Natural Hydrogen Prospectivity in Portugal: A first approach

ABSTRACT: This works presents the first maps of the prospectivity of natural hydrogen in continental Portugal and the methodological approach undertaken. The methodology used in this study follows the Chance of Sufficiency (COS) approach, which is also sometimes referred as the Chance of Success in exploration geoscience. It is a probabilistic estimate of whether a geological prospect contains a resource (e.g.,...

Estudos Geofísicos na Perspetiva de Otimização do Local de uma Captação Geotérm...

RESUMO: As alterações climáticas têm gerado impactos significativos nos territórios termais, tanto de forma direta, por diminuição, desde logo, da recarga dos sistemas aquíferos, e indiretamente através da intensificação da procura de recursos hídricos subterrâneos e da transformação dos usos do solo, fatores que, em conjunto, podem comprometer a qualidade e a disponibilidade dos recursos hidrominerais e geotér...

Hydrogen storage in Portugal

ABSTRACT: This Policy Brief provides an overview of the technologies and challenges associated with hydrogen storage, a fundamental link in the hydrogen value chain. Portugal reached an electricity share of about 70% from renewable energy sources in 2023 (APREN, 2024). It is an outstanding historical achievement. The electricity share from wind energy was 27.3%, followed by hydropower generation with 24.7%, sol...

Armazenamento de hidrogénio em Portugal

RESUMO: Este Policy Brief fornece uma visão geral das tecnologias e desafios associados ao armazenamento de hidrogénio, um elo fundamental na cadeia de valor do hidrogénio. Portugal atingiu uma quota de eletricidade de cerca de 70% proveniente de fontes de energia renováveis em 2023 (APREN, 2024). Trata-se de um feito histórico sem precedentes. A quota de eletricidade proveniente da energia eólica foi de 27,3%,...

CO-2 FOGO NO BLOCO: SIMULAÇÃO MULTIDISCIPLINAR IN SITU EM EMERGÊNCIA NÃO MÉDICA

Introdução e Objetivos: A simulação in situ  possibilita o treino de profissionais de saúde,  melhorando a prestação de cuidados, em particular, perante situações que exijam o desempenho rápido e coordenado de uma equipa multidisciplinar1,2. Este trabalho teve como objetivo rever o plano de emergência interna (PEI) perante um cenário de incêndio no bloco operatório (BO) e identificar e promover as ações corre...

Analysis of the geological control on the spatial distribution of potentially t...

ABSTRACT: The distribution of the high concentrations of arsenic (As) and fluoride (F-) in groundwater on a Pan-European scale could be explained by the geological European context (lithology and structural faults). To test this hypothesis, seventeen countries and eighteen geological survey organizations (GSOs) have participated in the dataset. The methodology has used the HydroGeoToxicity (HGT) and the Baselin...

Characterization of thermal and acoustic insulation of chicken feather fibre re...

This work evaluates the application potential of chicken feather fibres in the reinforcement of polymeric materials, particularly thermosetting ones as epoxy resins. Due to the morphology of this type of protein fibres, which is characterized by being hollow, its study and application has particular interest as components being able to contribute for the thermal insulation, once air is well known as a bad heat ...

Deep Geological Conditions and Constrains for CO2 Storage in the Setúbal Penins...

This paper describes the research conducted in order to identify potential CO2 storage reservoirs in the Setúbal Peninsula, Portugal. The studied area is located in the southern sector of the Lusitanian Basin, the largest Portuguese Mesozoic sedimentary basin. Data from deep geological conditions was collected from oil and gas exploration wells and structural maps of the target geological horizons were processe...

Sustentabilidade ambiental: discutindo o lugar

Based on the assumption that, in essence, capitalist and socialist development models do not seek environmental sustainability, this papers has sought to perform an analysis displaying the site associated with the notion of local development based on the discussion of sustainable management and development.; Partindo do pressuposto de que os modelos de desenvolvimento capitalista e socialista não buscam, na ess...
