Tapping into Ocean Power

8 Mar 2017   Tidal, Waves

The oceans of the world are a vast unexploited source of clean, reliable and predictable renewable energy. Could this energy help replace fossil fuels and be a solution to climate change? Humans have been trying to harness ocean energy for centuries, beginning with a French engineer named Pierre-Simon Girard in 1799. The constant pounding of the waves and the ebb and flow of tidal currents, as well as other properties of the ocean, if harnessed, could produce 20,000 to 80,000 terawatt hours of electricity, according to the International Energy Agency. That is more than the world’s current energy consumption of almost 20,000 TWh The Electric Power Research Institute estimates that the waves breaking along the U.S. coastline alone could generate 2,640 TWh each year. But since shipping, fishing, naval operations or environmental concerns take precedence in certain areas, the amount of power that is “recoverable” is estimated at 1,170 […]

Tidal Lagoon Energy in Wales

17 Feb 2017   Tidal, United Kingdom

The report of an independent review of UK tidal lagoon energy was published on 12 January 2017 by a former UK energy Minister Charles Hendry. The report praises the proposed ‘pathfinder’ tidal lagoon in Swansea Bay as a ‘no-regrets option’, and sets out a supportive case for developing the sector. The Hendry Review was commissioned in February 2016 by UK Government to assess the strategic case for tidal lagoon energy as a new industry in the UK. This followed a successful planning proposal by Tidal Lagoon Power (TLP) to develop the world’s first tidal lagoon in Swansea Bay, as well as a subsequent programme for a ‘fleet’ of five larger projects, including three in Welsh waters (Cardiff, Newport and Colwyn Bay). Despite the Swansea Bay project appearing in the 2015 UK Conservative Party manifesto and receiving development consent in June 2015, uncertainties around cost and subsidy subsequently prompted the […]
