The slight water content in hE15 makes it cheaper to produce than pure E15, as it takes a lot of effort to eradicate the last bit of water from the ethanol. And even though it produces less power than pure E15, its relative efficiency is slightly better so the effective drop in efficiency is less than the 1% you'd expect from the water content %.

Actually, hE15 is the only ethanol-containing fuel on sale here in any quantity. I have to make a detour to get it, but will do so one day for the sake of science
