• Biomethane and hydrogen formally recognised as new fuel types under NGER Scheme
• Companies can now use Renewable Gas Guarantee of Origin (RGGO) certificates to reduce Scope 1 emissions
• Updated AS 4564:2025 standard expands oxygen levels and contaminant thresholds for biomethane injection

Delorean Corporation Ltd has welcomed significant recent changes to the Australian Standards and National Greenhouse Energy and Reporting (NGER) Scheme that will deliver major advantages for the company's supply of renewable gas in Australia. The changes formally recognise Delorean's biomethane as a natural gas equivalent and enable companies to use Renewable Gas Guarantee of Origin (RGGO) certificates for injected biomethane to reduce their Scope 1 emissions. Under the NGER Scheme amendments effective from 1 July 2025, biomethane and hydrogen are formally recognised as new fuel types, supporting market-based emissions accounting. Companies using RGGO certificates for injected biomethane will be able to reduce their Scope 1 emissions, with first reports due by 31 October 2026. This change unlocks additional certainty and value on Delorean's renewable gas and RGGO revenue streams. Additionally, the updated AS 4564:2025 standard now permits oxygen levels up to 1% mol in low-pressure distribution pipelines, compared to the previous 0.2%, and defined contaminant thresholds tailored to biomethane, minimising the need for excessive purification and enabling cost-effective injections. Delorean expects these changes to significantly improve purification and compliance processes, positively impacting the company's projects and execution timelines. Delorean's biogas portfolio is advancing towards full pipeline injection, GreenPower integration, and rapid upscaling aligned with the updated standards. These regulatory changes provide long-awaited certainty, reduce investment risk, and support accelerated commercial project rollout.
