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.

每年在英国，大约有48个TWH/年工业废物热源，相当于总体工业能源使用的六分之一。在这种工业废热中，从技术上讲，有可能通过特殊设计的能量转换技术来恢复11TWH/YR（2.2 mtco2/yr），例如加热和功率（CHP）。全球三分之一的能源消耗归因于工业部门，最终浪费了高达50％的能源部门。因此，用工业废料发电的市场是巨大的。该项目将为具有工业废料的能量转换系统创建创新的二氧化碳跨临界发电周期（IT-CO2）。将开发并安装在系统中，不使用不适用的二氧化碳液体液体泵，而是在系统中开发并安装了组合的二氧化碳压缩机和蒸气 - 液体排出器，以创建目标30％的热量到电气效率（即双重最新的ART效率）。项目成果将针对热密密集型行业，例如钢，玻璃和其他热密集型行星，这些行星需要在地点或网格连接上进行CHP解决方案。
