Industry Growth

Global Perspective

  • Commercial-sized in-stream tidal turbine demonstration devices have been deployed in the UK, Canada, France and South Korea
  • There are now plans to install small arrays with a capacity of between 4MW and 16MW
  • The tidal energy development momentum is building
  • UK’s Marine Energy Industry forecasts – $9.45 billion value by 2035

Ambitious Goals for the United Kingdom

The UK plans to install 100-200MW of tidal and wave capacity by 2020

Canada’s Marine Energy Resource

Canada’s Marine Renewable Energy Technology Roadmap provides a vision for Canada to become a global leader in marine renewable energy production systems and technology. tidal projects to date are in the works for the FORCE test site. They have been approved by government to receive feed-in tariffs to reflect the cost of turbines and their deployment.

The extractable tidal energy capacity for the Minas Passage in Nova Scotia’s Bay of Fundy has been estimated to be 2500 MW. Nova Scotia has authorized feed-in tariffs for developmental tidal arrays that reflect the cost of the turbines and their deployment, and is currently developing strategies and infrastructure for commercializing marine renewable energy. Four projects totalling 17.5 megawatts are currently in progress.

Tidal Currents at Cape Split in the Minas Passage

The Fundy Ocean Research Center for Energy (FORCE) is an example of tidal energy industry collaboration and development in Nova Scotia, Canada. This commercial-scale, shared infrastructure ‘incubator’ initiative in the Bay of Fundy is cited as a world-leading, grid-connected, shared-infrastructure demonstration centre with the capacity to aggregate individual trials into a 5 MW power plant, with the goal of scaling up to arrays totalling 65 MW.Tidal Currents at Cape Split in the Minas Passage

 Tidal Power: Market Size & Dynamics

  • Fossil energy costs are increasing
  • Renewable energy costs are decreasing
  • Renewable energy companies are now becoming profitable
  • Marine Renewable now in line to be developed
  • 800 TWh/yr worldwide tidal energy potential
  • 100 times the potential of Fundy’s Minas Passage
  • UK is tidal power leader (plan: 100 – 200 MW tidal/wave by 2020)
  • Canada is a major player – (Target: 15 – 20 MW tidal by 2020)

Tidal Power: Issues & Constraints

  • Hostile underwater environment
  • Higher deployment & maintenance costs
  • Higher entry costs
  • Early stages of development
  • Design standardization & rationalization needed for cost competitiveness with other energy sources
  • Cost reductions will incent financing for large-scale projects

Unmet Needs:

  • Efforts to date have been in turbine efficiency
  • Little research on substructures
  • Cost and risk need to be reduced

Some Solutions

  • Easier deployment
  • Easier turbine access/maintenance
  • Efficiency of installations needs to be increased
  • More turbines per substructure
  • Ability to place in water column sweet spots
  • Structure standardization
