Ocean Power Technologies

American renewable energy company

Ocean Power Technologies (OPT) is a U.S. publicly owned renewable energy company, providing electric power and communications solutions, services and related for remote offshore applications. The company's PowerBuoy wave energy conversion technology is theoretically scalable to hundreds of megawatts and the generated energy from wave power can be supplied to the grid via submarine cables. Several projects were undertaken around the world, but the economic viability of the theoretical concept has been problematic.2 Wikipedia text CC BY-SA 4.0

Products and brands

Range of products

Devices for the Grid-connected utility market, currently the Mark 3 PowerBuoy.

Devices for the Autonomous market requiring lower levels of power for deep-ocean applications such as maritime security and homeland defense, offshore oil and gas operations, aquaculture and oceanographic data sampling. The company’s PowerBuoy in ratings of 2 kilowatt to 40 kilowatt is ideal for these applications, including the LEAP autonomous PowerBuoy sold to the US Navy.

Infrastructure products and services - cable installations, grid interconnection, permitting and site development, including the company’s Undersea Substation Pod product, available to all companies in the marine energy sector.

Undersea Substation Pod - Device for aggregating diverse power generation devices and supplying an interface with onshore power distribution.

Technology

PowerBuoy

The company's primary product is the PowerBuoy wave generation system. It uses a "smart," oceangoing buoy to capture and convert wave energy into low-cost, clean electricity.

Hybrid PowerBuoy

The company's secondary product, the Hybrid PowerBuoy, generates energy independent of wave motion, instead relying on a solar panel array for charging the onboard lithium iron phosphate batteries. Backup power is provided by a liquid propane 1 kW engine.

Subsea Battery

Unlike the energy-generating PowerBuoy and hybrid variant, the Subsea Battery is a fully submersed energy-storage vessel housing lithium-iron phosphate batteries for powering subsea payloads. The batteries supply 132 kWh (nominal capacity) with up to 15 kW peak power delivery.

Undersea Substation Pod (USP)

The USP is an electrical power aggregator from up to ten offshore power generation devices, be they wind, wave power or other, into one common interconnection point for transmission to the onshore power grid.

The USP can likewise be configured to supply onshore power to offshore devices.
