A space-time simulator for hourly wind and solar energy fields

Yash Vijay Amonkar, David J Farnham, Upmanu Lall

Published: 2024-06-26
Subjects: Engineering

Spatially distributed renewable energy generation poses unique risks to power systems since the aggregate amount of energy produced in any hour depends on the spatial correlation structure of the sources. Moreover, the spatial correlation structure can vary with the time of day and season and depend on the state of the large-scale climate. These features pose a challenge for resource adequacy [...]

Can Surface Water Color Accurately Determine Sediment Concentration and Grain Size? A Hyperspectral Imaging Study

Ruo-Qian Wang, David Bazzett

Published: 2024-06-14
Subjects: Education, Engineering

Water color changes are closely linked to variations in suspended sediment characteristics, motivating efforts to reliably determine sediment concentration and size through remote sensing. However, current turbidity measurement practices that rely on empirical correlations have not been rigorously tested in the lab and the past testing was limited to limited particle conditions, leading to a wide [...]

The migration of hydrogen in sedimentary basins

Published: 2024-06-13
Subjects: Engineering, Physical Sciences and Mathematics

Understanding the mechanisms of large-scale, subsurface hydrogen migration is essential for natural hydrogen exploration and for hydrogen storage assessment. The unique properties of hydrogen make that the timescales of hydrogen migration within geological basins vary from thousands of years to days. Within the shallow Earth, diffusive and advective transport mechanisms are dependent on a wide [...]

Experimental evaluation of two-layer air bubble curtains to prevent seawater intrusion into rivers

Ehsan Kahrizi, Seyed Ali Akbar Salehi Neyshabouri, Amin Zeynolabedin, et al.

Published: 2024-05-21
Subjects: Engineering

The seawater intrusion (SWI) into rivers can lead to many negative consequences, especially on agricultural activities and live ecosystems in upstream areas of rivers. One solution to prevent SWI is using air bubble curtains (ABCs). The objective of this study is to investigate the optimal location of ABCs and airflows. To this end, several tests with different flow and salinity rates were [...]

Subjects: Engineering, Physical Sciences and Mathematics

The EU considers climate change as an existential threat and wants to reduce net greenhouse gas emissions by at least 55% by 2030 and down to 0% by 2050 within the "EU Green Deal" and economic growth should be decoupled from the use of energy resources. It therefore sees fighting climate change as one of the most important targets1. There is considerable dis-consensus about growing CO2 levels in [...]
