Cheaper, more effective cleanup of abandoned oil and gas wells

Abandoned oil and gas wells are a significant source of greenhouse gases but there are so many scattered across the United States that stopping the leaks presents a huge cost for states. Now, a research team including scientists ...

Biofilters reduce carbon footprint of old landfill sites

Researchers in the US are testing biofilter systems as a viable alternative to releasing methane from passive landfill vents into the atmosphere. The technology could reduce the overall impact of old landfills on global warming. ...

Startup creates underwater robotics with a human touch

It should be just as easy to use a robotic arm as it is to use your own hand. That's the thinking behind University of Washington startup BluHaptics, which is taking telerobotics—controlling robots from a distance—to ...

'Soil photosynthesis' helps to mitigate environmental pollution

NOx gases is the generic term used to refer to the group of gases made up of nitric oxide and nitrogen dioxide, gases that result from burning fossil fuel, and also from forest fires, volcanic eruptions and natural processes ...

Optimizing shale gas production from well to wire

"Hydraulic fracturing" (or fracking) and "environmentally friendly" often do not appear in the same sentence together. But as the United States teeters on the precipice of a shale gas boom, Northwestern University professor ...

Catalyst can control methane emissions in natural gas engines

A catalyst using a single or just a few palladium atoms removed 90% of unburned methane from natural gas engine exhaust at low temperatures in a recent study. While more research needs to be done, the advance in single atom ...

A step closer to decarbonising long-haul road transportation

Thanks to the urgent need to reduce greenhouse gas emissions, efforts to promote the deployment of low-carbon alternative fuels (AFs) in transport have intensified in recent years. However, these technologies haven't yet ...
