摘要

水与能源之间的相互依存关系(水-能源关系)已被确定为欧洲面临的主要挑战之一,路线图呼吁在这一领域制定综合方法。河流温度的升高是这一关系的核心,人为热污染加剧了全球变暖的影响。河水热泵可以发挥重要作用,在积极冷却水资源的同时,实现区域供热网络(DHN)的低碳化。因此,这篇短文的目的是根据目前的技术水平,确定需要应对的科学挑战和需要取得的进展。为了说明这一点,我们对法国里昂市的潜力进行了快速评估,结果显示可实现的降温幅度为 1.5 K,高于对水生生态系统产生影响的最低阈值,同时 DHN 可显著减少二氧化碳排放量(∼除以 10 倍)。由于该系统的整体性,对其影响的评估需要考虑能源、环境、经济和社会学等多方面的指标,并对其进行适当的定义和量化。在每个领域,都已确定了在现有技术基础上取得的进展,如 4E 分析、冷水羽流扩散、将生物多样性纳入生命周期评估等。

River water heat pumps to decarbonise district heating and promote the resilience of hydrosystems: Technico-economic, environmental and sociological challenges

The interdependence between water and energy (water-energy nexus) has been identified as one of the major challenges at European level, with roadmaps calling for the development of integrated approaches in this sector. The increase in river temperature is at the heart of this nexus, with anthropogenic thermal pollution adding to the effect of global warming. River Water Heat Pumps can play a major role by decarbonising district heating network (DHN) while actively cooling the aquatic resource. Hence, the objective of this short communication is to identify the scientific challenges to be met and the progress to be achieved considering the current state of the art. To illustrate the point, a rapid evaluation of the potential is performed for the city of Lyon in France resulting in an achievable cooling of 1.5 K which is above the minimum threshold to see an effect on aquatic ecosystem while the CO2 savings are significant for the DHN ( divided by a factor of 10). Because of its holistic nature, the impact assessment of such a system implies considering a wide diversity of indicators: energy, environmental, economics and sociological that need to be appropriately defined and quantified. In each field, progress beyond the state of the art to be performed has been identified, e.g. 4E analysis, cold water plume dispersion, integration of biodiversity in LCA.
