Green NH3 - Carbon Free Fuel


What is Green NH3?

Power + Green NH3 Synthesizer = Zero Emission Fuel for less cost than gas and diesel

Green NH3 is a patented fridge size machine that manufactures green sustainable ammonia (NH3) fuel from air and water at any location where fuel is needed in any quantity required, using clean renewable energy we have two proven green ways to make the fuel and three green ways to use it.

For 10+ years we’ve had the answer to carbon pollution.

The Goal

The Green NH3 goal is to manufacture 100 machines and sell them to large
scale farmers and mining companies

“We just want to build machines that are ready, and we can put them on a farm and go,”
said Gordon, Whom has received interest from not only local farmers, but mining
companies like Teck Resources, for their Polaris zinc mine in the Northwest Territories.

The ultimate goal is to provide Green NH3 Fuel to the everyday consumer to use in any of their combustible engines. From lawn mowers to jet planes.

Who is Roger Gordon?

Roger Gordon is the Inventor of Green NH3

Halton Hills inventor and pharmaceutical businessman Roger Gordon has developed a new technology to create carbon-free ammonia. 
After converting his Ford F350 to use the ammonia as fuel, Roger knew he had a viable option for clean renewable energy.
Using only nitrogen and hydrogen, Gordon creates a green ammonia that can be used as fuel for truck engines, farm equipment and even mining operations.
When burned as a fuel much like propane, Ammonia emits no carbon air pollution, only nitrogen and clean water.
He patented the technology back in 2014 and has since lobbied to get the government on board with his project.

Frequenting asked questions asked about Green NH3

Why use ammonia for a vehicle fuel?

Ammonia is one of the few practical liquid high-energy density non-petroleum fuels that we will ever have.

The laws of physics and chemistry limit the ways in which we can transfer energy efficiently.

Ammonia is one of the few chemical compounds which is a liquid, rapidly releases energy in combustion and has a high energy density by volume.

All of these parameters are needed for powering vehicles in a practical manner. And as wonderful added bonus, ammonia generates no greenhouse gases or carbon particulate emissions.

Where do you get ammonia?

Ammonia occurs naturally only in very small amounts.
Almost all ammonia is manufactured.

Most people are surprised to find out that ammonia is the 4th largest manufactured and transported commodity in the United States.

This is because ammonia is used for fertilizer for growing many of the foods here and around the world.
Because so much ammonia is used by farmers everywhere, ammonia is available almost everywhere.

Once GreenGas machines are mass produced everyone can produce their own Green NH3 fuel at their home or business or farm to be used for fuel and fertilizer.

Ammonia is produced naturally in the human body. When you get that sudden sting or sharp burst to cry in the nose and eye area, that is ammonia.

Green NH3 generates ammonia using clean power sources

Can ammonia be made from renewable or “green” energy sources?

This is one of the huge benefits of ammonia as a fuel.

You can’t make crude oil or gasoline at any price. When it’s gone, it’s gone forever.

But ammonia can be manufactured from any source of energy including great renewables like hydro-electric, solar or wind power. 

Also manufacturing ammonia does not involve shifting vast quantities of land from producing food to producing plants for biofuels.

Is ammonia a liquid or a gas?

Ammonia quickly turns to a gas when exposed to air.
But ammonia is easily and indefinitely stored as a liquid at about 150 PSI , a very low pressure which doesn’t require special high pressure tanks like hydrogen.

How does ammonia use compare to Hydrogen as a fuel?

has received a lot of press recently, it has several fundamental technical problems which will always dramatically limit its practical rollout for vehicular use on a broad scale.

These problems are not limited to the fact that hydrogen’s energy density is a tiny fraction of that of ammonia by volume. This means that you’d have to refuel your hydrogen vehicle as much as 7 times as often to go the same distance on hydrogen as you would using ammonia.

Hydrogen must also be stored at very high pressures (ie. 10,000 PSI), or at very low cryogenic temperatures. Both high pressure storage and cryogenic storage require significant additional power input, further reducing hydrogen’s energy efficiency.

In fact when we react ammonia, we’re actually using hydrogen, since that’s the element in ammonia that provides the energy.

How does ammonia use compare to natural gas?

Ammonia contains no carbon and releases no greenhouse gases, but natural gas does.

Although natural gas is somewhat cleaner than gasoline, its use still releases greenhouse gases in significant quantities.

One day natural gas will run out but ammonia can always be manufactured using a GreenGas synthesis machine.

What is needed to manufacture ammonia?

Ammonia can be made from air, water and a source of energy.

Nitrogen from the air, and hydrogen from the water, using a GreenGas synthesis machine

What are the emissions from a converted ammonia fueled vehicle?

he reacted ammonia are nitrogen and water vapor. When operated dual fuel, the gasoline or other hydrocarbon may still generate a small amount of CO and CO2, etc.

However, this emission is typically reduced by roughly 60 to 70%. If used in fuel cell the emissions drop to zero.

All fuels and energy sources, including even charged batteries have some potential hazard associated with them.

However, ammonia will not explode like gasoline, natural gas or hydrogen. In fact, it is difficult to get ammonia to burn, even though it makes an excellent fuel for cars and trucks.

Ammonia vehicle fueling and storage takes place safely without any human access to the ammonia liquid or gas, just like the fueling process for natural gas vehicles.

Also, ammonia does not represent a long term toxin to cellular biology, whereas gasoline is quite poisonous.

Ammonia is classified as a caustic substance, which means inhaling it or getting it on your skin isn’t healthy, but overall it is far less dangerous than gasoline.

Since ammonia (NH3) fuel can be created close to the point of refill fewer large tankers or railcars of fuel need to be moved around cutting down on danger from accident and polution and fuel used in the transport.

How does an ammonia dual fueled vehicle work?

The simplest implementation of the dual fueled ammonia vehicle conversion is physically similar to a compressed natural gas vehicle conversion.

A new on-board tank holds liquid ammonia at only about 150 PSI.

Regulators, valves and an electronic control system meter the flow of ammonia to the engine as needed after the engine is started and warmed up on gasoline, ethanol etc.

A small amount of gasoline is used to idle the engine, then as the load is increased the additional energy is provided by adding ammonia.

This is all handled automatically by the engine control electronic module.

Can I buy a conversion kit for my private car today


Not at this time.

Conversion work is currently concentrated with fleet vehicles and other large market applications.

Although, with increasing gasoline prices, conversions for private vehicles are coming.

How much will private vehicle conversion cost?

Conversion to operate substantially on ammonia is similar to the process of converting a vehicle to operate on compressed natural gas or propane.

The parts and labor are expected to be a couple of thousand dollars for private cars.

Of course if the vehicles were built to use ammonia (NH3) new at the factory (Our Ultimate Goal) it would cost much less.

We contacted all the auto companies in previous years but none have responded yet.

When is it cost effective to convert my car and operate on ammonia?energy sources?

Savings depend on the price of both gasoline and ammonia. 

During the NH3 car’s trip across America, gasoline was more than $2.25/gallon and ammonia was approximately $450/ton.

This scenario represented a cost savings over operating on straight gasoline.

Currently gas prices are fluctuating wildly, but one thing is for sure, in the future we can all expect increasing petroleum prices.

Can my converted car still be operated on just gasoline?

Yes, with the flip a switch the vehicle can run on 100% gasoline as normal.

Something not possible with many natural gas vehicles.

How big is the ammonia tank?

Ammonia when liquefied contains roughly half of the energy of gasoline by volume.

This means that an ammonia tank the size of your current gas tank will carry you more than 2/3rds of the distance of operating on gasoline alone, between fill ups when the contribution of the gasoline’s energy is considered.

Developments of Green NH3 – Ammonia

History of NH3 fuel

“The search for the “ideal” alternative fuel to eliminate US addiction to imported petroleum has been a long, difficult trek.

An early utilization of liquid NH3 as a fuel for motor-buses took place in Belgium during 1943. Emeric Kroch developed these ammonia / coal gas hybrid motors to keep public transportation in operation despite the extreme diesel shortages of World War II. “

Japanese professor Shinji Kamihara develops device to allow cars to cleanly run on hydrogen from ammonia

“The Plasma Membrane Reactor can take a jug of ammonia and convert it into pure hydrogen cleanly and cheaply to power anything from portable generators to cars”

Ammonia powered car

“Marangoni – the Italian tire manufacturer – used the most recent Geneva Motor Show to reveal a special version of Toyota’s nimble sports coupe. The GT86-R Eco Explorer”

“The ‘Eco’ comes in when we tell you that the car is actually fitted with a Bigas International NH3 system, which means that the engine can run on ammonia – that’s right, ammonia – which is stored in a separate tank.

According to Marangoni, considering that a litre of ammonia costs just 20 cents and the 30-liter tank means a range of 180km.

When the engine works at 2,800 rpm it can be fuelled exclusively on ammonia alone, “

Your Car Might Soon Be Able To Run On Ammonia

“The Ammonia catalyst that will be used in automobiles will be as big as a 2-litre Soda bottle. It will produce enough hydrogen to power a family car.

Ammonia is not expensive and is available in plenty. It can be filled into the tanks with our existing fuel pumps. This makes it the biggest possibility that Ammonia could power the future cars.”

Hydrogen breakthrough could be a game-changer for the future of car fuels

“David Willetts, the UK Minister for Universities and Science, said “This is exactly the sort of innovation we need UK researchers and engineers to develop to secure our role as a global leader in this field, putting Britain at the forefront of solving modern day transportation problems.

This breakthrough could also hugely contribute to our efforts to reduce our greenhouse gases by 80% by 2050.”

Farming with Ammonia

It’s the most efficient and thus most environmentally friendly choice.

Farmers use ammonia to obtain the element nitrogen. Ammonia is stored in its liquid form in a pressure tank at about 100 pounds per square inch, until it’s injected under the soil from a tank pulled by a tractor, carefully controlled by an intricate system of valves and meters according to the calculated requirements of the crop. As the ammonia is released from the pressurized tank into the distribution system, the sudden drop in pressure causes it to boil, releasing the elemental nitrogen that can be immediately used by fast-growing plants that demand a large supply of nitrogen.

Research shows nitrogen supplied as ammonia is used by crops as effectively as nitrogen from any other source. In fact, according to one estimate, to maintain soil fertility without such man-made sources of nitrogen, the 11 million tons of industrially created nitrogen that US farmers use each year, much of it supplied as ammonia, would have to be replaced by manure from approximately 1 billion additional cattle. Those cattle would require another 2 billion acres to feed. That feed demand would take roughly the entire continental United States.

X-15 A-2

The X-15A-2 burns a volatile mixture of ammonia and liquid oxygen as fuel. When ignited, its single XLR 99 engine burns 7 tons of fuel in just over a minute and generates half a million horsepower, nearly 60,000 pounds of thrust. By comparison a modern day F-16 fighter generates about 30,000 pounds of thrust in full afterburner.

It flew at nearly Mach 7, seven times the speed of sound and twice the speed of a rifle bullet. The speed record it set 47 years ago today still stands today.

America’s transition to renewable energy faces a huge challenge. Oil shortages, pollution and the cost of gasoline make our continued reliance on the internal combustion engine problematic, and electric cars just don’t have the range to be a viable option for everyone. The NH3 Car is designed to meet that challenge. NH3 (which is the chemical name for ammonia) can be used as a fuel. It is 100% free of any carbon emissions or other greenhouse gases. NH3 can serve as a fuel in both spark ignition engines (vehicles powered by gasoline) and compression ignited engines (vehicles powered by diesel). We focus on spark ignition (gasoline) engines. (Other design teams are working on using ammonia for diesel engines. You can find those folks on our links page.)

This web site is designed to keep you up to date on the progress of the NH3 Car. After years of development, in the summer of 2007 we drove our NH3 vehicle across America, from Detroit to San Francisco, powered by a mix of ammonia and gasoline. (OK, well it is really a truck, but it could just as easily be a car in the future.) Why a mixture….how does it work….what does this mean for America’s energy future?
