BLUERISE: OCEAN THERMAL ENERGY RESOURCE ANALYSIS

•

U S E CAS E OVERVI EW

Covering seventy percent of our globe, the oceans are the world largest solar collectors. This solar energy is captured as heat in the upper layers of the oceans.

From the natural temperature difference that exists between the upper and deep layers of the ocean, energy can be extracted. This is called Ocean Thermal Energy Conversion (OTEC) and is in particular of interest in the tropics where it can be instrumental in helping islands and coastal regions in achieving a sustainable future. It is considered among the biggest renewable energy sources.

Using the ocean database of Copernicus Marine Service, Bluerise in collaboration with TU Delft, has evaluated the year round and ten year average ocean characteristics in the Caribbean analyzing the ocean currents, density and temperature profiles over depth. Particular attention was spent on ocean upwelling and seasonal fluctuations.

Bluerise has developed a model, using the data from the Copernicus Marine Service, to analyze oceanographic features such as natural ocean current patterns and their variability relevant for OTEC. This enables a quick assessment of the feasibility of OTEC locations.

Ocean Thermal Energy Conversion is a renewable electricity source that uses the natural temperature difference in tropical oceans between the surface water and deep water.

The technology can transform a temperature difference of 20 °C or more into clean, reliable, and predictable base load electricity.

Tropical regions, with population centers near the coast, have ideal conditions to deploy OTEC technology to fully meet their rapidly growing energy needs. Although tropical regions currently account for less than 30% of the current global energy demand, the tropics will become the most significant energy market within the next 20 years.

ESTIMATING WAVE ENERGY RESOURCES IN THE NORTH AEGEAN ARCHIPELAGO

S E CAS E • UOVERVI EW

North Aegean Sea is a relatively rich region for wave energy resource. Although average wave heights ranges in low levels, wind regimes and Aegean geomorphology create frequent waves. On a seasonal basis, the maximum mean wave power occur in winter. Local winds from the North West can make a significant contribution to renewable wave energy production during the summer season.

The scope of the present study is first to identify feasible locations to deploy potential Wave Energy Farms in the North Aegean Sea and then to propose for sustainable water and energy solutions to remote island communities. A method of Multiple-Criteria Decision Analysis (MCDA) was developed using Geographic Information System (GIS) tools. Handling multiple conflicting criteria, the area was designed taking into consideration protected areas, military exercising areas, marine routes etc.. The Copernicus Marine Service wave model in the Mediterranean Sea was used to get an estimation of the wave energy. Results showed that the Skyros island is the most suitable island for the development of a wave energy farm.

All islands in the North Aegean Archipelago face water and energy related issues due to limited sources and obsolete infrastructure. Problems are more intensive during the summer mass tourism that increases population up to 700%.

Import of fossil fuels and water from mainland results into increased costs and management problems. Islands obtain their electricity primarily from diesel generators, providing five time more expensive electricity than on mainland. In the case of water, the resources are quite restricted and expensive. Overexploitation of groundwater resources, through illegal boreholes, causes coastal erosion and soil salinization.

Attention has been raised on the topic of underwater noise and its effects on marine life . Yet, the effects of underwater noise are not fully understood. Some underwater noise can be heard by marine life over hundreds of kilometers. Sources of energy include (but is not limited to: 1) Shipping, 2) Oil&Gaz exploration sonar systems, 3) Construction of offshore Oil&Gaz platforms and wind farms, 4) Dredging for shipping lanes, sand mining and for laying pipes and cables, 5) Coastal developments, 6) Operation of offshore platforms.

To date, there is no global solution providing a first level of information for ocean renewable energy site assessments for tidal energy devices (tidal current speed, tidal elevation, tidal power).

NOVELTIS has developed a unique solution to provide this information: TidEA, Tidal Energy Assessment.

TidEA is a free of charge decision-making tool to identify the most suitable sites for the development of tidal energy and also to characterize in detail the resource of the various sites of interest through the provision of relevant indicators calculated by NOVELTIS teams and validated using products (in situ data, elevation data) provided by the Copernicus Marine Environment Monitoring Service (CMEMS, marine.copernicus.eu). TiDEA lists all the worldwide coastal regions and offers data up to 100 meters deep. For each selected site, you will find the maximum current speeds, the power density and the indicators of occurrence of some specific speed thresholds.

TidEA is used by different types of end-users : NAVAL GROUP and SABELLA for the tidal energy project development and KRAKEN SUBSEA for their business development.

It is particularly fitted to islands in the tropical belt where air conditioning is needed and where a vast reservoir of cold oceanic water is available close by. Deep cold sea water is pumped to the surface and passes through a heat exchange system to cool down the air conditioning network. The pumped water is finally released back into the ocean.

AHPA, Asset Health and Probabilistic Analyses, focuses on probability analyses of fractures and strains on offshore structures.

AHPA gives answers to the questions: How can we be sure that offshore structures are sufficiently safe?

How can we ensure that no accidents occur?

Experience data of where, when and why fatigue cracks occur have been systematically collected for Jacket structures and for Semi-submersibles.

Such fatigue cracks are linked to the strains that offshore structures are exposed to due to harsh weather conditions in the North Sea. Of particular interest is the accumulated impact of wave forces, but also the importance of forecasting wave e.g. wave swell in periods of important marine procedures where the swell frequency is close to the resonance frequency of a structure. This wave information can be derived from Copernicus Marine Service.

For example, the ship heave motion is of serious concern during marine operations. Combined wind sea and swell system from different directions may result in rapid changes in the heave amplitude. CMEMS wave height combined with period is used to predict the 3-dimensional motion of floating bodies.

EFI TS • BEN FOR U SER

A long period of wind observations is important to compute the forces that a structure has been exposed to through that period of time and to model the expected remaining lifetime

A harsh ocean environment with strong winds and waves over decades of use causes significant wear and tear on offshore structures. The angle from which waves hit a platform, and the wave height are important factors, but in addition the wave frequency is an important factor due to the resonance frequency of the structure itself. If a wave system with high energy at a certain frequency hits a structure such as a platform or a ship, it can be extremely dangerous to perform operations.

Wave forecasts from the CMEMS North West Shelf model, including significant wave height, wave period, wave direction, wave energy spectra are used in this application.
