It's still not earning you money to spend electricity because you still have to pay the transfer fee which is around 6 cents / kWh but it's pretty damn cheap nevertheless, mostly because of the excess in wind energy.
Last winter because of a mistake it dropped down to negative 50 cents / kWh for few hours, averaging negative 20 cents for the entire day. People were literally earning money by spending electricity. Some were running electric heaters outside in the middle of the winter.
This will hopefully lead to storage methods, maybe exportable ones like hydrogen
Hydrogen is not good for energy storage. Round trip efficiency is abysmal and its incredibly difficult to store in the first place
Of course not, hydrogen is pathetic compared to batteries and similar stored mass energy solutions, but hydrogen does have its place, the future should be a mixture of different solutions because many methods have their advantages and disadvantages, but having a mixture means we can apply the best solution to the viable problems. Let's take transportation, you have a truck that earns money by travelling. If we want to transition away from fossil fuel, hydrogen makes sense over batteries that takes an hour to multiple hours to charge and the weight of the batteries reduce the overall payload of the truck.
Hydrogen has its place, and we need plenty of it in places where we don't have viable alternatives. Road transport is pretty far down that list though.
