Concentrated Solar Power Fluids Need to Be Monitored Regularly for Degradation

The most common heat transfer fluid (HTF) used in parabolic trough concentrated solar power (CSP) plants is a synthetic organic mix of 73.5% diphenyl oxide and 26.5% biphenyl (BDO). This HTF is used to transfer the heat from the solar collectors to the power cycle. Like all HTFs, solar fluids [...]
