The wave energy converter inspired by the human heart

Heart specialist Dr Stig Lundbäck was inspired by the pumping of the human heart to co-found Swedish wave energy company CorPower Ocean in 2009.

Through years of hydrodynamic research, the company developed ‘CorPack’ - a gigantic buoy made from durable, lightweight materials that converts the movement of waves into clean and stable electricity.

Similar to the heart’s use of hydraulic pressure to pump blood in one direction, CorPack works by applying tension on itself to pull the buoy down, while the waves push it up. The wave motion is turned into rotation, which is then converted into electricity by generators.

The wave energy converter’s mechanism enables a large amount of energy to be harvested using a relatively small and low-cost device, a CorPower Ocean spokesperson explains.

They say the converter is able to deliver more than five times as much electricity per tonne of equipment compared with previous state-of-the-art wave energy.

This heart-inspired buoy is harnessing wave power in Portugal

European countries with strong Atlantic swells like Spain, France and Ireland have the most wave energy potential.

First onshore wave energy project in the U.S. launches in Los Angeles

In a milestone for U.S. wave energy, officials with Eco Wave Power and AltaSea unveiled a pilot project Tuesday at the Port of Los Angeles.

Excerpt from this LA Times story:

Along a rocky wharf at the Port of Los Angeles on Tuesday, seven blue steel structures bobbed in the gentle wake of a Catalina Island ferry. The bouncing floaters marked a moment for clean energy — the first onshore wave power project in the country.

The floaters belong to Eco Wave Power, a Swedish company behind the pilot project located at AltaSea, a nonprofit ocean institute at the port. They harness the natural rise and fall of the ocean to create clean electricity 24 hours a day.

The pilot project can generate up to a modest 100 kilowatts of power — enough for about 100 homes — but company officials said the ultimate goal is to install steel floaters along the port’s 8-mile breakwater to generate about 60 megawatts of power, or enough for about 60,000 homes.

Such an achievement could be replicated along other parts of the U.S. coastline, according to Inna Braverman, Eco Wave Power’s co-founder and chief executive. She noted that the U.S. Energy Information Administration estimates that wave power has the potential to provide more than 60% of the country’s energy needs.

The technology uses the bobbing floaters to compress pistons, which push hydraulic fluid into storage tanks located nearby on land. As the pressure increases inside the tanks, it spins a motor, which turns a generator that makes clean electricity.

This is different from wave technology offshore, which can be more expensive to install, harder to repair and more difficult to connect to a grid because it’s farther from land, Braverman said. Capturing the energy at the shore enables Eco Wave Power to keep the “expensive parts” on dry land and avoid disturbing the seabed or marine environment.

And unlike other renewables such as wind and solar power, which cannot produce electricity around the clock unless accompanied by batteries, wave energy is 24/7.

How Waves Could Quietly Overtake Solar & Wind. Every crashing wave delivers a pulse of power. Add them all up, and the ocean carries more energy than the roughly 30,000 TWh of electricity generated globally in 2023. But for decades, wave power has been a sea of broken dreams. But in 2023, buoys from a Swedish company called CorPower survived record-breaking 60-foot waves — and kept sending clean power to the grid. With costs plunging and the first full wave farms on the horizon, a decades-old dream might finally be about to break through. So the question is: Is wave energy finally ready for prime time — or will it be just another shipwreck in the history of clean power?
