IEA–OES Cost of Energy Assessment

The aim of this project is to provide the Ocean Energy Systems (OES) of the International Energy Agency (IEA) with an authoritative view on what cost reductions are feasible at a global level regarding wave, tidal and OTEC systems.

The assessment of the Levelised Cost of Energy (LCOE) for ocean energy devices represents a critical element of understanding in the development of ocean energy array projects.

Smart Grids: Capacity Credit of Wave and Solar PV

The aim of this project is to determine how new renewable energies can be included in the electricity system and in the operational planning of the system as a substitute for conventional base-load and intermediate-load electricity generation.

Provided that the capacity credit is the amount of thermal capacity that would be displaced by a variable renewable energy portfolio, it is the purpose of the project to find the capacity credit for three scenarios including wind, wave and solar PV.

The results of the project can ultimately lead towards an improvement of existing rules and methods of system planning and system operation.

PhD – Towards the commercialisation of wave energy converters


PhD Aalborg University

“Technical and non-technical issues towards the commercialisation of wave energy converters”.

The thesis elaborates on the necessary steps and on the different difficulties that appear during the development of a wave energy converter. It focuses on seven key areas which appear when a wave energy converter is going through the initial sea trials. All these subjects are of relevance to successfully reach the commercialisation of wave energy converters and need attention from the sector as such, not least from device developers.

The Wavetrain2 Project continues with the research carried on by the previous project Wavetrain.

Wavetrain2 is a multinational Initial Training Network (ITN) funded under the FP7-People program, in order to face the wide range of challenges that industrial-scale wave energy implementation faces in the near future, focusing on technical issues, from hydrodynamic and PTO (Power Take-Off) design, to instrumentation issues and energy storage and cost reduction show to be critical for successful deployment.

Wave Dragon is a large offshore wave energy converter of the over-topping type; a floating hydro-electric dam and represents state of the art technology within the field of wave energy converters. The heart of the unit is a large floating reservoir. Two reflector wings concentrate the power of oncoming waves, which  pass up a curved ramp and into the reservoir. The water returns back to sea through a battery of low-head turbines.

WavePlam Project

While being a research engineer at SPOK ApS – an engineering firm in marine energy projects – Julia participated in the WavePlam project.

The Waveplam project (Wave Energy Planning and Marketing) was funded in 2008 by the European Commission, in order to look into the non-technical barriers hindering the development of wave energy and to develope recommended practices to mitigate them.

INORE seeks to advance the progress of offshore energy by development of the knowledge and skills of those just starting out in the field. To this end, we hold symposia where INOREans can present their research to the rest of the community and hear about the findings and experiences of those who have already been working in offshore renewables for some time. INOREans are primarily Ph.D. and post-doctoral researchers, but we welcome people at a similar level researching or developing in an industrial context, or for a government agency or NGO.
