Hydrogen is considered as a promising fuel in the 21st century due to zero tailpipe CO2 emissions from hydrogen-powered vehicles. The use of hydrogen vehicles can play an important role decarbonising transport sector and achieving net-zero targets. However, there exist several issues related production, efficient storage system refuelling infrastructure, where current research focussing on. This study critically reviews analyses recent technological advancements distribution technologies along with their cost associated greenhouse gas emissions. paper also comprehensively discusses methods, identifies fast explores control strategies. Additionally, it explains various standard protocols relation safe refuelling, economic aspects presents infrastructure. suggests that production significantly varies one technology others. fossil sources using most established were estimated at about $0.8–$3.5/kg H2, depending on country production. underground exhibited lowest cost, followed by compressed liquid storage. levelised station was reported be $1.5–$8/kg station's capacity country. Using portable stations identified option many countries for small fleet size low-to-medium duty Following progresses, this end knowledge gaps thereby future directions.

The aim of this work is the preparation and electrification Ni_CeO2_Al2O3/OBSiC (Oxygen Bonded SIlicon Carbide) based foams used in two different endothermic reactions for H2 production: methane steam reforming ammonia cracking. In particular, heating catalytic occurs by Joule effect, to guarantee a uniform temperature profile both axial radial direction, resistances were used. addition, high tortuosity together with very thermal conductivity OBSIC carrier, allow overcome heat mass transfer limitations achieving better control reaction behavior. Wet impregnation method was adopted Ni Ce deposition, while final catalysts characterized through Hg penetration technique, Scanning Electron Microscope (SEM), N2 adsorption @77 K specific surface areas (SSA) determination X-ray diffraction (XRD). cracking tests carried out, same reactor, but at space velocity values (WHSV). results obtained are exciting, not only terms equilibrium approach hydrogen production, also energy consumption as kWh/Nm3 produced. case showed an E [kWh/Nm3 H2] equal 1.21 WHSV 6.2 h−1, close theoretical limit 0.98 kW h/Nm3 H2. Also, cracking, promising considering scale our 1.5 2.27 0.71

This study investigates the effectiveness of catalytic decomposition methane for producing turquoise hydrogen and solid carbon nanomaterials. The focus is on developing cost-effective high-performance Nickel (Ni)-promoted perovskite oxide catalysts. A series transition metal, Ni-promoted (La0.75Ca0.25)(Cr0.5Mn0.5)O3-δ (LCCM) catalysts have been successfully prepared using water-based gel-casting technology. These are designed to decompose into nanomaterials, achieving negligible CO2 emissions. X-ray diffraction results indicate that solubility Ni at B-site LCCM limited, x ≤ 0.2. Field Emission Scanning Electron Microscopy analysis xNi-LCCM, calcined 1050 °C ten h in air, confirms severe catalyst sintering with excess nickel distributed around particles. At a 750 operating temperature, molar ratio 1.5 yields maximum output 17.04 gC/gNi. Increasing ratios 2.0 2.5 17.17 gC/gNi 17.63 gC/gNi, respectively, showing minor changes. morphology nanomaterials unaffected by NiO promoter remains nearly same within scope this study.

The supply of the heat required for chemical processes via renewable electricity, i.e., process electrification, provides an alternative strategy replacing conventional fossil fuel combustion. This approach enables fast, selective, and uniform heating, offers great potential utilizing excess electric energy, brings about important chance mitigating CO2 emissions. In this work, we provide overview state-of-the-art electricity-to-heat driven catalytic processes. principle fundamentals Joule heating are provided briefly compared to induction microwave in view electrifying By comparison, assess that can be regarded as most promising method its applications methane reforming, cracking reactions, valorization, transient operation then reviewed. Advantages disadvantages critically addressed terms efficiency, scale-up possibility retrofitting. current challenges development advanced electrified well opportunities next generation electrification techniques discussed.
