TRITON SYSTEMS, INC. — Department of Energy SBIR Phase I: 18a

Description

Due to increased pressure from climate change and global energy insecurity, there has been a surge in demand for renewable energy. One potential market has been severely underutilized: marine renewable energy. Buoy mounted LiDAR systems are being used to understand site-specific physical and environmental responses to renewable energy development, which is critical to reducing time and costs associated with planning, developing, and permitting. These LiDAR buoys have significant power requirements that are difficult to meet with on-board solar and wind sources. Triton is addressing this problem by developing a point-absorber type wave energy converter that can be integrated with existing LiDAR buoy systems. It uses an oscillating water column effect caused by buoy heave motion to drive an electrical generator. A specialized control algorithm will be used to maximize power output from irregular ocean wave input. In Phase I, we will demonstrate a concept for a wave energy converter to provide power for LiDAR buoys by: Interfacing with end users and LiDAR buoy manufacturers to develop a design matrix for needs and specifications. Develop mechanical, electrical, and control aspects of the wave energy converter that addresses these specific needs to maintain reliability and measurement fidelity. Test a scale model of the design in a wave tank to evaluate mathematical models, simulations, and design concepts. In Phase II, the design will be improved and tested at full scale in the ocean environment. In addition to enabling increased performance and reliability for LiDAR buoys, variations of the proposed WEC can be used to provide power for other Bule Economy uses including ocean observing buoys, navigational buoys, create UUV recharging nodes, offshore aquaculture, and other marine applications at various scales.
