    Using photosynthetic microorganisms may be a route to sustainable hydrogen production from solar energy, but hydrogen generation is typically short lived. Here the authors address this challenge by engineering cyanobacteria to construct photosystem I–hydrogenase fusions that produce hydrogen in vivo.

    Rigidity, as seen in crosslinked polymers, and plastic processability are mutually exclusive properties. Here, the authors prepare a solution-processable conjugated microporous thermoset with permanent pores and demonstrate its application as a two-dimensional molecular sieving membrane for hydrogen separation.

    Understanding what underpins the activity and stability of oxygen evolution catalysts is an ongoing issue in the field of water splitting. Now, researchers show that balancing the rate of Fe dissolution and deposition over a metal hydr(oxy)oxide host yields dynamically stable Fe active sites, with the Fe–host interaction key to the performance.

    Anion exchange membrane water electrolysers have potential cost advantages over proton exchange membrane electrolysers, but their performance has lagged behind. Here the authors investigate the cause of the poor performance of anion exchange membrane electrolysers and design ionomers that can overcome some of the challenges.

    Light-driven production of hydrogen by coupling natural photosystems or photosensitizers with hydrogen-producing catalysts has been achieved in numerous in vitro systems. Now, a recombinant in vivo system is described that generates hydrogen using a hydrogenase enzyme directly coupled to a cyanobacterial photosystem.

    Understanding the activity and stability of oxygen-evolving anodes is crucial for developing better water splitting electrolysers. Researchers now show the importance of interactions between iron and hydr(oxy)oxide hosts in dynamically-stable electrocatalysts that balance dissolution and deposition of iron present in the electrolyte.

    Large-scale electrolytic production of hydrogen from water using renewable energy will require solutions to issues that arise when using intermittent power, such as gas mixing and low efficiency. To this end, an electrolysis system is now described that decouples the gas generation reactions and uses thermal energy to drive oxygen evolution.

    Catalysis is essential in the automotive and transportation sectors to target the United Nations sustainable development goals for climate change and the environment. To comply with both the ambitious United Nations goals and step-by-step stringent emission regulations, innovative and economically viable catalytic systems will be a key element in meeting these challenges.
