Does changing particulate deposition affect solar power production efficiency?
However, the effect of changing particulate deposition onto solar panel surfaces on solar power production efficiency (i.e., soiling) has not been studied. We therefore characterize probabilistic outcomes across multiple climate models and scenarios.
Does the operating temperature affect the carbonization process?
As expected, the HTC operating temperature has a positive effect on the carbonization process. Elemental C increases along with a decrease in O, reaching values of 69.2 and 19.4% (at 250 °C), respectively. H and N do not vary significantly among the tests, while the presence of sulfur is almost negligible (0.3–0.4%).
How does a concentrated solar reactor work?
Through the proposed system, concentrated sunlight is converted into heat, which fully covers the thermal energy requirements of HTC and avoids the need for any external energy source. The coupling between the two technologies is direct, meaning that the reactor is directly illuminated and heated by the concentrated solar radiation.
What are the components forming a solar energy system?
Technical details of the components forming the system (i.e. the HTC reactor and the parabolic dish concentrator) were provided. Particular attention was paid to the characterization of the coating, which was realized to maximize the absorption of the solar radiation.
What is the carbon content of solar hydrochar?
In particular, Basso et al. () report a carbon content in the hydrochars of 60.2, 63.6, and 69.5% (at 180, 220, and 250 °C, respectively), which implies a percentage difference with solar hydrochar lower than 1.4%. This is valid also for oxygen and hydrogen contents, as well as for hydrochar yields.
How does temperature affect the carbonization degree of hydrochars?
The effect of temperature on the carbonization degree is reflected in the energy properties of hydrochars (Table 3). Through HTC, the higher heating value (HHV) of grape seeds passes from 22.5 up to a 30.5 MJ/kg (at 250 °C).
