will improve. Far lower than fires with gasoline.

Well, what he is proposing in that video is just a means of storage, and
appears to have nothing to do with how it is produced or what you produce it
with.
As far as production of hydrogen is concerned, “dirty methane” is used less and
less. It’s been several years already that the industry
Compression is not “an issue”. It’s just something that’s a factor.

MUCH better chance of a battery catching fire than a hydrogen tank exploding.
In fact, the latter is unlikely to happen. The former, it happens all the time.

have their risks too, but they are still a lot safer than a 5000 PSI vessel

This may have been talked about here already, but it is the first for
me where I am not discarding the whole notion of Fool Cells, as I am so
used to calling them.
Seems to still be rather complicated. But it is using electralizers in
stead of dirty methane.

Most here don’t make disclosures, but I will disclose that Plug Power is a

opinion.

Well, I didn’t saw that batteries were inefficient, but they can be.
As far as hydrogen not being efficient or inefficient to produce from
electrolysis, again, not a point I made. But what do you consider efficient?
Economical? Okay, it wasn’t clear you meant that. At a 3¢/kWh cost of solar,

Gee, a lot of incorrect stuff to reply to.
Not incorrect, but you think that PSI is less confusing to use than bar? Then
it’s 10,000 PSI. As far as your description of what it is - frankly, I hadn’t a
clue what you were talking about. Your numbers seem to be confusing a point.

I’m assuming that lead acid is cheaper than comparable lithium. In a riding
mower, weight is of little concern, so lead is much more cost effective. If the
mower has any accessories such as a blade, then the added weight is an
advantage - my ElecTrak is very heavy and so has lots of traction.
