  • Porosity Effect in a Molten Salt Thermocline
    Publication . Lima, Margarida; Costa, Paula Silva
    ABSTRACT: Thermal Energy Storage (TES) is essential for solar energy applications when the demand is not in phase with the supply of Solar Energy Molten salt thermocline storage tanks and can be a low cost option for thermal energy storage in Concentrating Solar Power (CSP) systems. To analyze the dynamics of a one tank a 2D already validated with data obtained from literature (Rojas, 2013) accounts separately for filler and molten salt regions due to their different thermos-physical properties. In the tank, between hot and cold zones a temperature gradient is established. This interface zone, called thermocline, is responsible for the whole performance of the storage tank. Properties of fillers and molten salt can increase substantially the one tank efficiency by improving its stratification. This work analyses the particles size of filler in a specific set in order to account for the influence of this parameter in the performance of the storage thermocline tank. The work makes a review on the effect of the aspect ratio in the thermocline performance and ends with a mixture of the two influences.

  • Report 2023 : Portugal
    Publication . Couto, António; Simões, Teresa; Costa, Paula Silva; Estanqueiro, Ana
    ABSTRACT: In 2023, the new installed wind power capacity amounted to 159 MW. This capacity refers to overcapacity procedures, building on existing sites. Important milestones were attained by the ministerial working group created by the Portuguese government to accelerate the offshore wind market, expecting a total installed capacity of 10 GW.
