Selection and characterization of recycled materials for sensible thermal energy storage
Solar Energy Materials and Solar Cells, 2012Co-Authors: Matilde Navarro, Antoni Gil, A I Fernandez, Monica Martinez, Regis Olives, Luisa F. Cabeza, Xavier PyAbstract:Abstract Alternative low cost materials are evaluated through the valorization of by-products derived from mining and metallurgical industry for solid sensible heat based energy storage systems. They were used either as received or formulated as aggregates in mortars, and their thermal and mechanical properties were characterized. A Selection Methodology was applied in order to compare them with available materials found in the literature for applications as (STES) materials, and with materials from Cambridge Educational Software (CES) Selector database. It was demonstrated that these recycled materials have a high potential for these thermal energy storage applications.

suitability of industrial wastes for application as high temperature thermal energy storage tes materials in solar tower power plants a comprehensive review
Solar Energy, 2020Co-Authors: Hassan Agalit, N Zari, Mohammed MaaroufiAbstract:Abstract Industrial wastes were identified as potential high temperature (up to 800 °C) TES materials for application in the Hybrid solar tower power plant with decoupled combined cycles (HSTPPDCC) scheme. These wastes can be categorized as follows: (1) Slags from the metallurgical industry, and (2) Coal power plant industry solid wastes. So primarily, the Selection Methodology of these identified wastes is presented. Then, updated data about the Moroccan generation of these wastes is exhibited and targeted local industries are identified. In the second part of this work, four Moroccan representative solid wastes were considered to validate the Selection Methodology, and they are namely: Induction furnace slags (IFS) gathered from a local metallurgical industry which were experimentally investigated in a previous work; and other three solid wastes gathered from the local coal power plant industry (i.e. Coal fly ashes (CFA), Coal bottom ashes (CBA), and Coal bottom clinker (CBC)). Finally, a laboratory experimental investigation was conducted only on these three later wastes in order to assess their TES potential up to 800 °C, as IFS was already investigated in a previous work and its obtained results were reported in this paper for comparison. Thus, their thermo-physical and chemical properties were evaluated, as well as their thermal stability up to 800 °C. The obtained results are promising as all the investigated materials demonstrated good thermal energy storage properties for application in solar tower power plant (up to 800 °C at least).

Selection Methodology of Potential Sensible Thermal Energy Storage Materials for Medium Temperature Applications
'EDP Sciences', 2020Co-Authors: Soukaina Hrifech, Hassan Agalit, El Ghali Bennouna, Abdelaziz MimetAbstract:Thermal energy storage (TES) component improves the revenue of a concentrating solar power (CSP) plant by allowing more heat to be stored and making the electric energy available during the absence of sunlight. The heat can be stored in three ways (sensible, latent, or thermochemical). The present work aims to identify and select cost-effective sensible TES systems suitable for the medium temperature range (100-300 °C) applications (e.g. Fresnel CSP plants, industrial waste heat recovery, etc.). Based on a literature review, a Selection Methodology is developed to select potential candidate solid TES media (e.g. natural rock, concrete, sand, etc. ) as filler material in direct or indirect contact with thermal oil, which is used generally as heat transfer fluid (HTF) for this temperature range. The main criteria and steps of this Selection Methodology are identified and they take into account the different decisive storage properties as thermo-physical and mechanical properties of the solid media. Finally, the potential candidate TES materials are identified for the targeted application and further indoor experimental investigations are briefly presented

Development of a risk assessment Selection Methodology for asset maintenance decision making: An analytic network process (ANP) approach
International Journal of Production Economics, 2015Co-Authors: Peter Chemweno, Adriaan Van Horenbeek, Peter N. Muchiri, Liliane PintelonAbstract:Risk assessment performs a critical decision support role in maintenance decision making. This is through assisting maintenance practitioners systematically identify, analyze, evaluate and mitigate equipment failures. Often, such failures are mitigated through formulating effective maintenance strategies. In asset maintenance, well-known risk assessment techniques include the Failure Mode and Effect Analysis (FMEA), Fault Tree Analysis (FTA), and Bayesian Networks (BN). In recent years, considerable research attention has been directed towards improving existing techniques, often at the expense of a structured framework for selecting suitable risk assessment techniques. Often, several criteria influence the Selection process. Moreover, the criteria are closely linked to specific organizational competencies that vary from one firm to another. In this study, a Selection Methodology for risk assessment techniques in the maintenance decision making domain is proposed. In the Methodology, generic Selection criteria for the FMEA, FTA and BN are derived based on the risk assessment process outlined in the ISO 31000:2009 standard. The criteria are prioritized using the Analytic Network Process (ANP), taking into account the judgment and opinion of academic and industrial domain experts. The results illustrate the usefulness of the proposed Methodology towards assisting maintenance practitioners discern important competencies relevant to the specific technique and as such select the technique best suited for the organization.

identification of suitable storage materials for solar thermal power plant using Selection Methodology
Applied Thermal Engineering, 2017Co-Authors: Rachid Tiskatine, Ahmed Aharoune, Lahcen Bouirden, Ahmed IhlalAbstract:Abstract Due to the intermittent nature of solar energy, there is a need to store heat to meet the needs when solar light is not available. Rock bed using air as heat transfer fluid (HTF) is being now used for thermal energy storage (TES) in concentrated solar power (CSP) plants. It is considered as a cost effective storage system. However, no detailed works have been published on Selection and identification of rocks for high temperature storage applications. The scope of the present study is to choose the most suitable rocks for high temperature sensible heat storage (SHS) using a Methodology based on laboratory measurements. Thus, experimental characterization of several rock types has been performed. An experimental device has been made for thermal conductivity measurement at room temperature. The obtained results show that the gabbro rock is the best candidate material for CSP plants. Comparative study with some other conventional materials found in literature indicates that rock is an efficient filler material for high temperature TES. From the obtained results and correlations, a second Selection Methodology has been proposed in order to minimize the steps of Selection using simple and few tests.
