Another looks at liquid fuels from the sun versus lithium batteries.
Here it is continued
Renewable diesel, unlike biodiesel, consists of carbon and hydrogen atoms onlyjust like petroleum diesel. In last month’s issue of Diesel Power, we described two different processes of producing renewable diesel (a drop-in fuel). The first method was called Fischer-Tropsch synthesis. This involves gasifying the biomass, turning it into waxes, and then further polishing it with hydrogen gas (hydrocracking) to form pure hydrocarbons. The second method we described involves genetically modified yeast and sugar. The more I look into this subject, the more promising it sounds, and the more mind-blowing the possibilities become.
On the other hand, Hellyer said CSP with storage offers benefits that other renewable energy technologies cannot yet beat. “It can substitute coal and be used for baseload requirements,” he said. “PV and wind have no chance of competing.”
The aritcle goes on to say
Jonathan Walters, an economic consultant previously with the World Bank and now advising a CSP developer called Nur Energie, said there’s only one way the technology can compete with PV — when it’s paired with some form of backup.
Another interesting point.
“Large-scale CSP with thermal storage is cheaper than large-scale PV with battery storage, and may remain so,” said Walters.

This aritcle says
Remote renewable power generation separated from local energy consumption (electricity + transportation fuels) • Wide spread of intermittent renewables requires bulk energy storage • Infrastructure for renewable power transmission and distribution needs to be build and will be expensive
