  • Water storage requires evidence-based approach

    Coping with climate change requires a greater understanding of the options for water storage, writes hydrology expert Matthew McCartney. The lack of water is a major cause of food insecurity and poverty among the world's poorest people. But for many, the problem is not water scarcity per se, but the inability to manage rainfall variability. In Sub-Saharan Africa, for example, ...

  • Continuous Ground Gas Monitoring Technical Article

    It is almost inevitable in the initial phases of a construction sites development, that a Ground Gas risk assessment process is required by the local planning authority, and subsequently undertaken by a developer or their contractor. This normally encompasses spot monitoring visits that can last up to 12 months or more, if methane is found at over 5% by volume. However, it is important to realise ...

  • Written Ministerial Statement by Edward Davey: Exploration for shale gas

    Edward Davey, Secretary of State for energy and climate change Shale gas development has been of increasing importance in the US for some years, but exploration has only just begun in the UK. The potential of producing shale gas from a suitable formation can only be established by fracturing the rock, and it happens that the fracturing of the first shale gas well in the UK, at Preese Hall ...

  • DOE selects projects to monitor and evaluate geologic CO2 storage

    The U.S. Department of Energy (DOE) has announced the selection of 19 projects to enhance the capability to simulate, track, and evaluate the potential risks of carbon dioxide (CO2) storage in geologic formations. The projects' total value is approximately $35.8 million over four years, with $27.6 million of DOE funding and $8.2 million of non-Federal cost sharing. The work will be managed by ...
