Not a hydro person, but I expect the blades to look very different for water, larger cross section covered by the blades. Those almost look like they are for air, long and skinny.
Serg3y. Blades like those of the propellers of ships perhaps although those shown might be shaped to catch a larger circle of the current. The turbines would need to be clesr of shipping lanes but that, surely, could be managed. For Britain, surrounded by sea, tidal power is surely there asking to be used- a new kind of hydro power and plenty of it.
Shipping lanes are a good concern, and the marine wildlife should also be thought of though, how many already get sliced up from the giant props on ships, these are bigger.
Yes, why has Britain, a marine nation, been so reluctant to make use of it? Even existing offshore wind farms could have water turbines beneath them, free extra power for the taking.

This is a very poorly written project. Every energy project in the world discuss the power output, cost and total energy over the year. They have confused megawatts (power) with megawatt hours (energy). They also don’t describe the power generation curve during the day (constant or dips for tides). For comparison, the largest offshore turbines in the world, Vestas and Goldwind are 15 and 16MW, have more than 60% capacity factors similar to coal plants and use existing technology to make levelised cost similar to grid prices. As much as I love cool engineering like this, I wish it was run by actual project managers not hype specialists.
