Low-Cost Materials for Heliostats
SolarPACES Conference ProceedingsFour heliostat concepts with extensive use of timber, concrete, or polymers were developed. For cost comparison, a 2 m² benchmark heliostat was designed and built with only moderate or no use of these materials.

Parametric Study and Optimization of No-Blocking Heliostat Field Layout
Energies, 2023 Generating electric power using solar thermal systems is effective, particularly for countries with high solar potential. In order to decide on a relevant location to implement the solar tower plant and develop the mathematical model of a no-blocking ...

SolarPACES Conference Proceedings, 2023 Heliostats represent a major cost share of concentrating solar power (CSP) plants with central receiver. They are essential for system efficiency and strongly influence maintenance cost and service life. Since CSP facilities require direct solar radiation, suitable installation sites can eminently be found in desert regions.

Irrigation and Drainage, EarlyView.ABSTRACT Accurate estimation of reference evapotranspiration (ET0) and crop coefficients (Kc) is critical for irrigation planning, particularly in data‐limited regions where agriculture dominates freshwater consumption. Although machine learning (ML) methods have been widely applied to ET0 and Kc estimation, most studies address these parameters ...

Concentrated Solar Combined With Hydrothermal Treatment to Unlock Lignin Graphitization Mechanisms
Global Challenges, Volume 10, Issue 7, July 2026.Advanced carbon materials such as graphitic biocarbons are successfully obtained from kraft lignin. A sustainable production route is highlighted using a combination of hydrothermal carbonization and solar carbonization, leading to the production of long and well‐stacked graphene layers in the biocarbon.
