Abstract
Popularity of methane-containing gaseous fuels has slowly been growing since their appearance, especially in the last decades. Occasional non-availability of liquid fossil fuels, the necessity to reduce the transportation costs and to improve the air quality are the basic factors which stimulated development of gas utilization technologies - from accumulation, compression and deflation of gas to its usage in internal combustion engines. Since then different solutions have been offered, and the authors are reviewing them - from the first use of natural gas to nowadays.
