Within the framework of the project consortium of the companies Primum d.o.o., Matris d.o.o. and Harpoon d.o.o. have developed the innovative solution ELVAL for the generation of electrical energy from waves for the vessels’ own consumption. We have managed to generate usable energy even at very low waves. The solution provides additional electrical energy while sailing and at mooring even at low waves. In addition, the generator also has the option of manual operation. With our solution, it is no longer possible to get into a situation where you would be left completely without energy on the vessel, which happens relatively often, especially on less equipped small vessels and/or with less experienced crew.
