Delorean Earns GreenPower Stamp for SA1 Plant Unlocking Fourth Revenue Stream
Delorean secures GreenPower accreditation for SA1 Salisbury bioenergy project
Delorean Corporation (ASX: DEL) has received accreditation for its SA1 Salisbury Project under GreenPower’s Renewable Gas Certification, positioning the facility to generate Renewable Gas Guarantee of Origin (RGGO) certificates linked to its renewable gas production. The accreditation from the National GreenPower Accreditation Program — a NSW Government-administered initiative supporting renewable energy production since 1997 — validates what Managing Director Joe Oliver describes as a “first-of-its-kind facility” in the Australian bioenergy landscape. The SA1 Project is located at Edinburgh Parks in the Northern Adelaide Food Park, Salisbury, South Australia.
The accreditation represents a significant milestone for Delorean, providing third-party government-backed validation of the SA1 project’s commercial viability whilst unlocking an additional revenue stream through RGGO certificates ahead of operations commencing.

What is GreenPower’s Renewable Gas Certification?
GreenPower’s Renewable Gas Certification enables commercial and industrial gas users to match their fossil gas consumption with renewable gas certificates, effectively reducing their Scope 1 emissions. The certification covers biomethane, biogas, e-methane and renewable hydrogen, establishing a nationally recognised framework for the creation, transfer and retirement of renewable gas certificates associated with eligible renewable gas production.
Businesses purchasing RGGOs can support renewable gas injected into the network on their behalf, offsetting their traditional gas use with certified low-emission alternatives. The certification provides independent verification and ensures consistency and transparency across all Australian jurisdictions.
For investors, this voluntary market mechanism creates ongoing demand for renewable gas production whilst providing businesses with a credible, government-endorsed pathway to reduce emissions. This framework supports long-term offtake potential for producers like Delorean, de-risking revenue projections through established market infrastructure.
SA1 project specifications and revenue potential
The SA1 Edinburgh Parks Bioenergy plant is 100% Delorean-owned on Delorean-owned land and is currently in construction. Stage 1 is designed to process up to 70,000 tonnes per annum of commercial and industrial waste streams from landfill and agricultural waste, with nominal production capacity of up to 210 TJ per annum of renewable natural gas (biomethane) for export to Adelaide’s gas network. Stage 2 expansion potential exists to 125,000 tonnes per annum under current development approval.
SA1 construction progress reached 75% completion in May 2026, with waste acceptance targeted for August 2026 and first biomethane injection into the Adelaide gas network scheduled for November 2026.
Key project metrics:
- 70,000 tonnes per annum waste processing capacity (Stage 1)
- Up to 210 TJ per annum biomethane production
- 125,000 tonnes per annum potential expansion (Stage 2)
- $6.1 million ARENA grant funding (National Industrial Transformation Program)
Six revenue streams:
- Renewable Natural Gas (Biogenic Methane)
- Renewable food grade liquid CO2 (Biogenic LCO2)
- Carbon Credits (ACCUs)
- Renewable Gas Guarantees of Origin (RGGOs)
- Liquid Fertilisers
- Gate Fees
The diversified revenue model significantly de-risks the project by eliminating reliance on a single income source.
Management and industry perspectives
Managing Director Joe Oliver emphasised the accreditation’s significance as the company approaches the final stages of construction:
Joe Oliver, Managing Director
“With Delorean approaching the final stages of construction, the accreditation of the Company’s flagship SA1 Project under GreenPower’s Renewable Gas Certification scheme provides further support for advancing this first-of-its-kind facility. The certification with GreenPower confirms Delorean’s established leadership in the Australian bioenergy landscape. The Program also provides evidence of the increasing role that renewable gas will have in reducing the emissions of gas use. The establishment of GreenPower’s Renewable Gas Certification is also further evidence of GreenPower’s commitment to expanding the scope of renewable energy, and specifically renewable gas, in Australia’s energy mix.”
GreenPower Program Lead Carl Hollis highlighted the project’s demonstration of commercial-scale biomethane production in Australia:
Carl Hollis, GreenPower Program Lead
“Delorean’s SA1 project demonstrates that large‑scale biomethane production from food waste is not only possible in Australia, but ready to support the energy transition at scale. As a GreenPower accredited project, it will provide industries with a reliable, lower‑emissions alternative to fossil gas that can be used within existing infrastructure while helping cut carbon emissions.”
Strategic positioning in Australia’s decarbonisation pathway
GreenPower has stated that renewable gas will play a critical role in reaching Australia’s net zero targets by decarbonising hard-to-abate industries whilst strengthening energy security. Biomethane can be utilised within existing gas infrastructure, providing a lower-emissions alternative without requiring new distribution systems or capital-intensive infrastructure upgrades.
The SA1 Project demonstrates a circular economy model, converting organic waste to energy whilst reducing landfill volumes. Delorean’s vertically integrated approach spans design, build, ownership and management of bioenergy infrastructure, positioning the company to capture value across the entire project lifecycle.
Beyond SA1, Delorean’s national pipeline is already advancing, with the Horsley Park Bioenergy Facility in New South Wales reaching a positive Final Investment Decision in April 2026, underpinned by $30.5 million in government grants and a binding 25-year gas offtake agreement with Brickworks.
Investment thesis considerations:
- Government-backed accreditation provides credibility for future offtake negotiations with commercial and industrial customers seeking verified emission reductions
- Existing infrastructure compatibility removes adoption barriers for gas users, accelerating potential market penetration
- Construction nearing completion positions Delorean to capitalise on growing voluntary renewable gas demand as decarbonisation targets tighten

Next steps for Delorean
The SA1 Project is approaching the final stages of construction, with accreditation now secured ahead of commercial operations. The project will begin generating RGGOs upon commencement of renewable gas production and injection into Adelaide’s gas network.
With accreditation secured pre-operations, Delorean can market its RGGO capacity to prospective customers immediately upon commissioning, potentially accelerating offtake agreements and revenue commencement. The company’s position as a GreenPower-accredited facility provides a competitive advantage in negotiations with businesses seeking credible, independently verified renewable gas certificates to meet voluntary emission reduction commitments.
