For the first time the thermal desorption of H_2, N_2, O_2 and CO_2 is presented for antimony sulfoiodide (SbSI) xerogel made up of large quantity nanowires. The desorption has been observed near ferroelectric phase transition established at T_{c}=293.0(2) K. The Sievert measurements have shown that the hydrogen uptake is linear function of H_2 pressure (when p < 1.1×10^5 Pa). The hydrogen storage density in SbSI gel amounted 1.24× 10^{-2} wt% (for p = 1.08×10^5 Pa at room temperature).
