Looks like deuterium is ~$3000/kg, as heavy water is ~$600/kg [1]. Less expensive than I thought, but still far more expensive than hydrogen at <$0.01/kg when purchased from my local public utility.
It's unfair to compare with hydrogen though - this study [2] suggests that fusion and wind power are roughly comparable in cost.

- DennisP 14y agoThe best comparison is really to the 12 million kilograms of coal that generates the same amount of energy: http://www.euronuclear.org/info/encyclopedia/f/fusion.htm http://www.euronuclear.org/info/encyclopedia/f/fusion.htm I'm guessing your second link is based on tokamaks, which are generally considered likely to be far more expensive than some of the lesser-known designs. If they project tokamaks to be competitive with wind then I'm pretty encouraged.
