Researchers at MIT have identified , quantified, and modeled a major reason for the poor performance of electroreduction processes to convert CO 2 to fuel or other useful chemicals. The findings could spur progress on developing a variety of materials and designs for electrochemical carbon dioxide conversion systems. —Soto et al.

Realizing that less attention has been paid to the potential footprint of autonomous vehicles, the MIT researchers built a statistical model to study the problem. kW yields emissions equal to emissions of all data centers. The research appears in the January-February issue of IEEE Micro. computer power of 0.84 Sudhakar et al.

To date, however, only small all-electric planes have gotten off the ground. Their electric motors generate hundreds of kilowatts of power. These would be propelled by hybrid or turbo-electric propulsion systems where an […] Aviation’s huge carbon footprint could shrink significantly with electrification.

Researchers at MIT and their colleagues are proposing a new design for electrodes that, based on the long-sought goal of using pure lithium metal as the anode, could lead to longer-lived batteries with higher energy densities. We designed this structure that gives us three-dimensional electrodes, like a honeycomb. —Ju Li.

Scientists have made a major advance in harnessing machine learning to accelerate the design for better batteries. The goal is to bring together foundational research and industry know-how to develop a long-lived electric vehicle battery that can be charged in 10 minutes. Hongbo Zhao/MIT). —Will Chueh.
