Special Issue Information

Dear Colleagues,

The journal Energies (ISSN 1996-1073, IF 2.702) is currently running a Special Issue entitled “Concentrating Solar Power Systems” and, thanks to your expertise in the field, we think that you can make an excellent contribution to this Special Issue.
The decabonization of the global energy system is recognized as a fundamental action to limit global warming, and for this purpose, energy transition toward renewables will play a key role. Among renewables, concentrating solar power (CSP) is recognized as a viable solution to replace fossil fuels in regions characterized by high solar radiation. Concentrated solar power can be used in conventional power cycle for electricity generation or can provide heat at low (around 100 °C), medium or high temperature (>1000 °C) for several industrial processes, water desalination, solar fuel production, etc.
In recent years, the growing interest in the CSP tehcnologies has led to an intense research activity in various topics such as concentrators, thermal receivers, advanced power cycles, thermal energy storage, measurement techniques, O&M optimization, simulation tools, etc.
This Special Issue of Energies on “Concentrating Solar Power Systems” intends to capture the latest research in the field of Concentrating Solar Power ranging from original research papers to reviews and case studies. In this sense, papers that are characterized by the listed keywords may be submitted.

Reversible Molten Catalytic Methane Cracking Applied to Commercial Solar-Thermal Receivers
Energies 2020, 13(23), 6229; https://doi.org/10.3390/en13236229 - 26 Nov 2020
Abstract

To design solar methane crackers, a canonical plug flow reactor model was developed that spanned industrially relevant temperatures and pressures (1150–1350 Kelvin and 2–200 [...] Read more.
When driven by sunlight, molten catalytic methane cracking can produce clean hydrogen fuel from natural gas without greenhouse emissions. To design solar methane crackers, a canonical plug flow reactor model was developed that spanned industrially relevant temperatures and pressures (1150–1350 Kelvin and 2–200 atmospheres). This model was then validated against published methane cracking data and used to screen power tower and beam-down reactor designs based on “Solar Two,” a renewables technology demonstrator from the 1990s. Overall, catalytic molten methane cracking is likely feasible in commercial beam-down solar reactors, but not power towers. The best beam-down reactor design was 9% efficient in the capture of sunlight as fungible hydrogen fuel, which approaches photovoltaic efficiencies. Conversely, the best discovered tower methane cracker was only 1.7% efficient. Thus, a beam-down reactor is likely tractable for solar methane cracking, whereas power tower configurations appear infeasible. However, the best simulated commercial reactors were heat transfer limited, not reaction limited. Efficiencies could be higher if heat bottlenecks are removed from solar methane cracker designs. This work sets benchmark conditions and performance for future solar reactor improvement via design innovation and multiphysics simulation. Full article

Small-scale hybrid parabolic dish concentrated solar power systems are a promising option to obtain distributed electricity. During the day, solar energy is used to produce electricity, and the absence of sunlight can be overwhelmed with fuel combustion. This study presents a thermo-economic survey for a hybridized power plant in different regions of Spain, considering the local climatic conditions. The developed model considers the instant solar irradiance and ambient temperature dynamically, providing an estimation of the power output, the associated fuel consumption, and the most relevant pollutant emissions linked to combustion. Hybrid and combustion-only operating modes at selected geographical locations in Spain (with different latitudes, mean solar irradiances, and meteorological conditions) are analyzed. The levelized cost of electricity indicator is estimated as a function of investment, interest rate, maintenance, and fuel consumption actual costs in Spain. Values of about 124 €/MWhe are feasible. Fuel consumption and emissions in hybrid operation can be reduced above 30% with respect to those of the same turbine working in a pure combustion mode. This model shows the potential of hybrid solar dishes to become cost-competitive against non-renewable technologies from the point of view of costs and reduction in gas emission levels in regions with high solar radiation and low water resources.
