    For proton-conducting metal–organic frameworks (MOFs) to find application as the electrolyte in proton-exchange membrane fuel cells, materials with better stability and conductivity are required. Now, a structurally flexible MOF that is also highly stable is demonstrated to possess high proton conductivity over a range of humidities.

    Understanding how subsidies affect fossil-fuel investment returns and production is crucial to commencing new reforms. New analysis on the impact of subsidies on US crude-oil producers finds that, at recent oil prices of around US$50 per barrel, tax preferences and other subsidies push nearly half of new oil investments into profitability.

    Household income is a typical measure of inequality, but it is limited by under-reporting, especially for rural Chinese households. A new study shows that energy consumption measures service flows of household durable electronics, which can provide more precise measurement of rural wealth inequalities and distributions.

    Confining sulfur in high-surface-area carbon is a widely adapted approach in Li–S batteries, but it often results in low sulfur utilization and low energy density. Now, controlled nucleation of discrete Li2S particles on a network of low-surface-area carbon fibres provides a possible solution to the endemic problems of Li–S batteries.

    President Trump has proposed severe cuts to US government spending on energy research, development and demonstration, but Congress has the ‘power of the purse’ and can rescue US energy innovation. If serious cuts are enacted, the pace of innovation will slow, harming the economy, energy security and global environmental quality.
