On-line Monitoring of H_2 Generation and the HTF Degradation in Parabolic Trough Solar Thermal Power Plants: Development of an Optical Sensor Based on an Innovative Approach

摘要

The work presented in this paper offers a robust, effective and economically competitive method for online detection and monitoring of the presence of molecular hydrogen in the heat transfer fluids of parabolic trough collector plants. The novel method is based on a specific fluorescent sensor according to the ES2425002 patent ("Method for the detection and quantification of hydrogen in a heat transfer fluid").
