Blended 5% renewable gas is the first step on our journey to lowering carbon emissions, progressively removing carbon from our gas.
Australia is working towards a reduction in carbon dioxide (CO2) to between 26 to 28% below 2005 levels by 2030 and South Australia is working towards becoming net zero emissions by 2050.
Developing a renewable hydrogen industry will also enable further decarbonisation of other sectors as well as developing a new industry and facilitating economic growth.
If we were to blend 10% by volume across all of South Australia:
A 5% renewable hydrogen blend in Mitchell Park is the first step to lowering carbon emissions but we are pursuing more projects, aiming to blend up to 10% renewable hydrogen in South Australia and across the other regions we serve before 100% conversion.
A blend of up to 10% would help to lower carbon emissions relatively quickly without changes to appliances, pipes and meters. This can happen while larger scale, 100% conversion projects are being progressed.
Unlike natural gas or petrol, when hydrogen is burned there are no CO2 emissions.
Just like natural gas, hydrogen can be used for:
Replacing natural gas with renewable hydrogen allows us to continue using gas in our homes and businesses whilst lowering carbon emissions. Studies such as Hydrogen for Australia's Future and 2050 Energy Scenarios in the UK indicate that replacing natural gas with 100% hydrogen is cheaper than replacing with renewable electricity.
Hydrogen also has other benefits such as:
Hydrogen as renewable energy is already being pursued across Australia:
