Supporting the development of novel wave power technology.

Xodus Group’s specialists screen the environmental impact of Oyster wave power technology and provide economic assessments.

Challenge
Aquamarine Power’s Oyster wave power technology captures energy in nearshore waves and converts it into clean, sustainable electricity. Xodus Group was asked to assist in the preparation of the consent applications for the Oyster 1 prototype wave energy device which was successfully deployed at the European Marine Energy Centre (EMEC) in 2009. Oyster 1 became the world’s largest working hydro-electric wave energy device to generate power to the grid.

Building on this initial work and understanding of the technology, we assisted in site selection and constraints mapping in advance of the world’s first wave and tidal commercial leasing round in the Pentland Firth and Orkney waters. Subsequently, Xodus Group was awarded a contract to provide environmental support to the deployment of the next generation of Oyster projects in Orkney, which involved Environmental and Social Impact Assessment (ESIA) scoping studies and management of the subsequent ESIAs for demonstration scale projects.

Assignment scope

  • Site selection support and constraints mapping
  • Seabed survey design and interpretation
  • Environmental consent applications support for prototype testing
  • Support for Crown Estate lease bids
  • ESIA scoping and development of consultation strategy
  • ESIA survey and study design and implementation
  • Environmental monitoring protocol design and implementation
  • Marine wildlife baseline monitoring
  • Appropriate assessment.

Results
Xodus Group helped Aquamarine Power overcome risks to the project by designing and implementing appropriate monitoring protocols to collect sufficient data for analysing the impact of these novel technologies on the environment. Our local knowledge and existing stakeholder relationships underpinned the support we provided in the development and execution of stakeholder consultation.

Our Integrated Production Modelling (IPM) toolkit was used to calculate the projected revenue stream for a number of cases, providing the basis for high-level economic screening. We created production profiles for each concept and combined them with Capital Expenditure (CAPEX) and Operating Expenditure (OPEX) estimates to deliver high-level economic assessments.
