Techno-economic assessment of global and regional wave energy resource potentials and profiles in hourly resolution

Climate change is driving the adoption of sustainable energy, with low-cost solar photovoltaics and wind power at the forefront. However, land-constrained regions and islands have a limited onshore renewable energy potential. Wave power may prove useful for such regions, supported by growing literature in the field. This study delves into...

Numerical Calibration of the Mooring System for a Semi-Submersible Floating Wind Turbine Model

Numerical modeling of the floating offshore wind turbine (FOWT) dynamics plays a critical role at the design stage of a floating wind project. Still, there exist challenges for verification of efficient engineering models against experimental results. Recently, an experimental campaign was carried out for a 1:96 downscaled model of the OC4...

Time Domain Modeling of a Point Absorber

The demand for renewable energies is rising due to climate goals and high oil prices. Not only the established renewable sources like wind and solar are interesting to exploit. There is a vast amount of energy stored in the world’s oceans. To harvest this energy, one needs a Wave Energy Converter (WEC). There<br/>are already some prototype WECs...

Effects of onshore and offshore environmental parameters on the leading edge erosion of wind turbine blades: A comparative study

The presence of rain-induced leading edge erosion of wind turbine blades (WTBs) necessitates the development of erosion models. One of the essential parameters for erosion modeling is the relative impact velocity between rain droplets and the rotating blade. Based on this parameter, the erosion damage rate of a WTB is calculated to estimate...

Recent progress in the economics of ocean thermal energy conversion: Critical review and research agenda

Ocean thermal energy conversion (OTEC) is a Renewable Energy Technology (RET) with a global theoretical potential of up to 30 TW. However, OTEC's economic potential is unknown as it is still an immature technology with no commercial plant operating. This paper reviews recent academic and industrial literature since 2005 to provide an overview...

Performance assessment of the Ocean Falls Wave Energy Converter: A solution for electrical power production in the future

There is a growing demand for renewable sources of energy of which wave energy conversion is one. The Ocean Falls is an oscillating water column (OWC) system invented by BAM Infraconsult b.v. This system differs from conventional OWC systems since it includes a connection tube and an adjustable back wall. The OWC system is a resonance system for...

Numerical Modelling of Interconnected Floating Solar Energy Platforms

Land scarcity is increasing and therefore one of the main challenges for renewable energy in the future is ‘physical space’. While renewables need a lot of space compared to conventional energy sources, and the competition for space is already increasing (food production, housing etc.), leading to higher land costs and opposition. Public...

Assessment of Economic Potential of Ocean Thermal Energy Conversion in Indonesia: A Spatial Approach

<b>What are the national and provincial economic potentials of ocean thermal energy conversion in relation to the provincial electricity demand fulfilment in Indonesia?</b> When we are talking about the economic potential of OTEC in Indonesia, we are talking about potential as a result of different possible configurations. On the national level,...

Feasibility Study on Deep Seawater Solutions for Manado: ROTEC

Due to climate change and growing cities, water scarcity is becoming one of the futures biggest problems. On top of that, the population and prosperity of cities around the equator are growing fast. Meaning that the need for electricity, cooling and drinking water will grow fast in the following decades. ROTEC’s vision is that these growing...

Optimal Configuration of Hybrid Renewable Energy Systems for Islands' Energy Transition

The world’s greenhouse gas emissions have steadily increased as a result of the continued use of fossil fuels, causing climate change. Nevertheless, sustainable energy technologies implementation has increased steadily in the last decade as society attempts to transition to a sustainable, zero emission energy system. The consequences of climate...

Optimization of Island Electricity System: Transition to a sustainable electricity supply system on islands through the implementation of a hybrid system including ocean energy technologies

Climate change without adequate countermeasures has become one of humanity's greatest threat. Energy production by means of renewable energy sources is therefore one of the crucial measures that will play a paramount role in reducing the pollutant emissions of fossil fuel dependency. Small islands in particular are an exemplary case of the...
