If the future doesn't get totally stupid, there will probably be a small decline in gas stations much like in areas where industry has dropped off.
There will still be fossil based fuel for sale.
There may depending on how soon the world gets over the big misconception that fuels made from plant oils have to be bio fuels - additional bowsers for regular fuel that was created though cracking (in the same petro-refineries) organic oil as the input stock to produce an almost identical fuel to that which is made from fossil based sources - it might cost a little bit more though.
Possibly an area for refuelling liquid based fuel cell powered vehicles.
