The efficiency and durability of solar-powered devices for hydrogen production continue to improve, but more large-scale, real-world demonstrations are needed to progress the technology.
Despite increased attention, residential energy insecurity is a widespread and persistent problem in the USA. We commend ongoing investigations, urge scholars to continue to examine why some households disproportionately experience energy insecurity, and offer several lines of inquiry that may help reduce energy insecurity’s incidence and impact.
Today’s sodium-ion batteries can not only be used in stationary energy storage applications, but also in 160–280 mile driving-range five-passenger electric vehicles. This technology will alleviate some of the supply-chain issues arising from limited resources of materials used in the ubiquitous lithium-ion batteries.
Differences in the approach to community acceptance of energy technologies can muddy visions of energy futures. Acknowledgement of the tensions around justice perspectives and the degree of desired change can improve scholarship and policy dialogue.
José Miguel Bermúdez Menéndez, energy technology analyst on hydrogen and alternative fuels at the International Energy Agency (IEA), talks to Nature Energy about the IEA’s Hydrogen Projects Database, which was last updated in October 2022.
