Modelling of Thermal Energy Storage Systems

According to IEA, industrial heat makes up almost one-fifth of global energy consumption and constitutes majority of the direct industrial CO2 emitted each year, as the industrial heat originates from fossil-fuel combustion. In order to decarbonize the heat demand, electrification integrated with renewable sources is one of the most feasible technological solutions. Thermal energy storage can play a key role in improving the overall economics by storing excess energy during high renewable production. In this work, we studied material aspect by performing multi-physics simulations of a phase change material and system aspect by developing a system level model of a two tank molten salt storage system.
