The PNNL-Sequim campus, in Sequim, Washington, houses the only marine research facilities in the Department of Energy complex. The campus is uniquely positioned for marine-based research that is focused on helping the nation achieve energy innovation and maintain robust, secure coasts.

PNNL's pre-permitted testbed in Sequim Bay is an ideal testing location for a variety of technologies—from new energy systems to AI-enabled maritime technologies—that link Sequim Bay through an energetic tidal channel to the Strait of Juan de Fuca in the Puget Sound.

PNNL-Sequim offers:

• Rapid Access to Diverse Marine Environments: Nearby Sequim Bay provides an ideal setting for comprehensive studies across various marine conditions.
• Extensive Marine Laboratory Facilities: Analytical laboratories and shoreside facilities for conducting research from fundamental science to applied R&D applications and national security. 
• Innovative Technology Testing: PNNL partners with developers and end users to accelerate the pace of maritime innovation by rapidly iterating emerging technology into operational readiness, such as harnessing ocean energy to support autonomous systems that provide sensing in coastal systems.
• Coastal and Marine Ecosystem Research: Data and analyses to inform our understanding of marine ecosystems and potential effects of new technologies.

Expertise and Capabilities

PNNL-Sequim research is supported by staff with a variety of expertise from fundamental research in areas such as biogeochemistry and biomass propagation of marine flora, data collection and monitoring, AI-enabled systems and technology advancement, and Earth systems modeling. 

Research at PNNL-Sequim spans algal biofuels, biofouling and biocorrosion, atmospheric and oceanic conditions, energy and microgrid technologies, environmental monitoring, quantification of chemicals in marine systems, coastal risk and hazard prediction and analysis, and national security. A scientific dive team and fleet of research vessels support in-water research and testing.

To defend coastal regions, PNNL-Sequim researchers bring multidisciplinary capabilities to address a broad range of national security challenges.  Our programs emphasize the transformation of data from various environmental media—air, water, sediment, and biota—into actionable intelligence, ensuring effective coastal protection strategies.

At PNNL-Sequim, we are creating an environment where cooperative autonomous systems can thrive in the maritime domain. We're starting with an autonomous surface vessel and an unmanned aerial vehicle.

Future of Sequim

PNNL-Sequim is currently expanding its research capabilities with upgraded infrastructure and new facilities that will enhance the campus’s abilities to facilitate research from bench to bay.
