Group 4 – Marine Energy James Glynn Kirsten Hamilton Tom McCombes Malcolm MacDonald To Recap … Project Definition Investigate the characteristics of the tidal resources in Scotland and demonstrate how to match those resources with the appropriate Marine current technology Plan Stage 1 - Investigation Resources Technology Stage 2 - Analysis Methodology to match technology with resource Case study Stage 1 - Investigation A. Resource Investigation Identify current weaknesses in available resource data Obtain ocean topography charts Select sites in the west of Scotland based on current research, specific criteria, and surface velocity Calculate shear profiles according to bathymetry of selected sites Correlate shear data with surface velocity to derive velocity distributions B. Technology assessment Generic Modelling of three tidal technologies: horizontal axis, vertical axis and oscillating hydrofoil devices Oceanographic Hydrodynamic Suitability of each type Potential packing densities Define suitable conditions for each technology in terms of depth, velocity, surface roughness etc Stage 2 - Analysis Methodology Develop a frame work to assess each technology suitability for each resource characteristic Define rules to match technology with particular resource characteristic Case study Demonstrate the implementation of this methodology for at least one Scottish West Coast site, most likely Hebridean Sounds Prove robustness of work and further qualify methodology Literature Review There are a number of relevant research projects that have been undertaken in marine energy We are going to briefly discuss some sources of information, highlight the conclusions, relevant information and differentiation between past research and our proposal Information Sources discussed in following section: Past projects Tidal Resource Stream DTi Work Carbon Trust Baraj et al Past Projects 03/04 “Base-load Supply Strategy” Area of concern: To investigate the potential of marine cu
