避免除役後堆出百萬噸離岸風電廢棄物,西門子歌美颯推世界首個可回收再利用風機葉片!(09/08/2021 TechNews科技新報)
(作者 Daisy Chuang)風機大廠西門子歌美颯(Siemens Gamesa Renewable Energy)7 月宣布環保目標,矢言在 2030 年 100% 回收風機葉片,2040 年更實現 100% 風機回收,實現循環經濟,而現在西門子歌美颯捎來喜訊,他們已經研發出可回收的風機葉片了。
現在的風機不容易回收嗎?風機內有 8 千多個零件,壽終正寢後將會拆解並運送至指定的地點回收處理,只是風機葉片由難回收的複合材料所製成,尤其是玻璃纖維增強型複材(Glass-reinforced polymer composites,GRP),在成本與便利性考量下,其實大多焚化或直接掩埋處理。
因此未來隨著離岸風電全球裝置量愈來愈高,若沒找到妥善回收再利用辦法,帶來龐大的環境負擔同時,風機商的壓力將愈來愈大──畢竟一點也不環保。先前蘇格蘭斯特拉斯克萊德大學更預測,2030 年每年廢棄葉片可能會到 40 萬噸,2050 年增加到 200 萬噸。
根據西門子歌美颯說法,這是世界上第一個可回收的商用離岸風機葉片。新葉片長約 81 公尺,採用全新樹脂,退役後的葉片也可以回到產業鏈。葉片中的樹脂能與其他材料模組分離,與傳統風機葉片回收技術相比,過程也能較為「溫和」,可以維持材料的特性,分離後才料仍可再回到製程中。
目前西門子歌美颯已獲得到三家公司的訂單,RWE、EDF Renewables 和 WPD 都表示將在未來的離岸風電風廠使用這種葉片,西門子歌美颯發言人表示,未來也會在案場訂單中提供新的葉片選項。其中 RWE 將在德國 Kaskasi 離岸風場率先安裝新葉片,預計將於 2022 年安裝。
近年來許多能源公司投入風機葉片回收研究,6 月時離岸風電大廠沃旭能源(Orsted)已提出 3R 願景,表示一旦旗下風場的風機退役,將重複使用(reuse)、回收(recycle)、再生(recover)所有的風機葉片,認為自己有責任尋找葉片回收方案。
隨後 GE 再生能源和全球最大的水泥製造商法基霍爾希姆也簽署 MOU,攜手尋找風力發電的「循環經濟解決方案」。
今年 4 月時,學界與工業界也發起「DecomBlades」計畫,包括沃旭能源、LM Wind Power(GE 再生能源旗下)、維斯塔斯、西門子歌美颯、FLSmidth、MAKEEN Power、HJ Hansen Recycling、丹麥能源集群(ECD)、南丹麥大學(SDU)和丹麥技術大學(DTU),將一同為風機葉片回收找出解方與打造價值鏈。
2020 年 12 月 GE 再生能源與環境解決方案服務業者威立雅北美公司(Veolia North America,VNA)簽署長期協議,回收美國陸上風機的葉片。丹麥風機巨擘維斯塔斯(Vestas)也在 2020 年 1 月宣布,目標在 2040 年研發出零廢棄物(zero-waste)風機,希望未來的風機壽命告終後,葉片還可以回收再利用。

◤Taiwan can’t build renewables if we can’t balance them◢
Taiwan wants to build a decarbonized future, but this will become a reality only if it could consume renewable energy at its full potential. Virtual Power Plants (VPPs) represent a form of power flexibility available today.

renewables 在 Xiaxue Youtube 的最佳解答
Many people (like 5!) asked me about my views on climate change so here it is! The video can be pretty tedious if climate change isn’t a topic you are interested in in the first place, but I felt that climate change is such a complicated topic that without a long ass video I can’t really properly explain my disdain for Greta Thunberg’s speech.
Yes I know she’s a teen and she’s autistic but it doesn’t change the fact that she’s preaching a dangerous message that will have serious negative economic impact, especially on the poor and for poorer countries.
If you can’t be bothered to watch the entire video, here is the TDLR: The climate crisis cannot be solved simply blaming people for their greed. Everything comes at a cost and the current climate situation is the price to pay for the peace and prosperity that we all enjoy. Everyone is to blame. To implicate change comes with cost, which doesn’t mean we shouldn’t try to improve the current climate situation, but people should be made aware of the cost first. Actually I can’t really summarize it just watch the video goddammit
