Abstract [en]

In Europe, 40% of the total energy use originates from the building sector and amounts to 36% of Europe’s Greenhouse Gas (GHG) emission (European Commission, 2013). With the smart use of a Phase Change Material (PCM) integrated Mobile Thermal Energy Storage (M-TES), industrial surplus heat may be transported to a District Heating (DH) network for building space heating and domestic hot water supply. Here, 2D and 3D numerical models were constructed for the design analysis of a latent heat (LH) M-TES. Thermal power performance is shown to be a tradeoff to storage capacity and varies exponentially to the shell and tube’s pitch to diameter ratio (PDR). For a fixed PDR configuration, the performance curve varies nonlinearly. Operating strategy with partial charge is shown to provide high thermal power when the demand arises, reducing thus the additional capital expenditure for extra tailor designed M-TES units. Partial storage is an essential control strategy for reaching economic sound mobile energy storage solution.
