We would like to introduce you Arrecife Energy Systems, they capture the wave’s power and transform it into electricity.

The Arrecife Project was born thanks to the research of the PhD Professor José Javier Doria in the field of fluid mechanics for more than 25 years.

What began as a study, finally became a long research that has had great results in other fields. Prof. Doria observed that the small living corals occupy vast expanses, forming a reef capable of absorbing much of the energy of the waves in an efficient way. This led to the idea of creating serially placed direct-action turbines, composed of many blades that simulate a coral reef.

Key Facts:

• First operating system through turbines.
• Obtains energy from waves, currents and tidal flows.
• It is a completely free source of energy. As long as we have waves we can capture their energy
• According to estimations, the benefits coming from the use of wave energy can be way higher than the ones derived from wind and sun.
• Waves concentrate a greater power compared to other renewable energy sources. Also, their power density is higher than the one coming from wind.

The problem

Fossil fuel, biomass, and waste burning power plants
In the United States, about 67% of total electricity generation in 2016 was produced from: fossil fuels (coal, natural gas, and petroleum), materials that come from plants (biomass), and municipal and industrial wastes.

Emissions that result from combustion of these fuels include:

• Carbon dioxide (CO2)
• Carbon monoxide (CO)
• Sulfur dioxide (SO2)
• Nitrogen oxides (NOx)
• Particulate matter (PM)
• Heavy metals such as mercury

Nearly all combustion byproducts have negative effects on the environment and human health:

• CO2 is a greenhouse gas, and it contributes to the greenhouse effect.
• SO2 causes acid rain, which is harmful to plants and to animals that live in water. SO2 also worsens respiratory illnesses and heart diseases, particularly in children and the elderly.

The Solution

ARRECIFE´S TECHNOLOGY, aims to simulate the natural behaviour of a coral reef, an ecosystem that functions as a natural barrier against waves.

Following the example of other successful systems such as hydraulic energy or wind energy, Arrecife works with turbines too. It is provided with cross flow turbines that get activated by the waves. The system opposes the strength of the waves creating resistance and absorbing large part of its energy.

Helping people

The study, entitled “Health and Climate Benefits of Choosing Different Energy Efficiency and Renewable Energy Options“, demonstrates that energy efficiency and renewable energies can have important benefits for both climate and public health. Jonathan Buonocore, an associate researcher at Harvard University’s Center for Health and the Global Environment, added that this research shows that climate benefits and health benefits are on a par with others.

The implementation of wave energy aspires to contribute to the welfare of society, providing clean-energy jobs to millions of people and helping the world becoming a greener, more sustainable place.

Helping the planet

Environmentally friendly: Once the system is manufactured and the wave energy devices are installed, no polluting emissions are produced.

No danger of pollution: There is no risk of polluting the surroundings in case of a disaster, unlike it occurs when using fossil fuel plants.

Minimal visual pollution: Wave energy converters are installed either on the surface of the water or submerged in the water, minimising alterations in the landscape as much as possible.
