Reports

Below is a list of freely downloadable reports produced either within the SuperGen Marine Consortium itself or by other bodies in collaboration with members of the research team. Click the link in the title or the front page image to get a pdf copy of each report. The reports are split into two categories, the first has high level information such as roadmapping documents and the second category contains reports of a more technical nature. These reports span all three phases of the SuperGen project.

The available categories are:

  1. Strategic and Roadmapping Documents
  2. Technical Reports

Strategic and Roadmapping Documents

OES International Vision for Ocean Energy (Version 2)

The OES International Vision for Ocean Energy provides a global perspective of the ocean energy sector. Contained within the document are new goals for installed capacity, carbon saving and jobs creation as a result of ocean energy deployment at an international scale. These goals were developed through consideration of the available resource, technology profiles, technology cost reduction potential, and policy drivers within the future markets for ocean energy. Version 2 was released in October 2012.

ORECCA European Offshore Renewable Energy Roadmap

This document represents for the first time a combined roadmap developed for the offshore wind, wave and tidal stream energy sectors, focussed on the synergies, opportunities and barriers to development that are revealed when the sectors are investigated together in pan-technology and pan-European context.

The principal target audiences of the recommendations set out are policy makers at the EU and Member State level. However, the recommendations and the way forwards set out are also of high importance for other stakeholders to the offshore renewable energy sector.

The roadmap is structured around five key streams which are essential to the development of the offshore renewable energy sector.

UKERC Marine Roadmap

This document is a technology roadmap: it provides a guide for mobilising the wave and tidal energy community in the UK down a deployment pathway towards a target of achieving 2GW installed capacity by 2020.

The roadmap is aimed at technology developers, project developers, policy makers, government bodies, investors (public and private), the supply chain, consultants, and academics, in order to aid coherent progression of the sector.

ETI Marine Energy Technology Roadmap

The ETI, in conjunction with the UK Energy Research Centre, has published a roadmap identifying the key issues faced by the marine energy sector.

This Roadmap, developed in conjunction with UK Energy Research Centre (UKERC), identifies the key technology and deployment issues faced by the marine energy sector in the UK, and provides initial prioritisation of these issues from the perspective of the Energy Technologies Institute (ETI).

The analysis presented in the Roadmap includes target costs and performance for the UK marine energy sector, with timelines for their delivery, based on in-house ETI techno-economic analysis. This, along with the specific technology priority areas also identified in the document, will be used by the ETI to help define future project interventions in the marine energy sector.

Guidance for Numerical Modelling in Wave and Tidal Energy

Numerical modelling within the marine renewable energy community is in its infancy compared to more mature engineering disciplines such as aeronautics. Additionally, established software from other fields is often applied to marine energy challenges. These issues can manifest several difficulties such as conflicts in language and notation (semantics) and deficiencies in the approximations or applications of the models themselves. Numerical modelling has the potential to provide key cost reductions to the marine renewable energy community by replacing expensive experiments and prototypes with cheaper, reliable numerical simulations. Within this document, approximation, development and analysis of numerical models are detailed. Emphasis is placed on appropriateness of approximation, quality assurance of development and the rigour of the verification and validation process in order to ensure that results from numerical models, both developed and applied, are as efficient, reliable and transparent as possible.

Guidance for the Experimental Tank Testing of Wave Energy Converters

Experimental tank testing is a key aspect of wave energy conversion research. The performance of designs can be assessed in an accessible and controlled environment and at a fraction of the cost of sea trials.

There are many different ways to conduct experiments and it is beyond the scope of this document to cover them all. Instead, the author would like to raise readers’ awareness on several key aspects of wave tank testing for wave energy conversion. These have been divided into three categories:

  • Model making: construction techniques, scaling considerations instrumentations.
  • Measurements: wave measurement, measurement of model motions, data processing (mainly focussed on Fourier analysis).
  • Wave generation: deterministic and non-deterministic methods, wave tank calibration and phase locking.

This document is based on tank testing practices that have been developed over the years at the University of Edinburgh. As such it is focused on the use of equipment that has been developed by the University of Edinburgh and Edinburgh Designs Ltd.

An Appraisal of a Range of Fluid Modelling Software

The design of marine energy converters (MECs) eventually requires the calculation of values such as forces and motion amplitudes in order to assess the performance of the device and its suitability for the purpose. The complex nature of the environment within which MECs work, and the consequential complicated mathematical description of it, necessitates the use of computer methods to solve these problems. Many programs have been devised to solve fluid dynamics problems of this nature, some application-specific, others of an extremely general character. Some programs have been produced by research departments mainly for in-house use, others have been developed commercially and are on general sale. There are hundreds of them, so some selection has been unavoidable, though it is hoped that those selected form a representative group.
