Green hydrogen is often heralded in Australia’s net zero ambitions, but this paper posits that it is not viable today and won’t be in the foreseeable future. The paper examines why green hydrogen will likely remain prohibitively expensive, why projects are stalling and how the recently announced Orica subsidy exposes Australia’s strategy as untenable.

The Net Zero Australia project models pathways to net zero and other futures. This report focuses on domestic decarbonisation. It models four scenarios for the domestic system: a reference scenario, current policies, net zero 2050 and net zero extended. Modelling results and implications are presented for energy production, storage and build; and energy use, emissions...

GenCost is a leading annual economic report that estimates the cost of building new electricity generation, storage and hydrogen production in Australia to 2050. This report recognises that Australia’s future electricity system needs a mix of technologies to remain reliable, secure and flexible – with cost being just one part of the equation.

This paper assesses the two technologies leading the decarbonisation of Australia's bus fleet, finding that battery-electric buses are significantly more cost-effective and offer greater emissions reductions than hydrogen fuel-cell electric buses, particularly when powered by renewable energy.
