Concentrated Solar Power Mated With Biogas

Here’s an article on the use of natural gas mated with concentrated solar power (CSP).  The central issue facing CSP is achieving temperatures high enough to minimize thermodynamic heat losses, and, for most configurations, that means coupling the troughs and towers with a small amount of gas.  Since using any amount of gas diminishes the plants’ qualifications as “renewable,”  the article contemplates the use of biogas.
