描述了一种称为泵送热能存储（PTES）的大容量电力存储方案。PTES在充电阶段使用热泵来创建热和冷存储空间。在放电期间，使用热机耗尽这些热存储。这个版本的PTES使用填充床（或卵石床）作为能量存储。介绍了一种相对较新的设计特点，它涉及到分段的填充床。通过储层分段可以实现各种热力学益处，例如减少压力损失和增加每个循环存储的能量。该报告包括存储阶段的建模，并且发现分割可以减少发生的热平衡损失。一个简单的经济模型的PTES系统的介绍，使多目标优化的效率和资本成本可以进行。经济因素的敏感性进行了简要探讨。结果表明，冷填充床特别受益于分段。
A scheme for bulk electricity storage known as Pumped Thermal Energy Storage (PTES) is described. PTES uses a heat pump during the charging phase to create a hot and a cold storage space. During discharge, these thermal stores are depleted using a heat engine. This version of PTES uses packed beds (or pebble beds) as the energy store. A relatively new design feature which involves segmenting the packed beds is introduced. Various thermodynamic benefits can be achieved by reservoir segmentation, such as reduced pressure losses and increased energy stored per cycle. This report includes modelling of the storage phases, and it is found that segmentation can reduce the thermal equilibration losses that occur. A simple economic model of the PTES system is introduced so that multi-objective optimisation of efficiency and capital costs can be carried out. Sensitivity to the economic factors is briefly explored. The results show that cold packed beds in particular benefit from being segmented.
