Abstract: A superconducting electrical power distribution network has a superconducting bus bar and superconducting cables electrically connected to the bus bar at respective joints distributed along the bus bar. The network further has a first coolant system for providing first cryogenic fluid and first circuits for circulating the first cryogenic fluid provided by the first coolant system. The first circuits comprise: a bus bar flow path which extends along and thereby cools the bus bar, cable flow paths which respectively extend along and thereby cool the cables, cooling junctions where the bus bar and cable flow paths meet at the electrical connection joints, inflow lines which send the first cryogenic fluid from the first coolant system to the flow paths, and outflow lines which remove the first cryogenic fluid from the flow paths.

Abstract: A storage tank for gaseous hydrogen includes a continuous tank wall defining a serial array of hollow elongate tank portions of substantially constant cross-section and hollow connecting portions defining an internal storage volume, wherein adjacent ends of any pair of adjacent hollow elongate tank portions are connected by a hollow connecting portion having a cross-sectional dimension smaller than those of the adjacent hollow elongate tanks portions. The tank may be included in an aircraft wing such that it extends spanwise through one or more internal spars of the wing, thus providing a continuous gas storage volume at a given chordwise position notwithstanding the spars, and providing for storage of gaseous hydrogen at higher gravimetric efficiency than is achievable by a plurality of coupled discrete tanks disposed between the spars.
