“…To ensure a sustainable energy strategy in Morocco, the implementation of energy storage solutions adapted to the Moroccan context is essential. As well as developing mature solutions such as PETSs and CSP storage [65] , it is time to achieve benchmarks with new technologies such as lithium batteries and storage via hydrogen [66] as part of the ambitious Power-To-X techniques in the R&D phase.…”

“…In the case of CSP plants that operate at low temperatures (i.e., between 170 and 300 • C), intermittent energy supply is overcome by using intermediate temperature systems such as power storage systems. The Research Institute for Solar Energy and New Energies (IRESEN) is currently supervising the construction of a 1 MWe CSP plant for power generation (Solar Thermal Electricity), near Benguerir (Morocco), based on linear Fresnel collectors in the solar field and Organic Rankine Cycle (ORC) technology operating on superheated cyclopentane (C 4 H 10 ) in the power block [77]. The low-cost thermocline system in direct configuration as energy storage management seems to be better than that of two-tank technology for small to medium size ORC solar power plants.…”

Harnessing renewable solar energy through different technologies is greatly dependent on the advancement of solar grade materials' science and engineering. In this article, the prominent solar energy technologies, namely solar photovoltaic and concentrated solar power and other relevant technologies, and aspects related to various solar grade materials, influence of nanomaterials on enhancement of solar energy harvest, technology-market relations, development of hybrid systems etc., are discussed. The inspiration to write this article is not only to review the existing technologies to harvest solar energy but also to highlight the pertinent and possible solutions thereof, especially from materials perspective.

“…Bassetti et al [13] found that this technique enhances the yearly performance by about 19%. In another approach, Rodriguez et al [14] found that the use of a single thermocline tank has a similar performance to a two-tank design but it has a 30% lower investment cost.…”

The objective of the present work is the study of different thermal storage systems for a solar-fed organic Rankine cycle (ORC) system that operates with parabolic trough collectors. The conventional design with sensible thermal oil storage is compared with a storage configuration with thermal oil and ceramic rocks, as well as the use of latent storage with phase change materials (PCMs) is investigated. The initial system is studied parametrically, and it is properly designed to order for the cycle to have high performance. Different organic fluids are studied in the organic Rankine cycle and different rocks are investigated as storage materials. Toluene is found to be the best candidate in the cycle and ceramic rocks are found to be the best candidate energetically and financially. The final results proved that both the thermal oil–ceramic rocks and the PCM are better technologies than the simple sensible thermal oil storage. For the design with a 180 m2 collecting area and 8 m3 storage tank volume, the thermal oil–ceramic rocks design leads to 13.89% system efficiency and net present value (NPV) to 129.73 k€, the PCM storage to 13.97% and 128.66 k€, respectively, while the pure thermal oil case leads to 12.48% and 105.32 k€, respectively. Moreover, it is useful to state that when the collecting area is varied from 160 m2 to 200 m2 with the tank volume at 8 m3, the efficiency enhancement with ceramic rocks compared to pure oil ranges from 8.99% up to 12.39%, while the enhancement with PCM ranges from 7.96% to 13.26%. For the same conditions, the NPV is improved with ceramic rocks from 18.35% to 25.79%, while with PCM from 14.17% to 25.29%.
