Laboratory experiments and modelling of the geochemical interaction of a gabbro...
Berrezueta, Edgar; Moita, Patricia; Pedro, Jorge; Abdoulghafour, Halidi; Mirão, José; Beltrame, Massimo; Barrulas, Pedro; Araújo, AlexandreThe potential for mineral carbonation of carbon dioxide (CO2) in a plutonic mafic rock is addressed in this work through a set of laboratory experiments on a gabbro-anorthosite sample from the Torrão - Odivelas Massif (Portugal). The experiment was conducted in two stages under pressure (8 MPa) and temperature (313.15 K) conditions similar to those expected around a CO2 injection well. Stage-I simulated dissolu...
CO2 storage through mineral carbonation. Fostering ICT collaboration in innovat...
Pedro, JorgeMineral carbonation is a Research Theme (RT) align with the Scientific Challenge (SC) . “Georesources for circular economy and energy transition”, of the ICT strategy for 2025-2029 period. Mineral carbonation aims to assess CO2 emissions-reduction, to remove greenhouse gasses from the atmosphere or ocean and is aligned with the European and National policies, strategies and goals, specifically the European Gree...
Avaliação do potencial dos maciços gabróicos do Alentejo para a carbonatação mi...
Pedro, Jorge; Carneiro, Júlio; Moita, Patricia; Berrezueta, Edgar; Araújo, Alexandre; Marques, Fábio; Pinho, Catarina; Caeiro, HelenaThe InCarbon project assessed the potential of gabbroic rocks for CO2 storage in alentejo. Lab carbonation experiments were carried out on gabbroic rocks from the Sines and Odivelas massifs. After gabbroic samples exposure to supercritical CO2-rich brine inside an autoclave, for 90 days, the XRD analysis reveals the presence of dolomite on sample surface, whereas the chemical mapping, by SEMEDS, suggest a spati...

Pinho, Catarina; Carneiro, Júlio; Moita, Patricia; Pedro, JorgeO projeto InCarbon promoveu uma ação de divulgação sobre tecnologias de mitigação de alterações climáticas, na Captura e Armazenamento Geológico de CO2 (CCS – CO2 Capture and Storage), “Devolver o Carbono à sua Origem” para alunos do ensino secundário. Composta por 3 etapas: 1: inquérito diagnóstico sobre alterações climáticas e CCS; 2: palestra sobre o tema e o contributo do InCarbon; 3: inquérito de avaliação...
Strain partitioning in transpression; a major feature in the evolution of the I...
Dias, Rui; Araújo, Alexandre; Couto, Helena; Cruz, Cláudia; Ferreira, Joana; Gonçalves, Ana Marta; Lima, Alexandre; Lopes, Luís; Moreira, NoelAs the wavy pattern of fold belts is a common feature, since its recognition, the transpressive regimes were expected to be a pervasive mechanism on their evolution. Nevertheless, even in regions where oblique shortening is inferred, typical structures of transpression (e.g. transected cleavage and en echelon folds, shear or veins) are often absent. Instead, what is frequently observed is the juxtaposition of n...
Hydrogen storage in heterogeneous reservoirs: evaluating well configurations an...
Pereira, Pedro; Carneiro, Júlio; Canhoto, Paulo; Pedro, Jorge; Khudhur, Karwan; Mazezo, AugustoThe urgency in mitigating the climate change effects and the expecting rise of energy consumption in the coming decades will require zero-carbon sources like renewables, fossil fuels with carbon capture and storage, and sustainable storage solutions like underground gas storage. Hydrogen geological storage in porous rock formations is expected to play a major role for sustainable energy systems, offering large-...
Interactions and Impacts on the Efficiency of Underground Hydrogen Storage in S...
Pereira, Pedro; Carneiro, Júlio; Canhoto, Paulo; Pedro, Jorge; Khudhur, Karwan; Mazezo, AugustoThis study, part of the H2GeoStore R&D project, investigates underground hydrogen storage in saline aquifers as a solution for large-scale, long-term energy storage to support renewable energy systems. Using reservoir simulations of cyclic hydrogen injection and withdrawal under various conditions and reservoir heterogeneities, the research evaluates performance metrics like injectivity, productivity, and stora...
Hydrogen geological storage in saline aquifers based on seasonal and hourly cyc...
Pereira, Pedro; Canhoto, Paulo; Khudhur, Karwan; Carneiro, Júlio; Pedro, Jorge; Mazezo, AugustoUnderground hydrogen storage (UHS) in saline aquifers is a scalable solution to balance renewable energy intermittency. This study evaluates the techno-operational feasibility of UHS through dynamic numerical simulations using a 3D heterogeneous synthetic model representing real reservoir properties of a saline aquifer. Two operational cyclic profiles (seasonal and hourly) were developed based on real energy da...
Preliminary assessment of CO2 storage potential of deep saline aquifers in the ...
Pedro, Jorge; Moita, Patricia; Ribeiro, Carlos; Kilpatrick, Andrew; Edlmann, Katriona; Wilkinson, Mark; Afonso, Paula; Barradas, João; Carneiro, JúlioThe reduction of atmospheric CO2 through its safe geological storage, as CCUS techniques is one of the goals to achieve the 2050 commitment. Within the scope of thePILOTSTRATEGY project, two sedimentary sequences Triassic (on-shore) and Cretaceous (off shore) were object of a detailed study in order to evaluate their potential as CO2storage complexes in the Lusitanian basin (west Portuguese margin). A multi-dis...
