Assessing connectivity between an overlying aquifer and a coal seam gas resource using methane isotopes, dissolved organic carbon and tritium [PDF]

, 2015
Coal seam gas (CSG) production can have an impact on groundwater quality and quantity in adjacent or overlying aquifers. To assess this impact we need to determine the background groundwater chemistry and to map geological pathways of hydraulic ...

Modulating Surface‐Active Hydrogen for Facilitating Nitrate‐to‐Ammonia Electroreduction on Layered Double Hydroxides Nanosheets

Advanced Functional Materials, EarlyView.
The NiCuFe‐layered double hydroxides nanosheets are synthesized for facilitating nitrate‐to‐ammonia with a high ammonia yield of 1.64 mmol h−1 cm−2, Faradaic efficiency of 94.8% and stability for 15 cycles. The assembled Zn‐nitrate battery delivers a remarkable power density of 12.4 mW cm−2.

A Coupled Hydro‐Mechanical Modeling Framework to Concurrently Simulate Coal Seam Gas Induced Subsidence and Groundwater Impacts

Water Resources Research
Land subsidence has been extensively studied and modeled in the context of conventional petroleum or water extraction. New challenges arise to model subsidence caused by coal seam gas (CSG) depressurization. CSG‐induced subsidence is a result of multiple

Global Groundwater Sustainability

Groundwater, 2020
No abstract but introduction: Groundwater resources are the most reliable source of freshwater on the planet, so long as they are sustainably managed. While serious groundwater depletion and contamination are well documented in several regions around the world, other regions have the potential to leverage under-developed groundwater resources to fuel ...
