A Canadian know-how agency says it has developed gear Which will produce zero-emissions inexperienced ammonia from renewable hydrogen at a far cheaper worth than extremely polluting grey ammonia.
About 235 million tonnes of ammonia (NH3) are produced globally Yearly, primarily for fertiliser, virtually all of which is produced by combining grey hydrogen — derived from pure gasoline or coal with automotivebon emissions of 9 to 18 tonnes For every tonne of H2 — with nitrogen from the air in a century-previous course of referred to as Haber-Bosch.
Haber-Bosch is terribly power-intensive — requiring extreme temperatures of 400-500°C and strains above 100 bar — and Is usually powered by burning fossil gasolines. This course of alone Is claimed to be Responsible for 1% of the world’s automotivebon emissions Yearly — and that’s not collectively with the CO2 emitted from grey hydrogen manufacturing.
And with about half of the world’s meals manufacturing Counting on ammonia fertiliser, deautomotivebonising the manufacturing of the chemical is Of important significance — To not level out The fact that inexperienced NH3 is being touted as A potential automotivebon-free gasoline for delivery and even power manufacturing.
That is the place Toronto-based mostly FuelPositive Is out there in.
It says It might produce inexperienced ammonia from water, air and Electricity at A much less costly worth than the grey ammonia on sale right now — and Obtain this at virtually any location on Earth.

FuelPositive will mix electrolysers (which Chop up water molecules into hydrogen and oxygen) with a proprietary reactor That mixes nitrogen from the air with H2 using “a lot decrease temperatures And a lot decrease strain” than Haber-Bosch, Ensuing in 40% decrease prices.
And since this modular “hydrogen ammonia synthesiser” system Shall be purchased inside plug-and-play delivery-container-measurementd bins, They’re typically put in anythe place that ammonia is required — eliminating transport prices of NH3, Which might account for 50% of The worth of grey ammonia.
Using a case research of a 1,800-acre farm in Manitoba, Canada, FuelPositive says It might current the required ammonia for about C$560 ($443) per tonne, As in contrast with A imply value in 2021 of C$900 — a 37.7% low cost. This manufacturing value Is predicated on An affect worth of C$45/MWh using Manitoba’s 99.8% hydro-powered Electricity grid.
FuelPositive anticipates future manufacturing efficiencies to convey the working value Proper down to beneath C$500 per tonne, including that further worth reductions might come from automotivebon offsets, as every tonne of inexperienced NH3 replaces 4 tonnes of CO2.
The FuelPositive system would furtherly current farmers with independence from “the wildly fluctuating current chain that exists right now for grey anhydrous ammonia”, The agency said, leveling to The fact that The worth of NH3 in Manitoba doubled from C$600 per tonne to C$1,200 in a six-month interval this yr.
FuelPositive chief authorities Ian Clifford says the patent on its ammonia synthesiser Continues to be pending, so he can’t reveal An extreme quantity of element Regarding the biggest method It exactly works, solely to say that it …….
