DESIGN AND METHODOLOGY FOR AN AGRIVOLTAIC PILOT PROJECT IN THE ALENTEJO REGION
Oliveira, Helena; Bunge, Lisa; Silva, José; Fialho, Luís; Infante, Paulo; Horta, PedroThis paper presents a study for an agrivoltaics pilot project in the Alentejo region, aimed at identifying the average percentage increase in efficiency between different types of photovoltaic panels (monofacial and bifacial modules) due to cooling effects from shading, when installed over monoculture rotations and intercropping systems with crops that benefit from Shade Avoidance Syndrome (SAS). The study will...
Optimização económica da operação de armazenamento térmico a sais fundidos com ...
Pires, Celísio; Frederico, Felizardo; Mané, Junior; Canavarro, Diogo; Malico, Isabel; Horta, PedroA biomassa lenho-celulósica apresenta-se hoje como um recurso com potenciais novos usos, nomeadamente na produção de biocombustíveis na forma líquida como o bioetanol ou o biodiesel ou biocombustíveis na forma sólida e gasosos como o carvão vegetal, o biogás ou o gás de síntese. Portugal tem cerca de 35% do seu território coberto por floresta, apresentando-se a região do Alentejo como a que apresenta a maior va...
Preliminary simulation results of a molten salt thermal storage thank for conce...
Mané, Júnior; Malico, Isabel; Domingues, Nuno; Ait El Cadi, Radia; Horta, PedroMolten salt thermal storage systems play a critical role in concentrated solar power (CSP) plants, ensuring energy storage and dispatchability. Among these, thermocline tanks offer the potential for cost reduction, compared to the standard thermal storage system implemented in CSP plants: a two-tank solution (for hot and cold fluid, individually). This paper presents initial results from a Computational Fluid D...

ASSESSMENT AND GUIDELINES FOR AN AGRIVOLTAIC PILOT IN ALENTEJO
Bunge, Lisa; Fialho, Luis; Horta, PedroThis paper presents a study of compatibility strategies for the interface of the new PV power plant of the Aquila Capital group at Cercal do Alentejo with agricultural and conservation activities, aiming at minimizing the environmental impact while engaging the local communities in the benefit of such approach. In the first phase, agricultural production and nature conservation compatibility strategies with the...
Carbon-Based Hybrid Supercapacitors for high Power Photovoltaic Irrigation
Horta, Márcia; Fialho, Luis; Foles, Ana; Horta, PedroA photovoltaic pumping system comprises the following components: a solar photovoltaic (PV) installation, a variable frequency converter, a motor-pump, and a water source. The application combines solar PV technology, hydraulic engineering, and high-efficiency water management techniques to optimize irrigated farming. In the last decades, a growing trend has been observed in the application of renewable energie...
Produtos farmacêuticos ameaçam bacias hidrográficas europeias
Novais, Maria Helena; Palma, Patrícia; Morais, Manuela; Penha, Alexandra Marchã; Fialho, Luís; Horta, PedroThe concern with the presence of pharmaceuticals and their potential impacts on aquatic ecosystems, associated with the lack of systematized information, due to legislative gaps, motivated this literature review. Published studies on pharmaceuticals’ detection and quantification in treated effluents from WWTPs and in watersheds, in Portugal, Spain, France and the United Kingdom were consulted. The transversalit...
On the comparison of parabolical and cylindrical primary mirrors for linear Fre...
Santos, André; Canavarro, Diogo; Horta, Pedro; Collares-Pereira, ManuelThe design of a linear Fresnel concentrator is challenging. One task related to the curvature design of the primary mirrors is the selection of a bent shape: parabolic or cylindrical. This article presents a new and general approach to comparing both shapes. It is based on the root mean square measure of local slope deviations as an overall metric to represent how much a cylindrical mirror deviates from the par...
Assessment of the optimal curvature radius of linear Fresnel primary mirrors
Santos, André; Canavarro, Diogo; Horta, Pedro; Collares-Pereira, ManuelThe curvature radius design of linear Fresnel primary mirrors relates to two possible configurations: non- uniform, each mirror has a particular radius value, and uniform, all mirrors have the same value. Different non-uniform designs have been proposed but never compared to understand their differences or whether these differences exist. Moreover, it is not clear how much performance loss would result from usi...
LANDSCAPE INTEGRATED PV: A CASE STUDY
Pires, Celísio; Bunge, Lisa; Fialho, Luís; Horta, PedroThis paper presents a comprehensive proposal for a photovoltaic (PV) system aimed at supplying electricity to an ecotourism project at Quinta do Carmo, Estremoz, Portugal. The analysis begins by estimating and analysing electricity consumption for three distinct categories: water pumping, buildings and accommodations, and electric vehicle charging. Based on these estimations, a PV system is sized, and energy pr...
