To support scheme development and facilitate effective co-design, the Clean Energy Regulator (CER) in partnership with the Department of Climate Change, Energy, the Environment and Water (the Department) is conducting Guarantee of Origin (GO) trials.
The GO Midway Report is a summary of findings from phase one of these trials.
Phase one of the GO trials, running through the first half of 2022, focused on scheme settings and design, with an aim to ensuring the scheme has integrity and is practical, minimising administrative burden as well as testing the emissions accounting methodologies set out by the International Partnership for Hydrogen and Fuel Cells in the Economy's (IPHE) Working Paper.

Midway Report highlights
Phase one of the trials involved 19 hydrogen producers and stakeholders using three major production pathways: electrolysis, steam methane reforming and coal gasification.
The hydrogen industry in Australia is emerging, with a significant pipeline of announced projects but few operational commercial scale hydrogen producers. The GO trials brought together stakeholders operating some of Australia's most progressed hydrogen projects to test design elements for a GO certification scheme, including metering approaches, reporting frameworks and emission intensity calculation methods.
Trial participants reaffirmed that commercialisation would be aided by a high integrity, government-backed GO scheme that can:
- demonstrate emissions credentials to hydrogen buyers
- provide market certainty
- underpin commercial arrangements.
Several trial participants successfully used the Hydrogen Production Emissions Calculator, developed by the CER with GHD, to estimate well-to-gate emissions for their hydrogen projects, applying methodologies in line with IPHE guidelines. Results and feedback from trial use of the GO trial calculator will provide a valuable base to refine and extend GO emissions accounting approaches.
