According to the IEA (International Energy Agency) [1] the current (well, as of 2018) production cost of hydrogen using methane as a feedstock is $ 0.9-3.2 /kg, while using renewables is 3.0-7.5 USD/kg. However, as the cost of renewables goes down, there will be plenty of places in the world where the cost of producing H2 (including transportation to the place of use) will be below $2/kg, so quite competitive with methane (not to mention that the price of methane is about twice now what it was in 2018).
