Bóia inspirada no coração humano transforma ondas do mar em energia limpa em Portugal

Com 71% da superfície da Terra coberta por oceanos, a energia gerada por suas ondas representa um dos recursos renováveis mais promissores e ainda pouco explorados. Segundo a Agência Internacional de Energia, é necessário que a produção de energia oceânica cresça 33% ao ano até 2050 para que o mundo alcance a meta de emissões líquidas zero. O Painel Intergovernamental sobre Alterações Climáticas…

The CorPower Wave Energy Converter

The Wave Energy Converters (WEC) developed by CorPower Ocean are small and light with low inertia creating the advantage of being energized by a broad range of waves as well as enabling easy mass production and lowering capital expenditure costs. They are also fault tolerant and importantly deliver a predictable electricity output with a distributed electricity generation concept.

In terms of energy output CorPower’s technology offers exceptionally high power density, 5 times higher than competing technologies at less than a third of the cost.

The compact WEC systems are of the point absorber type, with a buoy on the ocean surface absorbing energy from waves. The WEC is located at a depth between the surface and sea bottom where it is protected from rough seas. Force is transferred to the WEC by a buoy tether, and it is moored to the sea bed.

Flexible connection points automatically minimize harmful lateral forces on the WEC.

Our WEC has a unique Power Take-Off (PTO) design that combines the high load capabilities from hydraulics with the efficiency of a direct mechanical drive.

Temporary energy storage is provided by a two-step approach, smoothing the electrical power output compared to the power profile of typical ocean waves and minimizing the cost of electronic components.

The system has been designed for low inertia and high structural efficiency, allowing the use of active phase control to optimize power absorption.

CORPOWER WEC FEATURES

Protection from extreme forces by oscillator design

Robust end of stroke damping by hydraulics

Active phase control by latch technology

Structural efficiency, compactness and low inertia

Good survivability – designed to be fully submerged

Gear technology helps lower cost of wave energy farming

A Swedish company has cracked the challenge of scaling up wave energy, with the help of technology from researchers at KTH Royal Institute of Technology.

CorPower Ocean’s new wave energy system, which uses a gearbox design that KTH researchers helped develop, generates five times more energy per ton of device, at one third of the cost when compared to competing state-of-the art technologies. Energy output is three to four times higher than traditional wave power systems.

The company’s innovation was recently awarded EUR 100,000 at the MIT Building Global Innovators Demo Day.

Wave energy has been held back in part because of the cost of electricity generation. The amount of steel and concrete needed in order to produce each MWh has simply been too great to make it into a profitable business. Even still, the power of waves presents a problem with reliability; and because waves vary greatly in height and timing, it’s difficult to create a conversion system that functions across the full wave spectrum.

Known in the wave energy industry as a point absorber type system, the CorPower converter consists of a buoy that absorbs energy from the waves, plus a drivetrain that converts the buoy’s motion into electricity. The company’s system is based on Swedish cardiologist Stig Lundbäck’ patents, some of which are inspired by his research into heart pumping and control functions.
