基于专利信息的海洋温差能发电技术成熟度预测及关键技术领域分析

Maturity prediction and key fields analysis of ocean thermal energy conversion technology based on patent information

以德温特创新数据库和其他科技文献获得的专利信息为基础,拟合出了基于Logistic型S曲线的海洋温差能发电技术成熟度预测模型。分析了海洋温差能发电的技术发展现状,总结出了海洋温差能发电的关键技术领域和走向商业化应用过程中所面临的主要技术挑战。从技术成熟度分析曲线上看,海洋温差能发电技术刚刚从技术萌芽期步入技术成长期,与快速发展的海上风电相比,技术进展较为缓慢,技术成熟度依然处于相对较低的水平;热力循环、换热器、能量转换装置、海水泵、平台载体及定位、冷水管、冷水管和平台之间的连接等技术是海洋温差能发电的关键技术领域。

Based on the patent information obtained from Derwent innovation database and other scientific and technological literatures,the maturity prediction model of ocean thermal energy conversion(OTEC)technology based on logistic S-curve is fitted.This paper has analyzed the development status of OTEC technology,and summarized its key technology fields and the main technical challenges in the process of commercialization.From the perspective of technology maturity analysis curve,OTEC technology has just stepped into the technology growth stage from its embryo stage.Compared with the rapid development of offshore wind power,the technology progress of OTEC is slow,and the technology maturity is still low.Thermal cycle,heat exchanger,energy conversion device,sea water pump,platform structure and its positioning,cold water pipe,and the connection between cold water pipe and platform are all the key technology fields of OTEC.
