Processing or developing the processing of ash and slag [the mineral non-combustible part of coal – ed.] offer additional opportunities for coal-based electricity generation. This is particularly important in light of the climate agenda. <...> A new beginning, new technologies, new technological transformations... There are two important aspects when considering using ash and slag, when using this by-product. The first aspect, which I would focus on, is the potential to reduce greenhouse gas emissions. <...> Using ash can help reduce greenhouse gas emissions at a ratio of 1:1, i.e., for every tonne we use, we can reduce greenhouse gases by a tonne — Irina Zolotova, Director of Center for Sectoral Research and Consulting, Financial University under the Government of the Russian Federation.
We have carbon-capture technology. And we use it for new projects, and at other enterprises. Carbon monoxide is used to make metal, so in effect, we are expanding our portfolio. We are increasing production of methane, we are conducting comprehensive research, and we are studying the entire chain – every product. And we are coming up with uses for things that were previously considered to be by-products — Sri Ram Chandra Prasad Singh, Minister of Steel of the Republic of India.
Combustion and coal preparation technologies will continue to improve, as of course will coal gasification technologies, most importantly. There will be new technologies — Zinfer Ismagilov, Director, Institute of Coal-chemistry and Material Science of the Siberian Branch of the Russian Academy of Science.
