NET result

Direct air capture (DAC) of CO2 is a promising negative emissions technology (NET) that could help to achieve climate targets. However, the energy and materials demands of DAC need to be better understood. Based on industrial data, Deutz and Bardow evaluate the environmental impacts of two DAC plants operated by Climeworks using life-cycle assessment.

Editorial

  • The milestones in rechargeable lithium-ion battery development have been widely reported but the first-hand accounts from inventors have often not been. We aim to bring their personal stories to wider attention with a new article series.

Comment & Opinion

  • Energy research works with units and concepts forged in an age of fossil fuel, leading to problem formulations that reinforce current societal practices and patterns of consumption. Achieving low-carbon energy goals depends on shifting demand to match supply and reconceptualizing interactions between time and energy.

  • Energy scenarios project future possibilities based on a variety of assumptions, yet do not fully account for inherent friction in the energy transition, particularly over the near term. A new study shows how machine learning can complement existing scenario tools by incorporating lessons from the past into projections for the future.

Tales of Invention

  • It is now almost 50 years since the first rechargeable lithium batteries, based on the reversible intercalation of lithium into layered structured titanium disulfide, were conceived. They were the precursor to the structurally related layered oxides that now dominate energy storage for electronics, the grid and vehicles.
