Large scale. That's the goal. Transportation (and by that, I mean goods, we rely on trucking for the majority of our food and consumer goods) relies on crude oil, it will take god knows how long to ween off of that. Large scale production is the name of the game, not ideal lab situations.
But, will the resultant product replace all the other stuff we get from regular crude? Petrochemicals, asphalt, plastics... All those things that are the big ticket items that off set the cost of making gasoline and diesel?

Exxon Refocusing Algae Biofuels Program After $100 Million Spend - Bloomberg
I'm generally pretty skeptical of biofuels and petroleum conversion technologies. The former for reasons others have elaborated on already (lack of real economy and the impact it has on the agricultural market) and the latter because there are enormous hurdles when it comes to translating these laboratory breakthroughs into mass production. They are years if not decades away from viability and there are other options that are in my opinion much more promising and already further along. I think no matter what we're looking at a conventional natural gas, coal, and petroleum future for at least the next twenty to thirty years and likely more. However in the interlude I think solar will continue to mature, new nuclear techniques will be adopted in developing countries and more plants will be built, and batter technologies will improve dramatically allowing for a shift in emphasis to electrical generation as opposed to transportation fuels (think Tesla but 15 years down the road and imagine what you might see).
