MELBOURNE, April 25 (Xinhua) -- Researchers in Australia is looking to scale up biomethane made from organic waste as part of efforts to ease energy pressures and reduce greenhouse gas emissions.
The study led by Australia's University of Melbourne (UniMelb) has shown how energy companies and waste management firms can safely turn organic waste, such as food scraps, sewage and animal waste, into clean gas for homes and businesses, said a UniMelb statement on Friday.
The team identified the critical specifications for optimal biomethane quality, making it more cost-effective to produce and informing the latest update of Australian Standards for use by energy producers.
The revised standard now recognizes biomethane as a natural gas equivalent, introduces new contaminant limits, and clears the path for biomethane to enter Australia's gas networks safely and at scale.
Biomethane, or renewable natural gas, comes from organic waste broken down by microbes in oxygen-free tanks. It is seen as a low-emissions alternative to fossil gas using existing infrastructure, according to the study published in the International Journal of Heat and Mass Transfer.
The current fuel crisis has strained Australia's energy system, with electric vehicle sales rising 42 percent in March, but electrification alone cannot replace fossil fuels in heavy transport and industry, researchers said. Enditem
