Anthracite Anthracite Anthracite, often referred to as hard coal, is a hard, compact variety of coal that has a submetallic luster. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coal. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 92% and 98%. The term is applied to those varieties of coal which do not give off tarry or other hydrocarbon vapours when heated below their point of ignition. Anthracite ignites with difficulty and
Carbon capture and storage dioxide per year. Phase 1 of this project was the construction of a 250 MW IGCC demonstration plant for R&D that began in 2009 and was set for completion by 2012. Phase 2, which is still in progress, involves construction of a pilot plant that produces electricity from hydrogen and captures carbon dioxide for industrial use. CHNG has also partnered with American coal company Peabody Energy on this project. Climeworks opened the first commercial direct air capture plant in Zürich, Switzerland. Their process involves capturing carbon dioxide directly from ambient air using a patented filter, isolating the captured carbon dioxide
