HERO’s Mission: Engineering "Video Games" Meet Wave Tank - CleanTechnica

The article discusses the latest developments in the HERO Wave Energy Converter (WEC) project led by the National Renewable Energy Laboratory (NREL), which aims to advance wave energy technology by combining engineering simulations with physical wave tank testing. Since 2024, the team has been improving the HERO WEC’s design to enhance its robustness, reliability, and deployability. Key upgrades include replacing the original wire rope winch line with a polyurethane flat belt and transitioning from an inflatable raft-like outer body to a more rigid, shell-like frame. This redesign addresses the limitations of the initial compact design, which was constrained by shipping size requirements and suitable only for short deployments, by enabling the device to better withstand harsh ocean conditions for longer periods. The HERO WEC operates by pumping seawater through an onshore reverse osmosis system to produce fresh water, using either hydraulic or electrical configurations. To improve maintenance and survivability, power system components have been relocated to the top of the float. Before finalizing these changes,
