Wave Energy Generation in Brazil: A Georeferenced Oscillating Water Column Inventory

Seas and oceans offer great potential as a widely available source of clean renewable energy near high consumption centers. This is valuable option in the transition matrix decarbonization. Wave an oscillating water column (OWC) device stand out types ocean with most potential. An onshore OWC requires locations rocky outcrops steeper slopes needs to be physically installed has lower dissipation due friction seabed. However, Brazil approximately 7490 km coastlines, various shoreline geometries geomorphologies, some which are very suitable for implementation. Some authors have estimated that Brazilian coast total 114 GW, distributed between wave tidal energy, possibility contributing global decarbonization efforts. study aimed identify quantify implementing farms equipped OWC. For this, prospect was carried using georeferencing software QGIS, resulting georeferenced map dataset 319 locations, determining power capacity exploitation 9.84 GW 83,689 GWh/year ten seventeen coastal states. corresponds twice state Rio de Janeiro, population 17.5 million people. If same amount gas-fired thermal generation were consumed, use would reduce emissions by 44.52 tons CO2 annually. result suggests should included future studies on expansion electric systems accelerating factor transition.
