Much like anything that's new and improved,h2o2is only spendy if not
having the clean and fully renewable cache of spare/surplus energy to
start off with, and as I'd said before that Warren Buffett, William
Mook and myself will gladly provided all those spare teraWatts of
affordably clean and renewable energy.
The new and improved hybridelectriccar, and of its ICE that runs on
such a composite of clean fuel, is more doable than you'd think.
h2o2as a monopropellant is only worth 2.9 Mj/kg, and the good blend
of low sulphur heating oil or LS diesel is worth 44 Mj/kg.
Keeping in mind that an amount greater than 7:1 as utilized ofh2o2:fossilis going require those 7+ parts ofh2o2per given part of
LS diesel.
7.25 * 2.9 + 44 = 65 Mj/kg of each consumed kg of that SL fossil fuel,
at that there's zero NOx and the absolute minimal amount of CO2
getting contributed per given kg or if you like per Hummer or GM Volt
mile.
Next taking into account, instead of getting 12.5% thermal dynamic
efficiency as obtained from the typical 4-Stroke or 4-cycle engine, of
getting at least twice that good if not nearly 4 times as much because
of using a 1-stroke or 1-cycle ICE that's not wasting all of that
kinetic energy by having to deal with going through all of those
wasted piston strokes. In other words, in addition to having the 65
Mj/kg to work with, it's entirely possible to reach a 50% worth of
thermal dynamic efficiency, and that's not to mention the small size
and minimal mass of this ICE that could be held in as little as one
hand.
The combined density of 1.32 g/cm3 for essentially obtaining 65 Mj/kg
of the LS fuel oil is in of its self impressive.
BTW, that LS diesel can be easily replaced by just about anything,
including the clean alternative fuel obtained from coal gassification
or any number of interesting biofuels, as they'll each burn hot an
clean along with having contributed zero NOx.

Not exactly rocket science, is it.
Road fuel via coal gasification/liquefaction as syngas/synlio/synfuel
offers an amount of stored liquid energy that's worth 34~40 Mj/kg or
perhaps as low as 28 Mj/kg which can get pushed to roughly 36 Mj/kg if
a good amount of waste plastics are incorporated, although the energy
taken for the syngas production itself is substantial and by no means
offers an environment friendly process, often taking a ratio of 3:1 in
order to convert itself into liquid fuel (giving us roughly less than
100 years if all known reserves of coal were to be liquified), not to
mention the lives of coal miners taken and of whatever to do with all
of those nasty death-trap mines and vast open pits of toxic remains
once excavated.
So, it seems imperative that we utilize our fossil fuel reserves in
the best and most efficient way possible, that is unless you don't
mind energy wars and of worse things to come. So, we've got ourselves
roughly another spendy, sooty and bloody century to piss or get off
the pot. Of course by then we may not have to bother with the makings
of h2o2, LH2 or LOx in order to get the most clean energy and/or
mileage from a given amount of fossil fuel because, there will not be
any such affordable fossil fuels to burn, whereas instead every drop
of liquid fuel for our Hummers will have become spendy syngas/synoil/
synfuel of at least $10/gallon if we're extremely lucky.
Lots of nifty information about the consumption of coal with or w/o
capture of CO2, and/or along with fresh water.

"Fischer-Tropsch diesel (FTD) fuel is colourless, non-toxic liquid
that has virtually no sulphur, or aromatics. FTD is not a compound but
a mix of hydrocarbons, mainly from C12 to C20. FTD is today produced
from natural gas and coal with big construction projects under way.
The energy content (LHV) is about 34 MJ/litre (44 MJ/kg) with slightly
lower density than regular diesel."
Similar to LPG, "DME is at normal atmospheric conditions a gas
(boiling point -25ºC) and must be handled under pressure (>5 bar) to
obtain a liquid. DME contains no impurities of sulphur or metals and
is under practical conditions a harmless gas from health and
environmental point of view (is among others used as propelling gas in
spray cans) and is non-mutagenic. DME is synthesised from methanol or
directly from synthesis gas. DME has as liquid an energy content (LHV)
of about 19 MJ/litre (28 MJ/kg) and yields more than 10% less CO2 per
energy unit at combustion compared to petrol."
There are low sulphur formulated heating oils that'll also offer 44 Mj/
kg as road fuel.
Somewhat like extracting oil from oily sand, whereas coal liquefaction
or gasification along with natural gas as used in order to make such
viable petrochemicals is what unavoidably creates a substantial dosage
of carbon dioxide in the process, as great as 4:1 consumption of
medium/low grade coal per given unit of liquified syngas seems
unacceptable at most any price. But what do I know, within a century
from now such synfuel becoming worth $100/gallon could be just the
best ever energy ticket to ride, especially nifty if you're in the
business of making and selling such spendy synfuel.
BTW, big-energy lie No.1 is that trillions upon trillions of
biological fossils in some way created such fuel, when in fact fossils
have damn little if anything to do with their having contributed to
the vast bulk of such global fuel reserves, and that's not my saying
that terrestrial fossils are not incorporated within certain
situations. Instead, most terrestrial fuels are a direct result of
Earth's planetology as having been exposed to and/or having interacted
with a much greater stellar influx than we have as of today. I bet
you folks thought all known life evolved purely right here on good old
mother Earth, and with having but that one and only same old passive
sun.
