The tidal revolution


A recently published research builds upon a combined tidal range electricity generation and cost model, showcasing the viability of tidal range energy in the UK. The research illustrates how it is feasible to preserve the entire tidal range within existing dams or weirs.

The researchers assert that tidal range schemes can protect coastal areas from the impacts of rising sea levels. Simply closing sluices and turbines can restrict high tides to existing levels. Misconceptions and concers about the operation have impeded their development.

Closing sluices and turbines can restrict high tides to existing levels. Also pumping can maintain low tide levels. The studies demonstrate that, with modern technology, estuarine barrages are the only practical means to protect these vital habitats. Coastal lagoons are proposed for various locations around Britain’s coast. These schemes will generate jobs in construction and manufacturing for generations. This includes opportunities not only for transport but also for communication, conservation, and recreation. In the long term, they will provide reliable power with reduced costs.

The UK boasts the world’s second-largest tidal range. Currently, globally, two large-scale schemes are in operation: La Rance in France, completed in 1967, and Lake Sihwa in South Korea since 2011. Both schemes generate significant quantities of cheap, sustainable electricity.

This idea alone could be substantial for the UK. The hysteria surrounding global warming there is as economically destructive as seen anywhere. In the absence of evidence and faced with total projection failures for the warming catastrophe, better ideas need to be exploited quickly. They will need the power, and if they can bear the investment and running costs, it would be best for the UK to proceed with it.
