Updated facility‐level inventory and LCIA of the public electricity grid in Ontario, Canada

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract As the composition of Ontario's electricity grid will change over time, it is important to have a comprehensive understanding of the environmental impacts of Ontario's electricity grid as it stands today. However, publicly available information on impacts of Ontario's electricity grid is available only in aggregate from government sources.

Rock mechanical properties under reconstructed deep in situ thermo–hydro–mechanical conditions: Implications for CO₂‐related injection scenarios

Deep Underground Science and Engineering, EarlyView.
The graphical abstract illustrates a reconstructed in situ thermo‐hydro‐mechanical (THM) framework in which porosity serves as the central variable linking stress, pore pressure, and temperature to evolving mechanical properties of rocks. Under burial conditions, in situ stress, pore pressure, and temperature jointly govern volumetric strain and ...
