Delorean secures $1.1 million ARENA milestone payment as SA1 construction accelerates
Delorean Corporation (ASX: DEL) has received $1.1 million (GST exclusive) from the Australian Renewable Energy Agency (ARENA), marking the second milestone payment under the Delorean SA1 Salisbury ARENA Grant. The payment brings total grant funds received to $3.8 million of the $6.08 million total funding package supporting the company’s flagship bioenergy facility at Edinburgh Parks, South Australia.
The ARENA funding, awarded under the National Industrial Transformation Program, retrospectively covers procurement, installation, and commissioning costs for critical infrastructure that will enable the facility to produce mains-grade biomethane for industrial users through the Adelaide gas network.

What is biomethane and why does it matter?
Biomethane is renewable natural gas produced from organic waste through a controlled biological process. Unlike raw biogas, which contains impurities and lower energy content, biomethane is upgraded to meet pipeline quality standards, making it directly interchangeable with fossil natural gas in existing infrastructure.
The production process involves several key stages:
- Organic waste collection: Food waste, agricultural residues, and other organic materials are delivered to the facility
- Anaerobic digestion: Microorganisms break down organic matter in sealed tanks, producing raw biogas (primarily methane and carbon dioxide)
- Biogas upgrading: The raw biogas is cleaned and purified to remove carbon dioxide, moisture, and trace contaminants
- Grid injection: The resulting biomethane meets pipeline specifications and can be injected directly into natural gas networks
For investors, biomethane represents a commercially viable renewable energy product with immediate market application. The fuel reduces waste sent to landfill whilst producing clean energy that requires no changes to existing gas infrastructure or end-user equipment.
SA1 Salisbury construction progress and key milestones
The SA1 facility is advancing toward first renewable gas production, with Stage 1 designed to process 70,000 tonnes per annum of organic waste to produce up to 210 TJ of biomethane annually. Current approvals support expansion to 125,000 tonnes per annum under Stage 2.
Construction milestones demonstrate tangible progress across structural, mechanical, and electrical systems:
| Milestone | Status |
|---|---|
| Reception shed and AD tank erection | Complete |
| Long-lead item procurement | Delivered to site |
| Tank hydrostatic testing | Underway |
| CHP unit positioning | Complete |
| HV grid connection works | On schedule |
| Biomethane upgrade unit components | Delivered |
| Tank farm slabs and earthing works | Complete |
The Combined Heat and Power (CHP) unit has been positioned to support site parasitic load requirements, whilst process equipment for ongoing shed construction has been delivered and is located in-country. Concrete slabs continue to be poured for ancillary equipment as the facility nears operational readiness.
Physical construction progress reduces project timeline risk and brings the company closer to revenue-generating operations. The delivery of all long-lead items removes a common source of delay in industrial projects, whilst successful hydrostatic testing validates the structural integrity of critical process vessels.
Secured offtake agreements underpin revenue visibility
The SA1 facility benefits from contracted revenue streams with investment-grade counterparties. Origin Energy has committed to a long-term biomethane offtake agreement (announced 8 September 2025), whilst Supagas will purchase renewable liquid CO₂ produced during the biogas upgrading process.
The combined agreements provide approximately $55 million in contracted revenue over a 10-year term, establishing a foundation of cash flow certainty as the facility transitions to operations.
Beyond these anchor contracts, SA1 is positioned to generate income from multiple sources:
- Biomethane sales
- Renewable liquid CO₂
- Carbon credits (ACCUs)
- Renewable Gas Guarantees of Origin (RGGOs)
- Liquid fertilisers
- Gate fees
Gate fees, received for accepting organic waste that would otherwise go to landfill, provide an immediate revenue stream that begins as soon as waste reception commences. Carbon credits and RGGOs offer additional value from the environmental attributes of renewable gas production.
The diversified revenue model reduces dependency on any single income source, whilst the creditworthiness of Origin Energy and Supagas as counterparties mitigates offtake risk.

What this means for Delorean’s investment case
The $1.1 million ARENA milestone payment validates Delorean SA1 Salisbury ARENA Grant progress whilst delivering non-dilutive capital that reduces the funding burden on shareholders. With $3.8 million now received of the $6.08 million total grant, government backing has provided material de-risking through both financial support and implicit endorsement of the project’s technical and commercial merit.
Construction progress positions the company for a near-term transition from development to cash-generating operations. The completion of major structural works, delivery of long-lead equipment, and advancement of grid connection activities demonstrates execution capability on a complex industrial project.
Long-term offtake agreements with investment-grade counterparties provide revenue certainty, whilst the multiple income streams from biomethane, CO₂, carbon credits, and gate fees offer downside protection if individual revenue lines underperform. Stage 2 expansion optionality to 125,000 tonnes per annum presents a pathway to scale production if market conditions support additional capacity.
The ARENA funding model, which reimburses costs retrospectively as milestones are achieved, aligns government support with demonstrated progress. This structure reduces execution risk by ensuring funding follows performance rather than preceding it.
Investment Takeaway
The milestone payment and construction progress strengthen Delorean’s pathway to first renewable gas production, with government backing, secured offtakes, and physical site advancement combining to reduce project risk as the facility approaches operational status.
