Top 13 Ammonia Fuel startups

Updated: Feb 27, 2026

These startups develop ammonia synthesis methods, fuel cells and combustion engines optimized for ammonia combustion.
1
Neology
Country: Switzerland | Funding: $3M
Neology is developing a system that converts liquid ammonia into hydrogen and then into electricity using fuelcells, with water being the primary byproduct. The process involves an "ammonia cracker"- a device that splits ammonia into hydrogen and nitrogen. The hydrogen is then fed into a fuelcells to generate electricity, while nitrogen, a harmless component of air, is released. The technology is designed for applications where battery-electric solutions may be ineffective, particularly for heavier vehicles, long-term operation, or in low-temperature environments. The resulting hydrogen can also be used in a variety of other ways.

Addis Energy
Country: USA | Funding: $17.1M
Addis Energy has developed a new technology for producing ammonia fuel for marine and industrial electricity generation. It first locates underground rocks rich in iron, then injects water, nitrogen and chemical catalyst into these rocks. This causes the oxygen in the water to bond with the iron in the rocks, forming rust and releasing hydrogen, which reacts with the nitrogen to form ammonia. The advantage of this process is that once the startup can implement this reaction on a large scale, ammonia production will be three times cheaper than the traditional process, which requires natural gas subjected to high temperatures and pressures. Besides, Addis' technology is clean, while the traditional ammonia production relies on a fossil fuel dependent chemical reaction called the Haber-Bosch process, which accounts for nearly 2% of carbon emissions annually.

Monolith
Country: USA | Funding: $364.3M
Monolith is a next-generation clean materials company that uses a proprietary process to produce clean hydrogen, carbon black and ammonia.
4
Amogy
Country: USA | Funding: $355.3M
Amogy builds an innovative clean energy system using ammonia as a renewable fuel
5
Graphitic Energy
Country: USA | Funding: $63M
Graphitic Energy is developing a technology that converts natural gas to hydrogen, a much cleaner source of fuel, and solid carbon as the only waste stream for use in electrical generation, process heating and the production of commodity chemicals like hydrogen and ammonia.
6
Clean Hydrogen Works
Country: USA | Funding: $30M
Clean Hydrogen Works is providing safe, responsible, and innovative clean energy solutions for a carbon-free world (building hydrogen-ammonia plant).
7
FuelPositive
Country: Canada | Funding: CA$19.3M
FuelPositive is a technology company committed to providing commercially viable and sustainable, “cradle to cradle”, clean energy solutions, including an onsite, containerized Green Ammonia production system, for use across a broad spectrum of industries and applications.
8
Hgen
Country: USA | Funding: $7M
Hgen aims to decarbonize hard-to-crack industries like steel and ammonia production by focusing on green hydrogen that’s made using renewable power.
9
NitroVolt
Country: Denmark | Funding: $4.5M
NitroVolt is a green ammonia startup developing a small-scale ammonia synthesis unit, to give farmers control over fertilizer production.
10
NitroFix
Country: Israel | Funding: $3.6M
NitroFix aims to lower the global carbon footprint by generating ammonia with no carbon emissions.
11
Atmonia
Country: Iceland | Funding: $770K
Nitrogen electrolyser for direct sustainable ammonia produciton
12
Pancopia
Country: USA
Pancopia is developing a system to reduce ammonia levels in swine wastewater used as a biogas feedstock to levels that do not adversely affect swine productivity, and eliminates off-site nuisance ammonia odors.
13
Plastic 2 Green
Country: USA
Plastic 2 Green develops technology that allows to convert any plastic waste into two essential products: Ammonia for fertilizer or hydrogen fuel, and Carbon Nanotubes for superconducting wire or super capacitors.
