Ammonia is emerging as a key hydrogen carrier in the global low-carbon energy landscape. Efficient and flexible ammonia cracking is critical to unlocking its potential for on-demand hydrogen production. Plasma-based ammonia cracking offers a transformative pathway, leveraging non-equilibrium activation under mild conditions for rapid response and direct integration with intermittent renewable electricity. This approach provides a flexible and distributed solution for hydrogen generation, supporting a resilient and sustainable energy infrastructure. This presentation will discuss the economic potential of plasma-based ammonia cracking, focusing on hydrogen production cost, system scalability, and integration with renewable energy, highlighting opportunities for a viable and sustainable hydrogen economy.
