    Lewis Wave Power Limited 40MW Oyster Wave Array North West Coast, Isle of Lewis Environmental Statement Volume 1: Non-Technical Summary March 2012 40MW Lewis Wave Array Environmental Statement 1. NON-TECHNICAL SUMMARY 1.1 Introduction This document provides a Non-Technical Summary (NTS) of the Environmental Statement (ES) produced in support of the consent application process for the North West Lewis Wave Array, hereafter known as the development. The ES is the formal report of an Environmental Impact Assessment (EIA) undertaken by Lewis Wave Power Limited (hereafter known as Lewis Wave Power) into the potential impacts of the construction, operation and eventual decommissioning of the development. 1.2 Lewis Wave Power Limited Lewis Wave Power is a wholly owned subsidiary of Edinburgh based Aquamarine Power Limited, the technology developer of the Oyster wave power technology, which captures energy from near shore waves and converts it into clean sustainable electricity. Aquamarine Power installed the first full scale Oyster wave energy convertor (WEC) at the European Marine Energy Centre (EMEC) in Orkney, which began producing power to the National Grid for the first time in November 2009. That device has withstood two winters in the harsh Atlantic waters off the coast of Orkney in northern Scotland. Aquamarine Power recently installed the first of three next-generation devices also at EMEC which will form the first wave array of its type anywhere in the world. 1.3 Project details The wave array development will have the capacity to provide 40 Megawatts (MW), enough energy to power up to 38,000 homes and will contribute to meeting the Scottish Government’s targets of providing the equivalent of 100% of Scotland’s electricity generation from renewable sources by 2020.

  • 小型飛翔体／海外 ［Format 2］ Technical Catalog Category
    小型飛翔体／海外 ［Format 2］ Technical Catalog Category Airborne contamination sensor Title Depth Evaluation of Entrained Products (DEEP) Proposed by Create Technologies Ltd & Costain Group PLC １．DEEP is a sensor analysis software for analysing contamination. DEEP can distinguish between surface contamination and internal / absorbed contamination. The software measures contamination depth by analysing distortions in the gamma spectrum. The method can be applied to data gathered using any spectrometer. Because DEEP provides a means of discriminating surface contamination from other radiation sources, DEEP can be used to provide an estimate of surface contamination without physical sampling. DEEP is a real-time method which enables the user to generate a large number of rapid contamination assessments- this data is complementary to physical samples, providing a sound basis for extrapolation from point samples. It also helps identify anomalies enabling targeted sampling startegies. DEEP is compatible with small airborne spectrometer/ processor combinations, such as that proposed by the ARM-U project – please refer to the ARM-U proposal for more details of the air vehicle. Figure 1: DEEP system core components are small, light, low power and can be integrated via USB, serial or Ethernet interfaces. 小型飛翔体／海外 Figure 2: DEEP prototype software ２．Past experience (plants in Japan, overseas plant, applications in other industries, etc) Create technologies is a specialist R&D firm with a focus on imaging and sensing in the nuclear industry. Createc has developed and delivered several novel nuclear technologies, including the N-Visage gamma camera system. Costainis a leading UK construction and civil engineering firm with almost 150 years of history.

We will be close to delivering the targets we have set for 2032 for energy efficiency, low carbon heat and transport. Our electricity and gas networks will be fundamental to this progress across Scotland and there will be new ways of designing, operating and regulating them to ensure that they are used efficiently. The policy context The energy transition must also be inclusive – all parts of society should be able to benefit. The Scotland’s Energy Strategy sets out a vision options we identify must make sense no matter for the energy system in Scotland until 2050 – what pathways to decarbonisation might targeting a sustainable and low carbon energy emerge as the best.
