フィンランドを事例に、ポイントソースCO2回収(PSC)と直接空気回収(DAC)の技術経済比較をシステムレベルで初めて実施。PSCは、DACのみに比べ年間システムコストを2.5%削減し、e-燃料コストを8-13%低減。北欧のエネルギー集約産業と厳しい気候条件における有効性を示す。
English
This study presents the first techno-economic system-level comparison of point source capture (PSC) and direct air capture (DAC) under Nordic conditions, using Finland as a case. Results show that a system utilizing PSC reduces annual system costs by 2.5% and the cost of e-fuels by 8-13% compared to a DAC-only system, offering efficiency and resource use benefits.

📄 Abstract（原文）
Many countries are working to reduce greenhouse gas emissions by phasing out fossil fuels and expanding low-carbon energy sources such as wind power and solar photovoltaics. Nordic countries face unique challenges due to harsh climatic conditions and high shares of energy-intensive industries in their total demand. While fossil fuel-related emissions can be eliminated, emissions from point sources, including biomass plants, pulp and paper mills, waste incinerators, and cement plants, will remain. These unavoidable emissions present an opportunity to convert CO 2 into valuable e-fuels and e-chemicals via power-to-X processes. This study presents the first techno-economic system-level comparison of point source capture (PSC) and direct air capture (DAC) under Nordic conditions, with multiple point source categories included in the assessment. The case of Finland is analysed using the LUT Energy System Transition Model, optimising system costs in five-year steps towards a renewable energy-based system by 2050. Two scenarios are compared: one combining PSC and DAC, and one relying entirely on DAC. Results indicate that with PSC, the system sources CO 2 almost exclusively from point sources, reducing annual system costs by 2.5% and average cost of e-Fischer-Trosch liquids and e-methanol by 8-13% compared to a DAC-only system. The optimal system enhances efficiency, land use, resource use, and provides environmental, economic, and societal benefits. The findings offer actionably insights for policymakers and industry stakeholders in Finland, the Nordics, and beyond, supporting cost-effective power-to-X pathways and accelerating the energy transition.
