Cleaner and greener
Renewable gas is a key part of Australia’s low carbon future. At AGIG, we’re investing in the long-term interests of our customers and the environment.
Energy in Australia is changing
The Australian energy sector is undergoing a period of rapid change. The need to reduce carbon emissions presents a number of challenges, particularly with intermittent renewable electricity sources like wind and solar generation now a growing part of the overall energy mix.
Gas is essential to our economy and modern lifestyles, providing nearly a quarter of Australia’s total energy supply. Although natural gas is currently cleaner than electricity delivered by the grid, there’s more we can do to help lower emissions, while also contributing to energy security and ensuring costs remain as low as possible.
A low carbon future
The Australian Government has committed to meeting a carbon emissions reduction target of 26 to 28% below 2005 levels by 2030. We’ve made progress in reducing emissions from the electricity sector, but there’s still a way to go to meet our targets.
While increased uptake of renewable electricity generation is important, it’s not the only solution. Australia needs to focus on large-scale decarbonisation of its entire energy supply, including electricity, gas and transport if we’re to meet our emission targets.
The gas sector’s vision is to be near zero carbon by 2050. We can achieve this by using carbon-free or carbon-neutral gases such as hydrogen in place of natural gas.
The most common forms of carbon neutral or zero carbon fuels are hydrogen and biogas, also known as biomethane. Biomethane can make use of landfill or agricultural and forestry waste to produce a net-zero emissions fuel.
Hydrogen is the most abundant element in the universe. When burned, hydrogen produces only water and energy – no carbon. Hydrogen can be produced cleanly through:
• Splitting water into hydrogen and oxygen using renewable electricity through a process known as electrolysis
• Splitting natural gas into carbon and hydrogen through a process known as Steam Methane Reforming, and capturing the carbon dioxide
• Gasifying coal to produce hydrogen and carbon and capturing the carbon dioxide
Our existing gas networks are already suitable to transport biomethane and blends of hydrogen with natural gas. In South Australia we’re investing in an innovative energy project known as Hydrogen Park South Australia. Hydrogen Park South Australia will produce hydrogen and provide a 5% renewable gas blend to nearby homes and businesses.
