Projects

DEXADEM is a development project which aims to use an innovative, simple and flexible technology to validate wave energy as a cost-effective, competitive source of electrical power. Activities defined include manufacture of a 5kW model converter – scale 1:5 – procedures and tests setup, deployment, power production, and a final performance assessment. The overall outcome of DEXADEM will be to produce power from a pre-commercial model of a new wave energy converter. The project will provide a detailed assessment of the technology performance in the North Sea wave climate, where it is expected that the electricity generated will have a competitive price as low as 0.06 €/kWh. One of the main results of the project will be the elaboration of important documentation for the design of a full scale model, bringing this technology closer to market. This scale model will also serve as a demonstration platform towards investors and decision makers.

The AQUAGEN project aims to address a major market opportunity by developing a power take-off (PTO) system targeted at marine energy applications, enabling significantly improved reliability and efficiency of around 33%, and with a reduction of 25% in Operation and Maintenance costs, when compared with currently available solutions. Since it is a water-based PTO system, the risks of oil leaks in the ocean will also be fully eliminated. To achieve our objectives, we need to develop new scientific knowledge in: design of innovative system components such as a variable speed generator, an adaptive blade turbine, elastomeric structures and the overall hydraulic system; protective coatings for marine environments; modeling the ageing of elastomeric structures; and wireless controlled monitoring of offshore moving equipment.

H2OCEAN is a project aimed at developing an innovative design for an economically and environmentally sustainable multi-use open-sea platform. Wind and wave power will be harvested and part of the energy will be used for multiple applications on-site, including the conversion of energy into hydrogen that can be stored and shipped to shore as green energy carrier and a multi-trophic aquaculture farm.

Objective: 

The purpose of the BLUE OCEAN ENERGY^® project (BOE) based on the DEXAWAVE converter is to transfer technology from DEXAWAVE ApS to DEXAWAVE Energy Malta for the adaptation of the DEXAWAVE converter from North Sea conditions to Mediterranean conditions. This will be done by constructing a 1:10 scale model of the converters which will be subjected to real Mediterranean sea conditions.  This project will provide the Government of Malta, the Ministry for Resources & Rural Affairs, Enemalta Corporation and the consortium behind the project with sufficient information to justify acceptance, modification or rejection of the proposed project for further financing. If the results of the 1:10 project are positive, the eventual full scale pilot project that shall be deployed in Malta shall provide Malta with Megawatts of clean energy, shall be used as a showcase for the technology and shall put Malta on the forefront of wave energy conversion. Moreover the converters shall be manufactured locally creating jobs, exports and improving GDP.

Objective:

The overall purpose of the FLOAT project is to develop and test a new concept for wave energy floaters, made of Ultra High Performance Fibre Reinforced Concrete (UHPC), as an enabling technology for the establishment of competitive wave energy production. There are a number of transversal barriers are blocking wave power devices in general from reaching a commercial breakthrough as a cost-competitive technology, including factors such as loading capacity, environmental resistance and overall energy price.  The concept behind FLOAT has been established to address these commonly known limitations through the development of an enhanced floating structure, enabling a more sustainable and durable energy production across different wave energy concepts, achieving a lower price of energy produced comparable to prices currently obtained from off shore wind power. Moreover, the concept will enable faster and more flexible production of floaters for wave converters. The flotation device is a key part of converters as it accounts for a considerable share of initial investment, up to 27% depending on the converter, and its maintenance requirements affect the overall power extraction (in downtime production days), with direct implications for the final energy price. Until now, whereas offshore floating structures based on concrete have been frequently used, mainly in the petroleum industry, the use of UHPC has been reserved for on-shore building construction works and engineering projects. The promise of combining the inherent features of both technologies with the specific requirements of wave converters, however, is far from straightforward and requires the overcoming of important technological barriers, which can be summarised as maximizing loading capacity while maintaining the system’s flexibility and mechanical resistance.
