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...
Carbon capture from industrial, high concentration CO2 sources, combined with CO2 transport, utilization and storage (CCUS) is a way to reduce greenhouse gas emissions. CCUS will play an important role in our transition into, and, also beyond the green shift, as CCUS both significantly reduces emissions from industrial processes and offsets emissions from hard-to-remove sectors – leading to the global net-zero ...

Among the various sources of energy considered as renewable, biomass remains the only resource that contributes significantly to the world energy supply. However, fossil fuels, such as coal, oil and natural gas, still dominate the demand and energy supply. In EU28 countries, the share of biomass in total primary energy production in 2016 was 17.8% (without non-renewable and renewable industrial wastes), coming ...
Forest biomass has been having an increasing importance in the world economy and in the evaluation of the forests development and monitoring. The main goal of this study is the development of functions for the estimation of aboveground biomass, using crown cover as independent variable, for Quercus rotundifolia, Quercus suber and Pinus pinea in agroforestry systems, both for monospecies and multispecies stands,...
The estimation of vegetation parameters, such as above-ground biomass, with high accuracy using remote sensing data, represents a promising approach. The present study develops models to estimate and map above-ground biomass of Mediterranean Quercus rotundifolia stands using one QuickBird satellite image in pan-sharpened mode, with four multispectral bands (blue, green, red and near infrared) and a spatial reso...
The present work evaluates the quantity and spatial distribution of potential forest residues in Alentejo, the largest geographic region in Portugal. Forest residues from the five main species in Portugal, tasmanian blue gum, cork oak, maritime pine, holm oak and stone pine, were assessed. The characterization of the biomass residues was performed in a Geographical Information System environment using the Portu...
Cork oak ecosystems play a very important environmental and socio-economic role in the Mediterranean basin. Their maintenance relies highly on the cork industry, which in turn, is dependent on these ecosystems. Despite the positive impacts of the cork industry, this is an energy-intensive sector, with a strong need for process heat. Therefore, a careful management of heat consumption is important to minimize it...
Biomass estimation is a tool for evaluating stands and forest dynamics. Traditional indirect methods use forest inventories and allometric functions at tree level to evaluate biomass at plot level, and an extrapolation method to assess an area. The goal of this study was the development of allometric functions for Pinus pinaster with crown horizontal projection derived from very high spatial resolution satellit...
As atuais projeções indicam que são necessários esforços adicionais para atingir os objetivos de mitigação acordados para 2030 bem como a ambição de reduzir as emissões de gases com efeito de estufa da UE em 80 a 95% em 2050, face a 1990, sendo este o objetivo necessário a longo prazo para descarbonizar o sistema energético e industrial Europeu consentâneo com uma trajetória de estabilização climática do Planet...
