Article Abstract

The advantages of ammonia as a hydrogen carrier have led to proposals for on-site hydrogen production through its decomposition. Rapid cold start of ammonia decomposition is crucial for applications such as ammonia-powered vehicles, but conventional heating methods are challenged by the high decomposition temperature of ammonia. In this study, we successfully achieved the rapid cold start of ammonia decomposition using Co nanoparticle catalysts driven by magnetic induction heating, demonstrating excellent catalytic performance and stability. The magnetic induction heating-driven ammonia decomposition system was integrated with a hydrogen fuel cell, proving its ability to achieve the cold start of ammonia decomposition within 10 s, as demonstrated by comparative experiments using 75% H-25% N from a gas cylinder as the control. This study provides a deeper understanding of hysteresis heating catalysis, promoting the practical use of ammonia as a hydrogen carrier for rapid hydrogen production in the energy industry.

In this paper, a concept of integrated CO capture and reverse water-gas shift (ICCrWGS) process was proposed using NH as the H carrier. The CO efficiency and total thermal energy consumption for the conventional rWGS, ICCrWGS using H (H-ICCrWGS) and NH (NH-ICCrWGS), were calculated. ICCrWGS using H and NH was conducted over the thermally stable Ni/CaZr dual-function materials (DFMs).

Ammonia (NH), as a hydrogen energy carrier, is advantageous for mitigating energy consumption and carbon emission; however, the current Haber process for NH synthesis requires harsh conditions with a low conversion rate. To address these challenges, chemical looping ammonia synthesis (CLAS) has been proposed for utilizing aluminum dross (AD)-a hazardous waste containing sufficient active Al and N as a nitrogen carrier-involving carbon conversion without emissions. AD samples were employed to investigate the performance of CLAS, and the evolution of nitrogen carrier.
