Marine energy sources like waves, currents, temperature differences, and salinity gradients can be harnessed to contribute to the growing demand for electricity and to power the blue economy. The marine energy industry has faced many technical challenges around deploying devices in the ocean but has made significant progress over the years. To make this learning accessible, Tethys Engineering hosts documents, information, and resources about the technical aspects of marine energy development.

Tethys Engineering Mission
Tethys Engineering aims to advance marine energy research, development, and deployment by improving access to technical information for researchers, regulators, developers, students, educators, and other stakeholders. The collection of documents on Tethys Engineering preserves knowledge as the industry progresses, provides a foundation for synthesis products, and aggregates reliable information in support of artificial intelligence and machine learning.

Tethys Engineering Team
Tethys Engineering is actively curated and maintained by the Pacific Northwest National Laboratory (PNNL) and sponsored by the U.S. Department of Energy Water Power Technologies Office.
Website Development
Launched in 2019, Tethys Engineering is developed using Drupal, an open-source content management software, and draws on years of software and systems development expertise from the PNNL Development Team. Tethys Engineering aims to follow the FAIR (Findable, Accessible, Interoperable, Reusable) and FARR (FAIR, AI Readiness & Reproducibility) guiding principles. Tethys Engineering content is actively added and regularly reviewed, so it remains up to date and accurate. Feedback and suggestions from users are highly encouraged.
Connection to PRIMRE Network
Tethys Engineering is one of seven knowledge hubs within the U.S. Portal and Repository for Information on Marine Renewable Energy (PRIMRE), which hosts additional marine energy data, information, and resources. Content from Tethys Engineering, Tethys, and other knowledge hubs are searchable in the centralized PRIMRE search. Subscribe to the Tethys Blast and PRIMRE Blast newsletters to stay updated.
