本論文は、ポルトガル本土における深部地熱エネルギーの可能性を評価する。特に中央イベリア帯は、高放射能花崗岩と断層系による浸透性向上、好条件の水理地質により有望である。Hot Dry Rock/Enhanced Geothermal Systems（HDR/EGS）技術の実装がポルトガルのカーボンニュートラル移行に戦略的役割を果たす可能性がある。
English
This paper assesses the deep geothermal energy potential of mainland Portugal, focusing on Enhanced Geothermal Systems (EGS). The Central Iberian Zone is identified as most promising due to radiogenic granites and permeable fault systems. Implementation of HDR/EGS projects could strategically support Portugal's transition to a carbon-neutral energy system.

📄 Abstract（原文）
Geothermal energy has gained popularity for energy transition processes and electricity generation. The application of Enhanced Geothermal Systems (EGS) technologies increases the spatial reach of geothermal energy. A deeper comprehension of geological settings is crucial as it influences potential temperature, fluid composition and reservoir characteristics. Mainland Portugal’s Variscan and Alpine orogenies delineated the major faults and tectonic activity, as well as displaying magmatic activity with important granitic batholiths, producing high radiogenic heat. In addition, some areas of northern Portugal registered the highest annual rainfall and water recharge conditions, represented by 66 geothermal occurrences with natural hot water, reaching temperatures up to 76° C. The main goal of this research is to assess the state-of-the-art of the deep geothermal energy potential, in mainland Portugal, and successful implementation of Hot Dry Rock/Enhanced Geothermal Systems (HDR/EGS) projects for electricity production. Examining the methodologies applied in geothermal prospecting and exploration and proposing a geothermal assessment workflow will be very helpful on geothermal resources management. The geothermal systems in mainland Portugal are predominantly conduction-dominated geothermal systems. Among the different geological domains, the Central Iberian Zone stands out as the most promising for deep geothermal exploration due to its high-heat radiogenic granites, deep-rooted fault systems that enhance permeability, favourable hydrogeological recharge conditions and the spatial association of several thermal springs with major tectonic lineaments. Consequently, a transition from resource potential to practical implementation of geothermal energy could play a strategic role in Portugal’s transition to a carbon-neutral energy system.
