Amogy ($219M to develop ammonia-to-hydrogen energy system for transportation decarbonization)

Amogy, an American cleantech company founded in 2020, develops an integrated fuel cell system that enables the decarbonization of hard-to-abate sectors such as shipping, power generation, and heavy-duty transportation. The system uses liquid ammonia as a source material, cracks ammonia into hydrogen energy source, and uses hydrogen fuel cells to provide electric power to various transport carriers, including drones, automobiles, tractors, trucks, marines, and even airplanes.

Challenges: e-mobility with fuel cell

Hydrogen gas (H₂) can be used as a source of clean energy for a variety of applications. It has a distinct advantage over other fuels such as diesel, gasoline, and jet fuel, which have a specific energy of about 45 MJ/kg, and lithium-ion batteries, which have a specific energy of about 0.95 MJ/kg. In contrast, hydrogen has a specific energy of over 140 MJ/kg, which means that 1 kg of hydrogen is equivalent to 3 kg of gasoline or kerosene. This can help reduce the amount of fuel required to produce the same amount of energy. Additionally, hydrogen-powered systems typically produce only water as a byproduct and have minimal or no greenhouse gas emissions, minimizing their environmental impact.

95% of the world's hydrogen (over 60 million tons) is currently produced by steam methane reforming (SMR) process, which requires substantial energy input and emits a significant amount of CO₂. In addition, hydrogen produced at industrial SMR plants must travel a great distance to reach its users. Hydrogen transportation involves either pressurizing the hydrogen gas or cryogenically cooling the hydrogen gas to -253 ºC to create liquid hydrogen. The International Energy Agency estimates that the costs of hydrogen transportation could be three times that of its production.

Amogy Technology

Amogy has developed an integrated energy system that uses liquid ammonia (NH₃) as a source material, decomposes NH₃ into hydrogen energy source, and uses hydrogen fuel cells to generate high electrical power of at least 5 kilowatts with a high energy density of at least 655 Wh/kg or 447 Wh/L. The energy system can power transport carriers from small drones to marines, enabling the decarbonization of commercial transportation.
