    The growing deployment of solar panels in urban areas requires tools to determine their optimal placement and electricity yield. Towards this end, this study presents a simplified model based on the sky view and sun coverage factors and validates it using real-world data from different systems in different climates.

    This Article presents a battery with protons as the charge carrier, as opposed to Li-ion batteries, which rely on the transport of Li-ions. Protons are conducted by means of the Grotthuss mechanism in a hydrated Prussian blue analogue electrode, offering potential for ultrafast rate and long-life batteries.

    Blockchain-based distributed management of electricity systems is an important step towards making these systems more resilient. Although there are many implementations, here the researchers formalize a basic template for smart contracts that can be built upon for distributed electricity systems management.

    Luminescent solar concentrators are promising for semi-transparent, building-integrated photovoltaic systems. Here the authors minimize the absorption losses by relying on fast energy transfer in multiphase perovskite nanoplatelets to achieve optical quantum efficiency of 26% on 100 cm2 devices.

    The answer to seasonal energy storage and security to support highly renewable power systems could lie deep under the seabed, where compressed air energy storage offers a route to long-term storage at large scales. Now, research models the potential for this in porous rock and finds a large capacity in saline aquifers offshore in the UK.
