Humming noise form the engine while driving that gets louder as I accelerate

This morning I started my van and it ran fine. I stopped for a few minutes left the van running so I could run into the store. When I came back out there was a humming sound coming from the engine.

I have never heard this sound before and it would quiet down a bit but then when I accelerated it got louder. My battery light also came on. I drove for about twenty minutes and when I got to work I turned the van off for a few minutes then turned it back on.

It started fine but the humming sound was still there. Are there people out there with the same issue or is this a recall?

Looking for any answers to help.
