Dry casks take the heat

Sandia National Laboratories has built a scaled test assembly to mimic a dry cask storage container for spent nuclear fuel. The team is providing new data on how fuel temperatures change during storage and affect the integrity of the metal cladding surrounding the spent fuel.

New research seeks to optimize space travel efficiency

A team of researchers has developed a framework to optimize fuel and resource usage in space travel. By considering multiple missions together, or campaigns, they can minimize launch mass and cost. The study also explores the use of propellant depots in space, which could significantly reduce fuel needs for future missions.

Bionic leaf

Scientists from Harvard University have developed a system that harnesses solar energy and converts it into a liquid fuel using bacteria. The 'bionic leaf' uses an artificial catalyst to split water into hydrogen and oxygen, which is then converted by a bacterium into the liquid fuel isopropanol.

National Renewable Energy Laboratory updates cetane data used for development of energy efficient fuels and engines

The National Renewable Energy Laboratory has released an updated compendium of experimental cetane numbers, which provides vital information for the development of new, low-carbon fuels and compatible engines. The update includes additional measurements on a larger number of compounds, along with data quality assessments.

Inter-dependent networks stress test

Interdependent networks, such as energy production systems, are more vulnerable to cascading failures due to one-directional connections. The study found that redundancy in connections can impact robustness, with less reliable systems operating near critical thresholds.

Solar panels light the way from carbon dioxide to fuel

Researchers at Princeton University have developed an efficient method for harnessing sunlight to convert carbon dioxide into formic acid, a potential alternative fuel. The process achieves nearly 2% energy efficiency, twice that of natural photosynthesis, and has the potential to store solar energy in fuel cells.
