If i were to build a dam in a river, to focus the flow of the water and try to harness it. I guess i would create some sort of wheel that would be spun by the power of the water. How do i turn this into energy and eventually even store it?

I think making something like Hydrogen is one of the better ways to store energy if you absolutely have to store it. Burning Hydrogen is “green” as the product is just water and you can burn it in fuel cells making electricity without intermediate steps. Main issue is that Hydrogen takes up way too much space, but it’s not as important if you can set up a facility for it.
Converting rotational momentum of a turbine into electricity is pretty easy, copper coils and magnets do the job for you.
In general, storing energy is hard and prohibitively expensive, people usually use energy as is right away and just produce more when needed.
