Dear friends,

On behalf of the U.S. Department of Energy’s (DOE) Water Power Technologies Office (WPTO), I am pleased to present our 2020-2021 Accomplishments Report. This report highlights numerous achievements and results from WPTO-supported research across our Hydropower and Marine Energy programs, including new tools and resources for project developers, numerous in-water deployments of emerging technologies, and innovative science, technology, engineering, and math outreach efforts.

This vital work took place across the country—in DOE national laboratories, on university campuses, in rivers and along coastlines, and in remote villages and communities. Collectively, these efforts are helping our country transition to a clean energy economy while supporting the resilience of communities already experiencing the effects of climate change. Throughout the year, our partners maintained an unwavering commitment to these projects and many others. Our clean energy future can only be realized with the help of people like you, so thank you—to the engineers, students, scientists, community organizations, and countless others—for your hard work.

I hope you enjoy learning more about these projects and are inspired by our opportunities to transform our energy systems. I am also looking forward to what we can achieve over the next year, which includes holding our next WPTO virtual Peer Review in summer 2022 to gather feedback on the past and future direction of the office. This report represents only a fraction of the work our office supports nationwide, and so I encourage you to stay up to date on WPTO’s work and our upcoming events throughout the year by signing up for our Water Wire, Hydro Headlines, and Water Column newsletters. If you have questions about WPTO’s work or the projects featured in this report, please do not hesitate to contact us via email.
