Bio Diesels making a comeback?

Are bio diesels making a comeback? The recent initiatives around energy efficiency are leading to a renewed focus on rail transportation of goods (see Berkshire Hathaway's recent investment) and diesel in general.
At least one company thinks so: Valero has just made a big investment in jatropha. We had heard of this plant a few years ago when it was going to the solution to the world's fuel problems followed by a couple of years of silence and unkept promises.

This plant is also partly causing the issue of land grabbing in Africa for both cultivable land as well as waste lands. Other reasons being dearth of cultivable land in the Middle East, desperate measures to support burgeoning populations in developing countries and opportunism.

Seems a far cry from last year's fears of European dependence on Russian gas and being held hostage by a great angry bear.
