Just downstream from the Deep and 60 yards offshore stands this dinky tidal power generator supplying 30-40% of the electricity used by the submarium. This is the Neptune Proteus Tidal Generator and represents a significant step forward in utilising the power of the Humber. Obviously it's a prototype but I expect that we'll see many more and bigger versions as tidal power is clean and, unlike the wind, predictable. Depending on who you believe the tides could be supplying 10-20% of UK power and the Humber, because of its sheer size and large tidal range, will play a major part in that. I'll stop now this is beginning to sound like a sales pitch.
