In Denmark we could split water through hydrolyse whenever there is over-production from windmills. This over-production is something that we currently pay our neighbours to receive. In addition the heat produced can be used as district heating, making it less of an issue that it is less efficient to produce hydrogen.

From what I've heard, the capital costs of electrolyzers are currently far too high to make intermittent hydrogen production economical. Hopefully that will change, and intermittent usage will eventually be about the same cost as running continuously.
Newer wind turbine contracts make the turbine owners turn off their engines.
And it is only very few hours of the year that the prices turn negative anyway. You can't base anything off that. It's just not worth it.
