The integrated solar flow battery device contains both a solar cell to convert sunlight into electricity and chemicals that can store the electricity for later use. Credit: Wenjie Li Chemists at the University of Wisconsin-Madison and their collaborators have created a highly efficient and long-lasting solar flow battery, a way […]

A black hole as a source of energy? We know black holes as powerful singularities, regions in space time where gravity is so overwhelming that nothing—not even light itself—can escape. About 50 years ago, British physicist Roger Penroseproposed that black holes could be a source of energy. Now, researchers at the […]

Animation After his PhD thesis invalidates an old assumption, Norman Cao wonders what’s next. “What are some challenges in controlling plasma and what are your solutions? What is the most effective type of fusion device? What are some difficulties in sustaining fusion conditions? What are some obstacles to receiving fusion funding?” For […]

New roll-to-roll production method could enable lightweight, flexible solar devices and a new generation of display screens. A new way of making large sheets of high-quality, atomically thin graphenecould lead to ultra-lightweight, flexible solar cells, and to new classes of light-emitting devices and other thin-film electronics. The new manufacturing process, which […]

At the Department of Energy Manufacturing Demonstration Facility at ORNL, this part for a scaled-down prototype of a reactor was produced for industry partner Kairos Power.

Researchers developed a technique that uses a scanning tunneling microscope integrated with lasers and other optical components to trap appropriate molecules and measure the energy distribution of hot electrons in a thin gold film. Credit: Illustration by Enrique Sahagún Highly energetic, “hot” electrons have the potential to help solar panels […]

This graphical abstract summarizes how this work performs a comprehensive techno-economic analysis worldwide for photovoltaic systems using a combination of bifacial modules and single- and dual-axis trackers. The researchers found that single-axis trackers with bifacial modules achieve the lowest LCOE in the majority of locations (16% reduction on average). Yield […]

The 1250 ton cyrostat base is positioned over the ITER tokamak pit for installation. This base is the heaviest lift of tokamak assembly. Credit: ITER Organization ITER, the world’s largest international scientific collaboration, is beginning assembly of the fusion reactor tokamak that will include 12 different essential hardware systems provided […]
