Abstract

Electricity storage, like Advanced Adiabatic Compressed Air Energy Storage (AA-CAES), is a potential solution to address the problem of intermittency of renewable power sources. AA-CAES stores not only the compressed air, but also the heat released upon compression of the air, in a Thermal Energy Storage (TES) system which plays a prevailing role in the global efficiency of AA-CAES process. At IFP Energies nouvelles, we develop TES systems based on fixed bed reactors to store heat in particles.
The objective of this study is to investigate the impact of different parameters (porosity, particulate Reynolds number, presence of walls) on heat transfers within the bed thanks to different numerical approaches at different scales: at the particle scale using Particle Resolved Simulation (Fictitious Domain / Discrete Element Methods (DEM) or body-fitted approach), at a small bed of particles scale (DEM-CFD model) or at the full bed scale (Continuous Porous Media model).
