“…57,98 In the context of water consumption, the large-scale deployment of hydrogen production in combination with expected additional water demand due to climate change, population growth, economic development, and agricultural intensification might result in water scarcity, which is already the case for Crete and Tenerife. 99,100 Such water scarcity assessments should be addressed on a regional level in future work. [101][102][103] Further, technological material improvements-such as increased material efficiency as well as novel and alternative materials and systems [104][105][106] -in PEM electrolyzers could reduce material availability issues associated to the upscaling of hydrogen production with PEM electrolyzers.…”

“…In the 1970s, desalinating 1 m 3 of water required energy consumption of 22 kWh (Latorre Carrión, 2004). Nevertheless, the application of new techniques has nowadays managed to reduce energy consumption to 2 kWh/ m 3 (Naredo, 2007), and reaching values of 1.06 kWh/m 3 at the present time (Gómez-Gotor et al, 2018). Despite this, some authors consider that instead of using desalination as solution to a lack of water (Aguilera-Klink et al, 2000), it would be less costly, in ecological terms, to undertake better management of water demand since "it is cheaper to save 1 m 3 than to produce it".…”

Water status in the Canary Islands related to energy requirements

A review of the methods of obtaining water in the Canary Islands (Spain) is presented, dividing the islands into two groups: the eastern islands and the western islands. This division is due to the different origins of water resources, with western islands using mainly underground sources, while the eastern ones main source is seawater desalination. Water sources define the way in which water is obtained, as well as the energy expenditure to obtain it. In this review, the energy consumption of different methods of drinking water collection is studied, as well as the resources that make up the energy mix in the Canary Islands. In addition, a projection is made for drinking water consumption and energy consumption related to water use in the archipelago up till the year 2035, in order to observe the expected trends in these sectors.

“…The eastern islands, influenced by their proximity to the African continent and their orography, have been pioneers in seawater desalination (García-Rodríguez et al 2016 ). The first seawater desalination plants were built in Lanzarote and Fuerteventura islands in 1964 and 1974, respectively (Gómez-Gotor et al, 2018 ). Desalination plants have been slowly introduced in the rest of the archipelago becoming predominant on the island of Gran Canaria .…”

The Canary Islands have a water culture tied to the exploitation of their groundwater by means of wells and water galleries. However, the growth of tourism, the increase in the local population and the development of agriculture have led to the emergence of new ways of obtaining water, such as the desalination of seawater. The presence of these desalination plants covers the entire archipelago except for the island of La Palma, and sometimes they function as a complement to water needs, while in other cases they are the only source of drinking water available. To study the environmental impact of the production of drinking water through the exploitation of the aquifer and the desalination of seawater, the carbon footprint methodology was used following the guidelines of the GHG Protocol. The result has shown that seawater installations have the largest carbon footprint, mainly due to the high electricity consumption in the islands and the electricity mix of the archipelago which, as it does not rely entirely on renewable energy sources, increases CO2 emissions into the atmosphere due to the production of drinking water in the islands.
