デンマークの点排出源からの将来のCO2利用可能量を推定。総量は年間約900万トンで、廃棄物焼却が30%を占める。化石由来CO2を考慮すると、一部をCCSに回し残りをCCUに利用することで気候中立が可能。廃棄物焼却施設への炭素回収導入は有効と示唆。
English
Estimates future CO2 availability from Danish point sources for Power-to-X, totaling ~9 million tons/year, with waste incineration contributing 30%. To achieve climate neutrality, a portion of the fossil CO2 must be sent to storage (CCS) while the rest is utilized (CCU). Concludes that carbon capture at waste incinerators is beneficial for supplying CO2 for synthetic fuels and chemicals.

📄 Abstract（原文）
Estimates were made of future annual amounts of CO2 available in Denmark from point sources potentially suitable for carbon capture. This involved industrial plants, biomass-based energy plants, waste incinerators and biogas plants. The total amount of CO2 potentially available in the future (around 9 million tons annually in Denmark) matches well the expected need for CO2 to produce renewable fuels for sea and air transportation and for production of chemicals for Denmark by Power-to-X. CO2 from waste incineration constitutes about 30% of the total amount of available CO2. Although the numbers are associated with significant uncertainty, the conclusion is that waste incineration may play an important role in supplying Power-to-X with CO2. The fossil part of the captured CO2 affects its environmental and economic aspects, but climate neutral CO2 from incinerators, even including climate neutral incinerators, can be obtained by routing part of the CO2 (around 30-40%) to storage (CCS) and utilizing the remaining part (CCU). The assessment suggests that from the perspective of climate change impacts, it makes sense to introduce carbon capture at waste incinerators as both underground storage and utilization seem relevant. The issue addressed is relevant to other countries, but numbers as well as the potential importance of waste management in supplying CO2 will vary.
