本研究はフィンランドの地域暖房システムを対象に、気候変動による暖房需要減少が収益やエネルギー安全保障に与える影響をシミュレーション。小中大規模のシステムを2030年・2050年にわたりモデル化し、再生可能熱源への移行がもたらす課題を定量化。需要減少は収益損失を引き起こすが、バイオマス主体のシステムは排出コスト低減により安定した収益を維持可能と示した。
English
This study models small, medium, and large district heating systems in Finland for 2030 and 2050 under climate scenarios, finding that reduced heating demand leads to significant revenue losses for current systems. Systems transitioning to renewable sources like waste heat, electric boilers, and biomass maintain stable revenues due to lower emission costs. The results support strategic planning for sustainable and cost-effective district heating aligned with EU climate goals.

📄 Abstract（原文）
Climate change is expected to reduce heating demand in Finnish buildings, impacting district heating (DH) systems. This study models small, medium, and large DH systems for the years 2030 and 2050 using Representative Concentration Pathway (RCP) climate scenarios. The analysis uses energyPRO to simulate system operations based on fuel price prioritization, comparing future scenarios to a 2023 baseline. The transition from high-emission systems to sustainable energy sources—such as waste heat, electric boilers, and nuclear—poses challenges for revenue and energy security. While national-level studies exist, local-level insights are limited. Results show that reduced heat demand can lead to significant revenue losses in current systems, although renewable heat production increases. Smart future systems that minimize fossil fuel combustion and rely on biomass-based renewables maintain more stable revenues due to lower emission costs and consistent fuel pricing. These findings support strategic planning for sustainable, cost-effective DH systems aligned with national and EU climate goals.
