What it is
CorPower Ocean is a Swedish wave energy company that has deployed the C4, a commercial-scale wave energy converter, off the coast of Aguçadoura, Portugal. The device uses a heaving buoy connected to a power take-off system that converts wave motion into electricity. The design incorporates 'phase control' technology inspired by the pumping principle of the human heart, amplifying energy capture by timing the device's response to incoming waves. A C5 array deployment is planned for 2026.
Why we picked this
Wave energy has been 'almost ready' for decades, but CorPower may be the company that finally delivers. Their C4 is the first full-scale wave energy converter to demonstrate sustained grid-connected operation in open ocean conditions. The location choice (Portugal's Atlantic coast) is significant: it is one of the most energetic wave climates in Europe, proving the technology works where conditions are real, not just in test tanks. If the C5 array performs as projected, wave energy costs could reach parity with offshore wind within a decade.
Key takeaways
- Ocean waves carry an estimated 2 TW of energy globally, roughly double current worldwide electricity consumption, making them a massive untapped resource.
- CorPower's phase control technology increases energy capture by 300% compared to passive buoy systems, making wave energy economically competitive for the first time.
- The planned C5 array off Portugal will be the world's first commercial-scale wave energy farm, targeting 10 MW capacity with potential expansion to 40 MW.
