Levelized cost of energy for a Backward Bent Duct Buoy

Abstract

The Reference Model Project, supported by the U.S. Department of Energy, was developed to provide publically available technical and economic benchmarks for a variety of marine energy converters. The methodology to achieve these benchmarks is to develop public domain designs that incorporate power performance estimates, structural models, anchor and mooring designs, power conversion chain designs, and estimates of the operations and maintenance, installation, and environmental permitting required. The reference model designs are intended to be conservative, robust, and experimentally verified. The Backward Bent Duct Buoy (BBDB) presented in this paper is one of three wave energy conversion devices studied within the Reference Model Project. Comprehensive modeling of the BBDB in a Northern California climate has enabled a full levelized cost of energy (LCOE) analysis to be completed on this device.

“…The oscillating water column (OWC), which compresses or decompresses the air in a chamber using the wave elevation to drive a Wells or impulse turbine to convert wave power. Depending on the location of installation, OWC devices can be fixed onshore [76][77][78], as shown in Figure 6a, or floating, as shown in Figure 6b [79][80][81].  Wave activated bodies (WABs), which utilize the wave excitation motions between two bodies to convert wave power into electric power.…”
