The CONVERT project aimed at identifying, in an objective and quantitative way, the different types of endogenous biomass that can be applied in the short-medium term to economically viable technological solutions for the production of power and heat, energy vectors, and especially advanced biofuels. These should comply with all the sustainability criteria set by the European Directives, in particular the Red II (2015/1513) Directive. This project included the following activities: Activity 1 - Energy potential of the organic fraction of solid urban waste; Activity 2 - Energy potential of biowaste produced under industrial context; Activity 3 - Potential of mainland Portugal for energy crops; Activity 4 - Conversion technologies and respective energy products; Activity 5 - Life Cycle Analysis and estimation of Sustainable Value and Activity 6 - Communication plan. As part of Activity 3, LNEG developed a spatial data infrastructure to facilitate the exchange and use of information between all the beneficiary agents in a first phase, with visualization and consultation via the web. These data are crucial for choosing locations for energy crops/microalgae and for selecting the species to cultivate, while also identifying critical or limiting locations for their utilisation.

Geological Map of the Algarve Region, scale 1:100 000, produced by the Geological Survey of Portugal in 1992, as part of systematic geological surveys of the Meso-Cenozoic coast of the Algarve.

Prototype of a seamless data model of the Digital Geological Map of Portugal, at scale 1:200 000, in which the mapped units of mainland Portugal were inventoried and organized according to a unified legend (LU). Standardization and harmonization work was carried out between contiguous maps, as well as updating the units through extensive bibliographic research and, above all, leveraging on the experience and knowledge existing at LNEG. The following elements are available: LU code, unit code, unit name, and associated lithological description. This work is under development and reflects the situation as of September 2025.

This work was carried out by the GTAER - Working Group for the Definition of Renewable Energy Acceleration Areas, created by Order no. 11912/2023 of 23 November, and is intended to consolidate and strengthen the previous work carried out to identify the areas with the least sensitivity for the location of renewable electricity production units (solar photovoltaic and wind). The work presented here assessed the potential for implementing these units in natural areas or territories. The process of identifying PRAAs, took into account 5 different scenarios, depending on whether or not the following constraints were excluded: (i) areas relating to aquifers classified as porous or essentially porous, belonging to the western edge and the Tejo-Sado basin; (ii) areas relating to the distance between residential and mixed-use built-up areas and (iii) available RAN (National Agricultural Reserve) and REN (National Ecological Reserve) areas. The areas presented contribute to the definition of future preferential RAAs areas - they do not constitute the formal definition of the RAAs. In future RAAs, the licensing process will be simplified. It should be noted that these areas are not exclusive, and renewable energy units can be implemented in the rest of the territory in accordance with the normal licensing process. The results presented reflect the situation as of February/March 2024.
