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...
Mineralogical and chemical changes induced by experiments of interaction betwee...
Moita, Patricia; Berrezueta, Edgar; Abdoulghafour, Halidi; Beltrame, Massimo; Mirão, José; Ribeiro, Carlos; Barrulas, Pedro; Pedro, JorgeThe focus of this research is a qualitative study of mineralogical and chemical changes in plutonic mafic rock samples after exposure to a CO2-rich brine, under supercritical conditions (SC), to clarify the behavior of brine and rock in the initial stages of mineral carbonation. The studied rock consists of a gabbro-anorthosite from the Odivelas massif, in southern Portugal. The sample was exposed to a SC CO2-r...
Basic plutonic rocks: an unconventional solution for CO2 storage through minera...
Carneiro, Júlio; Moita, Patrícia; Pedro, Jorge; Berrezueta, Edgar; Abdoulghafour, Halidi; Marques, Fábio; Araújo, Alexandre; Beltrame, MassimoCO2 capture and geological storage (CCS) is recognized as an essential technolo-gy to achieve carbon neutrality and the Paris Agreement targets. The success of in-situ mineral carbonation of CO2 in basalts accomplished in the Carbfix project, opened up the prospect for considering other igneous rocks as viable targets for CO2 storage. The InCarbon project embraced the challenge to test the potential for mineral...
Hydrogen geological storage and interactions in porous media of subsurface geology
Pereira, Pedro; Carneiro, Júlio; Canhoto, Paulo; Pedro, Jorge; Abdoulghafour, HalidiThe national and European hydrogen strategies rely on producing vast amounts of green hydrogen, part of which will have to be stored in geological formations. While storage in salt cavities is a mature technology, the porous media is prone with challenges. Funded by FCT, H2GeoStore project will address impacts on hydrogen storage efficiency and seal integrity in saline aquifer reservoirs. H2GeoStore outcomes ai...
