Support for carbon capture, utilization and storage (CCUS) for coal power plants is limited, to some extent, by the high cost of electricity associated with available technologies. While a comparison of different capture methods favors oxy-combustion technology, the cost is still prohibitively...

We decompose the contribution of five drivers of energy use and CO2 emissions reductions in achieving climate change goals over 2005–2100 for various climate policy scenarios. This study contributes to the decomposition literature in three ways. First, it disaggregates drivers of energy demand...

Underground coal gasification (UCG) is promising to be an important means of meeting the increasing energy demand in several countries. UCG is inherently an unsteady process since a number of parameters, such as the growth of the cavity, inherent variation in the properties of the coal along the...

Studies on the growth of three-dimensional cavity geometries in underground coal gasification (UCG) are important in exploiting the large fraction of coal that is present in underground coal seams. In the present study, the cavity formation in UCG has been simulated using experiments carried out...

Various options are considered to reduce CO2 emissions when utilizing deep coal by applying underground coal gasification (UCG), i.e., in combination with carbonation of synthetic minerals (CaO), conventional UCG followed by ex-situ separation of CO2 and upgrading the product gas using naturally...

Underground coal gasification (UCG) is a potential clean coal technology which converts coal into combustible gas in situ. The syngas produced from the UCG process using dry air contains more steam, tar and higher hydrocarbons compared to the conventional gasifiers. The focus of the present work...

Underground coal gasification (UCG) allows for the utilization of coal reserves not exploitable due to unfavorable geology and economic boundary conditions. The present study examines underground coal gasification economics converting deep-situated coals into a high-calorific UCG synthesis gas....

Underground coal gasification (UCG) is a clean coal technology to utilize deep coal resources effectively. In-situ CO2-oxy coal gasification may eliminate the operational difficulty of the steam gasification process and utilize CO2 (greenhouse gas) effectively. Furthermore, it is necessary to...

Das Thema Nachhaltigkeit und deren Bewertung, insbesondere der ökologischen Komponente des Nachhaltigkeitsbegriffs, gewinnt auch in der Holz- und Möbelindustrie immer mehr an Bedeutung. Zugleich ist die Möbelindustrie ein nicht unerheblicher Verbraucher von Holz und Holzwerkstoffen. Für die...
