- 摘要
- 在本世紀中，化石燃料仍是人類社會能源供應之主流；其中以煤炭為大宗，其蘊藏量佔地球資源50%以上，預估可使用超過110年。煤炭供給29%全球初級能源，其總發電量佔比高達41%。然而，大氣中二氣化碳(CO2)濃度攀升無可避免，除非能源系統降低其碳排放。此外，煤炭利用向來被視為環境衝擊的主要元兇，排放大量的污染物，如NOx、SOx、懸浮微粒等。當前可預見人類對煤之依賴不可能大幅戒絕，但可使其潔淨利用；換言之，淨煤技術將容許我們持續使用地球的煤炭資源。溫室氣體減量須經由各類技術組合方可克竟全功，而煤炭潔淨利用可提供重要貢獻，亦為本文之主題。台灣為人口稠密、資源缺乏之島國。在2015年，我國進口能源依存度為97.53%，而44.58%發電量來自燃煤，其二氣化碳排放占總量比例達三分之一。有鑑於此，煤炭潔淨利用實為一項必須高度優先關注之議題。我國於2015年正式通過「溫室氣體減量及管理法」，條文中明確規範我國溫室氣體長期減量目標為2050年的溫室氣體排放量要降為2005年的50%以下。可預期我國產業對於淨碳能源之應用亦將有大量之需求出現。因此，以永續方式利用煤炭並將環境衝擊減少到最低限度之淨煤技術將是絕佳選項；預期可以利用較少的投資創造更大之經濟價值，以確保邁向一個永續之未來。

- In the 21st century, the mainstay of energy production will remain predominant with fossil fuels; while coal is the most abundant reserve, accounting for over 50% of global resources that may last for more than 110 years, at the current mining production levels worldwide. However, increased concentrations of carbon dioxide (CO2) and pollutants in the environment are inevitable unless energy systems reduce the emissions to the atmosphere. Furthermore, mitigation of greenhouse gas (GHG) emissions has been essential to sustainability, and requires various portfolios. It is foreseen that substantial reduction of human dependence on coal is impossible today, but it is possible to make it cleaner. In other words, clean coal technologies (CCT) will allow us to continuously utilize world’s coal resources. According to the statistics of IEA (International Energy Agency), the top ranking three categories in CO2 mitigation portfolio are renewables, end-use efficiency, and CCS (carbon capture and storage); while clean utilization of coal can make significant contribution to the last two options above, and will be the major focus of this paper. Taiwan is an isolated island with dense population and limited natural resources. In 2015, the dependence on imported energy in Taiwan is 97.53%, mainly fossil fuels. The share of electricity generation by coal remains 44.58%, and the CO2 emissions from domestic coal power account for about one-third of the present national total. Hence, clean utilization of coal resides in a high-priority issue in Taiwan. The “Greenhouse Gas Reduction and Management Act” has been issued in Taiwan since June 2015, which sets the target to reduce GHG emissions to 50% of the 2005 level by 2050. It means that lower carbon-containing sources or advanced low-carbon energy technologies will be major options to mitigate CO2 emission. From the perspectives of energy security, environmental protection and economic development, extensive viewpoints and development trends are addressed in this work. Moreover, progressive bullet points are proposed to implement clean utilization of coal. In summary, CCT, utilizing coal in a sustainable way and minimizing its impacts to the environment, will be the ideal candidate for the economy to create more value with less input.
