With international shipping activity to more than double by 2050, the IEA forecasts that ammonia’s share of final energy consumption in the industry will rise to 44% in 2050, with a suite of other low-carbon fuels to play smaller roles. Lloyd’s Register & OCI HyFuels have also forecast that ammonia (and particularly electrolytic ammonia) will become the most significant fuel in the maritime sector by 2050.
Anion Exchange Membrane (AEM) electrolysis combines concepts from alkaline and PEM. Although AEM can potentially offer the best of both worlds compared to conventional technology, challenges such as oxygen sensitivity, stack scale-up and current density still need to be addressed. Germany-based Enapter is leading the commercialization of AEM systems, with other electrolyzer manufacturers now developing their own products.
Hydrogen Certification 101, the Hydrogen Council’s new report, provides a helpful summary of key certification terminology and concepts. It is the latest report to advocate for mutual recognition as a solution to inconsistency in energy policy, while also delving into practical measures to support the fundamental design principles of certification schemes.
Alkaline electrolyzers will play a significant role in renewable ammonia production going forward. Historical developments in electrocatalysts and optimized stack design have already addressed some of the key bottlenecks in the technology, and new developments will enable flexible operations at higher pressures.
