As the first project to promote the development of sustainable infrastructures in the Canary Islands, we have set ourselves the priority of finding solutions for the production of drinking water. To do this, we have defined three fundamental criteria: self-sufficiency, use of renewable energies and economic and technical feasibility that allows us to implement a solution in the shortest possible time.

Among the various proposals that we have studied, Berinthus Technologies' not only meets the above criteria, but also the scalability of its innovative solution makes it viable for small industries (from a clinic to a hotel complex), as well as for large population centers.

Canarias Archipiélago Sostenible has reached an agreement with Berinthus Technologies to implement this solution in the islands. The above, in strict adherence to the ethical pillars on which our association is based: economic and legal transparency of all the agents involved, combined with the ability to assume full management of the solution by the public or private entity that requires it. A strategic resource is not handed over to third parties.


Producing drinking water in coastal and island
and island territories in a sustainable manner

For many islands, drinking water scarcity is a major problem. Droughts, ever-increasing demand from both the local population and the influx of tourists, and declining groundwater levels are among the factors exacerbating the problem.

Island and coastal territories are among the communities most aware of and affected by the challenges posed by climate change. These communities are therefore obliged to rethink their strategies for energy self-sufficiency and the provision of resources such as water in order to address the problem in a sustainable manner. Reducing carbon emissions is an essential part of rethinking these strategies.


Zero CO2 emissions, zero dependence on fossil fuels, zero
fossil fuels, zero investment







Barinthus Technologies has developed a revolutionary solution based on solar energy to provide drinking water to coastal and island territories. no carbon emissions. Thus, in addition to solving the problem of drinking water production for these communities through renewable energies, the innovative solution presented by Barinthus Technologies also solves the important issue of energy self-sufficiency: The import and use of fossil fuels for the production of drinking water is completely renounced.

On the other hand, the implementation of this solution has been designed in such a way that the economic impact for the communities that adopt it is zero in terms of initial investment, and absolutely transparent in terms of the payment of the cost of the drinking water produced: The cost is paid from the moment the drinking water starts to be produced, per cubic metre of water supplied and at an affordable cost given the absence of fossil fuel use.

For a standard production unit, the amount of savings can be calculated as follows:

One production unit produces 350,000 m3 of water per year (taking into account one day per month of maintenance). Over 25 years, this translates into 8,750,000 m3 of water and zero CO² emissions.

Also, reverse osmosis water desalination using fossil fuels is very energy intensive, typically requiring between 3 and 6 KwH per m³ of drinking water produced. An installation producing 1,000 m³ of water per day emits between 1,000 and 2,000 mt (metric tonnes) of CO² per year (depending on the type of fossil fuel to be used). Therefore, the amount of CO² emissions that can be avoided by using the Barinthus Technologies solution is between 30,000 and 50,000 mt over 25 years. If the price of CO² is calculated at 50 euros per tonne of CO² (emission allowances), the implementation of the project over 25 years has a monetary value of emission savings equal to 1,500,000 - 2,500,000 euros. This is not to mention the potential savings in negative externalities in relation to sea level rise.

Transitioning to a sustainable form of drinking water supply in island and coastal communities does not require long lead times or large-scale construction projects.

The Barinthus Technologies solution is fully scalable. Between 500 and 20,000 cubic metres of water can be generated per day per installation, and supply can start in as little as 12 months. It is therefore A solution that allows the volume of drinking water production to be adapted to the needs of the community or industry. In addition, Barinthus Technologies has developed a new technology that guarantees the continuous production of drinking water 24 hours a day.

Barinthus Technologies has developed a system to capture the optimum amount of energy generated to provide maximum availability for the reverse osmosis equipment, ensuring that the system can operate as efficiently as possible, reducing wear and tear on the equipment and keeping the cost of production low. In this way, the absence of moving parts powered by fossil fuels not only avoids carbon emissions (currently reverse osmosis is responsible for 0.5% of all carbon emissions), it also significantly reduces maintenance costs and contributes to mitigating the effects of climate change.
