Hydro is electric, so them pumping money into electric cars makes no difference as fuel cells (for hydrogen fit in same place a battery can, the bad thing about hydrogen is the cost of the tech) but the good news is merc have signed a partner deal with a few other brands to develop the tech and get it cheaper, they also have the backing of major oil companies who still want you to pull in and fill up, not charge at home. So really it is the future.
