MOF-based hydrogen storage has been around since at least 2003 (Omar Yaghi on MOF-5). Its hardly a novel concept. I haven’t read this paper, I just skimmed for figure out what the “aluminum sponge” was until I saw it was Farha and MOFs. As far as I can tell, this is in Science because it surpasses key benchmarks set by the DOE, not because it’s a new idea.
This is a particularly high surface area MOF (>7300 m^2/g). I recently picked up a MOF project (not related to hydrogen storage) with derivatives of a popular MOF and it’s closer to 1000 m^2/g. Zeolites (a much more established class of porous material) are about a quarter of that (<200-300).
An actual metal sponge (what I thought the article was talking about) is <~20 m^2/g.
