Delorean Hits 75% Build on Australia’s First Grid-Connected Biomethane Plant
SA1 bioenergy facility hits 75% completion as Delorean stays on schedule for November gas injection
Construction of Delorean Corporation’s (ASX: DEL) first 100%-owned SA1 Salisbury Bioenergy Facility at Edinburgh Parks, South Australia has reached 75% completion, with the project on track for two key milestones: waste acceptance in August 2026 and first biomethane injection into the Adelaide gas network in November 2026. To mark the progress, Delorean hosted an investor site tour on 22 May 2026, offering attendees a first-hand view of construction scale and activity. Management describes SA1 as the template project for the company’s broader national build/own/operate rollout.

What’s happening on the ground right now
All major equipment has been ordered, with the majority already delivered to site. Construction is advancing across multiple workstreams simultaneously, with civil, mechanical, and site infrastructure works all progressing towards completion.
Key workstream statuses as at the announcement date:
- Civil works are substantially completed, with asphalt completed and structural foundations largely advanced across the site
- Major process and mechanical equipment has been installed, including key pre-treatment and compression systems, with additional equipment currently in transit
- Site building works are progressing, with cladding and weighbridge installation about to commence, followed by finishing and fit-out works
- Electrical installation is scheduled to commence in mid-June 2026, alongside installation of the flare, booster, LCO₂ system, and BMU blower
- The Low-Pressure Injection Skid is ready for delivery to site, enabling biomethane injection into the Australian Gas Infrastructure Group (AGIG) gas distribution network in South Australia
- Zero lost time injuries recorded to date across the construction programme
- GreenPower accreditation activities are progressing to support the renewable energy certification pathway
Safety Performance
Zero lost time injuries have been recorded to date at the SA1 construction site, reflecting the operational discipline Delorean is maintaining across this flagship project.
What SA1 will produce at full operation
SA1 will process organic waste through anaerobic digestion, a biological process where microorganisms break down organic material in the absence of oxygen to produce renewable gas. At full operation, the facility will accept 70,000 tonnes per annum of organic waste from commercial, industrial, and municipal sectors in Adelaide’s metropolitan area.
The facility is positioned to generate six distinct revenue streams:
| Product | Volume / Output | Buyer / Pathway |
|---|---|---|
| Renewable Natural Gas (biomethane) | 210 TJ per annum | Long-term offtake to Origin Energy for industrial customers; exported into Adelaide gas network via AGIG |
| Biogenic food grade liquid CO₂ | 6,000 tonnes per annum | Not specified in announcement |
| Australian Carbon Credit Units (ACCUs) | Volume not quantified in announcement | Environmental credits |
| Renewable Gas Guarantee of Origin (RGGO) Certificates | Volume not quantified in announcement | Renewable energy certification |
| Biofertiliser | Volume not quantified in announcement | Emerging agricultural market |
| Gate Fees | Derived from processing 70,000 tpa of organic waste | Commercial, industrial, and municipal sectors |
According to the announcement, SA1 will be the first facility in Australia to export biomethane into the gas network from processing commercial and industrial organic waste streams.

SA1 as the blueprint — what comes next for Delorean’s national rollout
SA1 is explicitly described as a template for the rollout of Delorean’s pipeline of shovel-ready and near-term build/own/operate facilities across Australia, replicable in terms of capacity, organic feedstocks, biomethane and liquid CO₂ production volumes, and the generation of ACCUs, RGGOs, and biofertiliser.
The company’s next two facilities, NSW1 and VIC1, are expected to enter construction in CY2026. Delorean brings an established track record to this rollout, having built four award-winning commercial-scale facilities of equivalent capacity for third parties in Australia and New Zealand since 2014, most recently for Yarra Valley Water in Victoria, which the company is currently operating.
At SA1 itself, Stage 2 expansion potential is already secured, with development approval in place for an extension to 125,000 tonnes per annum (up from the current 70,000 tpa Stage 1 capacity).
For investors, each construction milestone at SA1 reduces execution risk across the broader pipeline. The closer the facility moves towards commissioning, the more clearly the replicable model is validated for NSW1 and VIC1.
Four milestones investors should watch:
- Electrical installation commencing — mid-June 2026
- Waste acceptance at SA1 — August 2026
- First biomethane injection into the Adelaide gas network — November 2026
- NSW1 and VIC1 entering construction — CY2026
