    Planning of distributed energy resources requires careful consideration of many socio-technical factors to ensure that it is optimally built. Jain et al. present a model that incorporates numerous such factors and use it to find cost-effective resources for a sample of 10,000 consumers in California.

    Concentrator photovoltaics achieve high efficiency but have so far been impractical for use on rooftops. Here, Price et al. develop a flat-panel concentrating photovoltaic system based on a triple-junction solar cell that operates at fixed tilt over a full day with >30% peak efficiency.

    Pseudocapacitors based on redox-active materials have relatively high energy density but suffer from low power capability. Here the authors report that two-dimensional transition metal carbides exhibit high gravimetric, volumetric and areal capacitance values at high charge/discharge rates.

    Electrical energy storage is expected to be important for decarbonizing personal transport and enabling highly renewable electricity systems. This study analyses data on 11 storage technologies, constructing experience curves to project future prices, and explores feasible timelines for their economic competitiveness.

    Metal alloys possessing core–shell structures have potential as low-Pt catalysts for the oxygen reduction reaction in fuel cells, but can suffer from poor stability. Using high-resolution microscopy, Li et al. find that a Pt–Pd–Au catalyst undergoes surface atomic rearrangement and becomes more active on electrochemical cycling.

    Climate change will affect future water availability and temperature and hence thermoelectric power generation, which uses water for cooling. This study explores future usable capacity for existing thermoelectric power under different scenarios, including US state-level environmental regulations.

    Wind turbines have been a go-to technology for addressing climate change, but they are increasingly a source of frustration for all stakeholders. While community ownership is often lauded as a panacea for maximizing turbine acceptance, a new study suggests that decision-making involvement — procedural fairness — matters most.

    The UN Sustainable Development Goal 7 aims to deliver affordable, reliable, sustainable and modern energy for all. Tracking progress towards the targets under this goal can spur better energy statistics and data gathering capacity, and will require new indicators that also consider the interplay with other goals.

Burning to compress

High loading of active materials at the cathode is essential to realise the high energy density potential of Li-S batteries, but conventional cathodes have a non-compact structure that severely limits the active material loading. Tan et al. report that by burning Li foils in a CS2 vapour, highly compact Li2S–graphene nanocapsules are obtained (represented here) that can be used in high-performing Li-S batteries.
