經濟部能源局長期推動低碳能源相關的技術研發，其中「二氧化碳捕獲與封存」便是非常關鍵的技術。能源基金支持發展之鈣迴路捕獲CO2技術，已放大至1.9 MWt試驗廠規模。其特色是結合了燃燒後捕獲之碳酸化反應與純氧燃燒之煅燒再生吸附劑技術，並利用蘊藏量豐富的石灰石(CaCO3)為原料。石灰石先經由煅燒成石灰(CaO)作為吸附劑，其有高的吸附容量，可捕獲90%以上的二氧化碳，失去捕獲活性的吸附劑可完全作為水泥生產與排煙脫硫的原料，使吸附劑幾乎完全不需要成本，亦無廢棄物衍生問題，深具發展潛力。

The Bureau of Energy of MOEA promotes relevant technology research and development of low carbon energy, among them the carbon capture and storage (CCS) is a very key technology. The energy fund supports development of the calcium looping technology for capturing CO2 in a 1.9 MWt pilot plant. The distinguished feature is the combination of post-combustion capture technology using carbonation process and oxyfuel combustion calciner for sorbent regeneration, with the abundant limestone (CaCO3) serves as raw materials. At first the limestone calcinate into lime (CaO) as the adsorbent, it has high absorption capacity and can capture more than 90% carbon dioxide. When the adsorbents lose activity and can be used as raw materials for cement production and flue gas desulfurization. The calcium looping process makes the adsorbent free and produces no materials that have extensive development potentiality in the future.
