DOE EERE Technologist in Residence Pilot

The EERE Technologist in Residence pilot program is intended to catalyze strong national laboratory–industry relationships that result in significant growth in high-impact collaborative R&D. This pilot program’s goals are to increase collaborative R&D between national laboratories and private-sector companies and develop a streamlined method for companies to establish long-term relationships with national laboratories that result [...]

CFD-Populated Empirical Turbine Wake Model

The DTOcean team is developing a fast-running, easy to use current-energy capture (CEC) array spacing tool that considers tidal array performance vs efficiency. In support of this effort, Sandia has been assisting in developing the device wake modeling submodule that determines a tidal turbine’s wake properties (i.e., wake growth and dissipation). Initial efforts were focused on [...]

Developing a Fast-Running Turbine Wake Model

As part of the international collaboration for DTOcean, a project aimed at accelerating the industrial development of ocean-energy power-generation knowledge and providing design tools for deploying the first generation of wave and tidal energy converter arrays, Sandia is developing a fast-running current energy converter (CEC) wake-interaction model. Toward this end, Sandia has begun implementing parametric [...]

Final FY14 Measurement Campaign in Roza Canal, Yakima, Washington

Uncertainty exists regarding the effects on local water operations of deploying a current energy converter (CEC) turbine in an irrigation canal for the purposes of producing electricity via the canal's flowing water. Budi Gunawan and Guild Copeland (in Sandia’s Water Power Technologies Dept.) and Derek Belka (a Water Power Technologies Dept. summer intern student) joined [...]

Inter-Agency Agreement Signed between DOE’s Wind and Water Power Program and Carderock

The Department of Energy (DOE) has launched a multiple-year effort to validate the extent to which control strategies can increase the power produced by resonant wave-energy converter (WEC) devices. Many theoretical studies have shown a promise that additional energy can be captured by controlling the power-conversion chains of resonant WEC devices. The numerical models employed [...]

Sandia Publishes Five Reports on the Environmental Effects of Wave-Energy Converters

Example of Hydrodynamic modeling showing wave height and circulation patterns in Monterey Bay, CA. Since 2010, Sandia has been studying changes in wave propagation due to the operation of wave-energy converter (WEC) arrays. This work has primarily focused on applying and enhancing the-open source spectral wave model SWAN (Simulating WAves Nearshore). The five [...]
