    For hydrogen to become a direct, portable fuel source, the difficulties with its storage and subsequent release must be addressed. Here ethylene glycol is shown to act as an efficient, reversible liquid-to-liquid hydrogen carrier—particularly attractive due to its theoretical H2 capacity of 6.5 wt%.

    Considering the large number of existing synthesised and hypothesised metal-organic frameworks, determining which materials perform best for given applications remains a challenge. Here, the authors screen the usable hydrogen uptake capacities of nearly 500,000 MOFs, and find that three frameworks outperform the current record-holder.

    Renewable hydrogen technologies are promising for alternative energy, but are encumbered by the kinetics of electrochemical reactions in harsh conditions. Here, authors report nitrogen-modified hafnium oxyhydroxide for electrocatalysis of hydrogen evolution and oxidation reactions in acidic media.

    While water-splitting electrocatalysts enable energy storage in carbon-neutral fuels, a recent challenge has been the discovery and understanding of catalyst active sites. Here, authors find domain boundaries in MoS2 materials to present high-activity, stable, and scalable sites for H2 evolution.

    Reversible electrochemical cells can operate in both fuel cell and electrolysis modes to interconvert between chemical and electrical energy. Here, Duan et al. design a reversible protonic ceramic electrochemical cell that operates stably at 500–600 °C, with high Faradaic and round-trip efficiencies, by minimizing electronic leakage.

    Scalable interconversion between chemical and electrical energy requires compact, selective and highly efficient reversible electrochemical cells. Now, protonic electrochemical cells with tailored catalysts and ceramic architecture are shown to operate reversibly with high performance and to be integrable with catalytic CO2 conversion.

    Ammonia holds promise as a clean energy carrier, but its synthesis requires high pressures and large production scales that are ill-matched to renewable, decentralized energy production. Now, researchers use metal imides to mediate ammonia production in a chemical looping process that operates under mild conditions.

    Semi-artificial photosynthesis offers advantages over purely natural or synthetic routes to producing chemicals from solar energy, but devices based on it have remained elusive. Now, researchers couple a dye-sensitized photoanode with natural components to generate H2 photoelectrochemically from water without additional bias.

    Development of an earth-abundant and inexpensive copper-based catalyst is desirable for CO2 hydrogenation. Now, the combined application of a stable copper hydride and a Lewis pair is shown to effect activation of CO2 as well as heterolysis of H2, achieving significant turnover numbers.

    Photocatalytic water splitting is a route to clean H2, but approaches based on hybrid semiconductor–metal nanoparticles often rely on sacrificial reagents to complete the oxidation half of the overall reaction. New research uses CdS nanocrystals modified with metallic and molecular co-catalysts to simultaneously produce H2 and O2 from water using visible light.

    Various approaches have been adopted to enhance the performance of alkaline water electrolysers, such as improving catalyst efficiency or increasing operating temperatures. Now, magnetic hyperthermia is demonstrated as another potential route to enhance overall water splitting catalytic activity.
