    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.
