Projects and Major Achievements
This year we were successfully awarded 5 national-level projects, including 2 National Science and Technology Major Project of China, 3 National Science Foundation for Young Scholar.
In distributed energy system research direction, the world’s first 500 kW solar energy and fuel thermochemical complementary combined cooling, heating and power project is being carried out in Zhangjiakou. And the comprehensive utilization rate of the system is expected to reach more than 90%, and the total energy saving rate of the relative centralized energy supply system is expected to reach more than 30%; the first domestic hybrid skid-mounted system for cooling, dehumidification and marine aerosol removal driven by heat source was conducted on Yongxing Island in the South China Sea. The refrigeration power is 350 kW, the dehumidification power is 105 kW, the desalination rate is above 70%, and the air humidity after treatment is below 50%RH.
The technical acceptance of the advanced waste recovery heat pump prototype was completed. With a heat source of low-temperature flue gas (below 169.7 °C), the heat pump can produce saturated process steam at a pressure of 0.506 MPa. The heating output of the heat pump reached 72.75 kW, which verified the feasibility of the technical route of recovering low-temperature sensible heat to produce process steam. This technology is expected to be demonstrated in industrial production to provide technical support for energy saving and emission reduction in industrial processes.
In solar thermochemical and thermal power generation system integration research direction, 1) a 2 kWe spectral splitting prototype hybridizing PV and solar syngas power generation is successfully constructed and experimentally tested, which aims to achieve the effective utilization of full-spectrum energy. The testing results indicate the solar net electrical efficiency of the hybrid prototype is 5.2 percentage points higher than individual concentrated PV system. 2) A new method of water-based chemical looping cycle for hydrogen production driven by mid-temperature solar energy and natural gas is proposed. By this way, the solar energy is stored in the form of chemical energy, and which can also realize the integration of hydrogen production from natural gas and CO2 capture. Furthermore, an experimental platform for hydrogen production by mid-temperature natural gas chemical-looping reaction is developed.
Based on the analysis and prediction of solar energy development, the world's first universal solar simulation platform (70 kW) was built. The experimental platform could simulate solar energy point concentration and/or parallel sunlight, and the simulated solar flux spans 6 orders of magnitude. The platform is evaluated as “a promotion of frontier development in the field of solar power generation and solar fuel" by Professor Steinfeld, Academician of the Swiss Academy of Engineering Sciences.
Developed the world's first solar-driven fuel conversion prototype integrating parabolic trough collectors and 100 kW solar energy and clean fuel thermochemical hybrid power generation experimental platform. This research breaks through the limitations of high temperature solar thermochemistry, and leads a new direction of fuel chemical energy cascade utilization and solar energy thermochemical aided power generation to meet the national energy demands.
