Abstract(s)
A temática das alterações climáticas constitui um peso considerável nas agendas políticas e mediáticas, inclusive em Portugal e na União Europeia. Os Objetivos de Desenvolvimento Sustentável (ODS) foram estabelecidos em 2015, no âmbito da Agenda 2030 para o Desenvolvimento Sustentável, onde países de todo o globo se comprometem, entre outras, a encontrar soluções de desenvolvimento próspero e sustentável. A indústria tem um papel preponderante neste desenvolvimento, uma vez que apresenta uma quota elevada de emissão de gases com efeito de estufa para a atmosfera e, como tal, é necessário investir na descarbonização deste setor. O presente trabalho expõe precisamente uma análise técnico-económica, da implementação de um parque solar ao abrigo do programa SHIP2FAIR (Solar Heat for Industrial Process towards Food and Agro Industries Commitment in Renewables), onde se procura evoluir para uma indústria mais limpa e sustentável. O parque solar a ser instalado, composto por coletores LF-11, da autoria da Industrial Solar, recorre ao princípio de Fresnel para produção de vapor solar. Assim, existirá uma substituição direta de fonte de energia, mantendo os requisitos de vapor necessários à laboração da refinaria. Os resultados obtidos são francamente encorajadores, dada a diminuição direta da emissão de 143 ton/ano de gases com efeito de estufa, redução do consumo de 46 ton/ano de combustível fóssil e poupança em licenças de emissão. Adicionalmente, permite concluir que a integração de vapor solar nas indústrias agroalimentares não só é possível como viável, competindo com o recurso ao combustível fóssil, e indo de encontro aos objetivos ditados pela EU, que visa a neutralidade carbónica a atingir nos próximos 30 anos.
The topic of climate change has a considerable weight in the European Union’s, as well as Portugal’s, political and media agendas. The Sustainable Development Goals (SDG’s) were established in 2015 to support the 2030 Agenda for Sustainable Development, where many countries set out to find solutions to promote a better future. The industry plays an important role in this, since it’s responsible for a large sum of greenhouse gas emissions, which makes investing in the decarbonization of this sector vital. In this regard, the following work is an analysis of the technical and financial viability of the implementation of a solar park under the SHIP2FAIR program (Solar Heat for Industrial Process towards Food and Agro Industries Commitment in Renewables), which seeks to aid the generalization of more eco-friendly industrial practices. The aforementioned solar park, composed of Industrial Solar LF-11 solar collectors, relies on the Fresnel principle for solar steam production, that while meeting the steam requirements for the refinery’s operation, also increases its share of renewable energy usage. The results of this analysis are promising, as this new energy source leads to a direct reduction of 143 ton/year of greenhouse gas emissions and consumption of 46 ton/year of fossil fuels, as well as a reduction of costs associated with emission allowances. Furthermore, it could be concluded that the use of solar steam in the agri-food sector is possible, viable and a good alternative for the use of fossil fuels, therefore meeting the objectives set out by the EU to reach carbon neutrality in the next 30 years.
