Hydrogen supply for cold, overcast and windless days
Just like other fossil fuels, natural gas is located underground in large fields, so that constitutes the majority of our supply straight away. Underground salt domes, such as those found in the north of the Netherlands, are also used as buffers for periods when the demand is greater – a sort of grab stock.
On a cold, overcast and windless winter’s day, little sustainable energy can be obtained from the wind and sun, but the demand is great. On the flip side, more sustainable energy can be produced on a sunny and windy day than there is demand for it. Energy, in the form of hydrogen gas, should also be stored in a buffer stock in order to meet the changing demand.
