Hurricane damage leads to power outages and can trigger cascading failures in power grids as they respond to the initial impacts. Stürmer et al. present a dynamic approach to modelling these wind-induced power-line failures that allows them to test the potential effects of line hardening in providing a more resilient power grid.
One of the major challenges in realizing lithium (Li)-metal batteries is the instability of Li metal in the electrolyte. Now, a study unveils the significant role of lithium oxide in protecting Li metal, thereby contributing to stable battery operation.
The shift towards low-carbon heating technologies and associated infrastructure often disrupts citizens’ lives. Research now demonstrates how the socio-psychological context may influence the circumstances under which citizens are willing to accept heating transitions and related construction work, and those where reactance and rejection is to be expected.
The activation barriers of interfacial energy conversion reactions are key to controlling the efficiency of electrolysers. Work on the structural dynamics of water during charge transfer at electrified solid/liquid interfaces now brings greater understanding of the components of the activation barriers for water dissociation and hydrogen evolution.
During extreme storms, the failure of a small fraction of transmission lines can trigger a cascade of outages in a power grid. Going beyond static approaches, it is now demonstrated that resolving the spatio-temporal interactions between the storm and the power grid is key to identifying these critical lines.
Using a hybrid fixture, application of an appropriate external pressure on Li-metal pouch cells with a liquid electrolyte considerably reduces cell swelling. Mapping of the pressure distribution across the cell surface provides insight into the electroplating process that could inform strategies to overcome uneven Li plating on the Li-metal surface.
Pay-as-you-go energy systems are a promising market-based approach to paying for energy in small amounts in sub-Saharan Africa; however, implementation and the suitability of current business models show room for improvement. This Perspective outlines an agenda for more inclusive PAYG systems.
Understanding how power systems fail—and the nature of cascading failures—as a result of hurricanes is important to increase future resilience. Here the authors present a co-evolution approach to modelling wind-induced power line failures caused by hurricanes and assess the potential impact of line hardening on grids.
Manufacturing of perovskite solar cells under ambient conditions is desirable. Meng et al. show that dimethylammonium formate suppresses halide oxidation and deprotonation of organic cations, enabling air-processed inverted solar cells with 24.7% efficiency.
Ion solvation at solid–electrolyte interfaces is crucial in various components of energy conversion technologies, including water splitting electrocatalysts and bipolar membranes, but is poorly understood. Here the authors study ion solvation kinetics in these systems, highlighting the key role of interfacial capacitance in determining behaviour.
Cell swelling poses a considerable obstacle in the development of lithium-metal batteries. Here the authors report the use of a hybrid pressure-application fixture to substantially reduce swelling, analyse the pressure distribution across the cell surface and provide insights for further battery stabilization.
A new study considers how disruption to energy systems is experienced and takes on meaning. On the basis of workshop data, the study finds that public views of heat decarbonization in the United Kingdom are shaped by relationships to family, cultural expectations, housing and financial position.
Electrolyte design strategies for lithium batteries rely on tailoring the composition of lithium–electrolyte interphases. Here lithium oxide is shown to be a key component of these interphases, making oxygenation an effective approach to achieve high efficiency.
Wide-bandgap perovskite solar cells suffer from phase segregation. Zhang et al. show that thiocyanate ions overcome the issue by occupying iodide vacancies while regulating crystallization, enabling perovskite/organic tandem cells with 25.06% efficiency.
A new study finds that strategically integrating floating solar panels on reservoirs could substitute 20–100% of Africa’s planned hydropower by 2050. For the Zambezi watercourse, this approach generates a more stable electricity supply compared with hydro-dominated development.
Capacity is often used to evaluate and monitor battery state and health. Now, lithium inventory transactions can be accurately tracked at the electrode–electrolyte interface to improve battery performance and reliability.
