Machine learning (ML), a form of artificial intelligence that recognizes faces, understands language and navigates self-driving cars, can help bring to Earth the clean fusion energy that lights the sun and stars. Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) are using ML to create a model for rapid control of plasma — the state of matter composed of free electrons and atomic nuclei, or ions — that fuels fusion reactions.

Scientists have created a novel method for measuring the stability of a soup of ultra-hot and electrically charged atomic particles, or plasma, in fusion facilities called “tokamaks.” Involving an innovative use of a mathematical tool, the method might lead to a technique for stabilizing plasma and making fusion reactions more efficient.

Artificial intelligence (AI), a branch of computer science that is transforming scientific inquiry and industry, could now speed the development of safe, clean and virtually limitless fusion energy for generating electricity. A major step in this direction is under way at the U.S.

Engineering professor Lynn Loo, director of the Andlinger Center for Energy and the Environment, says the dangers of climate change are so pressing that it’s time for all hands on deck to decarbonize the U.S. and global economies. She praises the issue awareness behind legislation introduced in Congress to implement a “Green New Deal,” but stresses that solar and wind technologies, by themselves, are not yet sufficient to fuel the nation. “We’re always racing against time,” explains Loo.

Widespread use of autonomous vehicles (AVs) could either massively increase or drastically cut greenhouse gas emissions depending, in large part, on public policy, according to new research from Princeton University.

Carbon dioxide emissions rose in the U.S. by 3.4 percent in 2018, according to preliminary estimates released this week. Increased electricity demand and economic growth are among the contributing factors the report cites. Interestingly, electricity production from coal actually dropped last year.
Experts Judi Greenwald, Eric Larson and Michael Oppenheimer from Princeton University’s Andlinger Center for Energy and the Environment comment on the news.

With the right public infrastructure investment, the United States could as much as double the amount of carbon dioxide emissions currently captured and stored worldwide within the next six years, according to an analysis by Princeton University researchers.

Abhi Raj, a Ph.D. candidate in electrical engineering, has been selected by the U.S. Department of Energy (DOE) as one of 47 recipients of a fellowship from the Office of Science Graduate Student Research Program. The awards support doctoral-thesis research and allow students to work for up to 12 months in one of 17 DOE laboratories.

Europe’s decision to promote the use of wood as a “renewable fuel” will likely greatly increase Europe’s greenhouse gas emissions and cause severe harm to the world’s forests, according to a new comment paper published in Nature Communications.

Hydraulic fracturing, or fracking, provides critical energy for society, but also uses large amounts of fresh water while producing corresponding amounts of wastewater. Water-based foams, which use about 90 percent less water than fracking fluids, provide an alternative, but the mechanism for foam-driven fracture in such drilling is not well understood.
