Experience this year’s International Conference on Ocean Energy (ICOE) in a whole new way!

This unique all-virtual experience will bring together international stakeholders, experts and exhibitors from the ocean energy sectors (tidal, wave, ocean currents, ocean thermal gradients) with content and networking opportunities—available from anywhere in the world.

ICOE 2021 is hosted by the National Hydropower Association (NHA), and is supported by the International Energy Agency (IEA) through Ocean Energy Systems (OES).

OES is an intergovernmental group that works on international collaboration for ocean energy in order to accelerate the development of the sector and reduce the costs of these energies. NHA’s Marine Energy Council is the leading trade organization of the U.S. ocean energy industry, providing a united voice for the full spectrum of ocean energy technologies.


ICOE 2021 is working in conjunction with NHA’s Annual Conference Waterpower Week to showcase the close partnership and cooperation of conventional hydropower and ocean energy waterpower technologies. Get ready to experience the benefits of both conferences from anywhere in the world!

The ocean energy industry will come together April 28-30, 2021 to discuss device innovation, new market developments and regulatory frameworks to spur commercialization. In addition to unparalleled opportunities to network and learn from industry leaders from around the world, ICOE 2021 provides a variety of forums for attendees to share advancements in research and technology breakthroughs.

“This event presents a unique and important opportunity to bring global leaders together to share experiences and knowhow, with the collective goal of advancing the industry.”

Tim Ramsey, Program Manager for Marine and Hydrokinetic at the U.S. Department of Energy's Water Power Technologies Office and Delegate to the OES.

The theme for ICOE 2021 is “Energizing a Powerful Blue Economy”. NHA is excited to showcase innovations in ocean energy technology research and development, prepare ocean renewable energy to benefit the larger “Blue Economy” and the electrical grid, and identify research needed to further advance the state of the technology.
