Because incorporating storage into the story also means brining in the cost. Many of the solutions are not cheap, dependent on specific geology, and / or have their own large carbon footprint. The only thing that solar and wind bring to the table is being very cheap, but you need to compare apples to oranges for them to stand up to other solutions. Edit: this is regional specific, but wind and solar are worthless for one to two months a year where I live - rarely much sun or wind. There's simply not enough storage to power much of anything for that long, so even with cheap storage, it's worth having options that don't rely on weather. Of course, we are nowhere even close to an ocean, so this tech isn't it, but keeping exploring options is nice.
