  Experimental discovery of near-room-temperature superconductivity in highly
compressed hydrogen sulfate started a new era in superconductivity. To date,
researchers have made the discovery of dozens of superconducting hydride phases
with transition temperatures above LN2. While the primary focus of the research
in this field is to determine fundamental superconducting parameters of these
superconductors, here we revealed primary applied property of these
superconductors which is the field dependence of transport critical current,
$I_{c}(B,T)$. We analyzed reported $V(I)$ curves for a highly compressed
CeH$_9$ sample with $T_c = 70$ $K$, and showed that this hydride exhibits
practically identical $I_{c}(B,T)$ to HTS 1G-wire
(Bi,Pb)$_2$Sr$_2$Ca$_2$Cu$_3$O$_{11}$. Additionally, we demonstrated that the
$n$-value in CeH$_9$ superhydride follows a nearly identical dependence on
critical current, as observed in Nb$_3$Sn conductors.
