Biomethane

Commercial profile

Product characteristics and commercial applications

Biomethane is evaluated by its declared grade, physical form, intended commercial use and the buyer’s transaction-specific requirements. The points below are due-diligence and quotation criteria, not a representation of stock or a guaranteed specification.

• Renewable liquid or gaseous fuel identified by feedstock pathway, conversion process and finished-fuel properties.
• Density, viscosity, heating value, cold-flow, oxidation stability, water and contaminants may be decisive.
• Lifecycle greenhouse-gas intensity and sustainability status depend on recognised methodology and evidence.
• Blend limits, engine or aviation approval and national mandates vary by market.
• Road, aviation, marine or industrial energy programmes where the specific fuel is approved.
• Blending with conventional fuel under the applicable finished-fuel specification.
• Grid, fleet or corporate decarbonisation programmes supported by valid sustainability evidence.

Buyer input

Parameters normally specified by buyers

• Renewable content and feedstock pathway
• Density, viscosity and heating value
• Sulphur, water and contaminants
• Cold-flow and oxidation performance
• Lifecycle greenhouse-gas intensity

Document control

Applicable specification frameworks

• EN 14214, EN 15940, ASTM D7566 or relevant standard
• Sustainability and chain-of-custody evidence
• Certificate of analysis
• Mass-balance documentation where applicable

Execution planning

Packaging and bulk-delivery alternatives

• Bulk vessel, road tanker, rail tanker or terminal transfer for compatible liquid fuels.
• Pressurised, refrigerated, pipeline or grid delivery for compatible gaseous products.
• ISO tank or approved intermediate containment where volume and regulations permit.
• Dedicated or thoroughly cleaned equipment may be required to protect quality and sustainability claims.

Execution planning

Storage and handling considerations

• Use clean, compatible tanks and control water, oxidation, temperature and microbial risk as applicable.
• Segregate certified product and preserve mass-balance or chain-of-custody records.
• Observe product-specific shelf-life, blend and material-compatibility guidance.
• Apply the same fire, gas, pressure and environmental controls required for the physical fuel form.

Document control

Certificate of analysis and inspection requirements

• Seller or producer certificate of analysis identifying the batch, lot or cargo and reporting agreed parameters with units and test methods.
• Certificate dates, laboratory identity and sample basis must be consistent with the offered product and loading programme.
• Independent quality and quantity inspection by SGS, Bureau Veritas, Intertek or another mutually accepted inspector where contractually agreed.
• Sampling, sealed-retention samples and quantity determination by draft survey, calibrated meter, weighbridge or another agreed method.

Document control

Origin and chain-of-custody documentation

• Certificate of origin or equivalent producer, refinery, plant or mine documentation appropriate to the commodity.
• Evidence of the seller’s authority and a traceable document chain linking producer, authorised seller and transaction counterparties.
• Transport, warehouse, terminal, export and customs documents appropriate to the agreed delivery route.
• Sanctions, export-control, responsible-sourcing and destination requirements must be cleared before contract and shipment.

Execution planning

Typical logistics and Incoterm considerations

• State the applicable Incoterms® 2020 rule and the precise named port, terminal, warehouse or place.
• Confirm loading and delivery windows, nominated transport mode, capacity, route and receiving-facility compatibility.
• Allocate freight, insurance, export/import clearance, title transfer and risk transfer explicitly in the contract.
• For vessels, agree nomination, laycan, notices, loading/discharge rate, laytime and demurrage provisions.
• For land movements, confirm axle, wagon, terminal, border, dangerous-goods and appointment requirements.

Buyer input

Information required in a quotation request

• Exact product name, grade, standard, composition and acceptable tolerances.
• Required quantity, unit, shipment size, delivery schedule and contract duration.
• Destination, named place or port and requested Incoterms® 2020 rule.
• Preferred packaging, transport mode, loading window and receiving constraints.
• Required inspection company, certificates, origin evidence and regulatory documents.
• Buyer legal entity, authorised contact, intended use, KYC information and proposed payment instrument or commercial terms.

Availability and contractual basis

Specifications, documents, quantities, delivery arrangements and availability remain subject to the verified seller’s written offer and the definitive contract. Helianthus acts solely as an independent facilitator, does not hold inventory or take title to the commodity, and does not warrant availability, ownership or performance by any counterparty.
