Great winds of China

China has the world’s largest installed wind capacity, yet its electricity generation from wind is not on par with that of the US. Lu et al. quantify the relative contributions of wind power curtailment, lower turbine quality and delayed grid connection to the sub-optimal electricity generation in China.

See Lu et al. 1, 16061 (2016) and News & Views by Joanna Lewis, article 16076.

    Redox mediators facilitate the oxidation of the highly insulating discharge product in metal–oxygen batteries during recharge and offer opportunities to achieve high reversible capacities. Now a design principle for selecting redox mediators that can recharge the batteries more efficiently is suggested.

    Combatting climate change is often considered to bring about security of energy supply by reducing reliance on imports. By modelling the impact of pursuing energy security policies, a study now finds that the inverse situation is less advantageous for the global climate.

    Coupling high ionic and low electronic conductivity in the electrolyte of low-temperature solid-oxide fuel cells remains a challenge. Now, the electronic conductivity of a perovskite electrolyte, which has high proton conductivity, is shown to be heavily suppressed when exposed to hydrogen, leading to high fuel cell performance.

  • Analysis |

    Several factors, such as wind power curtailment and quality of turbines, cause a reduced capacity of wind energy production in China compared with the US. The authors quantify the relative weight that these factors have in limiting the wind power output in China, and provide policy recommendations.

    The ability of photovoltaic devices to harvest solar energy can be enhanced by tailoring the spectrum of incident light with thermophotovoltaic devices. Bierman et al. now show that one such device achieves a solar-to-electrical efficiency of 6.8%, exceeding that of the solar cell alone.
