That is something I mentioned in another comment below.

It's still an open question whether conversion to methanol, transportation, and sale will be cheap enough to actually generate a profit. It the real world, it might simply cost too much or be too dirty of a conversion that the numbers don't add up.

In this case, then we will still be better off just burning it efficiently on site.

Synthetic methane has very controllable levels of contaminants. If this can use an abundant catalyst or small enough amounts of rare elements it's a good steptowards powering a lot of existing infrastructure with sunlight.
