This paper presents a novel take on the energy-water nexus; exploring the coupling of renewable generation sources with drinking water distribution and wastewater collection assets that can store and release energy in response to temporal changes in residential heat demand. The paper presents the development of a simulation tool that uniquely integrates energy storage in drinking water reservoirs, heat recovery from sewers with wind turbine(s), solar photovoltaic panel(s) and a non-renewable source. Simulations at the scale of a 1000 household community and hourly intervals were used to find the optimal energy generation mix that minimises the total annual carbon emissions (embedded and operational). Three different locations in the UK were studied. Results show that the integrated idealised system is able to satisfy the heat demand for up to 63% of the time across a year with no carbon emissions, and reduce the annual associated CO2 by 60% when compared to all heat demand being satisfied by natural gas. This work shows that adopting such an interlinked system at a typical neighbourhood scale could help the UK meet its carbon emission obligations by substantially reducing the 18% of the UK's CO2 emission (currently estimated to be) related to domestic heat use.

通过在社区范围内整合城市供水系统和可再生能源来减少碳排放

本文提出了一种关于能量-水联系的新观点。探索可再生能源与饮用水分配和废水收集资产的耦合,这些资产可以存储和释放能量以响应住宅热需求的时间变化。本文介绍了一种仿真工具的开发,该工具独特地集成了饮用水蓄水池中的能量存储,具有风力涡轮机的下水道的热量回收,太阳能光伏板和不可再生能源。通过在1000个家庭社区的规模和每小时的时间间隔内进行模拟,来找到最佳的能源组合,以最大程度地减少年度总碳排放量(嵌入式和运营中)。研究了英国的三个不同地点。CØ2与天然气满足的所有热量需求相比,降低了60%。这项工作表明,在典型的邻里范围内采用这种相互联系的系统,可以通过大幅减少英国18%的碳排放量来帮助英国履行其碳排放义务。CØ2 与家庭供热有关的排放(目前估计为)。
