China, as the largest energy consumer, relies heavily on power generation from fossil fuels such as coal, leading to serious air pollution issues. It is therefore crucial for China to transit towards cleaner energy supply. Solar energy resources are abundant in China, particularly in the poorest western provinces, and renewable power generation can potentially play a vital role in energy supply for China in the future. On the other hand, although China became the second biggest economy in the world, it still remains a developing country and its per capita income is ranked as NO. 84 in the world. The exploitation of the abundant renewable energy resources in the underdeveloped regions in China can also help to boost local economy and tackle poverty. This project aims to develop a heat storage enhanced ORC power technology to utilise renewable heat sources (e.g. solar energy) for localised power and heat supply. ORC power generation technology is believed to be the most promising technology for power generation from low temperature heat sources. Unlike solar PV panels converting sun light into electricity, ORC power plants convert solar thermal energy to power. Integrated with heat storage, solar thermal ORC systems can overcome the intermittency of sun light and provide more stable power generation and heat supply. By increasing the running time of the ORC system, the payback also increases making this technology more affordable as compared to conventional, fossil based sources of energy. Furthermore, their reliability is also increased as the heat input and output are buffered and regulated. Apart from its application to solar energy, such technology is also attractive for utilising geothermal energy or waste heat sources. The wide installation of the developed system will make contribution to the decarbonisation of the economy China, and ultimately reduce the air pollution improve the urban populations' life quality. The proposed research and development will address several challenges that hinders the commercialisation of these technologies. On the Chinese side, Beijing University of Technology (BJUT) will develop high efficiency single screw expander technology for this project, and contribute to the development of high temperature heat storage technology using molten salts. The business partner, China Investment Yixing Red Sun Solar Energy Technology Company(CIYR), will manufacture the expanders and develop the solar powered technology demonstrator. On the UK side, Sunamp will develop and provide medium to high temperature heat storage technology using phase changer materials. The University of Glasgow (UOG) team, building upon their two on-going EPSRC projects on small scale ORC technologies, will focus on the design of the integrated system, the control strategy, and power electronic systems for the connection with grid. The four project partners, having expertise of different subsystems of this integrated technology, form a uniquely strong consortium to address these challenges and to bring the TRL of the proposed technology towards the commercialisation stage.

中国作为最大的能源消费国，严重依赖煤炭等化石燃料发电，导致严重的空气污染问题。因此，中国向清洁能源供应转型至关重要。中国太阳能资源丰富，特别是在最贫困的西部省份，可再生能源发电有可能在中国未来的能源供应中发挥至关重要的作用。另一方面，中国虽然成为世界第二大经济体，但仍然是一个发展中国家，人均收入排名NO。世界第84位。开发利用中国欠发达地区丰富的可再生能源也有助于促进当地经济发展、解决贫困问题。 该项目旨在开发一种储热增强型ORC发电技术，利用可再生热源（例如太阳能）进行局部供电和供热。 ORC发电技术被认为是最有前途的低温热源发电技术。与将太阳光转化为电能的太阳能光伏板不同，ORC 发电厂将太阳能热能转化为电能。光热ORC系统与储热相结合，可以克服太阳光的间歇性，提供更稳定的发电和供热。通过增加 ORC 系统的运行时间，投资回报也会增加，使得该技术与传统的化石能源相比更加经济实惠。此外，由于热量输入和输出得到缓冲和调节，它们的可靠性也得到了提高。除了应用于太阳能之外，这种技术在利用地热能或废热源方面也很有吸引力。该系统的广泛安装将为中国经济的脱碳做出贡献，并最终减少空气污染，提高城市人口的生活质量。拟议的研究和开发将解决阻碍这些技术商业化的几个挑战。中方方面，北京工业大学将为该项目开发高效单螺杆膨胀机技术，并为熔盐高温储热技术的发展做出贡献。业务合作伙伴中投宜兴红太阳太阳能科技有限公司（CIYR）将制造膨胀器并开发太阳能技术演示器。在英国方面，Sunamp将开发并提供使用相变材料的中高温储热技术。格拉斯哥大学 (UOG) 团队以两个正在进行的小型 ORC 技术 EPSRC 项目为基础，将重点研究集成系统、控制策略和与电网连接的电力电子系统的设计。四个项目合作伙伴拥有该集成技术不同子系统的专业知识，组成了一个独特而强大的联盟，以应对这些挑战并将拟议技术的 TRL 推向商业化阶段。
