The storage and transfer of energy require a safe technology to mitigate the global environmental issues resulting from massive application fossil fuels. Fuel cells have used hydrogen as clean efficient source. Nevertheless, transport presented longstanding problems. Recently, liquid organic carriers (LOHCs) emerged solution these issues. technique in LOHCs is more attractive than those conventional systems like liquefaction, compression at high pressure, methods adsorption absorption. release acceptance should be reversible by LOHC molecules following favourable reaction kinetics. comprise semi-liquid compounds that are hydrogenated store hydrogen. These stored transported finally dehydrogenated required for supplying energy. Hydrogenation dehydrogenation conducted catalytically multiple cycles. This review elaborates on characteristics different molecules, based their efficacy generators. Additionally, catalysts both hydrogenation discussed.

This study assesses the competitiveness of producing green hydrogen (H2) in Saudi Arabia and Germany using a power-to-carrier (P2X) model PLEXOS for 2030 beyond. The target amount H2 to be produced serves as only exogenous input, allowing model, which runs on an hourly temporal resolution, endogenously optimize electrolyzer technology (alkaline, proton exchange membrane, or solid oxide cell), capacity built, optimal carbon-free energy mix. Results suggest overall investment needs are approximately 25% lower than those wind-based production Germany, with best-case scenario produce 0.213 Mt costing net present value $6.20 billion Arabia, compared $8.11 Germany. findings indicate that alkaline electrolyzers dominate process, favored their low cost despite higher efficiencies other types. Moreover, opts dump excess rather construct battery storage. Based 16 scenarios, determines levelized 2.34–3.08 $/kg 3.06–3.69 Subsequently, detailed sensitivity analysis considers various discount rates both countries. It is concluded even when considering shipment costs from (∼1 $/kg), can still competitively delivered

In the context of near-future hydrogen economy, ammonia is regarded as one most promising carriers in short-to-medium term. As part broader transition to a new energy paradigm, well-established and extensive infrastructure can serve platform for green transportation, storage, utilization. This study analyzes various process configurations integrated with different types fuel cells utilization through Aspen Plus simulations. The evaluation focuses on overall energetic efficiency (ranging from 31.20 51.50% depending adopted configuration), autothermality (42.00 100.00%, based emissions external heat sources (0.03–0.07 kgCO2/kWh). Assessments are conducted parametrically across cell efficiencies (50.0–65.0%). Results suggest that high-temperature PEMFC direct solid oxide (SOFCs) offer balance between (40.2–51.5 35.00–52.0%, respectively) feasibility achieving autothermal operations under nitrogen dilution (up 25.0%). Considering technological maturity operational lifespan, PEMFCs SOFCs emerge component such systems.
