Rebuilding a sustainable regional energy system for the greater Tokyo Metropolitan Region

提供了一项调查，旨在重建一个可持续的区域能源系统，该系统纳入了大东京都地区现有的DHC系统。通过定量分析，提出了可持续的未来替代方案，旨在减少二氧化碳排放和热岛效应，同时提高该地区的减灾能力。首先，收集了重建区域能源系统所需的基本信息，并将其组织成目标区域的数据库。要做到这一点，需要收集最新的可用数据，并将其组织到一个地理信息系统数据库中。收集了关于现有分布式能源中心系统和城市重建项目的现状的数据，以及在现有市区中提取具有区域能源系统高潜力的区域，并准备数据…。其次，根据重建区域能源系统的条件对地区进行了分类。基本上，分类包括“现有的市区没有DHC系统”、“有DHC系统的地区”、“新的市区重建区”和“沿海地区”。根据分类方案的结果，对使用DHC或建筑物内供热共享计划(连接相邻建筑物的供暖和制冷设备)、连接现有的DHC系统或使用京仙沿海地区未开发的能源资源实施地区规模能源使用的影响进行了量化评估。此外，还确定了在减灾方面迫切需要区域能源系统的几个优先领域。最后，提出了区域能源系统的未来愿景，旨在到2050年在东京中心地区创建低碳社会，并对几个剩余问题进行了思考，以使这一目标成为现实。简而言之，这一愿景探索了在深层地下供热网络中利用垃圾焚烧炉的余热和大型热电厂的热能的可能性，同时利用建筑物内热共享计划的好处来扩大东京的供热网络。对实现这一愿景所涉及的规划、相关实体和激励结构进行了解释。较少

An investigation is provided that looks into rebuilding a sustainable regional energy system that incorporates existing DHC systems for the greater Tokyo Metropolitan Region. Through quantitative analysis, sustainable future alternatives are proposed that are designed to reduce CO2 emissions and the heat island effect while improving the region's ability for disaster mitigation. Special attention is given to the 23 ward area of Tokyo and Keihin coastal areas, which exhibit higher concentrations of both energy consumption and untapped energy sources.First, basic information necessary to rebuild a regional energy system was collected and organized into a database for the target area. Doing so involved collecting the newest available data to be organized into a GIS database. Data was collected on the status of existing DHC systems and urban renewal projects ; as well as extracting areas in existing urban districts that exhibit high potential for a regional energy system, and preparing dat … More a on untapped energy sources, such as coastal industrial facilities.Next, areas were categorized according to conditions for rebuilding a regional energy system. Basically, categories include "Existing urban districts without a DHC system," "Areas with DHC systems," "New urban redevelopment areas," and "Coastal areas." Based on the results of the categorization scheme, quantifiable assessments were performed on the effects of implementing district-scale energy use using DHC or intra-building heat sharing schemes (connecting the heating and cooling equipment of adjacent buildings) ; linking existing DHC systems ; or using untapped energy sources in the Keihin coastal area. Furthermore, several priority areas were identified that are in high need of a regional energy system in terms of disaster mitigation.Lastly, a future vision of a regional energy system designed to create a low-carbon society in the central area of Tokyo by the year 2050 is proposed, with thought given to several issues remaining in order to make this a reality. In short, this vision explores the possibility of using waste heat from trash incinerators and heat from large scale cogeneration plants in a deep subterranean heat supply network, while leveraging the benefits intra-building heat sharing schemes to expand Tokyo's heat supply network. Explanations are provided of the planning, relevant entities and structure of incentives involved in making this vision a reality. Less
