  • The marine energy potential maps for mainland Portugal consists of the mapping the main wind and wave parameters for the offshore environment at the height of 100m (offshore wind resource) and at surface (wave energy resource). The offshore wind resource is performed with a sophisticated mesoscale atmospheric model, capable of describing the main wind phenomenology near the Portuguese coast, and contains the mapping of the average wind speed [m/s], Wind Power Flux [W/m2] and the map of the annual number of hours at full capacity NEPS of a standard reference turbine as well as the NEPS maps [h/year] for specific type of bottom-fixed wind turbine systems - "Jacket" and "Monopile" or Floating – WindFloat. The offshore wind resource maps represent the climatology of the wind resource as well as characteristics of the wind phenomenology associated to the land-sea interaction along the Portuguese coast. Regarding the wave energy maps, the estimation of the wave energy resource is based in estimating the main sea-wave characteristics and the wave energy production for standard different wave system types – oscillation water column converter; floating two-body heaving converter bottom-fixed oscillating flap converter. The maps of the wave energy resource are a merging of observational data (boys) and information from the ONDATLAS database as well as data from numerical modeling with the MAR3G model all with 10 years of data . This way the wave energy resource maps describe the main characteristics of the average wave resource for a period of 10 years, which is representative of the sea state climatology of Portugal. All wave energy maps are expressed in [kW/m]. Also, all wind and wave energy resource maps are processed with a high spatial resolution of 1km x 1km from the coast up to the bathymetric of 300m. Some wind and wave energy maps are freely available to download in a course but larger grid area (5Km x 5Km). In time, the offshore wind maps will include higher heights.

  • The Critical Raw Materials Deposits Map in Mainland Portugal is a compilation of the known mineral occurrences and deposits of the most critical raw materials according to the latest list published by the European Commission in 2023.

  • The Geological Map of Portugal at a scale of 1:1 000 000, published by LNEG in 2010, constitutes the synthesis document of the current knowledge about the geology of mainland Portugal and all insular territory: the Azores and Madeira Archipelagos. This map includes for the first time the geology of the continental shelf around mainland Portugal, drawing on over 30 years of marine geological research. The map comprises: a Geological Map of Mainland Portugal, a Geological Map of the Continental Shelf, and separate geological maps for the Azores and Madeira archipelagos (all at a scale of 1:1 000 000). Additionally, it includes a Neotectonic Scheme of Mainland Portugal with Hypsometry at a scale of 1:4 000 000, a Tectono-Stratigraphic Scheme at 1:5 000 000, and a Location Map at 1:20 000 000.

  • 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.

  • Database that stores and catalogues thin sections and polished surfaces, as well as the corresponding source samples, providing a valuable resource for the scientific community.

  • This product was developed by LNEG with a view to the future identification of “Renewable Acceleration Areas” for the deployment of renewable electricity production plants in Mainland Portugal. The work took place within the scope of an informal Working Group, coordinated by LNEG and involving: the Portuguese Environment Agency (APA), the General Directorate of Energy and Geology (DGEG), the General Directorate of Territory (DGT), the Institute of Conservation of Nature and Forests (ICNF) and the General Directorate of Cultural Heritage (DGPC). The map identifies the areas in m2 of mainland Portugal with the least sensitivity (environmental, cultural heritage and other) which as such may be considered in the definition of future renewable "Acceleration Areas" within the framework of the revised RED Directive (Renewable Energy Directive. As these areas are not covered by exclusion conditions regarding the preservation of environmental and heritage values (among other), a simplified permitting process for renewable power production plants (solar photovoltaic and wind) could be established, thus allowing to accelerate its implementation without compromising other environmental and territorial values. The mapped areas are preferred areas from the point of view of simplifying the permitting process, but they are not exclusive. In other words, renewable power plants can be implemented in other locations following the normal permitting process. It should be noted that the presented results reflect the situation as of June 2023, and much of the information used is dynamic in nature, meaning this product must be periodically updated. This document is complemented with several electronic Geographic Information System (GIS) files containing the supporting data produced/compiled and collected. Last but not least, this first mapping focuses exclusively on non-artificialized areas. Although the implementation of renewables in a distributed manner in a built/artificialized environment is essential for the country, the analysis of this scope is carried out in another work.
