Hydrogen is the energy carrier with highest density and critical to development of renewable energy. Efficient hydrogen storage essential realize transition sources. Electrochemical technology has a promising application due its mild conditions. However, research on most efficient electrochemical materials that satisfy goals U.S. Department Energy remain open questions. All above require strategies for designing new materials. This review provides brief overview preparation, storage, details We summarize capabilities alloys metal compounds, carbonaceous materials, oxides, mixed metal–organic frameworks, MXenes, polymer-based It was observed oxides exhibit superior discharge capacity cycling stability. The indicates it vital create novel large surface area, active-conductive profiles, low cost. describe challenges, gaps, future perspectives hope could draw more attention high capacity, safety, cycle stability, cost promoting their practical applications.

Hydrogen, a sustainable energy source, has potential to address climate change. However, traditional steam reforming processes produce CO2. Alternative fuels like bio-alcohols, biogas, and LPG are being adopted for processes. This study presents thermodynamic comparative examination of employing different fuels, including methane, methanol, ethanol, propane, glycerol, biogas. The analysis focuses on the hydrogen yield, environmental impact, requirements these comparison with experimental results. analyses were conducted using AspenPlus® software, minimizing Gibbs free under specified conditions (T = 25–1000 °C, n 1–10, P 1–40 bar). Among examined, methane exhibited highest yields, reaching maximum values 96.10 %, 95.86 95.26 % respectively at 600 1 bar, water-to-fuel ratio 10. Ethanol, propane achieved yields 89.66 86.55 84.03 700 °C same pressure ratio.

Liquid organic hydrogen carriers (LOHC) can be used as a lossless form of storage at ambient conditions. The cycle consists the exothermic hydrogenation hydrogen-lean molecule start transport, usually production site, becoming hydrogen-rich molecule. This loaded transported long distances or long-term due to its ability not lose over periods time. At site time required production, released through an endothermic dehydrogenation reaction. LOHCs show similar properties crude oils, such petroleum and diesel, allowing easy handling possibilities integration with current infrastructure. Using this background, paper reviews variety aspects LOHC life cycle, focus on currently studied materials. Important factors requirements for each material are analysed determine their in scenarios. Toluene dibenzyltoluene attractive options promising attributes, however enthalpies remain problem. economic feasibility being delivery device were briefly analysed. have been shown cheapest option distance transport (>200 km), cheaper than most shorter terms specifically costs. major capital cost chain remains initial investment raw materials equipment performing dehydrogenation. Finally, some studies developing field discussed, microwave enhancing parts process mixing acquire more advantageous properties.
