Australia’s Hydrogen Headstart Round 2: pricing an unindexed credit at the first stage

The Headstart Production Credit that the Australian Renewable Energy Agency (ARENA) offers in Round 2 is a rate per kilogram of hydrogen, or per unit of derivative, on each unit of eligible production for a maximum of 10 years. The applicant names it, and should base it on the commercial gap between the cost of renewable hydrogen, including a justifiable return on capital, and its sales price. It is not increased for inflation and should stay fixed over the support period, unless ARENA, at its discretion, accepts another profile. Nothing is paid before the facility is operational, and ARENA said it was unlikely to contribute to capital costs. At the expression of interest, the first of the round’s two stages, an applicant could give two figures, a target credit and an upper estimate; the upper estimate was expected to be the most it could request at the Full Application. The total production volume in the Full Application caps total ARENA funding.^{1, 2}

So for an applicant that gave an upper estimate, the allowance for inflation and cost growth, through development and up to 10 years of operation, belonged in that estimate: the credit would not rise for inflation, and the credit requested at the Full Application was expected to stay within it.

The Guidelines of 10 October 2025 put the total funding allocated for the Program at “up to $2 billion” (Australian dollars), intended for “a small number of Projects”, and let ARENA allocate more or less. They also foresaw an oversubscribed second stage: the invited applicants’ cumulative request was “expected to exceed the Total Funding Allocation”.¹ On 13 May 2026, announcing the seven projects shortlisted for the Full Application, ARENA wrote that “The Australian Government has revised the amount of funding allocated to the program in the 2026 Federal Budget to $1 billion”. Its Round 2 page, as read on 9 October 2026, still said “Up to $2 billion of funding is available”.^{4, 5}

The release is the most recent dated statement of the revision, and it speaks of the program, not of Round 2; neither it nor the Round 2 page says how much of the revised funding Round 2 can draw on. That matters to a bidder because the second stage was expected to ask for more than the Guidelines’ allocation: if the revision applies to Round 2, the same requests would compete for less.

Applications were assessed against five equally weighted merit criteria, and the credit sits inside one of them, financial viability and co-funding commitment. Under that criterion, ARENA considers the proposed credit and the total funding request, and cost competitiveness by the implied cost per kilogram of hydrogen delivered over the contract term, including capital and operating costs and excluding any concessional funding. That pulls the proposed credit two ways: the higher it is set, the larger the request this criterion weighs; the lower, the less room it leaves for cost growth the applicant must carry, unindexed, for up to 10 years.¹

As of 9 October 2026, ARENA’s funding opportunities page listed Round 2 among closed opportunities “no longer accepting applications”, in a section that says successful projects “will be publicly announced at a later date”.⁶

A project needed a new electrolysis facility, 100% powered by renewable energy from behind-the-meter generation or from surrendered eligible renewable electricity certificates created within 12 months of production or a timeframe agreed with ARENA; coal gasification or steam methane reforming with carbon capture and storage was not eligible, and all end uses, export included, were. The minimum was 30 MW of electrolysis at a single site, measured as nameplate capacity, with production in Australia; production spread across geographically diverse sites was not eligible.¹

The seven projects ARENA shortlisted range from 120 MW to 750 MW of electrolysis, in Tasmania, Queensland, Victoria and Western Australia, for end uses including methanol, ammonia, urea and alumina. All seven sit well above the 30 MW floor.⁵

ARENA’s release said only applications meeting “a high merit threshold” would be considered for funding, and that a recommendation would then go to the Minister for Climate Change and Energy for approval.⁵ Success at the Full Application brings only a non-binding Offer to Negotiate a Funding Agreement: every funding offer and payment is conditional on executing a Funding Agreement, and ARENA may withdraw or reduce an offer during negotiation.¹

No money moves at the shortlist: a shortlisted project still has to clear that threshold, negotiate under a non-binding offer and sign a Funding Agreement, and even then the credit is paid only on eligible production. Our hydrogen guide follows the same distinction, between being selected and being funded, in the European Hydrogen Bank’s auctions.

When ARENA issues an Offer to Negotiate, the applicant must provide a bid bond, in an amount ARENA confirms but “not expected to exceed $5 million”. It may be forfeited in situations that include withdrawing from negotiations or missing agreed milestones, such as Financial Close, unless ARENA extends them. The bond must come from a bank with a branch in Australia rated at least A- by Standard & Poor’s or A3 by Moody’s and, if not called, is expected to be returned at Financial Close. So the bond is at risk before any credit flows: it is expected back at Financial Close, and nothing is paid until the facility operates.¹

The Funding Agreement is expected to include upside sharing if a project materially outperforms: ARENA expects 50% of upside to be shared, which may be negotiated, with repayment capped at the total funding provided.¹ Agreeing a Knowledge Sharing Plan is a condition of funding, and ARENA’s template marks the Data Snapshots public apart from agreed exceptions: due every 6 months, 20 times, from commissioning to 10 years after, with monthly electricity, water and other O&M costs among their data. The template leaves the scope and contents of each deliverable to be developed through the Full Application stage and the Funding Agreement negotiations. If the template’s marking survives negotiation, a funded project’s monthly power, water and other operating costs would be public, apart from any exceptions agreed with ARENA.^{1, 3}

ARENA’s release on the shortlist gave applicants until early September 2026 to submit Full Applications, later than the August 2026 the Guidelines had given, subject to ARENA’s confirmation; the Guidelines mark every date of that stage as “subject to change”.^{1, 5}

The Guidelines put the decision between October and December 2026, subject to change. Projects ARENA names as successful at the decision would hold a non-binding offer and a bond to post, not a Funding Agreement.¹
