The
most significant and innovative energy solution in decades.
Completely changing the global energy and climate debates.
Use
off-peak wind energy to recycle
waste CO2 into transportation fuels.
This could cut CO2 emissions In half by mid-century.
Fuels from
CO2 are the best solution for scalable and sustainable
transport fuels, climate change, energy storage,
grid stability, and economic growth.
There is sufficient potential off-peak wind
energy and point-source CO2 in the U.S. to make
twice as much liquid fuels as we currently consume, while
also meeting our other energy
needs.
A Tale of Two Crises: We
will soon face an energy crisis that
could potentially devastate the
world’s economy as global oil supply
peaks. We are also facing the unparalleled
threat of global warming.
These crises are greater than any society
has ever faced before, and they are entwined… The
energy crisis could be postponed (at
great cost) by
relying on
shale oil, tar
sands, deep ocean oil wells, and
coal-to-liquids, but that will dramatically
worsen the environmental crisis.
There are certain avenues that can be
followed that could help reduce
global warming but would destroy the
global economy (for instance to immediately
ban
the use of coal power plants).
We present a new direction
for solving both crises
simultaneously. Using off-peak
wind or other renewable energy (off-peak: in the middle
of the night, when the grid doesn’t
need the energy, so it’s available at low cost),
we can efficiently and competitively recycle the
exhausted CO2 from
coal and natural gas power plants into fuels that work with
today’s
transportation infrastructure. These competitive fuels will
eventually provide enough supply to lower fuel prices and end
the energy
crisis, while eliminating the consumption of fossil oil, tar
sands, shale oil, and coal-to-liquids. This will dramatically
reduce greenhouse gas emissions while improving both the
local and
global economy. When the these fuels made from CO2 (using
wind energy) are burned, no new carbon
will be released. These fuels made from CO2 are
carbon-neutral.
Use
recycled CO2, water and wind energy to make
liquid fuels such as gasoline, diesel, and jet fuel.
No Magic. Just good physics,
chemistry and engineering.

1. Wind
Farms will
generate the electricity required to produce hydrogen
via electrolysis.
Using off-peak (night time) wind
energy keeps costs down. |
2. Electrolysis:
electric current (from wind turbines) is passed through
water (H2O)
to break the bonds between hydrogen and oxygen.
This yeilds hydrogen (H2)
and oxygen (O2) gases.
|
3. Reverse Water
Gas Shift (RWGS).
In a RWGS reaction, some Hydrogen
(H2)
is added to CO2 to reform CO2 into
water (H2O)
and carbon monoxide (CO).
CO2 + H2 -----> CO + H20 |
4. Renewable
FTS (RFTS). In
our renewable
FTS process,
CO and H2 are
chemically reformed into liquid hydrocarbon fuels
including gasoline and jet fuel.
(In traditional fossil FTS, the CO and H2 are
provided by coal. Unfortunately large amounts of CO2 are
released in that process.)
We don't need coal. We just need CO from
CO2 and H2 from
water.
|
| 5. These fuels made
from CO2 (gasoline, diesel, ethanol, and jet
fuel) can be transported in trucks and distributed in our
current gas stations and fuel stations. |

No experienced chemist has
doubted that it is possible to convert CO2 into
standard fuels (like gasoline diesel, and ethanol), or that
the theoretical limit to the efficiency of doing this is probably
between 75% and 90%. The problem has been that prior proposals
for doing this conversion have had efficiencies of only 25%
to 35%. In other words, the chemical energy in the liquid fuels
produced would be only 30% of the input energy required, and
that input energy would be mostly electrical, which is expensive – except
for six to 10 hours in the middle of the night.
The combination
of the eight major technical advances we
have made over the past few years will
now permit this conversion
to be done at much lower cost at 60% efficiency. That’s
high enough efficiency for carbon-neutral fuels made from
waste
CO2 to
easily compete with petroleum,
especially when the input energy is from off-peak wind. These
processes have been simulated in great detail, and are absolutely
sound. Hundreds of distinguished
scientists
and
engineers
have
reviewed
the materials on this website, and no significant technical
problems have yet been identified.
Our breakthroughs permit
production of carbon-neutral ethanol, gasoline, and many chemicals
from
waste CO2 and
off-peak (low cost) grid energy that will be competitive
in the open market.
An average
acre of land in the Dakotas, Kansas, or Wyoming will
produce 5 to 20
times as much fuel from wind, water,
and CO2 as an average acre of land
in fertile farming areas devoted to biofuels.
Serious
about Sustainability. Successful civilizations
have always planned carefully for the
future – not just of their children or grandchildren,
but for their great-great-grandchildren and beyond. Today,
we are “fiddling...,
and arranging chairs on the deck”, while an energy
catastrophe looms that will dwarf the financial meltdown
and depression of
2008 if we don’t begin taking it seriously. This
impending catastrophe is not just for our children, or
our grandchildren,
but even for us.
Everyone has heard a lot over
the past six years about (global) peak
oil, and within the past year
the DOE has finally accepted
that peak oil is coming decades sooner than they were saying
just a few years ago. We expect peak oil in 2015. That doesn’t
mean global oil production will drop sharply after 2015,
but even a very slow decline rate will send prices soaring.
The $147/bbl
we saw in mid-2008 will look cheap by 2015. It’s true
that Canada theoretically has enough tar
sands to forestall peak oil
for several more decades and the U.S. has lots of oil
shale,
but these resources won’t be developed fast enough – partly
for environmental reasons.
On those occasions over the
past 5 years when natural gas prices spiked, we heard some
analysts warning that North America would
see peak gas within 10 to 20
years; but then the price would drop and the need to think
about peak
gas would be forgotten. The most recent EIA data (July, 2009)
indicates there may be enough natural gas (NG) in the US
if all probable and possible reserves can be utilized (and
this includes all shale gas and coal-bed methane) to meet
our current usage rate for about 100 years. However, gas
currently supplies only 20% of our energy, and the cheap
gas (onshore conventional) will account for only 25% of domestic
gas production by 2015. Most shale gas will be very expensive.
Analysis of official IEA data now indicates global peak gas
is likely around 2028. As we approach peak gas, its price
too will
go through the ceiling and force us to adjust our usage to
meet the slowly declining production.
Almost no one has heard of peak
coal or peak
uranium – because
the DOE continues to say we won’t run out for more
than a century. However, the recent research by Prof. David
Rutledge
(Caltech) shows that global coal resources have been greatly
overstated, and others have shown the same is true of economically
recoverable uranium reserves.
It’s true, we have enough
coal in the U.S. to last us 80 years at our current
usage rate (1 Gt/yr). However,
the combined coal production of China, Europe, India, and
Japan was 75% of their coal consumption in 2006, and it will
be half of their consumption in 2013. They will then be
importing twice as much coal as they are today. By 2020,
they will
all happily pay 20 times what they were paying a few years
ago to keep their lights on. (The exporters will charge that
much
because the impending peak gas and peak coal will be undeniable.)
If the importers will pay that much, we won’t pay much
less in the U.S. Global peak coal can be expected before
2030, and peak uranium will come before mid century. The
latest evidence indicates we have already passed peak coal
consumption in the U.S.
We may take some comfort in
knowing that because
of peak oil (2015), peak
gas (2028), and peak coal (2030), total carbon emissions
over the next five decades will be much less than even the low-emissions
scenarios of the IPCC reports. But this is small comfort,
as
over 2 trillion tons of land ice have been lost since
2003, and the 2008 Greenland
summer ice melt tripled the 2007 record. If
we do not start seriously working hard to avoid a cataclysmic
energy crisis, the impact will be additional calamity
to the planet and its people.
We saw in mid-2008 what can
happen when oil demand comes within 2% of oil supply
capacity. Imagine what would happen if oil,
gas, and coal demand were all within 1% of supply capacity!
The world would be in complete
chaos.
This doomsday scenario is not necessary, but the current efforts
toward sustainability are not nearly sufficient to avoid it.
Changing the global energy infrastructure will take decades of
major commitments.
We’ve taken some hard
looks at the serious limitations of the current efforts
toward sustainable alternatives on
this website, and we have explained why fuels from CO2 offer
our best
hope for a transition toward a sustainable, prosperous
future. These fuels will be over 90% carbon neutral, and they
are completely
sustainable. When the last coal power plants are shut
down in 2080, the needed CO2 will come from biofuels
refineries, cement factories, steel mills, and the atmosphere.
We hope you’ll
begin by spending a few hours studying the
research we’ve
presented on this website. Then let your Senators
and Representatives know that what is currently being done
toward
sustainability is not nearly enough to avoid
oil price shock beginning by 2013 and a global energy catastrophe
by 2018, but Doty Energy has
a plan that will work.
The sooner we begin directing resources
toward the development of these fuels made from CO2,
the sooner we can rest assured that our transportation
fuel, agriculture, civilization, and climate are secure
for future generations.
