Testing facilities and capabilities operated and maintained by national laboratories are pivotal in supporting mission needs of the Marine Energy (ME) program of the WPTO and play an important role in the continued advancement of ME technologies. National lab testing facilitates and capabilities must continue to evolve to meet changing programmatic and technical needs of the ME sector. To meet these present and future testing needs, the ME core national labs, the National Renewable Energy Laboratory (NREL), Pacific Northwest National Laboratory (PNNL), and Sandia National Laboratories (SNL), along with support from Oak Ridge National Laboratory (ORNL) and Argonne National Laboratory (ANL), will collaboratively and collectively develop a long term, up to 10 years, national laboratory focused facilities and infrastructure investment strategy. This project will develop a detailed understanding of (1) present and future ME testing needs; (2) existing infrastructure and capabilities across the ME facility network (emphasizing national lab key assets); (3) gaps in testing capabilities and key laboratory infrastructure; and (4) opportunities for new investments and/or leveraging existing capabilities to strategically support WPTO programmatic goals. This project will also develop an analysis framework to evaluate and strategically prioritize ME infrastructure needs relative to new challenges and opportunities.
