The 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...
O 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...
The 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-...
This 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...
This study, conducted within the PilotSTRATEGY project, explores the optimization of CO₂ injection under geological uncertainties in the Q4-TV1 prospect of the offshore Lusitanian Basin, Portugal. A static model integrating seismic and well data was coupled with dynamic simulations in the Big Loop framework, combining Bayesian optimization with uncertainty analysis. Geological risks, including intersecting faul...
Underground 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...
The 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...

The Portuguese target for carbon neutrality by 2050 will require the deployment of CO2 capture, utilization and storage (CCUS). Although Techno-Economic Assessments (TEA) of CCUS scenarios targeting specific industrial sectors have been performed in Portugal in the scope of previous EU projects, the detailed analysis for the early stages of a CCUS chain, focusing on pilot scale, is necessary for policy makers a...
