Delorean’s SA1 Bioenergy Project Accredited for GreenPower Renewable Gas Certificates

Delorean's (ASX: DEL) 100%-owned SA1 Salisbury bioenergy project has been accredited under GreenPower’s Renewable Gas Certification, making the South Australian facility eligible to create Renewable Gas Guarantee of Origin or RGGO certificates linked to renewable gas production.

That matters because the announcement is not about adding new plant capacity, but regarding a regulatory step that supports one of the project’s planned commercial pathways as SA1 moves through construction toward targeted commissioning milestones later in 2026.

Under the GreenPower framework, renewable gas output from an eligible facility can be linked to certificates that are created, transferred and retired within a nationally recognised system.

Delorean said the certification is administered by the NSW Government and operates across Australian jurisdictions, giving SA1 access to an independently recognised framework rather than relying on bilateral claims about renewable gas attributes.

The company did not disclose expected RGGO volumes, certificate pricing or any forecast revenue contribution from the scheme.

On that basis, the significance of today’s update is best understood as commercial and regulatory de-risking around a stated revenue stream, rather than a quantified financial uplift.

What SA1 Actually Is

The SA1 Salisbury project is fundamentally a waste-to-energy project, located on land owned by Delorean at the Northern Adelaide Food Park in Edinburgh Parks.

Stage 1 is designed to take up to 70,000 tonnes per annum of commercial and industrial waste streams that would otherwise go to landfill, along with agricultural waste, and process that material through anaerobic digestion.

That process produces biogas, which is then upgraded into biomethane suitable for injection into the gas network, according to the company.

Delorean has outlined expected Stage 1 renewable natural gas output of 210 terajoules per annum, and has also flagged a possible Stage 2 extension that could lift waste diversion capacity to 125,000 tonnes per annum.

The facility is intended to act as a template for broader rollout across the company's development pipeline, including NSW1 and VIC1, which it expects to enter construction in calendar 2026.

Biomethane from SA1 is intended to be injected into the Adelaide gas network under a long-term offtake agreement with Origin Energy (ASX: ORG) for industrial customers that covers supply of up to 200 terajoules of biomethane.

Numbers and Project Detail

Today’s accreditation applies under a scheme that covers biomethane, biogas, e-methane and renewable hydrogen.

Delorean said SA1 Salisbury has now been approved to participate in the Renewable Gas Certification program and is eligible to generate RGGO certificates associated with renewable gas produced by the facility.

The company has consistently described SA1 as a multi-product and multi-revenue project, citing potential revenue streams including renewable natural gas, biogenic LCO2, Australian Carbon Credit Units (ACCUs), RGGOs, liquid fertilisers and gate fees.

Government support is already attached to the project, with a $6.1 million grant received from the Australian Renewable Energy Agency (ARENA).

What to Watch Next

The immediate focus remains execution.

Delorean’s last construction guidance pointed to waste acceptance in August 2026 and first biomethane injection in November 2026, so those dates are the clearest near-term milestones against which SA1 can be assessed.

The next step beyond accreditation is actual certificate creation.

Eligibility under GreenPower’s Renewable Gas Certification is now in place, but certificate generation depends on the project being commissioned and producing renewable gas that can be verified under the scheme.

Delorean completed a share purchase plan on 27 May that raised $0.75 million, below the initial $2.2 million target, although the company said at the time there was no immediate intention to place further shares to cover the shortfall.

Against that, Delorean also received a $5.76 million FY2025 Australian R&D Tax Incentive cash refund in May, which provides additional liquidity support.

Certification Helps, Delivery Still Matters

Today’s announcement strengthens the commercial framework around Delorean’s SA1 project by confirming eligibility for GreenPower renewable gas certificates, an outcome that supports the project’s stated multi-stream revenue model.

But the practical value of that accreditation still depends on SA1 reaching its construction and commissioning milestones, producing saleable biomethane, and operating into certificate markets where pricing and demand have not yet been disclosed.

There are also broader uncertainties that have not been quantified, including construction and commissioning risk, the timing of first gas production, and market risk around certificate demand and pricing.

Even with regulatory approval in hand, the value of RGGOs depends on the volume of saleable renewable gas produced and the terms available in certificate markets.

For readers tracking the story, the main proof points from here are straightforward: whether SA1 stays on schedule, whether biomethane is injected into the network as planned, whether RGGO generation begins after commissioning, and whether Delorean provides more detail on the commercial contribution of certificates compared with gas sales, ACCUs, gate fees and other by-products.
