ACT - Evaluation of Catalysts for Ammonia Cracking into Hydrogen

Ammonia is gaining interest as an energy carrier for mobility due to its high hydrogen content and ease of storage and transport. Neology, a young company, focuses on developing solutions using ammonia especially for mobility applications.

The thermo-conversion of ammonia into hydrogen and nitrogen occurs at temperatures above 900°C. To reduce this temperature, and therefore the energy required, catalysts are used. Producing pure hydrogen for PEMFC (Proton Exchange Membrane Fuel Cells) remains a challenge.

The project focused on testing catalysts with a reactor towards the development of an "on-board" demonstrator with a PEMFC.

Technical goals involved testing selected catalyst, conducting preliminary validation in a simplified reactor, and measuring catalyst stability according to Neology's specifications. These objectives were continuously refined throughout the project.

Testing was conducted on a dedicated test bench, which was modified multiple times based on the experimental results.

Deliverables produced by the end of the project include conversion rate measurements, a PLC Beckhoff program for the test bench, and detailed feedback on equipment used. Detailed aging tests on the catalysts could not be performed due to time constraints.

The project faced it share of challenges in resource management and technical incidents. Reactor supply issues caused interruptions. Safety concerns regarding ammonia usage were prioritized.

Despite obstacles, Neology remained flexible, adapting to changing expectations and strategies. Neology also pursued the development of demonstrators in collaboration with HEIG-VD. The project facilitated technology transfer, with Neology receiving recognition, including the Venture Kick award, and demonstrating a small truck, a Goupil vehicle, converting ammonia to hydrogen to power a PEMFC in May 2024.
