August 11 | Seeding Water Power Innovation: An R&D Showcase
In 2019, The Water Power Technologies Office established the Seedlings Program to provide smaller funding awards for national lab researchers to explore niche projects and creative ideas in hydropower and marine renewable energy research. In just two years, the pilot funded over 70 R&D projects across six national laboratories with sums up to $100,000 each. These projects have the potential to inform future programmatic competitive solicitations, initiatives, and follow-on projects depending on outcomes. Through project presentations and panel discussions, presenters will share solutions found, failures faced, and lessons learned in their innovative process.
JULY 28 | CONTRIBUTING DATA AND INFORMATION TO PRIMRE
DOE's Water Power Technologies Office recently presented on PRIMRE (Portal and Repository for Information on Marine Renewable Energy). PRIMRE is WPTO’s centralized system for storing, curating, and disseminating data and information for all aspects of marine energy. All data and information generated from WPTO national lab, university, and industry projects will find a home somewhere in PRIMRE. This webinar provided a brief introduction to the PRIMRE universe, and then focused on how you can contribute your data to the various knowledge hubs that make up PRIMRE: MHK Data Repository, Tethys, Tethys Engineering, Marine Energy Software Database, Marine Energy Projects Database, and Telesto. PRIMRE is a collaboration between three US Department of Energy national laboratories: Pacific Northwest National Laboratory, National Renewable Energy Laboratory, and Sandia National Laboratories.

July 8 | 2021 Hydropower RAPID Toolkit Annual Update
NREL provided an overview on the Hydropower Regulatory and Permitting Desktop (RAPID) Toolkit project as well as recent regulatory and technological updates, including newly released tools, data, and publications. Participants asked questions and provided input on how the hydropower community can best utilize the toolkit. Download the slides >>
June 24 | Underwater Observations – Monitoring the Environment around Marine Energy Devices
The Triton Initiative is researching various environmental monitoring technology and methods to understand how different types of stressors caused by marine renewable energy devices can be tested. The research focuses on the known environmental stressors identified in the State of the Science Report produced by PNNL’s OES-E team. The stressors include collision risk, underwater noise, electromagnetic fields, or changes in habitat. The information gleaned from this research will produce a set of recommendations to inform regulators on how to safely permit marine renewable energy devices bringing the nation closer to meeting climate change goals and reducing dependency on fossil fuels.

June 2 | Accelerating Irrigation Modernization
DOE's Water Power Technologies Office is accelerating reinvestment in the nation’s irrigation systems to simultaneously promote farmers’ and rural communities’ economic well-being, generate more renewable energy, advance environmental stewardship, and enable agricultural decarbonization. Idaho National Laboratory and Pacific Northwest National Laboratory have developed a decision support and visualization tool called IrrigationViz to analyze the costs and benefits of modernization.

May 27 | Introducing the New Marine Energy Atlas
NREL and WPTO presented on the recently upgraded Marine Energy Atlas, a data and visualization platform that houses the highest resolution publicly available long-term wave hindcast data set that covers the East Coast, West Coast, Alaska, and Hawaii.
The Marine Energy Atlas is a product of the multi-lab resource characterization project. An interactive mapping tool developed to explore potential for marine energy resources, the atlas depicts and maps wave energy; tidal, ocean, and riverine current resources; as well as ocean thermal resources in the United States. Users can explore several variables in each of these mapped resource types, such as peak wave period, tidal and ocean current speeds, and more, by employing data layers. Download the slides >>
April 16 | Marine Energy Composites & Manufacturing Workshop
WPTO held a workshop on marine energy composites and manufacturing. The Marine Energy Composites & Manufacturing Workshop was a deep dive on composite materials for the marine energy industry. Examples were shared of manufacturing processes that are currently being researched and developed. Panel discussions and breakout sessions examined the challenges and barriers that must be overcome to support large-scale manufacturing processes.
April 9 | Leveraging the Advantages of Additive Manufacturing to Produce Advanced Composite Structures
WPTO held a webinar on “Leveraging the Advantages of Additive Manufacturing to Produce Advanced Composite Structures for Marine Energy Systems.” Many marine energy systems designers and developers are beginning to implement composite materials into the load-bearing structures of their devices, but traditional mold-making costs for composite prototyping are disproportionately high and lead times can be long. Furthermore, established molding techniques for marine energy structures generally require many manufacturing steps, such as secondary bonding and tooling. This webinar explores the possibilities of additively manufactured composite molds and how they can be used to reduce costs and lead times through novel design features and processes for marine energy composite structures.

April 6 | Introduction to Working with the U.S. Department of Energy
WPTO held a webinar for those interested in working with the DOE or its associated national labs. DOE representatives directing research for hydropower and marine energy showcased opportunities for working with the DOE, including different research and development, professional development, and career opportunities.

MARCH 19 | CREVICE CORROSION IN SEAWATER USING CFRP/HYBRID COMPOSITE AS PART OF A NOVEL CREVICE FORMER
WPTO held its second webinar in the WPTO R&D Deep Dive Webinar Series. Professor David Miller gives a summary of marine hydrokinetic energy composites testing at Montana State University (MSU).
The primary structure of MHK energy devices have difficult and challenging environments for which fiber reinforced plastics are often considered. For cost benefits, glass fiber reinforced plastics (GFRP) are the most prevalent system under consideration. MSU and Sandia National Laboratory have performed research into the moisture effects on the stiffness, strength, and damage of GFRPs for many years. This talk presents a summary of a portion of this effort and also provides references to the thesis and conferences that contain the detailed information. The results include models of moisture absorption, effects of stress on moisture uptake, effects of moisture on damage modes and development, laminate stacking order effects, and culminates with moisture uptake effects on a large sample of industry collected coupons.

March 26 | Summary of Marine and Hydrokinetic (MHK) Composites Testing at Montana State University
WPTO held its first webinar in the WPTO R&D Deep Dive Webinar Series. Francisco Presuel-Moreno, professor in the ocean and mechanical engineering department at Florida Atlantic University, presented on crevice corrosion in seawater using CFRP/hybrid composite as part of a novel crevice former.
Marine hydrokinetic (MHK) devices for renewable energy power generation are fully or partially immersed in seawater while in service. MHK devices sometimes are made of composites and a variety of alloys. The composite type used is sometimes carbon fiber reinforced polymer (CFRP) composites, other times fiber glass reinforced polymer (GFRP) composites are used. In some cases, the composites are fastened using metallic hardware. The fastened composites can cause tight occluded regions that later could become crevice corrosion on the fastened metal regardless of the type of composite. A modified crevice former was used to investigate crevice corrosion for fastened samples immersed in seawater using CFRP/hybrid composite plates. Three alloys were investigated: 316 stainless steel, Monel and Titanium alloy. Selected samples were removed for visual examination and dis-assembled after more than 270 days (up to 810 days). Crevice corrosion and pitting corrosion was found on the stainless steel and Monel hardware, and corrosion extent increased with time. Download the slides >>
