A Canadian technology firm claims it has made equipment that will make zero-emissions eco-friendly ammonia from renewable hydrogen at a significantly much less expensive price than remarkably polluting grey ammonia.
About 235 million tonnes of ammonia (NH3) are manufactured globally each and every year, mostly for fertiliser, nearly all of which is created by combining grey hydrogen — derived from natural fuel or coal with carbon emissions of nine to 18 tonnes for every tonne of H2 — with nitrogen from the air in a century-aged method known as Haber-Bosch.
Haber-Bosch is very electrical power-intensive — necessitating superior temperatures of 400-500°C and pressures above 100 bar — and is usually powered by burning fossil fuels. This procedure by itself is stated to be dependable for 1% of the world’s carbon emissions each and every calendar year — and that’s not like the CO2 emitted from gray hydrogen manufacturing.
And with about fifty percent of the world’s food stuff output relying on ammonia fertiliser, decarbonising the generation of the chemical is of critical relevance — not to mention the point that environmentally friendly NH3 is becoming touted as a opportunity carbon-free of charge gasoline for shipping and even electricity creation.
This is in which Toronto-dependent FuelPositive will come in.
It states it can develop inexperienced ammonia from water, air and electrical power at a more cost-effective selling price than the grey ammonia on sale today — and do so at nearly any site on Earth.

FuelPositive will mix electrolysers (which split h2o molecules into hydrogen and oxygen) with a proprietary reactor that brings together nitrogen from the air with H2 making use of “much decrease temperatures and substantially decrease pressure” than Haber-Bosch, ensuing in 40% decrease charges.
And because this modular “hydrogen ammonia synthesiser” procedure will be marketed inside of plug-and-engage in shipping-container-sized containers, they can be installed any where that ammonia is essential — getting rid of transport fees of NH3, which can account for 50% of the cost of gray ammonia.
Employing a case examine of a 1,800-acre farm in Manitoba, Canada, FuelPositive says it can offer the expected ammonia for about C$560 ($443) for each tonne, compared to an common price tag in 2021 of C$900 — a 37.7% price reduction. This output value is dependent on a electrical power price of C$45/MWh employing Manitoba’s 99.8% hydro-run electrical power grid.
FuelPositive expects foreseeable future creation efficiencies to bring the running expense down to underneath C$500 for every tonne, incorporating that additional price reductions could arrive from carbon offsets, as every tonne of environmentally friendly NH3 replaces four tonnes of CO2.
The FuelPositive method would also offer farmers with independence from “the wildly fluctuating offer chain that exists now for grey anhydrous ammonia”, the enterprise reported, pointing to the point that the value of NH3 in Manitoba doubled from C$600 for each tonne to C$1,200 in a six-thirty day period interval this year.
FuelPositive main govt Ian Clifford states the patent on its ammonia synthesiser is however pending, so he can not expose much too substantially depth about how it functions, only to say that it uses a various cascading reactor system.
If the electrical energy utilized for the process is renewable, the whole procedure will be emission-absolutely free, with the only output currently being chilly liquid ammonia — which farmers globally commonly use to grow grains and pulses — he tells Recharge.
“Considering that corn and wheat and a whole lot of pulses are accountable for feeding most of the planet, it is a huge current market, and it is normally fossil gas that is utilised for that. So we expect that our original demonstrations will be focusing on farmers who have that form of a mix,” he claims, introducing that most of these farmers will currently retail store ammonia on their farms.
“One of the fantastic things about farming is there’s normally a large amount of true estate associated, so if you wanted to established up your individual solar or wind or micro-hydro [power plant], you can do that and just plug the system in.
“And if you’re a farmer in Manitoba, for example, 99.8% of the energy in Manitoba is hydroelectric. So you can plug immediately into the grid in Manitoba and produce carbon-absolutely free ammonia for your procedure.”
A single electrolysis technology FuelPositive is assessing ideal now are anion-trade membrane (AEM) electrolysers developed by Italian maker Enapter, which do not involve the purified H2O ordinarily essential for electrolysis — as an alternative, very simple faucet h2o can be utilised. And that electrolyser could even be modified to use seawater, Clifford provides.
A even further reward is that the grain-drying procedure — which is commonly driven by propane or organic gas — can in its place be fuelled by burning ammonia, even further decreasing costs and CO2 emissions (even though combusting NH3 would release a fair amount of money of nitrous oxide, alone a potent greenhouse gas).
“This is a large, large customer of energy and not a ton of persons are conscious of it,” Clifford describes.
FuelPositive built its initially full-size prototype system in June, and is thanks to construct a second and 3rd prototype by the end of the year, employing a batch-model strategy to production.The first complete pilot technique will be ready to deploy subsequent summer months, with serial production expected to begin in 2023.
The FuelPositive technologies — if it lives up to the claims — has the potential to revolutionise the international ammonia business.
Only this morning [Thursday], German believe-tank Agora Energiewende introduced a hydrogen report that stated it would be much less expensive for European businesses to import inexperienced ammonia from the likes of Argentina, South Africa and Australia than create it them selves — but that report assumed the use of the much more-highly-priced Haber-Bosch process.
Chief functioning officer Nelson Leite is presently generating comparisons to the disruption that Elon Musk’s Tesla has brought to the auto sector.
“We have established an aggressive timeline. We are impressed, in element, by Tesla’s excellent success with its solution to manufacturing and solution enhancement. With a solution not very as intricate to manufacture or as controlled as an electric powered motor vehicle, FuelPositive absolutely intends to abide by Tesla’s direct and set a new common for our business,” he states.
