Thermochemical energy storage systems: mathematical modelling and experimental evaluation of materials and prototype systems performance

将研究家用和热传输应用的热化学储能反应堆系统。首先，将对迄今为止TCES系统的材料、反应堆和应用领域进行详细的文献回顾。一个关键目标将是确定改进反应堆设计和复合材料开发的备选方案，这些方案有可能促进目前对这一低TRL研究领域的理解。还将确定通过部署这种系统可以实现的潜在经济和环境效益以及市场潜力。将从充放电速率和反应温度、反应速率的温度依赖关系、能量密度、成本、效率、腐蚀性和安全性等方面识别适合家庭和工业应用的材料，并对其进行表征。将进行一系列实验室分析技术，包括DSC、TGA和孔隙率分析，以表征候选材料和开发的复合材料。将使用COMSOL 6.0开发一个数学模型，以便能够预测TCES反应堆系统的性能。为了验证模型预测，将建造一个小规模的实验室反应堆系统，并对其进行仪表化和表征。在模型验证之后，将根据最初的实验结果和回顾的文献中的信息来设计、制造和表征更大规模的实验室反应堆。将模拟一系列设计的性能，以实现高效率、高能量密度、长期可重复循环稳定性和材料耐用性。在通过与这个更大规模的实验室系统的实验测量性能数据进行比较，确认所开发的模型预测的有效性后，该模型将用于开发和评估适合于家庭和热传输应用的规模的设计。根据不同应用的模拟性能，对成本、经济效益和环境效益进行了预测。

Thermochemical energy storage reactor systems for domestic and heat transport applications will be studied. Initially a detailed literature review in the area of materials, reactors, and applications of TCES systems to date will be performed. A key objective will be identifying options for improvement in reactor design and composite material development that have the potential to advance the current understanding of this low TRL research area. Potential economic and environmental benefits and market potential that could be realised by deploying such systems will also be identified. Materials suitable for domestic and industrial applications will be identified and characterised with respect to properties including charge/discharge rate and reaction temperature, temperature dependence of reaction rate, energy density, cost, efficiency, corrosiveness and safety. A range of lab analysis techniques including DSC, TGA and porosity analysis will be performed to characterise candidate materials and developed composites. COMSOL 6.0 will be used to develop a mathematical model to allow the performance of a TCES reactor system to be predicted. To validate the model predictions a small-scale lab reactor system will be constructed, instrumented and characterised. After model validation a larger lab scale reactor will be designed, fabricated and characterised based on initial experimental findings and information from the reviewed literature. Performance of a range of designs will be simulated with the aim of achieving high efficiency, high energy density, long term repeatable cycle stability and material durability. After confirming the validity of the developed model predictions by comparison to experimentally measured performance data for this larger lab scale system, the model will be used to develop and evaluate designs at a scale suitable for domestic and heat transport applications. Based on simulated performance for different applications predictions of cost, economic and environmental benefits will be made.
