What hype? I can't see any hype. I only see negative hype, trying to trash hydrogen.
Whilst we are not green, the hydrogen is not green, but it does not prevent us from going green, in fact it encourages us to go green, solar is the cheapest source to produce it from, so production of it will move completely to solar, sooner rather than later.
Solar and hydrogen go together like strawberries and cream, seriously, there are god-signs all over it.
There is no reason why it will not replace all batteries, circulate clean drinking water when used in transportation, make aircraft fly (Even some long grounded classics like Concorde), provide fuel on every street corner, and even produce food, independently of the conventional food chain (See "Solein" - hydrogen is the magic energy ingredient).
So it solves many problems.
The only thing standing in the way of it right now is failure of the governments to monetise what we've put to use of solar already.
They are busy trying to penalise us by taxation, for daring to use energy other than as supplied by the now struggling utilities companies, so the latter might be propped up by the government, when exaclty the opposite is needed, but for what? We don't need utilities energy any longer, it takes less than a year for all communities including even government itself to install the solar hydrogen infrastructure it needs to generate its own energy and wealth, ending the need for collection of taxes.
As things stand, money is issued on oil, or town gas, or anything extracted, since extraction is a kind of work, the debts upon which the money is issued can be redeemed from the work of extraction.
But there is no work of extraction in the case of producing hydrogen, or actually any economic product from solar.
So right now, there is a shortfall between money issued, and product created, because a lot of product has been created, but no money issued for it.
Hence the real reason for inflation.
Until they start issuing money for free, the product created from solar will stay unmonetised, and will continue to accumulate, further impacting the value of money, so we will see inflation continue to spiral to levels never seen before, because as the extracted energy industry declines, and the solar industry scales up, money is becoming increasingly representative of... nothing.
When they do start issuing it, of course we will use it to finish off the job of scalng to 100% solar.
Sorry long reply, but this only scratches the surface. I have spent the past six years researching it. I write a lot about it, you might see in my profile, but it is not pushed much to folk, because it isn't about profit, its about the end of profit, and the start of something new, a new kind of economy beyond capitalism - Energyism.
