淨零排放下氫基燃料工業燃燒應用研析

全球已有136個國家宣示淨零排放目標，我國在今年公布「2050淨零路徑規劃」，因應淨零碳排目標下短期以推動低碳燃料－天然氣或生質能應用為主。未來在燃料的取得上除以天然氣為主外，在工業及能源產業導入無碳燃料－氫基燃料是未來淨零碳排主要方向，因此短期需先針對氫基燃料搭配化石能源進行混燒特性研究，包括：（1）天然氣混氫燃燒在耐高溫材料開發、有效降低高溫NOx和有效輻射熱能傳遞等，主要進行方向，並逐步邁向氫氣專燒技術開發。（2）建立混氫的計量／材料抗氫脆特性／洩漏等輸儲基礎項目。（3）既有燃燒設備在排放上符合法規標準下，可以混合氫基燃料比例。（4）燃煤混氨關鍵技術建立與示範驗證。（5）氫基燃料安全規範與相關配套措施建立。

136 countries around the world have declared net-zero emissions targets, and Taiwan also announced the ＂Taiwan's Pathway to Net-zero Emissions in 2050＂ in this year. In response to the goal of net-zero emissions targets, the short-term focus on promoting the application of lower-carbon fuels, which refer to natural gas or biomass energy, etc. In the future, in addition to natural gas, the introduction of carbon-free fuels, such as hydrogen-based fuels, will be further the main energy direction for net-zero emissions. Therefore, it is necessary to conduct research on the co-combustion characteristics of hydrogen-based fuels and fossil energy, including: (1) High-temperature resistant materials, reducing thermal NO_x format and effective radiative heat energy transfer technologies for both of natural gas and hydrogen co-combustion and hydrogen combustion. (2) Technologies of metering the blend of hydrogen and fossil fuel, material properties of anti-hydrogen embrittlement and leakage treatment for hydrogen transportation and storage. (3) Determination of the mixing limit of hydrogen and fossil fuel adopted on the existing combustion facility and meeting the flue gas emissions requirement by environment regulation. (4) Development of key technologies for co-firing coal and ammonia. (5) Establishment of regulations for hydrogen-based fuel processing safety.
