HYDROGEN IN MUNICIPAL ENERGY

Keywords: hydrogen, thermophysical properties, effectivnes

Abstract

The use of hydrogen in the municipal energy sector is currently inappropriate due to its high cost. Production of hydrogen by electrolysis requires more energy than it is emitted during its combustion. Thermophysical properties of hydrogen and natural gas are compared. Heat value of hydrogen in a unit of volume is 3.3 times lower than that of methane. The cost per unit of energy in hydrogen is more than 10 times higher than in natural gas. Distribution gas networks are not suitable for transportation of pure hydrogen. The possibility of transporting hydrogen in mixtures with natural gas is being studied. The efficiency of fuel use in a heating gas boiler decreases with increasing hydrogen concentration in a mixture with natural gas up to 50 %. The concentration of nitrogen oxides does not depend on the hydrogen content in the mixture. Bibl. 4, Table 1.
