    Dedicated energy crops are an important feedstock for bioenergy systems, but uncertainties remain over how best to integrate them into agricultural landscapes. Here, the authors use high-resolution ecosystem modelling to explore how selection of the soils cultivated and fertilizer application rates affects feedstock costs and emissions footprints.

    Protonic ceramic fuel cells use oxide electrolytes with high protonic conductivity but suffer from low power densities due to sluggish oxygen reduction kinetics and high contact resistances. Here the authors integrate a PrBa0.5Sr0.5Co1.5Fe0.5O5+δ cathode and a BaZr0.4Ce0.4Y0.1Yb0.1O3 electrolyte, achieving exceptional power density and stability.

    Electrocatalysts with improved activity and stability for the conversion of CO2 to CO are being sought. Using operando spectroscopies, the authors identify atomically dispersed Ni(i) as the active site in a nitrogenated-graphene-supported catalyst with high intrinsic activity and stability over 100 hours.

    The Carnot efficiency and the power output of thermoelectric power generation increase with temperature but current thermoelectrics are characterized up to 1,500 K. Here, Li et al. develop reduced graphene oxide films that can convert heat up to 3,000 K with high power factors, opening the door for novel applications.

    The sustainability of biomass production for energy depends on site-specific biophysical and socio-economic conditions. New research using high-resolution ecosystem process modelling shows the trade-offs between economic and environmental performance of biomass production for an ethanol biorefinery.

    Smart integrated transport and energy systems need to interact with end users to enable the exploitation of demand flexibility. New research shows that relying on assumptions about user behaviour, rather than on data-based empirical models, inflates the benefits of smart-charging programmes.

    US Secretary of Energy Rick Perry may have lost his bid to prop up coal and nuclear power, but he has started a valuable conversation about the grid and its resilience.

    Electrochemical conversion of CO2 to fuels is an attractive pathway to store electrical energy in chemical form. Isolated, low-valent Ni species in nitrogen-doped graphene are now demonstrated to selectively convert CO2 to CO electrochemically with high intrinsic activity and stability.
