Rock bed thermal energy storage coupled with solar thermal collectors in an industrial application: Simulation, experimental and parametric analysis

Thermo‐physical characterisation of natural rocks and impact analysis of variations in their thermo‐physical properties on thermal storage performance

“…Currently, the world is seized with the challenge of global warming and climate change, which have caused serious disasters on the globe. 3 This has presented an opportunity for solar thermal technologies as an attractive alternative source of sustainable thermal energy for industrial purposes, as reported by Muhammad et al 4 The capacity utilisation of solar thermal systems is still limited due to various hindrance factors, including the discontinuous nature of the solar thermal resource. 5 This has triggered several research activities on thermal energy storage (TES) technologies over the past years.…”

Design Optimization of an Innovative Layered Radial-Flow High-Temperature Packed Bed Thermal Energy Storage

“…1(a), is the most mature solution and it has been deeply investigated both numerically [6,7], and experimentally [8][9][10]. Different solid materials (such as natural rocks [11], steel slags [12], and commercial ceramics as Al 2 O 3 [13,14] or ZrO 2 [15]), working temperatures (with the largest operational range of 100 • C -900 • C [16]), and HTFs (such as thermal oil [17], molten salts [18,19], air [9,20] and CO 2 [21]) have been considered. This PBTES design offers good thermal stability and limited thermocline degradation, leading to thermal efficiency higher than 90 % [7].…”
