Bárður Joensen verjir ph.d. á DTU

Hósdagin 20. apríl klokkan 13 føroyska tíð verjir Bárður Joensen ph.d.-ritgerð sína við DTU,  Department of Civil & Mechanical Engineering

Ritgerðin kallast "Wave energy conversion in the Faroe Islands", og Bárður Joensen hevur arbeitt við granskingarverkætlanini á LBF og á DTU, har hann hevur verið innskrivaður til ph.d.-lestur. Eisini hevur hann samstarvað við Náttúruvísindadeildina á Fróðskaparsetrinum.

Talan er um eina vinnu-ph.d.-verkætlan, sum Granskingarráðið hevur stuðlað við fígging frá Minningargrunninum fyri Dánjal Niclasen.

Verjan verður á DTU í Lyngby í bygningi 303A, Auditorium 4 1. Eisini verður verjan stroymd á Zoom, leinki her

Høvuðsvegleiðari hevur verið Harry B. Bingham, professari.

Hjávegleiðarar hava verið Bárdur A. Niclasen, lektari á Náttúruvísidnadeildini, seinni leiðari á Veðurstovu Føroya og Jan Odmarsson, leiðandi verkfrøðingur á LBF.

Í metingarnevndini eru Yanlin Shao, lektari á DTU Construct, Claes Eskilsson, lektari á Aalborg Universitet, Guillaume Ducrozet, lektari á Ecole Centrale de Nantes í Fraklandi og formaður fyri verjuna er Robert Read, seniorgranskari á DTU Construct.

The global energy demand is rapidly increasing and along with the damaging effects from greenhouse gas emissions and climate change, there is a need for transition from fossil fueled energy production to renewable energy production. Wave energy has been deemed one of the more promising renewable energy technologies, with the tremendous amounts of energy stored in ocean waves. As wind- and solar power are at a commercial stage, wave energy is still at a pre-commercial stage and could prove vital in the mix of renewables for energy  production.

This thesis covers some of the important aspects of consideration regarding wave energy conversion installation. The waters around the Faroe Islands are assessed in terms of wave resource characterization i.e., how much energy is stored in the ocean waves around the Faroe Islands. As wave energy is still at a pre-commercial there is not one specific design best suited for power production, as is the case with e.g. the wind turbine. Several of the main working principles of wave energy capture are evaluated in terms of power performance, along with the devices’ suitability in terms of size and wave conditions.

An optimization strategy is implemented in order to improve the energy capture of an existing wave energy working principle, along with potentially driving down the cost of energy. Furthermore, economic feasibility of wave energy conversion devices is assessed for Faroese wave conditions and compared to other locations in the world, along with a comparison to offshore floating wind power.

Results from the thesis show that the waters around the Faroe Islands enclose high amounts of wave energy, and that the Faroe Islands are a suitable location for wave energy conversion  device deployment.
