Product description

The CorPower Wave Energy Converter (WEC) is a cutting-edge solution designed to harness the power of ocean waves and convert it into clean electricity. The C4 Commercial-Scale Device features innovative technology that allows for efficient energy capture and high durability, making it a sustainable choice for clean energy generation.

At the core of the C4 device is the WaveSpring mechanism, which optimizes energy capture in regular wave conditions and can be detuned during storms to enhance durability. This, combined with an advanced phase-control system, ensures that the device can adapt to varying wave conditions while maintaining optimal performance.

The buoyant 9 m-diameter, 19 m-tall device is anchored to the seabed using the UMACK anchoring system and utilizes a gearbox-based power take-off to generate up to 300–350 kW of electricity. The C4 unit has already demonstrated its capabilities by exporting electricity to the Portuguese grid at Aguçadoura, showcasing its resilience in extreme wave conditions.

Furthermore, the modular design of the CorPower WEC allows for scalability into multi-unit arrays, known as CorPacks, providing a flexible and customizable solution for different energy needs. This technology offers a cost-effective and bankable option for wave energy generation, with the potential to capture up to five times more energy per tonne than other wave technologies.

By combining efficiency, durability, and scalability, the CorPower WEC is paving the way for sustainable energy generation and grid stability on a global scale.

About the Company

CorPower Ocean is a Swedish wave energy technology company dedicated to delivering high-efficiency, resilient wave energy converters (WECs) that transform ocean waves into clean, renewable electricity. Inspired by the human heart, their patented “WaveSpring” technology allows devices to adapt to changing wave conditions—optimizing power capture in calm seas and detuning in storms to ensure survivability. Since its founding in 2012, CorPower has advanced through multiple development stages, successfully deploying the commercial-scale C4 WEC off Portugal in 2023. With headquarters in Stockholm and offices in Norway, Portugal, and Scotland, they partner with utilities, developers, and governments to integrate wave energy into the renewable mix. Their goal is to enable 24/7 carbon-free electricity, support grid stability, and drive the transition to a sustainable, low-carbon future.
