Tidal input to the national grid could match Hinkley nuclear in cost and quantity
Fusion or fission, nuclear power is not the only reliable alternative to fossil fuel (“Britain’s energy dilemma: if not nuclear power, then what?” News). Sunshine, wind and waves vary with the weather, but tides still rise and fall and the flow can be safely harnessed in and out.
With nuclear fission not yet in sight, this simpler seapower could be a better bet than a rejigged evolutionary power reactor at Hinkley Point C. In his autumn statement last year, George Osborne flagged up the prospect of a tidal lagoon power project in Swansea Bay, only to put it out for review when the price of oil and gas came down.
