Last week our biennial international conference on clean coal technologies, ‘CCT2017’, took place very successfully in Cagliari, Sardinia, with the great help of local research institute and hosts Sotacarbo. With around 250 delegates representing industry, academia, and government from 31 different countries, this was one of the biggest CCTs of recent years, highlighting the ongoing global relevance of the coal industry and the growing need for technologies which can reduce its environmental impact. The conference covers 27 technical sessions over three days, as well as keynotes, plenaries and panels, so in this blog I can only provide a small glimpse . . .
