"But that would on no way be in the ball park of the energy we get from the sun. Orders or magnatude off."
I'm not sure what you're saying here. The problem is there is too much energy around a black hole. (The paper says 1010-12L⊙ - with planet formation inside 106 AU.) The authors' problem is finding a region cold enough for planet formation to take place, given observational evidence of warm dust. They do that. But it's not inconvertible that the planet could migrate to somewhere slightly warmer - it's a turbulent environment.
I still don't think there'd be life there, but.
