NNMREC Open Data Project

awec Open Data is here! nnmrec.oregonstate.edu/open-data The US Northwest National Marine Renewable Energy Center is hosting data from physical tests for the marine renewable energy research community. Sharing experimental data is a great way to increase the impact of your research and gain wider recognition for your work. Already there are data sets from Autonomous Wave Energy Converter tests in the OH Hinsdale Wave Lab at Oregon State University and from a University of Washington Micropower Tidal Turbine. Bret Bosma, the project’s founder said this: “The motivation for the site is to allow researchers and developers to be able to share their data to foster collaborations and advance the industry.” Great idea Bret!

Nemoh – Open source BEM

Ladies and Gentleman, the moment you all have been waiting for is here – L’École Centrale De Nantes has released an open source boundary-element method (BEM) code called Nemoh for the computation of linear wave forces on and wave fields around floating bodies, i.e. wave energy converters (WECs). The software is being released under Apache License, Version 2.0.

An analysis with BEM software is the required first step in the design and modeling of a WEC. Commercial BEM codes can cost $25,000 and up. The release of a free and modifiable BEM software package can help a great number of small WEC developers and researchers who can’t afford the commercial version, and it has the potential to develop a community of users who are actively engaged in improving it!

Free Wave Energy COE Tool

Open-source offshore renewable energy is really happening. Free tools are being developed, and OpenORE will bring them all together!

feature COE

Aalborg University together with Energinet.dk and Julia F. Chozas Consulting Engineer, have released a freely available online spreadsheet to evaluate the Levelised Cost of Energy (LCOE) for wave energy projects. The open-access tool calculates the LCOE based on the power production of a Wave Energy Converter (WEC) at ten locations. Production data may derive from laboratory testing, numerical modelling or from sea trials. The tool has been developed as a transparent and simple model that evaluates WEC’s economic feasibility in a range of locations, while scaling WEC’s features to the selected site.

You can download the tool from Julia’s website:

SOWFIA Data Management Platform

Besides hosting data, OpenORE will collect open-access databases and open-source software projects on offshore-renewable energy into one well-designed searchable and browsable site. You would be surprised at how many projects exist!

The SOWFIA (Streamlining of Ocean Wave Farm Impact Assessment) Data Management Platform presents a vast amount of environmental and social data collected by the SOWFIA consortium for 6 wave energy test centres across Europe. It is really a fantastic collection of information and the data management platform is well designed, straight-forward to use, and makes the data very accessible to non-scientists.

Marine Renewable Energy Knowledge Exchange

textlogo

The UK Natural Environment Research Council (NERC) has developed a Marine Renewable Energy Knowledge Exchange Programme that provides a wealth of valuable and well-organized information. On the existing (and ever-developing) programme portal, you will find:

  • An events calendar, which relays information on marine renewable energy events.
  • A funding page that highlights all funding opportunities that could be relevant to people in the sector. When new items are added, alerts will be tweeted, so follow @MREKEP on Twitter. The programme can also directly fund certain small projects and internships.
  • Literature – papers, reports and more. There is a huge library of links – it is searchable and growing! Anyone can submit entries to be added to this collection by e-mailing mrekep@nerc.ac.uk
  • Images – It can be tough to source relevant pictures for work such as web content. The site is working to build up a collection that anyone can use as long as they credit the photographer. Feel free to add to it.
  • Research – There is also the beginning of a database of ongoing research in the field.

The NERC MREKEP portal is really excellent. Take a minute to check out the site:
