In 2023, construction begins at a wastewater treatment plant in New Mexico to make nitrogen for fertilizer from biosolids using solar thermal energy, with the first production of fertilizer in 2024 Next year, a consortium led by American Infrastructure Holdings LLC that includes Solar Dynamics and Andritz Separation will build a pilot facility in Albuquerque, New Mexico to demonstrate a novel dryer technology to produce granular fertilizer from biosolids that will be powered by solar heat. Fossil fuels are used in the current methods of manufacturing nitrogen and phosphate for fertilizer: they are used to mine and grind up phosphate ...

Besides the currently mostly deployed molten salt receiver the volumetric air receiver is the only advanced receiver technology that also offers a proven, effective and scalable storage concept (FIGURE 1). In addition, the open volumetric receiver (OVR) technology has significant advantages in simplicity and robustness of operation compared to plants with molten salt receivers. With air exit temperatures of 650°C and beyond, it has the highest upper process temperature currently available, opening up the potential for using modern high-efficiency 620°C steam processes. The OVR technology has been developed to a high degree of maturity over the last two ...
