  We show efficient laser driven proton acceleration up to 14MeV from a 50
$\mu$m thick cryogenic hydrogen ribbon. Pulses of the short pulse laser ELFIE
at LULI with a pulse length of $\approx$ 350 fs at an energy of 8 J per pulse
are directed onto the target. The results are compared to proton spectra from
metal and plastic foils with different thicknesses and show a similar good
performance both in maximum energy as well as in proton number. Thus, this
target type is a promising candidate for experiments with high repetition rate
laser systems.
