英国发电厂的选址和技术趋势表明，除非广泛采用二氧化碳捕获和储存（CCS）技术，否则未来几十年对从河流中提取的冷却水的需求将会减少。如果英国要实现其二氧化碳和温室气体排放目标，CCS可能是必不可少的。因此，依赖于CCS的“脱碳”策略可能面临在河流流量低的时期没有足够的冷却水的风险。本文根据中等气候变化情景下低流量的区域淡水可得性，评估了区域对冷却水的淡水需求。在高CCS战略中，对水的需求大大超过了英格兰西北部、亨伯、东部中部和泰晤士地区目前和未来的可用性。这些风险可以通过增加混合冷却系统的渗透或将发电能力转移到河口或海岸来减轻。前者可能是……
Trends in the locations and technologies of UK electricity generation plant suggest that demand for cooling water abstractions from rivers will decrease in the coming decades, unless there is widespread uptake of carbon dioxide capture and storage (CCS). CCS may prove to be essential if the UK is to achieve its carbon dioxide and greenhouse gas emission targets. ‘Decarbonisation’ strategies that rely on CCS are therefore potentially at risk of not having sufficient cooling water in periods of low river flows. In this paper, regional freshwater demands for cooling water are assessed against regional freshwater availability at low flows in a scenario of medium climate change. In the strategy with high CCS, demands for water greatly exceed current and future availability in the north-west (NW) England, Humber, East (E) Midlands and Thames regions. These risks can be mitigated by increasing the penetration of hybrid cooling systems or shifting generating capacity to estuaries or the coast. The former could re...
