本論文は、オーストリア・カプフェンベルクの地域暖房システムを2040年までに完全脱炭素化するための技術経済的最適化を提示。産業廃熱、再生可能熱、Power-to-Heat（P2H）の組み合わせを評価し、コスト最適なポートフォリオとP2H容量を特定。産業廃熱が支配的であり、グリッド連携P2Hは経済性と運用柔軟性を向上させるが、効果は閾値価格に依存する。自治体事業者への意思決定支援を目的とする。
English
This paper presents a techno-economic optimization for fully decarbonizing the district heating system of Kapfenberg, Austria by 2040. It evaluates combinations of industrial waste heat, renewable heat, and Power-to-Heat (P2H) to identify cost-optimal portfolios and P2H sizing. Industrial waste heat dominates; grid-enabled P2H improves economic performance and flexibility, but benefits depend on electricity price thresholds. The study provides decision support for municipal utilities.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも地域暖房の脱炭素化が進む中、本論文の最適化手法は自治体事業者にとって参考になる。特に産業廃熱と再生可能熱の統合やP2Hの導入検討に応用可能。ただし、欧州の電力市場条件が前提であり、日本への直接適用には調整が必要。
In the global GX context
This case study aligns with the EU Energy Efficiency Directive and heating decarbonization goals. It demonstrates a practical optimization workflow for integrating waste heat and renewables into district heating, relevant for global transition finance and infrastructure planning. The methodology can be adapted to other regions seeking cost-effective decarbonization of heat supply.

📄 Abstract（原文）
This paper presents a techno-economic optimisation of supply-side transition pathways for the district heating system of Stadtwärme Kapfenberg GmbH (Austria), aiming at full decarbonisation by 2040. Conducted within the SUPPORT DHC project, the study assesses how industrial waste heat, renewable heat options, and Power-to-Heat (P2H) can be combined to provide cost-efficient and reliable heat supply under evolving boundary conditions. A detailed energy system model was implemented in energyPRO and optimised at hourly resolution over a full year using validated demand profiles and operator-specific constraints, including source availability, maintenance schedules, technology priority constraints, operational cost parameters, and fixed installed capacities for existing assets. The analysis pursues two objectives: one with identifying cost-optimal supply portfolios for the current and planned expanded system, and the other with sizing P2H under two operational modalities (PV-only and PV plus grid electricity – grid import is permitted only when day-ahead prices are at or below a threshold; proxying hours with high renewable availability and/or low marginal emissions) within predefined capacity ranges. Across the analysed scenarios, industrial waste heat remains the dominant component of the cost-optimal portfolio. For the PV capacities considered, PV-only P2H exhibits a limited system-wide impact, indicating that achievable benefits depend strongly on local generation scale. In contrast, grid-enabled P2H improves economic performance and operational flexibility under the applied electricity price threshold formulation. Minimum levelized cost of heat occurs at approximately 2 MW P2H capacity with a grid price threshold of around 40 €/MWh; beyond this point, marginal benefits diminish as low-price operating hours saturate. The paper provides decision support for municipal utilities by demonstrating an optimisation-based heat production planning workflow that informs EED-aligned transformation and investment planning for accelerated integration of industrial waste heat and low-grade renewable heat, with sector-coupling options assessed to strengthen operational feasibility.
