What’s the best way to expand the US electricity grid?

Growing energy demand means the U.S. will almost certainly have to expand its electricity grid in coming years. What’s the best way to do this? A new study by MIT researchers examines legislation introduced in Congress and identifies relative tradeoffs involving reliability, cost, and emissions, depending on the proposed approach. The researchers evaluated two policy approaches to expanding the U.S. electricity grid: One would concentrate on regions with more renewable energy sources, and the other would create more interconnections across the country. For instance, some of the best untapped wind-power resources in the U.S. lie ...

Developing a new electric vehicle sound

HONOLULU, Dec. 1, 2025 — One of the many benefits of electric vehicles is that they are much quieter than traditional gasoline-powered vehicles. In some cases, though, they are too quiet. Automakers are required to design their vehicles so they emit sounds at low speeds to alert pedestrians to their presence. However, aside from some basic regulations regarding volume, automakers are free to choose whatever noise they wish their vehicles to emit. This freedom gives researchers a unique opportunity to design custom sounds to maximize their effectiveness. Graduate ...

Cobalt-induced asymmetric electron distribution boosts photocatalytic hydrogen production efficiency

Hydrogen production from solar-driven water splitting serves as a crucial technology to sustainably access zero-carbon H2 energy. Toward large-scale application, cost-effective cocatalysts—such as transition metal sulfides—with high H2 evolution activity and excellent stability are desperately needed to greatly boost the solar-to-hydrogen conversion efficiency. Unfortunately, the intrinsic symmetrical electron distribution in crystalline metal sulfides usually causes an improper electronic configuration between catalytic S atoms and H intermediates (Had) to form strong S-Had bonds, ...

SwRI tackles pre-ignition challenges in hydrogen-fueled engines

SAN ANTONIO — November 26, 2025 — Engineers at Southwest Research Institute (SwRI) have developed a reliable testing methodology to study stochastic pre-ignition (SPI) in hydrogen-fueled internal combustion engines (H2-ICEs), offering the automotive industry tools to address challenges associated with hydrogen fuel and advance cleaner engine technologies. Pre-ignition, where unintentional combustion occurs before spark timing, is disruptive and sometimes detrimental to engine performance and durability. While hydrogen's low ignition threshold is a suspected SPI factor, SwRI explored whether lubricant autoignition contributes to SPI in H2-ICEs. “H2-ICEs ...

New membrane sets record for separating hydrogen from CO2

BUFFALO, N.Y. – When designing membranes that separate industrial gases, scientists often incorporate structures that attract the gas they want to obtain. This attraction can enhances the membrane’s permeability, and help isolate the desired gas more efficiently. A study today in Science Advances shows sometimes the opposite can occur – the chemically enhanced membrane can bind too strongly to the intended gas, thus slowing the membrane’s permeability and reducing the separation efficiency. “It’s very counterintuitive, and it challenges traditional thinking in gas separation science,” says the study’s corresponding author Haiqing Lin, ...
