Environmental groups are sounding the alarm over a significant methane leak at an LNG export hub in Darwin that has been ongoing since 2006. This issue recently came to light, revealing that the leak has gone largely unaddressed for years.
The ABC reported that state and federal authorities had approved the Santos Barossa offshore gas project without fixing or replacing the leaking storage tank. This raises concerns about Australia’s ability to meet its methane reduction commitments, particularly as methane is a potent greenhouse gas.
This situation highlights the risks of depending on the industry to manage its own environmental impact. The leak originated from a large above-ground tank holding processed methane. Initially reported as a small leak in 2006, drone measurements from 2019 and 2020 showed it was leaking up to 184 kg of methane per hour. This information was delayed in reaching the authorities.
Now operated by Santos, the tank is expected to be filled again, despite it being empty for now. Both the company and regulators claim that the leak poses no immediate threat to the public. However, they also admit that it’s a moderate risk to the climate.
Methane is responsible for about 30% of global warming, making it over 80 times more potent than carbon dioxide in trapping heat, especially over a 20-year period. The extraction and processing of natural gas, such as LNG, are energy-intensive and contribute to greenhouse gas emissions. According to the International Energy Agency, addressing methane emissions is an essential step in mitigating climate change.
Australia committed to a Global Methane Pledge in 2022, aimed at reducing methane emissions by 30% by 2030. Meanwhile, the regulatory challenges in Australia hinder transparency and effectiveness in managing methane emissions from fossil fuel projects.
Besides methane, other pollutants from nearby industrial activities contribute to health risks in Darwin. For instance, emissions from the Inpex LNG plant release toxic substances that can harm air quality, leading to air pollution-related deaths. Research indicates that ground-level ozone, which forms when methane reacts with other chemicals in the atmosphere, is responsible for around 1.4 million deaths every year from respiratory and cardiovascular diseases.
The implications of the Darwin leak are part of a wider issue across Australia as other methane-emitting projects ramp up. Reports suggest that an open-cut coal mine in Queensland recently showed methane emissions were significantly higher than previously recorded.
Australia will need to take decisive action moving forward, not only to manage methane emissions effectively but also to address the broader challenge of greenhouse gas emissions. The fossil fuel industry has the power to influence the planet’s climate future significantly. Collaboration between industry and government is crucial for driving real change.
This situation emphasizes the need for urgent climate action and public accountability. As communities demand transparency and improved environmental regulations, it’s clear that the time to address these challenges is now.
