CalWave xNode

CalWave’s xNode is enabling the Ocean Internet of Things by providing power and access to data offshore. Awarded for its game-changing advancements in the world of wave energy converter (WEC) technology, the xNode is a versatile, adaptable, and resilient ocean-observing platform with built-in power generation. It is lightweight and low cost, resilient for storm survivability, and easily stores, ships, and deploys.

The xNode facilitates and improves a range of existing and novel offshore missions. A standard baseline ocean science sensor suite ensures that every mission maximizes data collection and cross-functional interest. The modular scientific payload compartments can be equipped independently and easily configured in the standardized hull. Next to providing access to remote power and data offshore, the xNode stands out through innovative features such as a digital twin, on-board edge computing, and a lightweight, compact size enabled by an inflatable hull.

A standard xNode can provide reliable power at sea for a range of remote offshore consumers. For example, xNode can easily maintain an AUV docking station to increase remote inspection frequency while reducing vessel costs. In the open ocean, the xNode can accommodate any third-party scientific payload, for instance to complement the ARGO fleet of oceanographic profilers, acoustically monitor fish stocks and marine mammals, or measure CO2 above and below the sea surface.

CalWave HydroNode

CalWave HydroNode is a wave-powered energy node enabling the delivery of fresh water to remote coastal communities and providing for a rapidly deployable, easily operated and maintained system for locally generated desalinated water to support disaster relief.
