Developing high-efficiency, low-carbon, clean coal in china
Issue 02/2015 In the last few decades, China has dramatically expanded access to energy and, as a result, has achieved nearly universal electrification (Figure 1). Although this accomplishment is notable, China’s energy mix is facing several pressing issues with important domestic and global implications. China is coal-rich and, for this…

Climate-friendly use of coal in power plants and in energy-intensive industrial facilities with carbon capture including the CO2 disposal in the methanol path
Issue 02/2015 Every CO2 reduction strategy should commence with the increase in efficiency of existing power plants followed by investments in state-of-the-art technologies and most advanced plants. EURACOAL’s three step strategy therefore starts in a logical sequence with the replacement and modernisation of existing power plants. In a second step…

Constructing underground water barriers in areas subject to ground movement – a real engineering challenge
Issue 02/2015 Between 2011 and 2014 two new high-pressure water barriers were constructed at Ibbenbüren Mine, RAG Anthrazit Ibbenbüren GmbH, to provide a long-term seal capable of resisting the ground movements expected as a result of the planned extraction of the Beustfeld panel. Two water stoppings had already been erected…
