The document compares solar trough and CLFR systems across various metrics. Solar trough systems require more land area per megawatt hour generated and have higher costs due to higher fluid friction losses, tracking power needs, universal joint leakage, and receiver thermal shock and cracking issues. CLFR systems have lower land area needs, costs, maintenance requirements, and pressure needs while allowing schedule operation and modular design. Both systems provide direct steam and thermal storage but CLFR does not require steam pressure storage.
