The point is that some countries have long dark winters, often with windless spells. Some are also lowland countries with little or no access to hydro.
For green energy, you'd need to literally store months' worth of energy somehow, and the cost of doing that via batteries is prohibitive too.
I guess the hope is that storing hydrogen, difficult and expensive that it is, could be made to be more like storing hydrocarbons, basically in a hole in the ground. Then you could produce it in the windy sunny months and use it in winter.
