    Hydrogen is mainly produced industrially via steam methane reforming, a multistage process carried out in large plants to minimize energy losses and costs. Here, by exploiting thermal integration in a protonic membrane reformer, the authors produce compressed hydrogen in a single step with high efficiency.

    For proton-conducting metal–organic frameworks (MOFs) to find application as the electrolyte in proton-exchange membrane fuel cells, materials with better stability and conductivity are required. Now, a structurally flexible MOF that is also highly stable is demonstrated to possess high proton conductivity over a range of humidities.

    Kesterite solar cells are low-cost alternatives for photovoltaics, based only on abundant metals, but they exhibit limited voltages. A new wide-gap kesterite solar cell provides a much higher voltage at a good efficiency.

    Understanding how subsidies affect fossil-fuel investment returns and production is crucial to commencing new reforms. New analysis on the impact of subsidies on US crude-oil producers finds that, at recent oil prices of around US$50 per barrel, tax preferences and other subsidies push nearly half of new oil investments into profitability.

    Proton-conducting metal-organic frameworks (MOFs) could be used as the electrolytes in proton exchange membrane fuel cells but chemically stable materials that perform well at low humidity are still sought. Here the authors prepare a stable, structurally flexible MOF that maintains high proton conductivity under a wide range of humidity.

    Sodium-ion batteries are a cost-effective alternative to lithium-ion for large-scale energy storage. Here Bao et al. develop a cathode based on biomass-derived ionic crystals that enables a four-sodium ion storage mechanism leading to exceptionally high specific capacity and energy density.

    Hydrogenation of CO2 over heterogeneous catalysts can produce useful energy vectors such as methanol and formic acid. Here the authors show that the activity of unsupported cobalt catalysts can be markedly enhanced through incorporation of nitrogen atoms into the structure.

    Understanding land-use requirements for the life cycle of electricity generation allows for consistent comparisons of different technologies. Jordaan et al. present a method that leverages highly resolved, empirical data sets to give robust estimates of land use for natural-gas-fired electricity.
