Enhanced electricity generation through waste heat utilisation and thermodynamics of supercritical CO2

PJH Partnership已经确定了一种创新工艺，该工艺既可以循环二氧化碳，又可以使用高效的工作流体将废热有效地转化为电力。该系统操纵CO2的多个相变，以最大限度地提高流体的热力学势，该流体既高度稳定，又容易获得和惰性。由于其在超临界状态下的高密度，由这种流体驱动的发电技术需要更小的占地面积，小十分之一的涡轮机尺寸和显著降低的运营成本。其好处包括化石燃料发电量的增加，目前平均为45%，最高可达60%。潜在的CO2减排总量为每年142.3mT，通过更好地利用国家能源资产来提高安全性。这个为期12个月的项目旨在评估使用工艺方法产生超临界CO2的技术可行性，并评估其在使用涡轮机技术发电中的效率。模块化改造系统的目标是化石燃料发电机和可再生能源运营商，预计将于2018年进行商业部署。

PJH Partnership has identified an innovative process that can both cycle CO2 and efficiently convert waste heatto power using a highly efficient working fluid. The system manipulates multiple phase changes of CO2 tomaximise the thermodynamic potential of a fluid that is both highly stable, readily available and inert. Due toits high density in the supercritical phase, power generation technology powered by this fluid requires anotably smaller footprint, a tenth less turbine size and significantly less operational costs. Benefits includeenhanced electricity generated from fossil fuel sources currently averaging 45%, up to 60%. Potential CO2avoidance totals 142.3mT per year, with increased security through better utilisation of national energy assets.This 12-month project aims to assess the technical feasibility of generating supercritical CO2 using the processmethodology and evaluate its efficacy in power generation using turbine technology. The modular retrofitsystem targets fossil fuel generators and renewable operators with future commercial deployment anticipatedend-2018.
