The lab has completed and received acceptance of 1 frontier science key research project of the CAS.
In the research direction of distributed energy system, the laboratory proposed a solar-coal thermochemical hybrid utilization method and a power generation system, using concentrated solar energy to provide reaction heat for the reaction process. Unstable and intermittent solar energy was converted into syngas chemical energy with high energy level, and then the net power generation efficiency and exergy efficiency of the proposed system reached 53.06% and 52.24%, respectively.
The laboratory proposed a novel combined variable valve timing and throttle opening method to improve full-condition system performance. Regarding the high-temperature heat pump and phase-change storage technology, a working fluid pair and phase-change energy storage experiment bench have been built.
The laboratory prepared a demonstration plan for MW-level distributed energy system and promoted the implementation of cooling, heating, and power projects in industrial/entrepreneurial parks in south China. The laboratory completed the research report on Xinjiang oilfield dual carbon strategy and the application feasibility analysis of distributed energy system and multiple renewable energies.
The two national key R&D plan smart grid special projects led by the laboratory were successfully completed and passed the project performance evaluation organized by the Ministry of Industry and Information Technology.
In the research direction of solar thermochemical and thermal power generation system integration, the laboratory originally proposed a solar thermochemical three-step water-splitting cycle for hydrogen production, greatly reduced the temperature of hydrogen production by pyrolysis of water, and developed the principle prototype. An integrated method for hydrogen production and decarburization by water-based chemical looping of natural gas was innovatively proposed, where the laboratory made breakthrough in the whole chain of carbon-hydrogen directional migration theory, oxygen carrier material, reactor, and hydrogen production system. A 1 Nm3 /h prototype of principle was developed, where key technologies are being developed and industrialized. By tackling key technologies of multi-energy source complementing, the first demonstration of a MW scale solar and fuel thermochemical complementing distributed energy system has been built.
The laboratory proposed for the first time a new principle and method of multiproduct sequential separation-driven mid-temperature solar steam methane reforming. High-purity H2 and CO2 are directly obtained with the nearly complete conversion of methane under mild conditions of 400°C and 0.1 MPa, enabling a remarkable decrease in the SMR temperature and a dramatic reduction in energy penalties of separation. The efficiency of solar-to-H2 can be enhanced to 46.5% or above, which were published in the international academic journal Energy & Environmental Science.
The laboratory studied the photo/thermal coupled utilization concentration solar energy and gas-solid phase photo chemical reaction. A novel photo/ thermal coupled solar chemical looping method was proposed for hydrogen production; in addition, a testing experimental apparatus was built and experimental validation was complemented.
In the research direction of low-energy-consumption CO2 capture at the origin of fuel conversion, the laboratory proposed a novel coupling technology of pyrolysis/gasification with decarbonization; a 10 kg coal pyrolysis unit and 3 tons /day scaled integrated pilot plant for external combustion coal pyrolysis were designed. Besides, a 30 kW coke-CO2 gasification experimental device was constructed, and the pilot run was completed. At present, the application of coal classification technology is being actively promoted in flexible peak shaving of coal-fired power plants and coal-to-hydrogen industry.
