Zero-Carbon Emission Integrated Cooling, Heating and Power (ICHP) Networks

在英国，建筑物和工业中80%的供暖使用天然气[1]。根据商业、能源和工业战略部的说法，向电力、氢能和生物能源的过渡有可能为低碳供暖做出重大贡献。关于氢气，一种潜在的方法是使用现有的天然气分配网来运输氢气。在这项研究中，我们探索了一个零碳排放的ICHP能源网络概念，通过生产，分配和利用氢气来实现脱碳加热和冷却。在全国范围内，现有的天然气电网基础设施将被改造，并用于将清洁能源生产的天然气和氢气输送到英国各地的分布式ICHP能源中心。在局部范围内，智能热网络将转化这些氢，并将其能量作为电力、供暖或制冷分配给城市地区的局部工业和住宅网络。此外，ICHP能源中心还将提供更多的灵活性和弹性等，并通过提供氢燃料和电动汽车快速充电提供整合运输能源服务的机会。该项目将重点研究ICHP概念在支持具有成本效益的热力行业脱碳和向低碳全能源系统过渡方面的作用和价值。该提案的目的是通过以下方式从整个系统的角度深入评估ICHP概念的作用：-在整个能源系统背景下量化基于ICHP的热力行业脱碳的技术经济价值，考虑短期，中期和长期不同碳排放目标的基础设施投资和运营成本。确定和量化灵活性选项的好处（即，能源储存、需求侧响应、氢基灵活天然气工厂）。评估ICHP范式在提高电力系统弹性方面的作用，考虑到在规划低碳能源系统时应考虑极端天气条件。输出将是整个系统利益相关者（政策，国家，地方和消费者）技术潜力的技术证据。

Across the UK, 80% of the heating in buildings and industries is generated using natural gas [1]. According to the Department for Business, Energy & Industry Strategy, transitioning to electricity, hydrogen and bioenergy have the potential to make a significant contribution toward low carbon heating. With respect to hydrogen, one potential approach is to use the existing natural gas distribution grid to transport hydrogen. In this research we explore a zero-carbon emission ICHP energy network concept for decarbonising heating and cooling through the production, distribution and utilisation of hydrogen. At the national scale, existing gas grid infrastructure would be modified and used to deliver natural gas and hydrogen produced from clean sources to distributed ICHP energy centres across the UK. At the local scale, intelligent thermal networks, would convert this hydrogen and distribute its energy as electricity, heating or cooling across urban areas in localised industry and residential networks. Furthermore, ICHP energy centres would also offer additional flexibility, resilience etc. and provide an opportunity to integrate transport energy services through the provision of hydrogen fuelling and electric vehicle fast charging. The project will be focus on investigating the role and value of the ICHP concept in supporting cost effective heat sector decarbonisation and transition to low carbon whole-energy system. The aim of the proposal will enable in depth assess of the role of ICHP concept from whole system perspective by:- Quantifying the techno-economic value of ICHP based heat sector decarbonisation in the whole-energy system context, considering infrastructure investment and operating costs for different carbon emissions targets in short, medium and long term.- Identifying and quantifying the benefits of flexibility options (i.e., energy storage, demand side response, hydrogen-based flexible gas plants).- Assessing the role of ICHP paradigm in enhancing the electricity system resiliency, given that the extreme weather conditions should be considered when planning low carbon energy system.Outputs will be technical evidence of the potential of the technology for stakeholders across the whole system (policy, national, local and consumers).
