Australia needs to decarbonise its energy supply to meet its international commitments on greenhouse gas emissions. Electricity from wind and solar can help – but how do we reduce emissions from the gas we use to warm our homes, heat water and cook dinner?

The COAG Energy Council has set up a taskforce to examine the role of hydrogen in Australia’s energy system. Hydrogen can be produced from zero-emissions sources, and can be mixed in with natural gas in pipelines today. Over time, the gas network could switch to 100 per cent hydrogen, potentially delivering abundant emissions-free energy to households and businesses.

In this Forward Thinking event Alison Reeve from the COAG Hydrogen Taskforce, Peter Harcus from Jemena Gas Networks and Craig Memery from the Public Interest Advocacy Centre joined Grattan’s Tony Wood to discuss whether hydrogen will become a key part of Australia’s energy supply.
