The efficiency of a pioneering device in the European Union (EU) capable of intelligently producing desalination water or electric power from the waves will be tested at a test bench on the Canary Islands Ocean Platform (Plocan), in Gran Canaria.

The director of the Plocan, José Joaquín Hernández Brito, has emphasized that devices like this allow "to generate energy in island systems in a cheap, fast and efficient way".

Generation of desalted water and energy from waves

This project, which could be marketed in one or two years, is funded by the EU and developed in Astilleros Canarios, based in the Port of La Luz and Las Palmas, a business consortium formed by the entities Vryhof Anchors (Netherlands), Fiellberg (Finland), Mediterranean Energy (Italy) and Wavepiston (Denmark).

Hernández Brito has explained that he is able to supply power to devices placed in the marine environment or to devices connected to the grid, depending on the configuration of which he is equipped,

He stressed that "the important thing is that these tests can be done in the Canary Islands because, in this way, we will be able to optimize this technology for its application and commercial deployment, both here and in the rest of the world".

"There is a huge commercial interest in anything that is energy production. The race or challenge is to generate it at a competitive price compared to others of renewable production, such as wind or solar production, although we will need an energy mix of all of them to be able to stabilize the network, especially in island and isolated systems such as the canary," he said.


Pumping seawater


In the opinion of Hernández Brito, the objective of the Canary Islands in this field is "to attract companies and talent so as not to have to buy this technology, but to be produced here", which will contribute to "the creation of this ecosystem of innovation, which is the one that will diversify the economy and generate employment and activity for recovery after covid-19".

For the director of the Canarian Agency for Research, Innovation and Information Society, Carlos Navarro, the technology tested in the Plocan has "very good development in the Canary Islands, where you could get quite a lot of profit, for example in El Hierro, to complement other energy systems".

Noelia Pericón, head in Gran Canaria of the Danish company Wavepiston, integrated into the business consortium that promotes this project, has explained that each of the devices that are tested on this island consists of 24 rows of plates, which are responsible for pumping the sea water with only two anchor points, where its innovation lies.

At 10 percent of its potential, which is the degree to which it is being tested, each line of 24 plates is able to produce 150 kilowatts per hour, which in Denmark, where the energy consumption is much higher than in the Canary Islands, allows to supply 150 houses.

It is also capable of producing 28,000 cubic meters of desalted water per year, a potential that, like that relating to electricity generation, will be 10 times higher when these devices are taken to their total efficiency, said Pericon.
