Title: Development of a Green Parabolic Trough Collector

Abstract

This report describes in detail a research project that assesses the potential of a parabolic trough solar collector with a lumber construction to meet ambitious performance, cost, and durability goals. Instead of exploring lumber as a general question for solar collectors, the project focuses on the design optimization, laboratory testing, outdoor testing, and economic modeling of a particular scale of parabolic trough, namely, the 6m aperture and 12m long module that has become the standard in the utility-scale power plant market. As will be appreciated in the report, it is also a scale that matches well the capabilities of lumber as a structural material and the commonly available cross sections. The design and its analysis extend far beyond traditional considerations for wooden structures in the built environment, and includes a computationally efficient coupled structural-optical simulation and the empirical characterization of joint stiffness at small deformations. Laboratory testing is used to characterize cyclic joint behavior, accelerated weathering, and to validate the simulation used as the basis for building a full-scale prototype. The construction and outdoor testing of this prototype is described. A total installed cost model of the collector is presented and the impact of the cost is seen in themore » context of a full plant techno-economic model. The results of this model in combination with the experience with the first prototype suggest that with improvements to the design and assembly process, this collector type has the potential to lower the levelized cost of heat for industrial solar steam plants used for process heating or cogeneration.« less
