【正文】 可持續(xù)發(fā)展的煤炭利用 Transforming Coal for Sustainability 國合會(huì) 能源專題組 TFEST of CCICED 中國目前的能源系統(tǒng)是不可持續(xù)的 The energy system in China is unsustainable 將來面臨的風(fēng)險(xiǎn)： ?過度依賴石油進(jìn)口 ?環(huán)境狀況迅速惡化 ?溫室氣體減排代價(jià)高昂 ? China will bee overly dependent on oil imports as a result of rapidly growing demand for liquid fuels ? Severe environment damages caused by direct bustion of coal ? China will not be able to make its contribution to mitigating greenhouse gas (GHG) emissions under low cost. 中國一次能源將來仍將以煤炭為主 The coal is the main part of primary energy in China T o t a l P r i m a r y E n e r g y S u p p l y0204060801001201401601995 2020 2020 2020 2020 2020 2025 2030 2035 2040 2045 2050 1995 2020 2020 2020 2020 2020 2025 2030 2035 2040 2045 2050B A S E C A S E U p d a t e d m o d e l U p d a t e d A d v T e c h w i t h A l l C a p s a n d L o w N u c l e a rExajoulesEF F I C I EN C YR EN EW A BL ESN U C L EA RC BMN G A SO I LC O A LG a s i f i ca t i o nC O A LC o m b u s t i o nB a s e T e c h n o l o g i e s A d va n c e d T e c h n o l o g i e sSO 2 , 3 0 % O i l amp。 G a s , 6 6 G t C C a p s 以合理成本降低上述風(fēng)險(xiǎn)的方案 To mitigate these risks at reasonable cost ? 中國能源模型分析表明，面對(duì)這些風(fēng)險(xiǎn)，傳統(tǒng)的技術(shù)方案無法解決問題。 ? 通過采用煤炭現(xiàn)代化利用的戰(zhàn)略能夠以合理的代價(jià)降低上述風(fēng)險(xiǎn) ? The business as usual mode can’t solve the above mentioned problem . ? Through modernization of coal utilization, the above mentioned problems could be solved with reasonable cost. 煤炭現(xiàn)代化利用的含義 Meaning of Modernization of coal utilization ?煤炭的現(xiàn)代化 是指通過煤氣化技術(shù)來生產(chǎn)熱能，電力，運(yùn)輸用清潔燃料，炊事用燃料等，即多聯(lián)產(chǎn)能源系統(tǒng)。 ? Modernization of coal utilization——large scale gasification of coal and coproduction of liquid fuels(methanol, dimethyl ether, etc), other valueadded chemicals and electric power. If necessary, syngas and heat for residential use could also be provided. It is socalled polygeneration system. 采用先進(jìn)技術(shù)方案的效果 The effect of Advanced Technologies Scenario ? 成本與傳統(tǒng)技術(shù)方案相當(dāng) ? 煤炭開采量與傳統(tǒng)技術(shù)方案相當(dāng) ? SO2的排放從 1995年的2370萬噸下降到 2020年的 1620萬噸、 2050年的880萬噸。 ? 石油與天然氣進(jìn)口量限制在總消耗量的 30%左右。 ? 累計(jì) CO2排放量少于 660億噸碳 ? Provides the same energy services at about the same cost as the Base technologies strategy ? SO2 emissions are reduced from Mt in 1995 to Mt in 2020 and Mt in 2050 ? Impor
