“…An investor in such a hybrid energy system effectively acquires a 'real option' that allows for real-time optimization by either selling electricity at the current market price or converting it to hydrogen. Such flexibility is valuable in an environment in which both electricity prices and renewable power generation fluctuate over time 17,18 . Renewable hydrogen production will then be considered economically viable if investing in a combined facility has a positive net present value (NPV) and furthermore this value exceeds the NPV of the renewable energy facility on its own.…”

“…In fact, the sensitivity of levelized cost of energy from photovoltaics has been found to be highest towards the discount rate rather than energy efficiency or specific capital cost. 332 Indeed, optimistic values of 6% are found with reports of low LCH 326,330 and more conservative values of 10-12% with high LCH. [328][329] The economic feasibility of integrated and modular PEC water splitting has been directly compared in the same framework of assessment, with the former showing slight economic advantage (12.3 versus 13.1 USD/kg) because it does not require electrical interface equipment between the photovoltaic and electrolytic components.…”

“…Encouragingly, Haussener and co-workers used active thermal management for a concentrated PEC device to reach current densities of higher than 0.88 A cm -2 at STH efficiencies of above 15%, which were among the highest operating current densities at high efficiency. 325 Conduction and forced convection were employed to cool the photoabsorber that suffered from larger losses at higher temperatures, and heat up the catalytic sites, which showed smaller overpotential at higher temperatures, with the excess heat from the photoabsorber ( Figure 44) 326 The resulting model thus includes a minimally sized electrolysis plant, the capital cost of which accounts for less than 15% of the LCH in the case of PEM electrolyzer, 326 similar to the case of grid-powered electrolysis. 327 Given the intermittent nature of solar power, however, this design is impractical without a proper energy storage system to provide a stable source of electricity.…”

Solar hydrogen production from water is a sustainable alternative to traditional hydrogen production route using fossil fuels. However, there is still no existing large-scale solar hydrogen production system to compete with its counterpart. In this Review, recent developments of four potentially cost-effective pathways towards large-scale solar hydrogen production, viz. photocatalytic, photobiological, solar thermal and photoelectrochemical routes, are discussed, respectively. The limiting factors including efficiency, scalability and durability for scale-up are assessed along with the field performance of the selected systems. Some benchmark studies are highlighted, mostly addressing one or two of the limiting factors, as well as a few recent examples demonstrating upscaled solar hydrogen production systems and emerging trends towards large-scale hydrogen production. A techno-economic analysis provides a critical comparison of the levelized cost of hydrogen output via each of the four solar-to-hydrogen conversion pathways.

Abstract. Energy plays a crucial role in the economy of any country. One of the most recent trends in global development is the transition to "green” growth. Morocco is keeping pace with its growth by promising to increase renewable energy capacity to 42% of total installed capacity by 2020 and to 52% by 2030. This study develops a framework that aims to determine the optimal areas for deploying photovoltaic (PV) installation in two stages. The first stage aims at excluding the undesirable areas such as forests, rivers and agricultural land. The second stage consists in defining the suitability of sites based on seven criteria; solar irradiation, land surface temperature, slopes, slope orientation, distance from power lines, distance from main roads, distance of urban area. In this study we are using fuzzy logic and fuzzy membership functions in order to create criteria layers in the environment of Geographic Information System (GIS) that allowing the integration of a Multi-Criterion Decision Analysis (MCDA) to identify the best sites to deploy PV solar power plants in north-western Morocco. Also, the Analytic Hierarchy Process (AHP) technique is used to determine weights for each one of the criteria. Results obtained from the spatial approach shows that the major portion of the studied area was judged inappropriate for solar farms installations. Also, it shows that only 5.11% (8500 Ha) of the territory demonstrate high suitability for PV solar installations located in the southern part of our studied area with a potential of electricity generation, from the areas with high suitability level, assuming a PV system efficiency of 6.48%; equivalent to 5.39 Twh/year with an installed capacity of 4.02 GW and an annual carbon emission reduction of 3 697.54 Kt-CO2/year. The resulting suitability map can be used as a decision support tool to help the public policy makers to integrate green energy into their policies.
