The ultimate purpose of the project "New material for wave energy sub‐structures” (Funding body: Energiteknologisk Udviklings‐ og Demonstrations Program (EUDP). Area: wave energy and new sustainable materials for marine environment. Leading: Aalborg University Civil and Chemical, Esbjerg (DK). Other Partners: Resen waves (DK), Electrocell (DK), Wave Piston (DK), Case number: 50520010) is to investigate the possibility of producing a construction material under sea water electrolysis from the mineral deposition accumulated over the cathode. As we know from literature (Goreau 2012), mainly three different kinds of materials can be obtained: Aragonite and Brucite and Calcite. Brucite is friable and brittle and we decided to focus on the production of Aragonite in these first investigations, because, given its mechanical properties ((Goreau 2012), carrying loads, hardness…) it is more interesting for the purpose.
