The Ammogen project installs an ammonia-to-hydrogen cracker with H2SITE patented technology.

The Ammogen consortium has reached another project milestone with the installation of its ammonia storage and vaporisation system at the Tyseley Energy Park in Birmingham.

H2SITE has supplied the project with its patented ammonia cracking technology, based on a unique palladium membrane capable of producing pure hydrogen for fuel cells in a single step, using a modular containerised reactor. In the Ammogen project, H2SITE is collaborating with Yara, which is supplying it with low carbon ammonia to produce pure hydrogen ready to power a fleet of 20 fuel cell buses for the city of Birmingham. Once commissioned, the project will deliver up to 200 kg of transport-grade hydrogen per day.

The system consists of two units, a vaporisation system and an ammonia drum decant that will convert seven tonnes of ammonia into fuel cell quality hydrogen. The ammonia vaporiser has a carbon steel storage vessel that stores and separates liquid and vapour ammonia before it is fed into the cracking process. The vessel also collects and removes the water present in the ammonia.

The second unit has three ammonia supply valve stations for positioning 530 kg drums of ammonia. The framework includes load cells to measure the mass of the drum and ammonia as it is transferred to the storage vessel. Each ammonia drum has an individual heater-mounted duct to circulate warm air over the drum to pressurise the gas and transfer it to the ammonia storage vessel.
