Ocean Buoy Array System

The AOE OBAS

AOE was established to implement the patented Wave Energy Conversion technology called the OBAS. This initial technology has led to a total of six patents for associated technologies. These associated technologies can be viewed as accessories that use the compressed air that the OBAS will generate.

The OBAS is a point-absorber style of wave energy conversion device. It is anchored to the ocean floor using tethers and the motion of ocean waves moves the buoy up to compress air in a specially designed cylinder. One of the key characteristics of the OBAS is that it uses compressed air as the energy storage medium and does not generate electricity in the water, which has been found to be a severe limitation to other wave energy devices due to electrolysis.

Compressed Air Uses

Aquaculture - Closed Containment Fish Pen Oxygenation

Water Desalination - Pneumatic Reverse Osmosis

Wastewater Remediation - Oxygenation

Electricity Generation - Remote grid support and diesel abatement

Technology History

The patented AOE Ocean Buoy Array System generates high volumes of compressed air. After 15 years of development, the AOE OBAS is commercially ready for various applications. AOE has been working with UVIC Pacific Regional Institute for Marine Energy Discovery for the past 10 years, modelling and simulating the operation of the OBAS in various wave conditions. A 3-buoy system has a rated capacity in excess of 100 kW continuous with capacity to generate over 1 GWH or desalinate in excess of 280 million litres of water per year without any fuel costs or negative environmental impacts.

Compressed Air is Clean, Safe and Versatile.

Underwater CAES Integrating Renewables

AOE’s pressure-based Wave Energy Converter (WEC) introduces a breakthrough approach to long-duration energy storage by capturing and storing compressed air underwater in durable subsea bladders. Operating naturally under hydrostatic pressure, the system enables high-pressure air to be stored safely and efficiently for extended periods with minimal energy loss. This stored energy can then be released on demand to generate electricity or supply compressed air directly to commercial and industrial applications, including aquaculture, desalination, and marine operations

Unlike conventional battery systems that face limitations in duration, degradation, and environmental impact, AOE’s underwater compressed air storage offers a scalable, low-maintenance, and environmentally responsible alternative for balancing renewable energy supply and demand. The technology is particularly well suited for remote coastal and offshore environments where reliable energy storage is essential. This technology is a key to diesel abatement.

By combining renewable energy generation with integrated long-duration storage, AOE’s system addresses one of the most significant barriers to widespread renewable adoption: intermittency. The ability to store excess energy and dispatch it when required creates a dependable, flexible energy solution that complements wind, solar, tidal, and wave power systems. This innovation represents a critical advancement toward resilient, fully integrated renewable energy infrastructure and a more sustainable global energy future.
