For a successful transition to net zero, all sources of renewable energy must be harnessed. Despite recent estimates that wave power could provide up to 30% of the US energy demand, the expansive power of ocean waves remains largely untapped. Wave energy converters (WECs) capture the steady power of waves to produce clean electricity. However, the vast power of the ocean comes with a downside: frequent, extreme weather conditions and storms create waves with enormous impact on any structure they encounter. To survive these aggressive conditions at sea, WECs are typically composed of heavy and expensive steel, making them challenging to operate and maintain, and ultimately limiting the capacity of WECs to significantly contribute to global energy supply.

CalWave, a spin-out from UC Berkeley, has overcome this fundamental structural challenge by designing WECs that function submerged several metres beneath the ocean surface. Submersion avoids the harshest conditions at the surface while still capturing the power of the waves via pressure exerted on the devices during wave motion. Sheltered from the worst impact, CalWave’s proprietary WEC technology (called xWave™) is composed of lightweight and durable materials, and can autonomously reposition its mechanical components relative to wave size or temporarily shut down during the strongest surges. This combination of features makes xWave™ devices an efficient, cost-effective, and scalable way to capture ocean wave power.

The Biden administration’s Infrastructure Investment and Jobs Act included commitments to invest in “water power projects” and a growing number of coastal states, such as California, have committed to transitioning to 100% clean energy. Having already secured $11 million in development contracts with the US Department for Energy, the outlook is positive for CalWave’s aims to deploy it’s xWave™ technology at utility scale.

  • First long-duration, at-sea technology demo is expected to complete in February.
  • Prepare to install the first commercial-scale, utility grid-connected wave energy test site rated for 20 MW in the USA.

Public or investor-owned electricity providers looking to add predictable and consistent renewable energy capacity to their supply portfolio, particularly in municipalities with unsheltered coastline (such as in the Americas, Australia, Portugal, parts of Scandinavia, South Africa, and the United Kingdom and Ireland) or small island nations (such as those in the Pacific or Indian Ocean, or Caribbean Sea).
