Brazil relies on wave energy as a renewable energy source with new technology

The sea boils without interruption and, only with the sway of its waves and tides, it is possible to generate up to 40 MW (megawatts) of energy per kilometer of coastline when the swell does not exceed one meter in height.

To take advantage of this potential, Eco Solutions has set to work in Brazil, where it will progress towards obtaining energy from sea waves results in reduced costs than those from other renewable energies such as solar or wind power.

The technology that makes this energy consumption possible comes from the Israeli company Eco Wave Power (EWP), which specializes in developing systems to convert ocean waves into energy.

Innovative devices to capture wave energy.

With “ The Wave Clapper ” and “ Power Wing ”, the two devices developed by the company, the main challenges which, historically, have been posed to capture the energy of marine movement are overcome, such as bad performance or the danger that storms represent for teams.

Faced with these problems, the solution of these experts are buoys that capture the energy of waves and tides and that have a shape that does not limit the capture of energy when a wave hits the buoy, but allows it to ‘to be constant. To do this, according to EWP, we realized that it is the buoys that go with the wave, and not the other way around, thus increasing the throughput in terms of kilowatt-hour output.

To ensure the safety of equipment, they are subject to pre-existing structures, such as floating platforms or breakwaters. In addition, to avoid subsidence, control systems have been integrated into the devices responsible for submerging and extracting them to the surface under unfavorable conditions.

In addition to their efficiency, these solutions are ideal for installation in countries like Brazil or others with similar characteristics, as they use low-cost materials, have low maintenance costs and their life expectancy is at least 30 years.

Another aspect for which these systems are particularly applauded is for their ability to overcome one of the classic problems of harnessing ocean waves for power generation: that equipment typically dumped polluting waste into the ocean. water; which makes them unconvincing as a sustainable energy alternative. However, EWP eliminates this risk by installing the work equipment from which this waste usually originates on the ground, which minimizes any risk of contamination of the sea surface by oil and fluids.

The possibilities offered by this proposal are not only viable and as wide as the sea, whose movement could translate in Brazil by an energy production of up to 40 GW (gigawatts), but they offer answers for any low-income country which, with this alternative, could progress towards energy independence and achieve electricity to reach the millions of people who, even today, live without access to electricity. ‘energy.

This is not Brazil’s first experience with wave energy, a few years ago it was experienced in the Port of Pecém with this technology, a pioneer in Latin America.
