The reason why this is so important is that simpler molecules are much easier to simulate and work with from the theoretical side to create a bulletproof model of how the high temperature superconductors work. All of the cooper pairs and all that stuff took years and years to figure out because the molecule was something like yttrium barium copper oxide.. which is complicated as all hell to figure out what the electrons are doing inside of it while in a crystalline form.. H2S is basically like "sulfur plus some protons" is so much more simple to simulate with something like molecular dynamics methods to figure out what is going on with it. What the researchers probably are hoping to come out of this is a recipe for superconductivity based upon a crystalline form of some material that can be made in a low-cost fashion that superconducts at high temp..
