GISERA's latest research is focussing on "naturally occurring emissions" of methane that has raised eyebrows, but Professor Barrett defends the focus. Questions raised over commitment to reduce greenhouse gases Its chairman, Professor Damian Barrett, denies that gas industry funding and involvement compromises the independence of CSIRO's research, arguing that there are robust governance controls in place. The gas industry is funding further research through a body known as GISERA, the Gas Industry Social and Environmental Research Alliance, which includes the CSIRO.Īlthough they have equal voting rights, gas industry executives and spin doctors outnumber scientists on GISERA's national research management committee. "Concentrations outside the gas fields were about 1.7 parts per million when we were looking inside the gas fields we found spikes up to 6.5 parts per million." "What we found by studying concentrations both inside the gas fields and outside the gas fields was elevated concentrations of methane within the gas fields," said Dr Douglas Tait, one of three scientists who conducted the study. Researchers from Southern Cross University used sophisticated equipment to measure methane emissions and their results were concerning. The CSIRO completed a study four years ago but it only focused on the coal seam gas well-heads, not the vast infrastructure of seams and pipelines that now spread throughout the Surat Basin.Ĭoal seam gas infrastructure now spreads through the Surat Basin in Queensland. How much methane is leaking from the coal seam gas fields here? "If you release enough of the gas - the methane in that gas into the atmosphere, then gas can be dirtier than coal more than about 3 per cent emissions, it is actually worse than coal if you are making electricity."Īlarming studies in the United States have detected methane emissions in some coal seam gas fields of between 2 per cent and 17 per cent. "It depends," said Mr Forcey, now a specialist researcher with the Melbourne Energy Institute at the University of Melbourne. Read moreīut evidence emerging across the globe of "fugitive" emissions from coal seam gas development is raising questions about the industry's image as relatively clean and green - the obvious transition fuel from coal-fired power to renewable energy. Gas power appears to have been bypassed in the coal v renewables debate, writes Justine Parker. Until recently, it has been viewed as less of a worry because it was presumed only tiny quantities of the gas leaked from onshore gas fields. It is a powerful greenhouse gas up to 80 times more powerful than carbon dioxide emissions that are causing most concerns about climate change.

Methane emissions gain less attention than emissions of carbon dioxide in the climate change debate, yet, when it comes to global warming, methane matters. Methane gas 'can be dirtier than coal', researcher says What the camera reveals is amazing: an invisible greenhouse smokestack venting methane into the atmosphere. "You flop it over to the infrared and there you see the invisible gas now made visible," he said. He shows me a gas vent on a ridge in the coal fields outside Chinchilla in Queensland.

"The way that it does that is it has got a special device inside that can cool down the inside of the camera to minus 200 degrees Celsius."Īt these cryogenic freezing temperatures, the special sensors in the camera can detect methane being emitted into the atmosphere. "This is a sophisticated camera, military grade, that can detect invisible gases like methane," he said, showing me the $140,000 Forward Looking Infra-Red (FLIR) video recorder. What he is looking for cannot be seen by the naked eye, or by an ordinary camera. The chemical engineer is a 35-year veteran of the oil and gas industry. It's hidden, invisible, unmeasured," he said. "We could be looking at a potential climate disaster here. Tim Forcey is searching for a concealed threat.
