Hydrogen Production Cost from Steam Methane Reforming.
The cost of “grey hydrogen” produced through the methane reforming is about 52-68% dependent on the price of methane feedstock. Therefore, considering the steam methane reforming (SMR) reaction,
it is easy to calculate the methane necessary for the production of a specified amount of hydrogen and its relative cost. At these links you can find the current price of methane in Italy and in EU. By inserting the actual price of methane you can obtain the corresponding hydrogen cost.
*Density of Methane of 0.668 kg/m3 in standard normal condition of 20°C and 1 atm has been used for calculation.
*Green Hydrogen produced with a 49.3 kWh/kg efficiency alkaline electrolyser (67.7%)
