ORNL researchers demonstrated that an additive made from polymers and electrolytes improves the thermal performance and stability of salt hydrate phase change materials, or PCMs, a finding that could advance their integration into carbon-reducing heat pumps.

Griffiths and her colleagues are examining how much methane and carbon dioxide is released from the reservoir. Their aim is to better understand and predict how much of these climate-warming gases are coming from reservoirs across the nation.

Making room for the world’s first exascale supercomputer took some supersized renovations.

Researchers used the world’s first exascale supercomputer to run one of the largest simulations of an alloy ever and achieve near-quantum accuracy.

The world’s first exascale supercomputer will help scientists peer into the future of global climate change and open a window into weather patterns that could affect the world a generation from now.
