Analysis of hydrogen production costs in Steam-Methane Reforming considering integration with electrolysis and CO<sub>2</sub> capture
منشور في 2022"…Integration with electrolysis is shown to be less attractive compared to the proposed heat and power integration schemes for the SMR process with CO<sub>2</sub> capture and compression for subsequent sequestration or utilization, which can reduce emissions by 90% with hydrogen production costs increasing only moderately by 13%. This blue hydrogen production is compared in terms of costs and emissions against the emerging alternative production by electrolysis in the context of renewable and fossil electricity generation and electricity mixes while considering life-cycle emissions.…"

Reduced fertigation input sustains yield and physiological performance for improved economic returns and cleaner production of greenhouse eggplant
منشور في 2024"…We found that morphological traits such as plant height and leaf number were consistent across EC levels, while fruit weight, length, and width are significantly higher at the lowest EC (1.8). Photosynthetic rates increased significantly with rising EC levels, while other gas exchange parameters such as stomatal conductance, intrinsic water use efficiency, and vapour pressure deficit were similar for all EC levels tested. …"
