Maturity Analysis of Hydrogen Production Technology Based on Patent Perspective
In order to respond to the national"dual-carbon"goal,promote the development and use of clean energy,and rationally plan the layout of hydrogen production technology routes,the initial patent data were firstly processed,a measurement data set was constructed,and the value of technological maturity was calculated based on the constructed measurement index system;secondly,the technology life cycle curve was fitted according to the value of technological maturity;finally,a comprehensive analysis of technological maturity was carried out in terms of technological application breadth,technological advancement,technological competition potential,and technological influence.Secondly,the technology life cycle stage of each hydrogen production technology is determined by fitting the technology life cycle curve based on the technology maturity value;finally,the technology maturity is comprehensively analysed in terms of the breadth of technology application,technological advancement,technological competition potential and technological influence.The results showed that the most commonly used coal gasification hydrogen production technology entered a period of decline,while electrolytic water hydrogen production entered a stage of maturity in recent years with rapid technological development,and was expected to grow rapidly into a mainstream hydrogen production technology route in the coming period.China should focus on hydrogen production routes with greater technological potential and achieve a green and efficient hydrogen production structure through gradual substitution to help transform the energy structure.
