Buildings — Cooking with hydrogen

A prototype cooking appliance developed by Oak Ridge National Laboratory uses a 50% blend of hydrogen and natural gas, offering an alternative to safely reduce emissions that contribute to the nation’s carbon footprint.

Environment — Clean water bots

Measuring water quality throughout river networks with precision, speed and at lower cost than traditional methods is now possible with AquaBOT, an aquatic drone developed by Oak Ridge National Laboratory. 

The maneuverable AquaBOT measures water quality indicators such as nitrate, temperature and dissolved oxygen along the entire length of mid-sized streams where water quality can be variable.

New perspective highlights promise of hybrid approach for cellulosic biofuel production

The rapid pace of global climate change has added urgency to developing technologies that reduce the carbon footprint of transportation technologies, especially in sectors that are difficult to electrify. In response, researchers collaborating through the Center for Bioenergy Innovation make the case that scientific advances support a hybrid approach using biological and catalytic methods for producing cellulosic biofuel for use in airplanes, ships and long-haul trucks.

Dongarra named Turing Award recipient for advances in high-performance computing, AI

Jack Dongarra, an innovator in computational software development who holds joint appointments at the University of Tennessee and Oak Ridge National Laboratory, will receive the 2021 A.M. Turing Award from the Association for Computing Machinery. The award recognizes his pioneering contributions to numerical algorithms and libraries that enabled high-performance computational software to keep pace with exponential hardware improvements for over four decades.

ORNL scientists dig into role of manganese in soil carbon and climate change

While most people think first of atmospheric carbon emissions from fossil fuels when considering climate change, the planet’s soil actually stores more carbon and could become a major source of carbon release or a mitigation tactic in the years ahead. Just how soils store carbon, when and how much they release to the atmosphere, and how to get them to absorb more is the subject of intense research as scientists race to understand the processes at play, predict environmental change and use that knowledge to help heal the planet.
