AFC Energy’s next-generation ammonia cracker technology has successfully achieved 99.99% hydrogen from single reactor testing, meeting international standards for fuel cell applications, new test results show.
AFC Energy shares were 4% higher at the time of writing on Monday.
Independent analysis by the UK’s National Physical Laboratory confirmed the hydrogen derived from AFC Energy’s ammonia cracker and purifier contains ammonia at levels below limits in the ISO 14687:2019 standard for fuel cell grade hydrogen.
The results highlight AFC Energy’s ammonia cracking technology can deliver fuel cell grade hydrogen on a modular, scalable basis.
The ability to meet the ISO standard for residual ammonia “parts per billion” in hydrogen is a key milestone for the cracker technology. It demonstrates potential to support growing “ammonia to power” uses in stationary and maritime applications.
Cracking ammonia into hydrogen also enables use for refueling heavy duty hydrogen fuel cell vehicles. This provides an alternative to small scale electrolysis for distributed hydrogen production.
The ammonia cracker converts ammonia into discrete hydrogen and nitrogen molecules. The trace ammonia presence can damage fuel cells if not removed.
Meeting the ISO standard was tested based on individual ammonia cracker reactors. Independent analysis by the UK’s National Physical Laboratory confirmed the residual ammonia results.
