Thermochemical energy storage systems have the advantage of using materials that store a high energy density with low energy losses over time compared to sensible and latent energy storage. These are important characteristics to be exploited in seasonal heat storage applications. In this work three hydrated salts were studied as potential seasonal storage materials; bischofite, carnallite A and carnallite B. The first two materials are industrial waste taken from Salar de Atacama in northern Chile, and the last one is a natural salt taken from potassium saline deposits in the south- east of Spain. The chemical characterization indicated; bischofite presents 97.4% of MgCl2∙6 H2O as active material, and carnallite A and B present 73.54% and 87.82% of KCl·MgCl2∙6 H2O, respectively. Moreover, carnallite materials were mixed with NaCl as the main impurity. Concerning the thermal study of the dehydration and hydration reaction, bischofite showed a low reversibility of 34.7% and agglomerated and hardness particles, due to its high liquidness, that was evolving into a difficult application. Regarding the material of carnallite A, a low cyclic stability was showed under conditions of PHy= 25 kPa and 100 °C and 150 °C, because a decomposition of carnallite A was identified. This problem was solved through the improvement of seasonal conditions (PHy= 1.3 kPa, THy= 40 °C, PDe= 4.0 kPa and TDe= 110 °C) to obtain a good reversibility of the reaction for 10 cycles (10 years of application). However, these optimized conditions reproduced using carnallite B, showed a 14% lower reversibility than carnallite A. This reversibility difference could be explained due to a higher percentage of NaCl present in carnallite A, which contributes as an additive material capable of decreasing the agglomeration of the particles. Along with this, a high energy density of 1,129 GJ/m3 during the tenth hydration cycle was measured to supply the energy needs of a home during winter time. All of these results highlight carnallite A as a potential material waste for seasonal heat storage applications.

In this thesis work, we develop and apply optimization techniques in energy design and management. First we focus on bilevel optimization and developed new theoretical analysis for single-leader-multi-follower games with cardinality constraints. It is then applied to optimal location of charging stations for electric vehicles. The second part is dedicated to economic optimization of solar power plants from a long term as well as from a short term perspective. Innovating global optimization approach mixing optimal design of storage and optimal operation in a market context is developed. Then at a short term scale, the optimal control of energy production of a solar power plant is analysed

Esta tesis es una contribución a generar una economía eficiente en recursos y energía por medio de reacciones químicas. En particular esta memoria presenta por una parte, un proceso rápido y eficaz para la recuperación de las sales de cromo(III) y la obtención de biopolímeros de alto valor añadido de los residuos cromados provenientes de la industria del curtido. El proceso de descromación está basado en la oxidación del cromo(III) a cromo(VI) usando peróxido de hidrógeno en medio básico. Además, la misma reacción de oxidación se ha utilizado para la recuperación de las sales de cromo(III) de los efluentes cromados. Por otra parte, las reacciones termoquímicas (procesos de adsorción química y las reacciones químicas sólido-gas) abren una nueva posibilidad para el almacenamiento térmico de energía solar por periodos largos de tiempo en zonas residenciales. Este trabajo aporta una revisión sobre la investigación experimental de sistemas de almacenamiento térmico con materiales termoquímicos (TCM). Además, la memoria presenta el trabajo realizado en la caracterización experimental de MgSO4•7H2O, Al2(SO4)3•18H2O, CaCl2•2H2O and MgCl2•6H2O para la determinación de su aplicación como TCM en un sistema estacional de almacenamiento térmico de energía solar. Los resultados experimentales indicaron que los cloruros pueden liberar calor al sistema de calefacción residencial a temperaturas más altas que los sulfatos.
The current thesis is a contribution to create energy and resource efficient economy by means of chemical reactions. In particular, the thesis presents, on one hand, a quick and effective procedure for recovery of chromium (III) salts and isolation of high added value collagenic biopolymners from chromium(III) tanned solid wastes. The dechroming process is based on the oxidation of chromium(III) to chromium using hydrogen peroxide in alkaline medium. Additionally, the same oxidation reaction was used for recovery of chromium(III) salts from tannery effluents. On the other hand, thermochemical reactions (chemical adsorption processes and solid-gas chemicals reactions) open a new way for long-term solar heat storage in residential areas. The present work gives a review of the experimental research on thermal energy storage systems with thermochemical materials (TCM). Moreover, this work describes the experimental characterisation of MgSO4•7H2O, Al2(SO4)3•18H2O, CaCl2•2H2O and MgCl2•6H2O to determine is suitability for application in a seasonal solar heat storage system. Experimental results showed that the chlorides can deliver heat to the residential heating system at a higher temperature than the sulphates.
