Recently, the list of winners of the 2021 Zhejiang Provincial Science and Technology Award was announced. 48 scientific and technological achievements led or participated in by enterprises and institutions in Ningbo have won awards, including 3 Provincial Natural Science Awards, 3 Provincial Technology Invention Awards, and 42 Provincial Science and Technology Progress Awards. The total number of awards has maintained a high level in recent years.
From the perspective of the value of achievements and the level of technological innovation, some award-winning achievements in Ningbo have made breakthroughs in basic research and source innovation. For example, the project of “Key Technology and Application of Ultra High Power Supercapacitor” led by Ningbo University won the first prize of technological invention. This project aims at the key common technical problems that need to be solved urgently in order to improve the power density of supercapacitors, such as the significant reduction of electronic impedance and ionic impedance. It pioneered the large-scale preparation technology of new carbon Aerogel materials with high conductivity and high bulk density, and realized the upgrading of electrode materials. In addition, in response to the problem of high power conversion efficiency in supercapacitor systems, we have pioneered the active balancing energy management system for high-power supercapacitors, which improves the efficiency of energy power transfer. The reporter learned from the installation of key equipment for efficient purification of ship exhaust that the ultra-high power supercapacitor developed based on this project has a power density of 75kW per kilogram and an energy density of 10 per kilogram.1Wh, overall at the international leading level of similar products. The products are mainly used in special field power systems, rail transit vehicle power systems, port and oilfield machinery potential energy feedback power systems, new energy vehicle braking energy feedback systems, etc. In the past three years, the direct economic benefits have exceeded 2 billion yuan.
Ningbo is home to the “largest port” with frequent ship traffic. How to promote the leapfrog development of ship exhaust purification technology? The project of “Key Technologies and Applications for Efficient Purification of Ship Exhaust”, which was completed with the participation of Ningbo Zhongce Power Electromechanical Group, a Ningbo enterprise, and Ningbo University, has developed key technologies and equipment such as catalytic denitration, washing and desulfurization of ship exhaust through new methods such as machine learning assisted catalyst formula screening, and has created a collaborative efficient purification technology system for ship exhaust, The emission indicators are significantly better than the requirements of the International Maritime Organization (IMO) regulations. The relevant research and development technology has been certified by the seven major classification societies worldwide and has been applied on a large scale on ships of internationally renowned shipping companies such as the Mediterranean in Switzerland..4 percentage points, setting a new historical high. The core indicators such as the number of high-tech enterprises, technology transaction volume, and the number of top talents have doubled in three years. Ningbo has also deployed and promoted the “Tree Planting Project” for scientific and technological innovation in the form of a decision made by the Municipal Party Committee for the first time, initiating the construction of three major scientific and technological innovation highlands: new materials, industrial internet, and key core infrastructure. The Yongjiang Laboratory has been approved as a Zhejiang Provincial Laboratory for New Materials, and 46 high-energy industrial technology research institutes have been introduced and built with a total of 71.
