Joan Casey lived through frequent wildfire-season power outages when she lived in northern California.

The green hydrogen economy is a sustainable alternative to fossil fuels. However, one of the challenges of constructing a global hydrogen economy is hydrogen transportation by sea. A new paper proposes solid air as a medium for recycling cold energy across the hydrogen liquefaction supply chain.

Flying is the most damaging mode of transportation for our climate. At least, up until now.

Scientists are striving to develop ever-smaller internet-of-things devices, like sensors tinier than a fingertip that could make nearly any object trackable.

In the arid regions of the American Southwest, an unseen world lies beneath our feet. 

Tandem solar cells are made of stacked materials — such as silicon paired with perovskites — that together absorb more of the solar spectrum than single materials, resulting in a dramatic increase in efficiency.

Researchers at the University of California, Davis College of Engineering are using machine learning to identify new materials for high-efficiency solar cells. Using high-throughput experiments and machine learning-based algorithms, they have found it is possible to forecast the materials’ dynamic behavior with very high accuracy, without the need to perform as many experiments.

h-PdMo, a recently discovered catalyst, can convert carbon dioxide (CO2) into useful methanol at room temperature and low-pressure conditions, as demonstrated by researchers at Tokyo Tech. 

Scientists at four leading Illinois research institutions, three in the Chicago region, are forming a new collaboration to study the effects of drought on urban trees and develop more effective drought response strategies nationwide through a grant from the National Oceanic and Atmospheric Administration (NOAA).

Algae grown in transparent tanks or tubes supplied with carbon dioxide can convert the greenhouse gas into other compounds, such as food supplements or fuels. But the process leads to a buildup of algae on the surfaces that clouds them and reduces efficiency, requiring laborious cleanout procedures every couple of weeks.
