This article covers research into rotational speed control for oscillating water column converters (OWC). The primary focus is the improvement of the Wells turbine performance by controlling its rotational speed. In this sense, the proposed control scheme has been implemented based on the NEREIDA MOWC demonstration project, a breakwater wave plant located in the Basque location of Mutriku, using Wells...
After the 2015 United Nations Climate Change Conference (COP21) the interest for clean and renewable energy is high priority in global energy policy. In this sense, the ocean offers a great potential for energy harnessing. However, in the path to commercialization, conversion systems still lack maturity. Oscillating water column (OWC) power plants are among the most promising cost-effective and ecologically...
Climate change is challenging the current worldwide model of power generation. In this sense, European Union is promoting a deep transition collected in the 20-20-20 targets and the 2050 Energy Roadmap. These adjectives must be achieved by developing the use of clean, carbon-free energies, as it is the case of the renewableenergies and in particular of the ocean energy. The main problem with these...
This article covers research into cost reduction pathways for wave energy. The primary focus is the development and test of reliable and controllable power take-off (PTO) technology for oscillating water column converters (OWC). This is highly relevant to the ocean energy challenge. Extensive testing via data of the NEREIDA MOWC demonstration project, a breakwater wave plant located in the Basque...
The European Union is promoting the use of renewable energies as a path to fight global warming. Among them are diverse ocean energies and in particular, Oscillating Water Column (OWC)-based wave energy stands as one of the most promising technologies. An OWC device is basically composed by a capture chamber with a turbo-generator module attached to it. Although the study of the induction power module...
In the current scenario, the consumption of fossil fuels and the energy obtained by means of nuclear fission are questioned due to all the problems they concern. One of the best answers to that issue is the use of renewable energies and, amongst them, Oscillating Water Column (OWC)-based energy converters. These devices transform the mechanical energy of the waves into electrical power by means of...
