Each year in the UK, approximately there are 48 TWh/yr industrial waste heat sources which is equivalent to one sixth of overall industrial energy use. Of this amount of industrial waste heat, technically 11TWh/yr (2.2 MtCO2/yr) could be potentially recovered for useful purposes such as Combined Heat and Power (CHP) through specially designed energy conversion technologies. Globally one third of energy consumption is attributable to the industrial sector, with up to 50% ultimately wasted as heat. The market of power generation with industrial waste heat is thus enormous.The project will create an innovative CO2 transcritical power cycle (iT-CO2) for energy conversion systems with industrial waste heat. Instead of using an inapplicable CO2 liquid pump, a combined CO2 transcritical compressor and vapour-liquid ejector will be developed and installed in the system to create thermal-to-electrical efficiency of a target 30% (i.e. double state-of-the-art).The project outcomes will target heat-intensive industries such as steel, glass and other heat-intensive planets that require CHP solutions on sites or grid connections.

在英国，每年大约有48太瓦时/年的工业废热来源，相当于工业总能源使用量的六分之一。在这些工业废热中，技术上每年11TWh(2.2MtCO2/年)可以通过特别设计的能量转换技术被回收用于热电联产等有用的用途。在全球范围内，三分之一的能源消耗可归因于工业部门，其中高达50%最终被浪费为热量。因此，利用工业废热发电的市场是巨大的。该项目将为工业废热能源转换系统创造一种创新的二氧化碳跨临界动力循环(IT-CO2)。代替使用不适用的二氧化碳液体泵，将开发并在系统中安装二氧化碳跨临界压缩机和汽液喷射器，以创造目标30%的热电效率(即最先进的两倍)。项目成果将针对钢铁、玻璃和其他需要现场或电网连接的热电联产解决方案的热密集型行业。
