The uniform distribution of natural gas over various regions distanced by thousands kilometres from gas producing sites represents a serious economical and technological problem for Kazakhstan. Taking into account that the gas transportation constitutes 70% of the overall price of natural gas, the investments into gas transport from the Caspian region to eastern and southern regions appears to be extremely expensive. Another, a priori more rentable solution might consist of using hydrogenous gas instead of methane, that can be produced from coal by degasification technique. This process may be performed directly at the central and eastern coal basins and consequently does need to transport hydrogenous gas over long distances. Such a gas, called the town or syntheses gas, represents a mixture of hydrogen (60%), methane (12%), and CO2 and CO (20%) has a high energetic potential and is frequently used as a high-performance carrier of energy capable of replacing up to 60% of the natural gas used in non-industrial activity in several countries (Davison et al. 2009).
