Solid fuel purposes, such as refining metals. Coal is the largest source of energy for the generation of electricity worldwide, as well as one of the largest worldwide anthropogenic sources of carbon dioxide releases. The extraction of coal, its use in energy production and its byproducts are all associated with environmental and health effects including climate change. Variations such as smokeless coal can be formed naturally in the form of anthracite, a metamorphosed type of coal with a very high carbon content that gives off a smokeless flame when set alight. Coke is a fuel with few impurities and a high carbon
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
