為了解決環境汙染、生態惡化,以及關注永續發展、環境保育以及節能減碳等等相關的問題,在此背景下綠色科技、綠色能源的概念應運而生。其中海洋再生能源因具有「就地取材、因地制宜」之優點,已被認為是未來最具開發潛力且符合綠色理念的能源之一。而台灣的風力強度不高;太陽能與生質能的發展,受限於土地面積的因素,發展也有困難。地球有近70%是海洋,台灣是屬於一個海島型國家,台灣擁有的海洋資源相對來說可是比許多國家要多得多。 本研究透過專利分析來了解綠色海洋能源科技的發展趨勢,主要分析以歐洲專利局的Y02歐洲專利分類(新技術分類)下有關海洋能源類別的專利;個別探討其中之5項分類號的專利趨勢,也以技術吸引力分析來判斷哪項分類號技術最有相對吸引性,最後反觀台灣之發展也與海島型國家做比較。研究結果顯示綠色海洋能源科技在2006年後專利數量上增加的表現明顯。綠色海洋能源科技之類別中以鹽度梯度技術領域比較成熟,而海洋熱能轉換技術領域最具潛力。台灣在綠色海洋能源技術類別中屬於較弱勢的國家。
In order to solve the environmental pollution, ecological degradation, and attention to sustainable development, environmental conservation and Carbon Emissions Reduction Resolutions, we have concept emerged to develop on issues related to green technology, green energy concept emerged in this context. Ocean green energy has "local materials, local conditions" advantages, it has been considered one of the most potential for development and the energy of the green concept. Wind strength is not good in taiwan, and the development of solar energy and biomass energy have to factors of limited land area, so development is difficult. Earth nearly 70% of the ocean, Taiwan is an island country, so have ocean resources much more than many countries. This paper studies the Y02 ECLA ( unofficial classification ) EPO. This paper through patent analysis to understand the technological trends of the green ocean energy. The results show that ocean green energy technology, that number of patents increased significantly in 2006. Green ocean energy technology category in the salinity gradient technology is relatively mature, and ocean thermal energy conversion technology the most potential in the field, andTaiwan belonged to the category of vulnerable green ocean energy countries.
