本論文は、2050年のネットゼロ・スイス電力系統における深部閉ループ先進地熱システム（AGS）の統合を分析する。投資コストの不確実性を考慮し、コスト最小化の観点からAGSの経済的競争力を評価。結果、補助金がある場合21,500ユーロ/kWe以下、ない場合15,000ユーロ/kWe以下の設備投資で競争力を持つ。AGS導入によりガス火力や蓄電池の必要性が減り、系統信頼性も向上する。

This paper analyzes the integration of deep closed-loop Advanced Geothermal Systems (AGS) in the 2050 net-zero Swiss power system. It finds that AGS become economically competitive at overnight costs below 21,500 EUR/kWe with subsidies and below 15,000 EUR/kWe without. AGS deployment reduces the need for gas plants, batteries, PV, and wind, and can enhance system reliability due to their distributed and flexible nature.

📄 Abstract（原文）
Deep closed-loop Advanced Geothermal Systems (AGS) are a carbon-free electricity generation technology that can support the transition to net-zero power systems by 2050. Unlike conventional geothermal power plants, AGS do not require permeable geologic formations and are thus largely geology-independent, providing distributed, flexible, and dispatchable electricity. Although their resource potential and technological characterization are widely researched, investment costs remain uncertain, and their integration into national power systems has hardly been studied. This paper analyzes the integration of AGS in the 2050 net-zero Swiss power system, focusing on their techno-economic aspects and their contribution to power system security. The generation potential of AGS is computed and aggregated at each transmission grid node, and the conditions under which AGS become an economically competitive generation technology from a cost-minimization perspective are investigated. The interactions of AGS with other generation and storage technologies, as well as with overall system operations, are assessed. Finally, the grid nodes at which AGS are optimally deployed are identified, and AGS’ impact on power system reliability is investigated. The results suggest that AGS become economically competitive in Switzerland at overnight investment costs below 21,500 EUR/kW e when renewable generation subsidies are in place, and below 15,000 EUR/kW e when they are not. The deployment of AGS reduces the need for gas-fired power plants, battery storage, PV, and wind, and AGS installations can concentrate in areas of high demand, high demand-to-generation ratio, or frequent network congestions. Owing to their distributed and flexible nature, AGS also have the potential to enhance system reliability. ; ISSN:0306-2619 ; ISSN:1872-9118
