The use of hydrogen as an energy source is advantageous because its combustion processes only produce water vapor, but not carbon dioxide. This excess can be stored in underground gas storage facilities, where it delivered mixed with natural gas. In gas- and oil industry the formation hydrate crystals cause significant damages. A huge amount crystal formed, plugs pipeline. Like gas, occurs case...

A bomb calorimeter is an apparatus used for measuring the performance of coal in term of heat of combustion. Recent awareness has been created regarding uncertainty of measurement, due to mainly two reasons. Laboratory accreditation, which has steadily been on the rise, which requires a estimation of uncertainty of measurement particularly in the field of calibration. Second, increased maturity...
