HOLBORN STATION CAPACITY UPGRADE - TRIGENERATION FEASIBILITY STUDY

伦敦地铁的任务是提高其主要基础设施项目的可持续性，包括建设、运营和维护。伦敦人口和就业的持续增长以及与之相关的乘客需求的增加需要继续进行主要的车站能力升级项目。霍尔伯恩车站是伦敦大学最优先的车站能力升级项目，将于本世纪20年代中期交付。该项目还将促进车站站台冷却和更换、扩大地下室水平牵引的子站，以支持计划中的中线升级，在未来10-15年内增加列车频率。这两个项目元素结合在一起将提供废热，否则这些废热将被耗尽到这里，给伦敦带来不可持续的结果。因此，热电联产可行性研究的目的是测试这些余热能否被利用来供应当地第三方，并测试是否有更全面、更分散的方式来产生冷却和电力，作为发电站能力项目的一部分。

London Underground is tasked with increasing the sustainability of its’ major infrasructure projects, includingboth the construction, operation and maintenance. Continued London population and employment growthand associated increase in passenger demand necessitates continued major station capacity upgrade projects.Holborn station is LU’s highest priority station capacity upgrade project and will be delivered by the mid 2020s.The project will also facilitate station platform cooling and a replacement, expanded basement level tractionsub-station to support the planned Central line upgrade increased train frequency over the next 10-15 years.Combined these two project elements will provide waste heat that would otherwise be exhausted toatmsophere, creating an unsustainable outcome for London. The Trigeneration feasibility study therefore aimsto test whether this waste heat could be harnessed to supply local third parties and to test whether there is amore holistic, decentralised means of generating cooling and power as part of the station capacity project.y
