Integration of Ultra-High Temperature Thermal Energy Storage into Conventional Generation Sites

该项目的主要目标是促进低成本、长时间(超过4小时)的能源储存系统的知识，以促进将高渗透率的可再生能源发电纳入能源系统。使用超高温蓄热系统，这将增加传统发电站的灵活性，使其成为更清洁、可再生能源的可行后备，如风能、太阳能和潮汐。此外，该系统有可能完全由可再生能源充电，使用这些来源提供的能量将系统加热到所需的温度也是可能的。这项研究的大致目标是调查在超高温下的能量存储以及如何将这种热存储转化为可用能量。在该项目中，将实现以下三个目标：(1)研究直接从发电机组为储热设备充电的最合适的方法。(2)确定将uHTS系统集成到常规发电场所的技术要求，以及在恒定负载下匹配电厂所需功率输出波动的可行性。(3)考虑从储存的能量中生产氢燃料用于季节性储存的可行性。

The overarching aim of this project is to advance the knowledge of a low cost, long duration (beyond 4 hours) energy storage system to facilitate the integration of high penetrations of renewable generation into the energy system. Using the Ultra-High Temperature Thermal Storage system, this will allow for an increase in flexibility within conventional generation sites, permitting them to be a viable back-up for cleaner, renewable sources such as wind, solar and tidal. Furthermore, this system would have the potential to be charged solely from renewables, using energy supplied from these sources to heat the system to the required temperature would also be possible.The outlined objectives of this research are to investigate the storage of energy at ultra-high temperatures and how to convert this thermal store back to usable energy. In this project, the following three goals will be achieved:(1) Investigate the most suitable method for charging the thermal store directly from a generation unit.(2) Determine technical requirements to integrate a UHTS system into a conventional generation site and the feasibility of matching fluctuations in required power output for a plant with a constant load.(3) Consider the feasibility of producing hydrogen fuel from the stored energy for seasonal storage.
