Hot hydrogen would work, since the temperature of the atmosphere is
typically pretty low, just as hot air balloons work in an air
atmosphere. A Vacuum balloon (assuming you could build it to withstand
the gravitational metric) would work as well, but that would require a
whole nother set of calcualtions...
