2. Not necessarily - it's probably best just dumping the excess wind.

Building more capacity that is more widely distributed is likely to be less expensive than using hydrogen and will have added benefit of pushing fossil/nuclear offline.

Also, if storage is required, there are a number of alternatives that are probably going to be better than hydrogen. Batteries via V2G comes to mind, along with several new, simple technologies that are upwards of around 80% round trip efficiency.

Hydrostor Wants to Stash Energy in Underwater Bags

Submerged bags of air could turn wind and solar power into round-the-clock resources

Underwater Energy Storage – Hydrostor
November 30, 2015Energy Matters

The world’s first underwater compressed air energy storage system is up and running and is claimed to be one of the cheapest forms of energy storage available.

Located in Toronto Island, Canada; the system’s underwater air storage component is located 2.5km off the shore of Lake Ontario – one of the five Great Lakes of North America.

How Hydrator Works
An air compressor converts the electrical energy into compressed air pressurized to the same level found at depth where the accumulators (balloons or solid containers) are located; which can be 50-500 meters below the surface of a body of water. The compression process also creates heat, which is captured for use during the generation phase...

Or how about on-shore at one of Isentropic's thermal storage (rock battery) facilities?
