The Water Power Technologies Office (WPTO) will host a series of R&D Deep Dive webinars to share updates on tools, analysis, and emerging technologies to advance marine energy as well as next generation hydropower and pumped storage systems.
These webinars will feature WPTO technology managers, National Laboratory research experts, and other partners, and will highlight WPTO's research and development efforts for the hydropower and marine energy industries. These webinars are an opportunity for stakeholders to provide feedback on tool developments, learn about the latest water power research findings, and get trained up on new resources available to support water power technology development. Each webinar presentation will close with a Q&A.
April 16, 10-2 pm ET | Marine Energy Composites & Manufacturing Workshop
Friday, April 16, 2021 | 10-2 pm ET
Join us for the Marine Energy Composites & Manufacturing Workshop April 16 to learn more about composite materials for the marine energy industry. We will share examples of manufacturing processes that are currently being researched and developed. Panel discussions and breakout sessions will examine the challenges and barriers that must be overcome to support large-scale manufacturing processes.
Interested in an overview of WPTO’s announcements, funding programs, and priorities? Attend a future WPTO Semiannual Stakeholder Webinar or view the past recordings.
April 9 | Leveraging the Advantages of Additive Manufacturing to Produce Advanced Composite Structures
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
Interested in working with DOE or its associated national labs? Wondering how to secure federal funding for your research? DOE representatives directing research for hydropower and marine energy will showcase opportunities for working with the DOE, including different research and development, professional development, and career opportunities.
March 31 | Key Industry Trends for U.S. Hydropower: An Overview of the 2021 U.S. Hydropower Market Report
Did you know pumped storage capacity has increased in the U.S. by almost as much as all other types of energy storage combined from 2010 to 2019? Or that FERC relicensing activity is set to more than double in the coming decade? You might also be surprised to learn that most U.S. hydropower capacity increases are not from new developments, but rather increases at existing facilities, new hydropower in conduits and canals, and by powering non-powered dams.
Learn about these findings and other U.S. hydropower trends during DOE's webinar on March 31st. Representatives from Oak Ridge National Laboratory (ORNL) and DOE’s Water Power Technologies Office will walk listeners through key takeaways from the January 2021 edition of the U.S. Hydropower Market Report. Led by ORNL, the report compiles data from public and commercial sources as well as research findings from DOE projects to provide a comprehensive picture of developments in the U.S. hydropower and pumped-storage fleet and industry trends for U.S. and global hydropower.
March 26 | Summary of Marine and Hydrokinetic (MHK) Composites Testing at Montana State University
The Water Power Technologies Office 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 19 | CREVICE CORROSION IN SEAWATER USING CFRP/HYBRID COMPOSITE AS PART OF A NOVEL CREVICE FORMER
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 >>
