'Nuclear energy diversified application' has become an important consensus reached by the industry at the 2017 Nuclear Industry Chain Summit held in Yantai on the 9th. Zheng Jianchao, a member of the Chinese Academy of Engineering, said that in the future, the major development directions for the application of nuclear energy will still be large-scale nuclear power development, but nuclear energy will enter The pace of transportation needs to be accelerated, among which the scale-up of hydrogen production from HTGR, the integration of high-energy-density safety hydrogen storage technology and hydrogen conversion technology, and the development of a green electric vehicle with a complete industrial chain are the most attractive directions.
Zheng Jianchao pointed out that at present, the utilization of nuclear energy in transportation systems is still very limited. However, the existing pure electric vehicles are not completely clean and low-carbon in terms of their entire life cycle. Due to limited storage density of batteries, mileage is limited. Proposed an important technical route for the scale of nuclear energy to be applied to land transport, namely, to promote the integration of large scale hydrogen production technology, high-energy-density hydrogen storage technology and hydrogen-electricity conversion technology in high-temperature gas-cooled reactors and the development of 'clean and low carbon' New green electric car.
Zheng Jian Chao stressed that the high-temperature gas-cooled reactor is a very safe reactor, its most attractive application prospect is the scale of hydrogen production. To develop pyrolytic water-to-hydrogen ultra-high temperature gas-cooled reactor, but also faces some technical bottlenecks, such as Helium sealing difficulties need to strengthen the basic research of technology, materials, technology.Fuel cell based hydrogen conversion system is a mature technology proven through long-term engineering, the scale of application of the obstacles is the existing catalyst expensive, economical Room for improvement.
In recent years, significant progress has been made in dissolving hydrogen storage technologies of organic solvents, such as heterocycles, and the high density of hydrogen at normal temperature and pressure has been achieved Storage, storage of hydrogen energy density up to 20 times the pressure of hydrogen storage.Use ordinary car fuel tank hydrogen storage, electric car mileage up to 600-900 km, and safety is higher than the traditional car fuel.According to experts, all-green electric car The scale of application has seen the dawn.Zheng Jianchao urged the country as soon as possible related research and development included in the important agenda.
