It is estimated that heat use (space heating, drying/separation, high/low temperature processing) accounts for over 70% of the total UK industrial energy use. There are significant opportunities for the improved use of low grade heat, particularly from plants which operate in a batching mode, i.e. when waste heat is generated at a different time from when there is a heat demand. The market potential for recoverable heat is estimated to be between 10TWh - 40TWh per annum. Recent developments in energy processing and the need for CO2 reduction have led to a growing interest in using this heat. To maximise the use of recoverable heat and support demand reduction there is a need for intelligent thermal/chemical storage which can be used when required, be upgraded for higher temperature applications or used to offset electricity and/or cooling demand within the plant. This ensures that heat energy which would otherwise be wasted is fully exploited.The project will bring together academic groups with expertise in thermodynamics, heat transfer and energy together with academics in business and our industrial partner, Spirax Sarco, a major UK based but global company who are major suppliers of industrial heating equipment. Our aim is to research and prove new flexible technologies that will be both wanted and used by process industries such as chemicals, paper and food processing. The systems studied will include:1. Simple storage with later delivery at nominally the same temperature. The use of advanced Phase Change Materials (PCMs) or Thermo-Chemical reactants will give much higher energy densities (i.e. be smaller) than stores using conventional materials. Size can be a critical factor in industrial applications, but attention must also be paid to cost, corrosion issues, health and safety etc.2. Thermal transformers that can return a fraction of the stored heat at a higher temperature than it went in. This allows some of the waste heat that would otherwise be wasted to be upgraded to steam raising temperatures for re-use. Steam is still the preferred heating medium in many process industries and possible applications are numerous.3. Variations on Thermo-Chemical storage devices can also deliver a work (electrical) output or refrigeration rather than heat as can PCM stores in conjunction with Organic Rankine Cycles. We intent to prove, compare and contrast the economics and practicability of these options.In addition to proving the technical potential of these systems it will be essential to look at their control strategies and how they can be integrated with real products. This demands a new theoretical approach. When recovering / transferring heat between continuously operating streams the technique of pinch-point analysis is used to maximise the possible quantity of energy recovered. This is much complicated when heat inputs and outputs can be at different times. We will develop a 'temporal pinch-point analysis' to cope with the increased complexity presented.The technologies will have sufficient flexibility to be applied to different size systems and this flexibility will benefit a wide range of potential energy consumers.

据估计，热能消耗（空间加热、干燥/分离、高/低温处理）占英国工业能源消耗总量的70%以上。改善低品位热能的利用存在重大机会，特别是对于以批量模式运行的工厂，即当废热在与热需求不同的时间产生时。可回收热量的市场潜力估计每年在 10TWh - 40TWh 之间。能源加工的最新发展和减少二氧化碳排放的需求导致人们对利用这种热量越来越感兴趣。为了最大限度地利用可回收热量并支持减少需求，需要智能热/化学存储，可以在需要时使用，升级以适应更高温度的应用或用于抵消工厂内的电力和/或冷却需求。这确保了本来会被浪费的热能得到充分利用。该项目将汇集具有热力学、传热和能源专业知识的学术团体以及商界学者和我们的工业合作伙伴斯派莎克（Spirax Sarco），这是一家总部位于英国的跨国公司他们是工业加热设备的主要供应商。我们的目标是研究和证明化学品、造纸和食品加工等加工行业需要和使用的新型灵活技术。研究的系统将包括：1．简单储存，稍后在名义上相同的温度下交付。与使用传统材料的存储相比，使用先进的相变材料（PCM）或热化学反应物将提供更高的能量密度（即更小）。尺寸可能是工业应用中的关键因素，但还必须注意成本、腐蚀问题、健康和安全等2。热变压器可以以比进入时更高的温度返回一小部分储存的热量。这使得一些本来会被浪费的废热升级为蒸汽，提高温度以供再利用。蒸汽仍然是许多过程工业中首选的加热介质，并且可能的应用很多。3．热化学存储设备的变体还可以提供功（电）输出或制冷而不是热量，就像 PCM 与有机朗肯循环结合存储一样。我们的目的是证明、比较和对比这些选项的经济性和实用性。除了证明这些系统的技术潜力之外，还必须研究它们的控制策略以及它们如何与实际产品集成。这需要一种新的理论方法。当在连续运行的流之间回收/传递热量时，使用夹点分析技术来最大化可能回收的能量。当热量输入和输出可能在不同时间时，这就变得非常复杂。我们将开发一种“时间夹点分析”来应对日益增加的复杂性。这些技术将具有足够的灵活性，可以应用于不同规模的系统，这种灵活性将使广泛的潜在能源消费者受益。
