intermittency. By generating closer where the energy is used we are
greatly reducing the need for transmission. By reusing the

efficiency is low, but who cares. The storage is incredibly huge.
Inertia energy itself pays for itself 50x this way and its instant.
Look up Long Duration Energy Systems. This is the scramble that is

From your executive lineup, I'm sure you guys are doing both the
engineering work as well as the financial/legal work to try to make this
concept viable. It seems like a "niche" application but not as niche
as the CAES perhaps. It seems like you are cashing in on the
serendipity of the nature of NG power generation infrastructure. I had
a shop teacher in HS who taught ICE basics on a small diesel engine he
had converted to run (low power/speed) on compressed air.
I trust that even if YOU don't work hard on the problems of conversion
efficiency, it seems likely that others *are* working on that problem to
cash in on the marginal gain. The "efficient market" to the rescue.
Since the conversion efficiency (I believe) is primarily about
heat/coolth dissipation on both ends, that low-grade heat on the
re-generation side is appropriate (direct solar collection, geothermal,
heat-pump). I'm not positive, but it seems as if the transmission
losses are less than with electricity.
I see from your preliminary literature you are also planning for the
direct use of "waste" heat on one side and "waste" coolth on the other
as an industrial product. The passthrough of compressed air to
industry is also auspicious... minimizing the conversion inefficiencies
by skipping intermediate steps... I doubt many industrial contexts have
a compressed air source, but rather have to create it on-site with ICE
or Electric to-mechanical-to-compressor.
As an amateur complexicist, I am a fan of multi-scale systems.... so I
look forward to systems like yours not being scaled (only) to
mega-industry. I wonder at how far out the existing distribution chain
you can push compressed air practically? I doubt there are (m)any
mechanics or private homes, for example, who could give up their NG feed
(heat mostly) for compressed air, even if the upstream distribution were
converting. The new(ish) DC-powered residential scale mini-split
heat-pumps would seem to operate well off of any mechanical energy
source (not just PWM modulated variable speed DC motors) and the
decompressed chilled air from the air-motor would go right into boosting
the efficiency rather than being yet another source of waste heat. Not
a perpetual motion machine, just a system where some of the intrinsic
inefficiencies are exploited/recovered elegantly?
The big win seems obviously to be the major NG pipelines and existing
electric generation stations. I can't tell from your literature if
converting existing NG turbines to compressed air is even reasonable...
seems like this is probably why CAES is burning NG to bring the charge
up to the performance scale of existing turbine designs? I believe
that many of these plants were designed/modified to be "peaking" plants
which it seems your tech is ideal for... let the
Again, it is nice to hear someone here with a practical
application/aspiration in the domain of infrastructure/industrial/energy
transformation. Many of us are a bit too close to the academic side of
problem "solving".

That is a famous prototype. Recently Hydrostor made headlines
building new CAES plants. The main issue is the need of a salt
cavern. The amount of possible sites is very small. The caverns
are used to mine salts for bleaches/chemicals or to store natural
gas. This tech is $111/kwh.

Hi Frank:
We need any, but hopefully renewable energy, to generate power
for the compressors. This also creates heat which we can
recycle for more electricity or use for industrial purposes.
Our efficiency isn't high, but once we are in the pipelines we
have a huge battery. 60 miles, 36 inch diameter can hold
240MWh. We can be instant inertia energy or generate. Our
storage costs are about $50/kwh. Batteries are $400/kwh for
example. Also, we can store compressed air for months upon
months. Also, if we can build the renewables close enough to
the plant we can go DC/DC which is a 25% energy savings not
having to convert to AC.

Hi. I'm a reader more than a contributor, but the
Hydrogen discussion is close to my day to day.
Many of us in renewables think Hydrogen might mostly
be kick the can as Steve mentioned. It is something
that might be economically feasible in the 2030s and
so the length of time oil companies sell oil
increases. Having said that, there are a number of
very pricey Hydrogen projects getting funded. That
might be showing how profitable the O&G industry is.
I'm working with a company we call Breeze
<http://www.breezesqueeze.com>. It uses compressed air
in pipelines to move turbines at power plants.
Without fossil fuels or using water this is getting a
lot of attention. There are many advantages such as
cold air where compressed air is released that can be
used by data centers. 25% of all GHGs come from
generating electricity. 45% of all water used in the
US is used to create electricity.
We see this as a better option than Hydrogen. We do
think Hydrogen fuel cells are a solution for mobile
applications.

Must we always begin with the assumption that
growth in terms of geographical/geometric,
material and energy consumption/appropriation are
requisite to continuing/growing a "prosperous
society"? Tangentially (or not), if "green"
hydrogen implies a 2:1 ratio of CO2 production to
H2 but often begins with fossil fuels, it is
obviously yet another "kick the can down the road"
solution. Harvesting solar and
direct-solar/lunar-derived energy (including wind,
tidal) and channeling it through our living
(including technological infrastructure and
agri-industry) systems to yield high-entropy
"waste heat" seems to be orders of magnitude more
sustainable (if still questionable on some very
long time-scale limited by a
Dyson-Sphere-like-limit). If the H2 is created by
cracking H20 (and capturing both to be recombined
later to release energy) using solar (and other
renewables) energy it is a *closed cycle*. One
would presume the total amount of H2 we would have

From ecology there comes the observed phenomena of
"island syndrome" which can include island
dwarfism and poikilothermy which are both driven
by reducing the demand on finite resources without
giving up function or complexity.
From Alexander Payne comes the absurdist SciFi
flick Downsizing
<https://en.wikipedia.org/wiki/Downsizing_(film)#Plot>
which postulates by shrinking humans by ???-fold
(5 inches tall ~= 12:1 in 1 dimension, 144:1 in
cross section and 1728:1 in volume/mass... ) the
movie implies no change in metabolic rates which
would nominally speed up with "shrinkage",
yielding (also) shorter lifespans. Oh well..
Fiction. But the point would seem well taken...
Gaia would get a 2000:1 reprieve from our
*current* energy/mass burden on her systems.
I'm not promoting shrinking people as-such, just
noting that our 0th order instinct is growth, and
supralinear if at all possible, up to and likely
achieving Kurzweillian asymptotic resource
consumption.
On that note, I believe that the myriad
technological singularity concepts all point
toward increased complexity and downscaling to
extend the use of material and energy, driving up
the effective collective metabolism of "the
system" and paradoxically *increasing* the rate at
which we approach any of the jillion ecophagic
gray-goo
<https://en.wikipedia.org/wiki/Gray_goo>-like
scenarios neo-luddites like me might contrive.
I assume (but have not yet poked around for) that
Alifers have already studied the multi-scale
*structure* of negative entropy profiles in
complex systems-of-systems. I think Glen has his
ear closer to that rail than some here? EricS?

my little-toenail-purchase in the community in the
early 2000s - Symbiotic Intelligence ALifeVI

This reads so naive yet (mildly) prophetic now...
