I find this an excellent doable and logical approach. There are huge areas of suitable desert land, in addition, the algae also generates cellular fatty acids - which can be gene tailored and have the prospect of eliminating many of the old oil industries, like palm oil. As far as I can see, the same genes used in palm trees can serve (there will be work to do - of course, to expand the repertoire to many other fats as well as many petroleum based oils. Each pond can yield a different oil, as well as many other chemicals and drugs. In truth, this is done in vats now with yeast. bacteria etc.
