Kuo, Kirsty A.; Hunt, Hugh E. M. (2015): Isothermal pumping analysis for high-altitude tethered balloons. In R. Soc. open sci. 2 (6), p. 140468. DOI: 10.1098/rsos.140468 

"This paper examines the pumping requirements of such a delivery system. Cases considered include delivery of hydrogen, sulfur dioxide (SO2) and powders as fluid-based slurries. Isothermal analysis is used to determine the variation of pressures and velocities along the pipe length. Results show that transport of small quantities of hydrogen to power fuel cells and maintain balloon buoyancy can be achieved at pressures and temperatures that are tolerable in terms of both the pipe strength and the current state of pumping technologies."
