While wind is more expensive than solar, and has issues highlighted in article, the higher capacity factors, and production outside of midday, means less battery capacity is needed to serve renewables, and batteries get charged more often.
A key to bringing down transmission costs for wind, especially offshore where transmission is the highest cost component, is hydrogen production. Picking up H2, or refueling, by trucks and ships can provide cheaper energy than transmission lines. Pipelines are even cheaper with enough volume, and double as storage.

I wouldn’t say a pipe underground that you have to dig up every year to check if it’s not falling apart on it’s own is a great option
