overview of large scale Underground energy storage technologies for integration of renewable energies and criteria for reservoir identification
Journal of energy storage, 2019Co-Authors: Catarina R Matos, Julio Carneiro, Patricia Pereira Da SilvaAbstract:Abstract The increasing integration of renewable energies in the electricity grid is expected to contribute considerably towards the European Union goals of energy and GHG emissions reduction. However, it also brings new challenges for the grid. Large-scale energy storage can provide means for a better integration of renewable energy sources, balancing supply and demand, increasing energy security, enhancing a better management of the grid and also allowing convergence towards a low carbon economy. One way to ensure large-scale energy storage is to use the storage capacity in Underground Reservoirs, since geological formations have the potential to store large volumes of fluids with minimal impact to environment and society. There are several technologies which can be viable options for Underground energy storage, as well as several types of Underground Reservoirs can be considered. The Underground energy storage technologies for renewable energy integration addressed in this article are: Compressed Air Energy Storage (CAES); Underground Pumped Hydro Storage (UPHS); Underground Thermal Energy Storage (UTES); Underground Gas Storage (UGS) and Underground Hydrogen Storage (UHS), both connected to Power-to-gas (P2G) systems. For these different types of Underground energy storage technologies there are several suitable geological Reservoirs, namely: depleted hydrocarbon Reservoirs, porous aquifers, salt formations, engineered rock caverns in host rocks and abandoned mines. Specific site screening criteria are applicable to each of these reservoir types and technologies, determining the viability of the reservoir itself, and of the technology for that site. This paper presents a review of the criteria applied to identify suitable technology-reservoir couples.

electrodialysis of brackish water powered by photovoltaic energy without batteries direct connection behaviour
Desalination, 2007Co-Authors: Juan Manuel Ortiz, Vicente Garciagarcia, Eduardo Expósito, F. Gallud, Vicente Montiel, Antonio AldazAbstract:Abstract The shortage of drinking water is a major problem in the South East of Spain. In these areas, it is essential to make use of water from Underground Reservoirs, most of which are over exploited and suffer from saline contamination given their proximity to the sea. The desalination of brackish water by electrodialysis is a useful method for obtaining low cost drinking water. Photovoltaic energy can be used to power the electrodialysis system in remote areas in a reliable and autonomous way. Moreover, the photovoltaic array can be connected directly to the electrodialyzer, that is without batteries. Thus, the environmental threat of improper battery disposal is eliminated and increases the sustainability of the process. The aim of our paper is i) to demonstrate the feasibility of the desalination of brackish water by means of an electrodialysis system powered directly by photovoltaic solar panels, and ii) to explain theoretically the interaction between the photovoltaic generator and the electrodialysis system during the process. These systems are appropriate for small applications in isolated locations with lack of electric grid, where it is not necessary to produce water continuously and the volume of daily treated water required is small — about 1–10 m3.

photovoltaic electrodialysis system for brackish water desalination modeling of global process
Journal of Membrane Science, 2006Co-Authors: Juan Manuel Ortiz, Vicente Garciagarcia, Eduardo Expósito, F. Gallud, Vicente Montiel, Antonio AldazAbstract:Abstract The shortage of drinking water is a major problem in the South East of Spain. In these areas, it is essential to make use of water from Underground Reservoirs, most of which are over exploited and suffer from saline contamination given their proximity to the sea. The desalination of brackish water is a means of obtaining low cost drinking water. The method of desalination designed in this paper uses an electrodialysis system fed by photovoltaic modules that is simple, reliable, and low cost because it does not include battery storage or a battery regulator. These systems are of particular interest for isolated zones with access to wells of brackish water where connection to the electric grid is not possible. In this paper, the feasibility of the desalination of brackish water using an electrodialysis system powered by photovoltaic energy and the influence of experimental parameters has been studied. Likewise, a mathematical simulation model that allows predicting and simulating the functioning of a system of these characteristics under different meteorological conditions has been developed. The model has been applied with satisfactory results to the desalination of a NaCl solution in different experimental conditions. Data given by the mathematical simulation model was contrasted with experimental results in order to compare the reliability of the model, and good agreement was obtained. The application of this model allows the design of an electrodialysis system powered by photovoltaic energy (electrodialyzer size and the number and configuration of the PV modules), for the desalination of brackish water, as well as the study of its behaviour in different geographical locations.

brackish water desalination by electrodialysis batch recirculation operation modeling
Journal of Membrane Science, 2005Co-Authors: Juan Manuel Ortiz, J A Sotoca, Vicente Garciagarcia, Eduardo Expósito, F. Gallud, Vicente Montiel, Antonio AldazAbstract:Abstract The shortage of drinking water is a major problem in the South East of Spain. In these areas, it is essential to make use of water from Underground Reservoirs, most of which are over exploited and suffer from saline contamination given their proximity to the sea. The desalination of brackish water is a means of obtaining low cost drinking water. Electrodialysis is a technique based in the transport of ions through selective membranes under the influence of an electrical field. This technique has proved its feasibility and high performance in the desalination of brackish water, the desalting of amino acids and other organic solutions, effluent treatment and or recycling of industrial process streams and salt production. In this paper, a mathematical model for the desalination of brackish water through controlled potential electrodialysis has been developed. The application of this model allows: (i) to predict the behaviour of the system, (ii) to calculate the electrical energy consumption and (iii) to calculate the necessary time for successful desalination. The model has been applied with satisfactory results to the desalination of a NaCl solution in different experimental conditions. The model developed could be applied to commercial electrodialyzers (pilot/industrial plant) working in batches with recirculation and controlled potential, which is the usual mode of operation of such equipment when the requirements for treated water are moderated.
