in energy demand. Finally, possible switch from feed-in tariffs to feed-in premiums was assessed and possible subsidy savings have been calculated. The savings are potentially large and can be used for supporting other renewable energy projects.
