Extreme Heat, Hurricanes, Wildfires: How Summer’s Extremes Disrupt the Power Grid
Every second of every day, utilities monitor the flow of power through the nation’s electric grid, monitoring whether power generated matches power demanded by homes, businesses, vehicles and more. For every disruption, grid operators must work quickly to ensure that power goes where it’s needed.

Uncovering the Spatial Gene Expression of Major Cell Types from the Stems of Sorghum
Sorghum
is a sustainable resource for
biofuels
and
bioproducts.
Its stem, rich in sucrose, has great potential for bioethanol and biopolymer production. However, more research is needed on gene expression and regulation in stem cells.

Gases from Burning Biomass React within Clouds, Forming Secondary Organic Aerosols
Thousands of tiny, invisible atmospheric particles scatter and absorb solar radiation, contributing to cloud formation. Many of these particles form through reactions between gases and oxidants in various atmospheric phases, including gas and liquid in clouds and other particles.

Unraveling How Potassium Bound to Soil Minerals is Made Bioavailable for Uptake by Plants
A combination of X-ray
absorption
spectroscopy and computational methods revealed the unique bonding environment of potassium associated with organic acids. Potassium is an essential element for plant growth. However, soils generally have low amounts of potassium readily available to plants.

Probing carbon capture, atom-by-atom
Scientists at Lawrence Livermore National Laboratory (LLNL) have developed a machine-learning model to understand
Carbon Dioxide (CO2)
capture in amine-based sorbents at the atomic level. This innovation aims to improve the efficiency of direct air capture technologies, essential for reducing atmospheric CO2.

Flipping the Script on Traditional Wind Turbine Technologies
Most wind turbines face the wind—and there is a good reason for that. Since the 1980s, wind turbine developers have been using what is called the “Danish concept” for their designs—three blades, positioned upwind (i.e., facing the wind), that are engineered to keep facing the wind to maximize energy production.

The Grid Can Handle More Renewable Energy, But It Needs Some Help
The grid needs to change. To electrify everything from vehicles to heating systems to stovetops, the U.S. grid must expand by about 57% and get more flexible, too. Solar and wind energy are the
renewables
most likely to dominate a future clean energy grid. But they are found primarily in remote areas, far from the hubs that need their power.

It’s all in the accounting
Natural
ecosystems
can offset manmade Carbon Dioxide (CO2) and greenhouse gas emissions, but accurate accounting is essential for effective carbon offset policies. Researchers from Europe and the United States, including Lawrence Livermore National Laboratory (LLNL), are conducting experiments to determine if forests are annual CO2 sinks or sources.

Enormous Diversity and Biogeochemical Potential Is Contained within the Soil Virosphere
Soils are among the largest viral
reservoirs
on Earth. Yet historically, soil viruses have been ignored. Recent work indicates the soil virosphere as a critical factor in human and environmental health. Nonetheless, our understanding of global soil viral distributions, activities, and interactions with the soil microbiome remains limited.

A FORCEE for good: Growing Sandia’s climate and earth sciences internship
The FORCEE institute provides undergraduate and graduate students with real-world experience in conducting research on topics in
earth sciences,
climate change,
decarbonization and infrastructure modernization. The students receive mentorship, attend facility tours and seminars, and can take part in an end-of-summer symposium to present their findings.

Machine learning advances the clean-energy economy
Los Alamos National Laboratory (LANL) scientists are developing powerful
machine learning
models — an application of
artificial intelligence
— to simulate underground hydrogen storage operations under various cushion gas scenarios. This will play a vital role in the low-carbon economy of the future.
