Hello Mark and all,
as expected, I'm tardy with a response, and I see the discussion has
moved on, and as already noted, shows why hydrogen is typically OT for
this list.
I'm not prepared to debate the merits of hydrogen as a fuel or energy
store here. I had those debates from the late 1990s to 2006. My stance
now is you have to read my book to continue the discussion, because the
issues with hydrogen are many, and you have to solve all of them to have
a valid contender.
To your specific points in your last post.
We have made incredible advances in greening the grid, and I have been
an active participant in that. I charge EVs primarily in Ontario and
Quebec.
Quebec has zero coal, zero natural gas generation and a trivial amount
of diesel generation for communities not connected to the North American
continental grid. The bulk of their generation comes from big hydro,
although small hydro, wind and PV are growing from a small foothold.
All in all, over 99% electricity generation from renewables. Not by
2045. Today.
Ontario has made significant strides in the past decade, in no small
part due to the efforts of the Ontario Clean Air Alliance. Ontario
generation has zero coal, 4% natural gas (shrinking), a serious amount
of large hydro, and growing amounts of wind and PV.
We're not done yet. We are seriously over-invested in nuclear and
continuing down that wrong path. Our new government is in favour of
dinosaur generation sources, and cancelled over 750 signed renewables
contracts in their first month in office (breach of contract lawsuits to
follow) and our EV purchase incentive program. Shutting down all
coal-fired generation in Ontario is the single largest greenhouse gas
emissions reduction project in North America to date.
All in all, less than 4% generation from fossil carbon sources (natural
gas and diesel generation in remote communities). Still, we aren't
finished yet. Storage projects are continuing to be built to displace
the need for the gas peaker plants. Old small hydro plants are being
upgraded. Remote communities are being connected to the grid to
eliminate the need for diesel generation.
We have also made incredible progress in making battery electric
vehicles, especially the battery technology, sufficient for most driving
needs, reliable and affordable. There is excitement in that field and
no indication the cost and storage capacity trends are going to change
anytime soon. We are also making substantial strides in provisioning a
charging network throughout the industrialized and industrializing world
to support away-from-base charging, to extend the utility of battery EVs
in every day missions. And we're working on how to continue in those
directions while supporting, not threatening, electrical utilities and
grid reliability.
As for my sources on hydrogen technology, they include hydrogen
proponents, scientists, engineers, journals in multiple fields, and
various news media. The hydrogen skeptics don't bother poking me. And
for clarity, regarding hydrogen, I did not say nothing has changed, I
said things have not changed much on the technology side other than
increasing on-board storage.

We?ve made incredible progress over just the last few years in greening the
grid.
By 2045, it should be 100% renewable. By 2030, transportation hydrogen should
be 100% renewable.
(BTW, if you think that nothing else has changed in hydrogen technology in the
last several years, there is something wrong with your sources)
