Purpose of Talk

• Irelands energy resources
• Review of risks to future supply
• Reducing the problem with wind and others
• Solving the problem
• Harnessing the vast kinetic energy resourse in
  sea currents using Deflecting Vane Technology
  
• DVT is the Solution to European and World Energy
  Needs
  
• Hydrogen Fuel and Energy Storage

Depletion is easy to grasp

• As ASPO makes clear
• Oil Gas are fossil fuels formed in the
  geological past
  
• We started running out on Day One
• BUT running out is not the issue
• What matters is PEAK DECLINE
• When will the peak arrive?
• What is its impact on Ireland?

Energy Density Enhancement

• One of the major advantages the DVT system has
  over other converters (which use propellers
  aerofoil or oscillating vanes) is that the energy
  density of the flow reaching the turbine has been
  enhanced at low cost and is more than three times
  that entering the other converters.

The Breakthrough Stages in DVT Evolution

• Threefold increase in energy density at turbine
  entry (Not possible with propeller systems)
  
• Breakthrough in bearing protection with overall
  cost savings and reduced shutdown time
  
• Problem of marine growth on vanes has been
  resolved
  
• Onsite topography requirement recognized. Some
  sites have significant advantages
  
• The 24 hour cycle incorporates a energy storage
  sequence to capture best market price
  
• The structure is semi-submersible and maintains
  best position relative to the surface
  
• Main buoyancy is well below the surface, safe and
  away from storm waves
  
• The main elements of each platform and facility
  are in multiplies and are dispersed
  
• The dispersed underwater nature of the system
  facilitates protection against attack

Gas

• Gas comes from vegetal remains not algae
• and from overheated deep oil
• More generated but needs a better seal
• Depletes faster
• End comes unexpectedly
• No market signal
• US experience

Ireland is very vulnerable

• Ireland is very vulnerable
• no coal or oil to speak of
• one nearly depleted gasfield
• one new gasfield offering temporary relief
• relying on increasingly unreliable supplies of
  gas from UK and Europe
  
• very much at the end of the line with many hungry
  people upstream

The Sea Current Option

• The greatest source of renewable and sustainable
  energy is in the kinetic energy of sea currents.
  
• Harnessing this energy could satisfy the Global
  Energy Requirement
  
• Research is currently underway to find a solution
  
  
• There are a number of propeller systems
• There are oscillating vane and aerofoil systems
• These solutions are trying to adapt wind
  technology directly to a dense slow moving fluid.
  
  
• Deflecting Vane Technology is the only two stage
  approach and the logical way forward
  
• It increases energy density upstream from the
  turbine by a factor of 3
  
• Help is needed to spread the good news worldwide

Economic Obstacles

• The market always prefers the easy and cheap
• It is incapable of anticipating discontinutities
• Discounting impedes long term projects
• It is a matter of National Policy
• even survival
• It is better than War

Time is short

• Radical changes affect all aspects of society
• Special interest groups need attention
• The administrative challenges are very great
• The time to start is NOW
• Ireland will have great advantage if it plans
  ahead of its competitors

Platform Life Factors

• Structure design based on Stress Analysis Model
• Identification of high/med stress areas
• Design for 30 years incorporating a concept of
  optimum economic operation maintenance
  
• Energy capture, conversion distribution
  facilities modular for easy disengagement for
  onshore repair
  
• Operation Maintenance strategies activities
  finalised before design approval

Irelands solutions

• Ireland has some advantages
• It can weather the storm if it adopts the right
  policies.
  
• Above all, it has a small population and a
  fertile land
  
• What should it do ?
