Hydrogen cannot travel faster than the speed of light neither is it replenish-able in space. There is no magnetic field nor electric field propagating through spacetime. However there is a continuous gravitational field that can be tapped into. Even our solar system rotates around the milky wave using this gravitational field. It is of interest to pursue the development of 'Field Propulsion' engine.

Unfortunately, unless our understanding of physics changes radically, that won't be possible any time soon. Gravity is not a force, and we do not have the means to distort space. If we did, you might as well go for making a wormhole for the fastest trip times :)
