Hybrid Geo-Solar GeoVision Case Study Analysis: CSP power plant with geothermal boiler feedwater heating

While stand-alone geothermal power plants provide reliable 24/7 baseload operation, most systems are subject to slow resource decline, and air-cooled plant performance suffers in hot weather. Stand-alone solar thermal power plants operate using a consistent, albeit intermittent, solar resource that requires thermal storage for reliability. Hybrid geothermal-solar power plants offer a number of potential advantages including boosted power generation during daylight hours when demand is typically greatest, the ability to share a common power block, and no requirement for thermal storage. The GeoVision hybrid systems analysis focused on aspects of hybrid technology that can increase the utilization of geothermal energy. Important aspects of the hybrid systems analysis therefore include evaluating conditions where hybrid technologies could decrease the costs of geothermal power generation and/or increase the viability of low temperature geothermal resources.

Machining of Alloy 740H for Preliminary CSP testing

INL will begin work studying the mechanical properties of 740H. A plate was secures for preliminary investigation, which will be sent to Metcut to machine both creep and fatigue specimens. The specimens machined herein will be used to characterize the creep and cyclic behavior of the Inconel alloy 740H plate. Data generated from testing of the specimens machined herein will provide essential characterization on allowable stresses for alloy 740H
