The U.S. Department of Energy’s (DOE) Water Power Technologies Office (WPTO) today announced over $16 million in new projects to further hydropower and marine energy research and development. These awards encompass $5.6 million for hydropower projects and $10.5 million for marine energy projects across six national laboratories.
Hydropower accounts for 31.5% of U.S. renewable electricity generation and 6.3% of the country’s total electricity generation. While marine energy is not widely deployed across the country, the total available marine renewable energy in the United States is equivalent to approximately 57% of all U.S. power generation in 2019. Even if only a small portion of this technical resource potential is captured, marine energy technologies would make significant contributions to U.S. energy needs.
These projects will advance hydropower and marine energy technologies and their roles in achieving both national and local clean energy goals.
Researchers at Argonne National Laboratory (Argonne), Idaho National Laboratory (INL), National Renewable Energy Laboratory (NREL), Oak Ridge National Laboratory (ORNL), Pacific Northwest National Laboratory (PNNL), and Sandia National Laboratories (Sandia) will lead these projects. All of the hydropower projects and four of the marine energy projects (under the New Remote Coastal Community Work—Microgrid Application and Environmental Monitoring Campaign topics) are funded through the Bipartisan Infrastructure Law. The remaining marine energy projects are funded through WPTO’s Fiscal Year 2022 appropriations.
The projects announced today include $2.7 million in Marine Energy “Sapling” projects and $1.1 million in Hydropower “Seedlings” projects. WPTO developed the Seedlings and Saplings program to encourage and provide short term funding to new and innovative research ideas in hydropower and marine energy at the DOE national laboratories. Projects start as Seedlings eligible for up to $100,000. Promising Seedling projects are then eligible to become Saplings with funding of $150,000 to $500,000.
Hydropower Lab Call Selections
The 13 hydropower projects cover four topic areas and include the following:
Topic: Fish Passage
SELF-POWERED MODULAR ACOUSTIC TELEMETRY SYSTEM WITH SENSING CAPABILITIES
In this project, PNNL will partner with Pennsylvania State University and industry partners to develop a self-powered, modular acoustic telemetry system that allows for long-term monitoring of fish, like American eel and sturgeon over large distances. This concept seeks to replace batteries, which limit the amount of time a species can be tracked, with a kinetic energy harvesting unit to power the tag with the motion of a fish’s own swimming. This is expected to significantly advance the ability to collect fish movement and migration data relevant to hydropower permitting and evaluations of basin-scale river connectivity to inform fish passage outcomes.
PREDICTING ABSOLUTE STRIKE INJURY RATES OF TURBINE PASSED FISH USING AUTONOMOUS SENSOR FISH
In this project, PNNL and industry partners will develop a set of metrics and a framework to predict the injury and mortality rates of fish passing through turbines using measurements from existing datasets collected using the Sensor Fish device.
