Five co-located events will showcase MHK innovation during Waterpower Week in Washington

The U.S. Department of Energy Water Power Technologies Office and national laboratories involved with marine energy research will host five co-located events from May 1—3 during Waterpower Week in Washington.

The co-located events will showcase the important work driving marine and hydrokinetic (MHK) energy innovation forward. Water power professionals and the general public can attend these particular sessions to network and discuss the future sustainability of the hydropower and marine energy industries.

Speakers from DOE and hydropower industry professionals serving as panelists will participate in the co-located events, which include the following:

Sandia National Laboratories and National Renewable Energy Laboratory (NREL)

Modeling Wave Energy Converters with WEC-Sim for Performance

Wave Energy Converter SIMulator (WEC-Sim) is an open-source wave energy converter (WEC) simulation tool developed on Mathworks MATLAB and SIMULINK platforms using the multi-body dynamics solver Simscape Multibody developed by Sandia and NREL with funding from DOE.

The WEC-Sim development team will give an overview of the WEC-Sim code, focused on its application to model the performance of WECs.

WEC-Sim has the ability to model devices that are comprised of rigid bodies, power-take-off systems and mooring systems. Simulations are performed in the time-domain by solving the governing WEC equations of motion in 6 degrees-of-freedom.

Industry and regulatory agency participants

MHK Community Outreach to Understand Data Product and Information Needs

Wind, aerospace, and automotive industries demonstrated that sharing and disseminating information in terms of data, experience, and lessons learned accelerates the pace of technology development and commercial acceptance. The MHK industry has developed a wealth of information, but much of this is spread across many locations and in disparate structures that make it very difficult for use by the broader MHK industry.

Advanced WEC Dynamics and Controls

This workshop will gather researchers and developers interested in WEC dynamics and controls to discuss ongoing work. The workshop will include focused presentations, a panel discussion and a networking session.

MHK Environmental Compliance Cost Reduction Strategies Workshop

MHK Environmental Compliance Cost Reduction Strategies project collects detailed cost estimates of the environmental compliance efforts for licensing, permitting and implementing MHK projects. With help from industry and regulatory agency participants, this project will help create an economically competitive U.S. MHK industry by reducing time and costs to achieve environmental compliance, while meeting federal, state and local regulatory requirements.

In 2017, the project team is conducting guided discussions with project developers/project leads and federal and state regulatory agencies, with a discussion guide and associated materials distributed in advance. Each sector will then participate in a series of meetings and webinars, followed by in-person meetings on the east and west coasts, allowing further exploration of costs, experiences and recommendations for solutions.

Sandia National Laboratories

Modeling Wave Farms with SNL-SWAN for Environmental Prediction

Sandia National Laboratories — Simulating WAves Nearshore (SNL-SWAN) is an open source WEC array simulation tool. The SNL-SWAN code is a modification of the original SWAN open source code that was developed by Delft University of Technology.

The SNL-SWAN code includes the addition of a WEC module, which improves how SWAN accounts for WEC power performance and the effects on the wave field. The development team will give an overview of the SNL-SWAN code, focused on its application to modeling the effects of wave farms on wave environment.
