Yes, green hydrogen is currently a lot more expensive than natural gas. That is because natural gas is exceptionally cheap in the Netherlands and the resources for hydrogen production are still expensive. The expectation is that the price of natural gas will increase in the coming years, for example due to levies and developments on the international market.
As yet, there isn’t an economy for green hydrogen. The cost price will only decrease once the scale of green hydrogen production increases and the demand increases. Europe is already developing plans for demand and supply. Some prognoses even assume that by mid-century, the prices of hydrogen and natural gas will not be that different.
