Ammonia as a carbon-free hydrogen carrier for fuel cells: a perspective

Abstract

Driven by the growing need to decarbonize, hydrogen energy is considered a potential alternative to fossil fuels. However, due to the problems associated with energy storage and transportation for portable...

Chemical material as a hydrogen energy carrier: A review

“…Researches are actively exploring the utilization of methanol as a fuel synthesized from biomass, carbon-containing sources, including carbon dioxide, with the aim to enhance its economic viability. Figure 2 shows the carbon cycle utilization of methanol [30,39,[83][84]. The synthesis reactions of methanol are presented in Table 1 [26].…”

“…It also should consider the real data, which is collected from hydrogen commercial product, to evaluate direct and indirect effects [29]. However, hydrogen possesses a low volumetric storage density, posing a significant challenge in safely storing and transporting large quantities, crucial for transitioning to a hydrogen-based society that efficiently utilizes renewable energy [30][31][32][33][34][35][36][37][38][39]. While hydrogen utilization technology for fuel such as fuel cells has reached a commercially viable stage with secured infrastructure, efficient large-scale hydrogen storage technology necessitates extensive research and development efforts for commercialization [40][41][42][43][44][45].…”

The current status of hydrogen energy: an overview

“…for various use targets. 139,140 The goal is to provide green ammonia on a worldwide scale and have it break down into hydrogen at the point of use to provide hydrogen refueling stations. Direct ammonia fuel cells and other complementary technologies to extract the energy contained in green ammonia are required by the growing green ammonia sector.…”

Enhancing the Ammonia Catalytic Decomposition of Lanthanum Strontium Titanate Nickel Perovskite Catalysts via a Balanced Cation Doping and Deficiency Strategy

“…However, hydrogen storage, distribution, and transport are challenging due to the low density of hydrogen, requiring specialized infrastructure for compression and transport which limits its applications and availability in fueling stations, etc . To this end, ammonia has been recognized as a promising hydrogen carrier due to several advantages in the field of hydrogen energy, such as high capacity, − no CO x emissions, easy transport and storage, and high H 2 production selectivity; , therefore, it has drawn much attention. An ideal catalyst material for H 2 generation from NH 3 decomposition may possess (a) high activity, (b) long-term stability/good recyclability, (c) favorably low content of noble metal, and (d) realizing the potential of direct use of NH 3 to power fuel cells.…”
