Notre Dame researchers create new tool to analyze embodied carbon in more than 1 million buildings in Chicago

University of Notre Dame — Wed, 04 Sep 2024 14:05:42 EST

The impact of embodied carbon in the built environment has been difficult to assess, due to a lack of data. To address that knowledge gap, Ming Hu, the associate dean for research, scholarship and creative work in Notre Dame's School of Architecture, and Siavash Ghorbany, a Notre Dame graduate student in civil and environmental engineering, have created a new tool to analyze the embodied carbon in more than 1 million buildings in Chicago. Their recently published research identifies 157 different architectural housing types in the city and provides the first ever visual analysis tool to evaluate embodied carbon at a granular level and to help inform policymakers seeking to strategically plan for urban carbon mitigation.

Defect engineering leads to designer catalyst for production of green hydrogen

University Of Illinois Grainger College Of Engineering — Wed, 07 Aug 2024 13:05:43 EST

Efficient technology for splitting the hydrogen-oxygen bond in water could be the key to producing low-cost, green hydrogen for energy storage at an industrial scale. Green hydrogen is expected to play a significant role in achieving the target of net zero carbon dioxide emissions. In a new study, an interdisciplinary group of researchers have identified a way to use "defect engineering" to significantly boost catalytic efficiency, taking science one step closer to sustainable, green hydrogen production.
