项目摘要

The UK is committed to become a low-carbon economy, with a reduction in greenhouse gas emissions to net zero by 2050. To do this will require fuel switching, for example from fossil fuel power to renewable energy sources. In the UK the main source of emissions from the residential and public sector in 2018 was the use of natural gas for heating. Due to the diversity of heat demand by consumers, which varies with time/season and in magnitude, no single approach will provide the optimum solution. Geothermal heat has been widely recognised to have the potential to make significant regional contributions to decarbonising heating in the UK, but currently deep geothermal and heat pumps account for just 5.2% of renewable energy sources. This project will investigate the use of closed loop single well geothermal systems as a viable alternative in scenarios where traditional open loop geothermal systems are not feasible. It particularly addresses the possibility of using wells drilled for other purposes, that might have failed in their original objectives, as sources of geothermal energy, thus mitigating some of the costs of their construction. Uniquely, the research will use, in Newcastle city centre, an existing 1.6km deep borehole and adjacent large instrumented building as a research facility, and integrate the research as part of whole energy system approach. Modelling will couple the heating/cooling needs of new urban buildings with an understanding of the performance of a single well geothermal system so that those demands are met. The project will address fundamental challenges in 1) heat abstraction and storage; 2) the engineering challenges of integrating geothermal energy to whole energy systems, and 3) regulatory and legal implications of closed loop systems and subsequent liabilities. The proposed research sets out to mitigate the technical and economic risks associated with deep UK geothermal energy for heating and cooling, and so to facilitate its future adoption to enable zero carbon targets to be reached.

英国致力于成为低碳经济，到2050年，温室气体排放量减少到零。为此，将需要燃油转换，例如，从化石燃料电力到可再生能源。在英国，2018年，住宅和公共部门的排放主要来源是使用天然气进行供暖。由于消费者的热量需求多样性，随时间/季节而变化，没有任何一种方法将提供最佳的解决方案。广泛认为地热热有可能在英国为脱碳加热做出重大贡献，但目前深地热和热泵仅占可再生能源的5.2％。该项目将在传统的开放环地热系统不可行的情况下调查使用封闭环单井地热系统作为可行的替代方案。它尤其解决了将钻探用于其他目的的井的可能性，这可能是其原始目标失败的，作为地热能的来源，从而减轻了其建设的某些成本。独特的研究将在纽卡斯尔市中心使用，这是现有的1.6公里深钻孔和邻近的大型仪器建筑物作为研究设施，并将研究整合为整个能源系统方法的一部分。建模将使新的城市建筑的加热/冷却需求与了解单个井地热系统的性能，以便满足这些需求。该项目将解决1）抽象和存储的基本挑战； 2）将地热能源与整个能源系统整合在一起的工程挑战，以及3）封闭环境系统以及随后的负债的监管和法律意义。拟议的研究旨在减轻与深英国地热能源进行供暖和冷却相关的技术和经济风险，从而促进其未来的采用，以实现零碳靶标。
