Methods and apparatus are described for producing lift gas to enable balloon launch or to allow the prolongation of balloon flight. In one example, the method may include reforming a fuel source by reaction with water to generate hydrogen-rich lift gas mixtures, and injecting the lift gas into a balloon. The reforming operation may include causing the combustion of a combustible material with ambient oxygen for the release of energy; and heating a reforming combination of reaction fuel and water with the energy released from the combustion of the combustible material, to a temperature above that required for the reforming reaction wherein the fuel and water sources are reformed into lift gas. In one example, the amount of the combustible material combusted is sufficient to result in the release of enough energy to heat an amount of the reforming reaction fuel and water sources to the temperature above that required for the reforming reaction to proceed. Membrane or other gas separation devices may also be used to reduce the molecular weight of the lift gas produced by the reformer, thereby improving its quality for balloon flight applications. The lift gas may be used to launch balloons from the ground. It may also be used to extend the flight duration of balloons in the atmosphere.
