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

该项目的总体目标是推进低成本、长时间（超过4小时）储能系统的知识，以促进可再生能源发电的高渗透整合到能源系统中。使用超高温储热系统，这将增加传统发电站点的灵活性，使它们成为风能、太阳能和潮汐能等更清洁的可再生能源的可行后备。此外，该系统有可能完全由可再生能源充电，利用这些能源提供的能量将系统加热到所需的温度也是可能的。这项研究的主要目标是研究在超高温下的能量储存，以及如何将这种热量储存转换回可用的能量。在本项目中，将实现以下三个目标：(1)研究直接从发电机组向热储充电的最合适方法。(2)确定将UHTS系统集成到常规发电站点的技术要求以及恒负荷电厂所需输出功率波动匹配的可行性。(3)考虑利用储存的能量生产氢燃料进行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.
