Energy storage (IST year 2)

Module description

To provide to the students, the fundamentals necessary to understand the working principles of the most important energy storage technologies, including thermal, chemical, mechanical, magnetic and electromagnetic, hydropower, biomass synthetic fuels and electrochemical storage. To evidence the most recent developments on the integration of energy storage technologies and solutions in sustainable energy production and management from conventional and from renewable sources. To provide the tools for the design, planning and implementation of energy storage solutions.

The current energy scenario. Introduction historical context and energy storage interest. Basic concepts of Thermodynamics. Fundamental notions of Transport
Phenomena. Energy storage based on phase changes and chemical reactions. Phase equilibrium; latent heat and sensible heat; Rule phases; Phase equilibria of pure systems and mixtures thereof; eutectic, peritectics and azeotropic systems (gasliquid). Thermal effects of chemical reactions. Applications. Energy storage in organic substances. The production of fuels as an energy storage medium. Production of liquid and gaseous fuels (including hydrogen) from biomass. Mechanical energy storage. Hydroelectric dams, potential energy storage in dams. Basics of electrochemical storage. Electromagnetic energy storage Condensers, types of capacitors, operating mechanism and storage. Superconductor drivers, operating mechanism and storage. Applications. Electrochemical energy storage. Different generations and types of batteries. Double layer supercapacitors, Faradaic and asymmetrical. Hybrid systems (banks batteries / supercapacitors). Charge storage capacity and charge and discharge cycles. Ragone relationships and their interpretation. Applications in production of conventional and renewable energy systems, electric mobility, transport, smart grids and efficient buildings. Lifecycle analysis, including recycling of batteries and supercapacitors and sustainability in their reconversion or elimination. Future prospects solar and wind energy storage and energy storage for the propulsion of vehicles, network integration and smart cities; electric mobility and consumer electronics.
