A Comprehensive Review of Thermal Energy Storage
sustainability Review A Comprehensive Review of Thermal Energy Storage Ioan Sarbu * ID and Calin Sebarchievici Department of Building Services Engineering, Polytechnic University of Timisoara, Piata Victoriei, No. 2A, 300006 Timisoara, Romania; [email protected] * Correspondence: [email protected]; Tel.: +40-256-403-991; Fax: +40-256-403-987 Received: 7 December 2017; Accepted: 10 January 2018; Published: 14 January 2018 Abstract: Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation. TES systems are used particularly in buildings and in industrial processes. This paper is focused on TES technologies that provide a way of valorizing solar heat and reducing the energy demand of buildings. The principles of several energy storage methods and calculation of storage capacities are described. Sensible heat storage technologies, including water tank, underground, and packed-bed storage methods, are briefly reviewed. Additionally, latent-heat storage systems associated with phase-change materials for use in solar heating/cooling of buildings, solar water heating, heat-pump systems, and concentrating solar power plants as well as thermo-chemical storage are discussed. Finally, cool thermal energy storage is also briefly reviewed and outstanding information on the performance and costs of TES systems are included. Keywords: storage system; phase-change materials; chemical storage; cold storage; performance 1. Introduction Recent projections predict that the primary energy consumption will rise by 48% in 2040 [1]. On the other hand, the depletion of fossil resources in addition to their negative impact on the environment has accelerated the shift toward sustainable energy sources. -

Criteria have been selected based on relevance and simplicity. When values can not be assessed for storage techniques to new to be fully developped, we used more qualitative data. Comparing systems is always a very hard task. Boundary conditions and all paramaters must be comparable. This is very difficult to achieve when 9 analysts work around the world on similar systems but with different storage units. This report is an attempt of a comparison. Main generic results that we can draw with some confidency from the inter comparison of systems are: - The drain back principle increases thermal performances because it does not use of a heat exchanger in the solar loop and increases therefore the efficiency of the solar collector. -
Solar Thermal Collector Component for High-Resolution Stochastic Bottom-Up Domestic Energy Demand Models
322: Solar Thermal Collector Component for High-resolution Stochastic Bottom-up Domestic Energy Demand Models Paul H ENSHALL , Eoghan M CKENNA , Murray THOMSON , Philip E AMES Centre for Renewable Energy Systems Technology (CREST), School of Electronic, Electrical and Systems Engineering, Loughborough University, LE11 3TU, UK. [email protected] High-resolution stochastic ‘bottom-up’ domestic energy demand models can be used to assess the impact of low- carbon technologies, and can underpin energy analyses of aggregations of dwellings. The domestic electricity demand model developed by Loughborough University has these features and accounts for lighting, appliance usage, and photovoltaic micro-generation. Work is underway at Loughborough to extend the existing model into an integrated thermal-electrical domestic demand model that can provide a suitable basis for modelling the impact of low-carbon heating technologies. This paper describes the development of one of the new components of the integrated model: a solar thermal collector model that provides domestic hot water to the dwelling. The paper describes the overall architecture of the solar thermal model and how it integrates with the broader thermal model, and includes a description of the control logic and thermal-electrical equivalent network used to model the solar collector heat output. Keywords: Solar thermal collector, domestic, energy demand, dynamic. 14 th International Conference on Sustainable Energy Technologies – SET 2015 25 th - 27 th of August 2015, Nottingham, UK 1. INTRODUCTION Urban areas currently use over two-thirds of the world’s energy and account for over 70% of global greenhouse gas emissions (International Energy Agency 2008). Furthermore, increasing urbanisation means that the proportion of the population living in urban areas is expected to rise from around 50% today to more than 60% in 2030, with urban energy use and emissions expected to rise as a consequence. -

Received: 21 August 2012; in revised form: 26 September 2012 / Accepted: 8 October 2012 / Published: 16 October 2012 Abstract: The reduction of electricity use for heating and domestic hot water in cold climates can be achieved by: (1) reducing the heating loads through the improvement of the thermal performance of house envelopes, and (2) using solar energy through a residential solar-based thermal storage system. First, this paper presents the life cycle energy and cost analysis of a typical one-storey detached house, located in Montreal, Canada. Simulation of annual energy use is performed using the TRNSYS software. Second, several design alternatives with improved thermal resistance for walls, ceiling and windows, increased overall air tightness, and increased window-to-wall ratio of South facing windows are evaluated with respect to the life cycle energy use, life cycle emissions and life cycle cost. The solution that minimizes the energy demand is chosen as a reference house for the study of long-term thermal storage. -

Prof. Dr. Halil Z. Alibaba2 1, 2Department of Architecture, Eastern Mediterranean University, Gazimagusa, TRNC, Via Mersin 10, Turkey Abstract: The utilisation of alternative energy in buildings are getting closer to being a basic process in the construction of projects with the need of having sustainable building outlines with energy efficiency and expanding the exploration and utilisation of renewable energy sources in the industry with examples in solar energy, wind energy and geothermal energy. Solar thermal systems have turned into alternatives in the energy efficiency of current buildings, therefore less energy expending buildings, utilising the solar energy as an alternative in process are increasing and this has a tendency to give answers for energy issue which furthermore increase the lifecycle and decrease the upkeep of the buildings in general. Solar thermal systems integration in buildings have increased the performance through utilizing most building components and envelope for the generation of energy or reduction of its use which are the use of mounting solar panels ,integration of PV in windows, facade and roof of buildings. For better understanding, this paper will compare some institutional buildings which use solar collector integrated facades, analyse the methods of application on façade, efficiency of the generation and a critic of the general use of solar collectors integrated facades. The final result of this work will help and encourage designers on specifications and integration techniques and know-how of which method of integration is best suited to be used on their building projects. -
