Case study feasibility analysis of the Pelamis wave energy convertor in Ireland, Portugal and North America

An overview on green house gas emission characteristics and energy evaluation of ocean energy systems from life cycle assessment and energy accounting studies

“…In fact, these values are mainly influenced from the capability of annual power generation of the device concerned, its life period as well as of the mass and type of inventory materials of the device concerned. It is to be noted that the above stated 750 kW Pelamis if placed in Portugal coast would have produced half the power than that availed (2.5 GWh annually) from its placement in Ireland coast (Dalton et al, 2010 Table 6. Emission of gases from 7 MW Wave Dragon.…”

“…Its life period is reported to be around 20 years (Parker et al, 2007) with annual power generation of 2.5GWh, if placed in Ireland coast (Dalton et al, 2010). Thus its lifetime power production would be 50GWh.…”

Wind-structure interaction simulations of ovalling vibrations in silo groups

“…Applications in other research fields where flow-induced vibrations can be turned into an advantage are e.g. ocean current-driven energy harvesting devices [52,181,190].…”

“…for the optimization of artificial respirators [112,269]. In civil engineering, offshore applications such as flow-induced vibrations of offshore risers [49,75,108,289] and ocean current-driven or wave energy converters [52,181,190] have been considered. The study of wind-induced vibrations finally was for a long time focussed on flutter of long suspension bridges [155,190,267] but is also used to investigate flexible membrane structures in wind flows [27,103,167,284,286] and for aeroelastic studies of wind turbine rotors [37,98].…”

Economic Assessment of Overtopping BReakwater for Energy Conversion (OBREC): A Case Study in Western Australia

“…The reason can be mostly attributed to the high production costs, compared to other renewable energies technologies, as result of the large environmental forces to which WECs are exposed. Several studies have been carried out regarding the economic analysis of these devices, which is one of the main fields of research in marine renewable energy (e.g., [13][14][15][16][17][18][19][20][21][22][23]). Both the social acceptance of a WEC and the economic appeal for investors and utility providers remain heavily dependent on costs vs. payback analysis, that means competitively priced electricity supplies and reliability.…”
