Economically Saving the Planet by Efficiently Producing Fuels from Waste CO2 and Off-peak Wind

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.

Our Plan

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.

How expensive must oil be for these fuels from CO2 to compete?

In most cases about $70/bbl, but in some cases only $45/bbl.

 
Fact check: Storing very large amounts of energy in compressed air is 5,000 times more expensive than in liquid fuels. Read more.
 
For those that are interested in a very detailed design summary (and simultaneously interested in helping us to fund continued development), the "RFTS-DetailedDesign-1" can be purchased in hard-copy.

We can shift the geopolitical center for energy from the Middle East to North America.

We can go from importing oil to exporting carbon-neutral fuels and chemicals in 35 years.

 

So you don’t believe these fuels made from CO2 can compete with products from tar sands?

Take a look at where we see heavy oil going.

 
Why is 60% system net efficiency something to get excited about?

The bottom line beats any other renewable fuel by a very wide margin.

 
We see no other way. To cut CO2 emissions in half by mid-century we must have carbon-neutral transportation fuels that are cheaper than heavy oil products.
 
Storing very large amounts of energy in compressed air is 5,000 times more expensive than storing energy in liquid fuels.
 

So you don’t believe cellulosic ethanol will be over $5.00/gal by 2015?

Have you looked at the hyperinflation in wood pellets over the past three years?

 
Why aren’t you optimistic about nuclear fission, biofuels, coal-to-liquids, SBSP, fusion, hydrogen fuel cells, heavy oil, algae oil, and roof-top solar PV?

Take a look at our analyses. We stick with science and economics, and avoid the hype.
