Your BioLNG Development Pathway, NSW

Action plan

Confidence 0%

First: Conduct a site-specific feedstock audit to move from assumed to known manure volumes. Next: Perform a candidate route technology comparison between on-site power and BioLNG liquefaction. Then: Execute a logistics scan to identify buyers for 375 kg/day of BioLNG. Decision gate: Proceed to formal assessment only if feedstock recovery exceeds 85% of modelled input and a local offtaker is identified.

Developing this pathway in NSW

Confidence 0%

NSW currently hosts 17 matching pathway projects in public registries, including 13 with a combined published capacity of 196.5 MW. Notable regional activity includes the Malabar biomethane facility and planning for the Griffith Bio-Hub. The market context is defined by a shift toward gas network decarbonisation, though state-specific regulatory hurdles for small-scale liquefaction remain proposed rather than known.

Screening NSW Planning Requirements

• Why it matters for you: Small-scale bioenergy projects in NSW must navigate distinct land-use and environmental planning layers that differ from other states.
• Evidence needed: Applicable Local Environmental Plan (LEP) and State Environmental Planning Policy (SEPP) requirements for small-scale liquefaction.
• Next action: Initiate a pre-lodgement enquiry with the relevant local council.
• Who confirms it: Town planning consultant.

Gas Network Accessibility Check

• Why it matters for you: If BioLNG liquefaction is bypassed, the 529 Nm³/day biomethane route depends entirely on NSW network injection standards.
• Evidence needed: Pipeline proximity and Jemena/network injection specification for renewable gas.
• Next action: Request a desktop capacity study from the gas network owner.
• Who confirms it: Network engineering team.

Decision Summary

Confidence 0%

The declared objective is to investigate BioLNG production from manure generated by 600 fully housed dairy cows in NSW. The model engine ecosystem-1.0.0, operating 346.75 days per year, yields a deterministic output of 375 kg/day of BioLNG. Alternative candidate routes include 529 Nm³/day of biomethane, 641 kg/day of recoverable CO2, 94.7 kg/day of hydrogen, or 1,449 kWh/day of electricity. These figures represent potential gas pool allocations and are not additive. The transition from raw biogas to BioLNG requires specific liquefaction infrastructure which differs significantly from electricity or gas injection pathways. At this stage, commercial viability is not established as CAPEX, OPEX, and offtake terms remain unknown. The current focus is screening the technology envelope rather than verifying production.

Commercialisation screen

Confidence 0%

Commercial viability not established. The next task is the 'CAPEX and OPEX Estimation' to benchmark the 375 kg/day BioLNG output against technology costs. Current modelling excludes certificates and funding from the base case. The 641 kg/day of recoverable CO2 is a mass balance figure only; saleable CO2 potential is unknown and must not be inferred as revenue until buyer specifications are met. Similarly, the hydrogen route (94.7 kg/day) is a candidate comparison only. The lack of net electricity data after parasitic loads prevents an accurate OPEX forecast. Future commercial screens must resolve these unknowns before any investment decision is proposed.

Your next pathway decisions

Confidence 0%

The primary feedstock is manure from 600 fully housed cows. While the model suggests a BioLNG output of 375 kg/day, this assumes 100% recovery of volatile solids, which is an unverified assumption. A critical decision involves choosing between BioLNG and the electricity candidate route (1,449 kWh/day). BioLNG offers energy density for transport, yet the electricity route may align better with existing on-farm parasitic loads which are currently unquantified.

Assess BioLNG vs Biomethane Logistics

• Why it matters for you: Small-scale BioLNG (375 kg/day) requires specialised cryogenic transport; biomethane (529 Nm³/day) requires a gas grid connection. The infrastructure costs differ significantly.
• Evidence needed: Distance to nearest gas injection point versus local BioLNG fleet demand.
• Next action: Map potential local heavy vehicle users capable of taking 375 kg/day of LNG.
• Who confirms it: Logistics provider and network operator.

Verify Feedstock Collection Efficiency

• Why it matters for you: Herd size alone does not establish available feedstock; collection methods determine the actual gas yield.
• Evidence needed: Verified manure tonnage and dry matter content from the specific housing system.
• Next action: Perform a feedstock audit and waste stream characterisation.
• Who confirms it: Site operations manager and laboratory analyst.

Frequently asked questions

Can I sell the 641 kg/day of CO2 mentioned in the model?

Commercial viability not established. This is a mass balance figure; actual saleable volume depends on purification technology and regional buyer demand which are currently unknown.

Is the 375 kg/day of BioLNG a guaranteed production volume?

No, this is a deterministic model output based on 600 housed cows. Actual production depends on manure recovery efficiency and plant uptime.

How does the electricity alternative compare to BioLNG?

The model suggests an alternative of 1,449 kWh/day. This route avoids liquefaction costs but requires a different infrastructure set and grid connection.

Why is funding excluded from the base case?

To establish the fundamental commercial viability of the technology route before relying on external subsidies or certificates.
