The technology for capturing and storing carbon emitted by hard-coal and lignite plants is still not commercially proven.
而从硬煤和褐煤采矿厂中发展而产生的捕捉和储存炭的技术任然没有被商业化证实。As expected, shipments of hard coals saw the sharpest retreat (-14%), as most of this supply is concentrated in flood hit Queensland.
据预测，硬煤运输最多会下降14%，大部分供应短缺集中在遭遇洪水的昆士兰地区。Solid mineral fuels - Hard coal - Determination of Hardgrove grindability index.
