The City of Liverpool, England, has unveiled advanced proposals to build the world’s largest tidal power generator on the River Mersey.

If it’s built, Mersey Tidal Power would become the largest tidal range scheme in the world. It would power more than 1 million homes for more than 120 years.

The dam-like Mersey Tidal Power would be a barrier between the Irish Sea and a tidal basin. It would be fitted with turbines and tap into one of the UK’s largest tidal ranges to generate power with two-way generation.

It would connect Liverpool and the Wirral peninsula and could become a pedestrian and cycling link across the Mersey. It could also provide future flood defense.
