Rock massif observation from underground coal gasification point of view [PDF]
Metalurgija, 2009 The Underground coal gasification (UCG) of the coal seams is determined by suitable geological structure of the area. The assumption of the qualitative changes of the rock massif can be also enabled by application of geophysical methods (electric ...

Advanced geophysical underground coal gasification monitoring
Mitigation and Adaptation Strategies for Global Change, 2014 Underground Coal Gasification (UCG) produces less surface impact, atmospheric pollutants and greenhouse gas than traditional surface mining and combustion. Therefore, it may be useful in mitigating global change caused by anthropogenic activities. Careful monitoring of the UCG process is essential in minimizing environmental impact.

Solar‐Powered Green Hydrogen from Electrolyzer (PV‐H2): A Review
Solar RRL, Volume 9, Issue 14, July 2025.This review highlights solar‐powered hydrogen production using electrolyzers. While direct photovoltaic (PV) coupling reduces costs, it poses stability challenges. Emerging PV types like floating PV offer integration benefits. However, large‐scale deployment faces issues like land use, high costs, and underexplored long‐term electrolyzer performance ...

Deviated and Horizontal Wells Drilling Technology in Coal Seams [PDF]
Acta Montanistica Slovaca, 2006 Drilling in coal seams becomes more and more popular at the present time, especially due to the fact that coal can be exploited not only by subsurface or surface mining methods but also in much cleaner way – underground coal gasification.
