Biogas in New Zealand
Biogas is already produced at 20 landfills and wastewater treatment plants in Aoteoroa, where it’s burned to provide heat and power for the sites. We actually produce enough to provide around half of the country’s residential gas needs! It’s currently not injected into the gas grid; but that’s what we want to change.
Firstgas Group has partnered with Beca Engineering, Fonterra, Lion and EECA to carry out a technical study of the potential of biogas. Together we’re investigating how we can unlock the opportunity of injecting biomethane (cleaned biogas) into our existing gas network. Not only would this maximise the value of suitable compostable waste streams, but it would begin to decarbonise the gas network. And, as the volume of biogas in the grid increases, it means gas users could move to zero carbon without having to change their appliances.
This study is well underway with results due in April 2021.
