Biomethane
Biomethane
Renewable Gas as a Service: Biomethane is supplied directly to customers under long-term offtake agreements.
Boiler Fuel Decarbonization: Replace HFO, coal, or fossil gas in industrial boilers.
Liquid Biomethane (Bio-LNG): High-density, portable green fuel for SMEs and off-grid industries.
Export & ESG Alignment: Supports compliance with RE100, CBAM, and Net Zero targets.
Fuel supply for industrial boilers (gas or liquid form).
Centralized Bio-LNG hubs for industrial estates and SMEs.
Green transport fuel for logistics fleets.
Carbon credit opportunities under global standards.
Feedstock mix: Biogas sourced from Napier Grass silage, livestock manure, food waste, and agro-industrial residues (cassava pulp, palm EFB, etc.).
Input volumes: A 1,000 Nm³/hr biomethane plant typically requires 3,000–3,500 tons/month of Napier Grass or equivalent organic waste streams.
Contracts: Long-term contract farming of Napier Grass plus partnerships with municipalities and agro-industries ensure year-round supply.
Diversification: Multi-feedstock sourcing reduces seasonal risk and stabilizes gas quality.
Processes used: Pressure Swing Adsorption (PSA), Water Scrubbing, or Membrane Separation depending on site conditions.
Output quality: 96–99% CH₄ content, equal to fossil natural gas.
CBG (gas form): Direct injection into pipelines or distribution via tube trailers.
Bio-LNG (liquid form): Cryogenic liquefaction at -160°C for high-density storage and long-distance transport.
Efficiency: 90–95% methane recovery from raw biogas; <0.5% methane slip with advanced units.
Biogas collection: From digesters attached to waste treatment facilities or dedicated biogas plants.
Pre-treatment: H₂S removal, drying, and pre-compression before upgrading.
Logistics:
CBG: Distributed via pipelines where available, or tube trailers for industrial users.
Bio-LNG: Transported by cryogenic trucks to factories, SMEs, or fueling stations.
QA protocols: Continuous online monitoring of CH₄, CO₂, H₂S, and O₂; certificates of quality for every batch.
Traceability: Blockchain-ready reporting of feedstock origin and gas quality, ensuring CBAM alignment.
CBAM compliance: Biomethane is fully recognized as a renewable fuel under CBAM and RE100 frameworks. It directly reduces Scope 1 emissions by replacing fossil natural gas or HFO in boilers.
Methane reduction: Captures methane that would otherwise escape from manure lagoons or landfills, providing large GHG benefits.
Carbon credits: Eligible for issuance under T-VER, Verra, or Gold Standard.
Community benefits:
Farmers earn steady income from Napier Grass and residues.
Municipalities reduce waste disposal costs.
Local air and water quality improve by diverting waste from burning or open dumping.
Land footprint: 10–20 rai depending on capacity and whether Bio-LNG is included.
Main facilities: Biogas upgrading unit, compressors, storage tanks (CBG), cryogenic liquefaction unit + LNG tanks (for Bio-LNG).
Utilities: Power for compressors, water for scrubbing (if applicable), and nitrogen for cooling cycles.
Logistics interface: Truck loading/unloading bays, weighbridges, and access roads for safe fuel distribution.
Bio-LNG liquefaction: Add-on for clients needing long-distance distribution or liquid fuel for boilers/transport.
CHP integration: Use part of the raw biogas for onsite electricity/heat while upgrading the rest.
BECCS potential: Capture the pure CO₂ stream from upgrading (up to 45% of raw biogas volume) for food/beverage, green methanol, or permanent storage — enabling negative emissions.
Hybrid projects: Combine biomethane supply with direct private PPA, offering both electricity and boiler fuel to estates and factories.
