因應2050淨零目標 科技部拚氫能等新技術落地

2050淨零排放路徑定案,科技部主導的「淨零科技行動方案」也開始啟動,主要項目包括氫能、儲能裝置、智慧電網等,並爭取和日本、澳洲跨國合作氫能,和德國合作儲能電池。
科技部次長林敏聰表示,2030年之前,淨零排放可以靠現有技術去達標,但2030年之後就得靠新科技才能實現,目前最重要的,就是朝儲能設備、氫能、智慧電網等技術發展。2050淨零轉型主要計畫預估2030年前需9,000億元,其中規劃再生能源及氫能2,107億元、電網及儲能2,078億元、節能及鍋爐汰換1,280億元及運具電動化1,683億元。
以PCB製造的產業特性,約七成的碳排放是屬於ISO14064定義的Scope 2間接排放,其中消耗的能源型態以外購電力為主,因此綠電的使用是PCB廠商達到淨零碳排的主要方案之一。但鑒於目前台灣綠電供給太偏重於光電和風電,多樣性不足且進度緩慢,除了讓廠商擔憂未來是否能穩定供電外,也容易造成供需失衡與綠電價格混亂。所以部分有資源的廠商開始規劃自主發電的方案,以降低現階段過度仰賴外購綠電的風險,包括像是氫氣發電、廢棄物燃燒發電等,但礙於建置土地稀缺、新能源技術尚未成熟到商轉程度、以及資金投入等問題,仍處於規劃階段。
因此由科技部帶頭主導將有助於加速潔淨能源的技術開發,及早落地商轉供業者使用。但在技術成熟之前,節能仍是企業減碳的重點工作之一,而為了達到有效節能,企業首要得進行自身工廠的碳排總體檢,了解工廠前幾大的耗電與碳排點為何處,才能對症下藥,實現淨零轉型的第一步。
