Biogas Upgrading
Turn raw biogas into grid-quality biomethane with stable removal of CO₂, H₂O, VOCs, NH₃ and terpenes
How It Works
Step-by-step
Laminol® removes H₂S, Hybrisol® absorbs CO₂, water, NH₃, VOCs mercaptans and terpenes, the regenerator releases clean CO₂, and a small polish finalizes grid-quality biomethane.
Characterization
We characterize the raw biogas in flow, CH₄/CO₂ ratio, H₂S, NH₃, VOCs/terpenes, moisture, temperature/pressure. This lets us adjust the process parameters downstream to align the biomethane production spec with your grid/buyer limits.
Protect & condition (H₂S)
Low-pressure H₂S removal. If sulphur is present, Laminol® removes H₂S at low pressure using a biodegradable scrubbing fluid that’s re-used. It rides through H₂S peaks, cutting corrosion and protecting solvents, membranes, and cold ends in the downstream biogas purification train.
Absorption (Hybrisol®)
Hybrisol® applies absorption to remove CO₂, co-removing NH₃, VOCs and terpenes, and dry the gas. Because capture is chemistry-driven, performance stays stable through day-to-day feed swings.
Outcome: grid-quality biomethane with ultra-low methane slip and a low dew point.
Regenerate & recover (CO₂)
The solvent is regenerated in a closed loop with efficient heat recovery, keeping operating cost predictable and minimizing losses. The co-product is a clean CO₂ stream that can be buffered or routed to storage/liquefaction depending on your site’s plan.
That CO₂ can support horticulture, beverages, or e-fuel routes, or sit as future upside.
Meter, QA, inject
Online analyzers (CH₄/CO₂, dew point, O₂), fixed sampling points, and calibrated meters produce a single certificate pack for buyer or grid acceptance.
All instruments alarm to your DCS/SCADA with clear data for export, ensuring biomethane production remains both auditable and hands-off for operators.
Benefits
Benefits for Biogras Upgrading
Biogas upgrading delivers more than just cleaner gas, it transforms operations, compliance, and commercial potential.
Higher methane concentration & consistent quality
Upgrading raw biogas ensures that methane levels are enriched to biomethane-grade standards, typically reaching 95% or higher concentration. This consistency guarantees that your output always meets the specifications required for injection into natural gas grids, fueling vehicles, or supplying industrial processes. By removing fluctuations in gas composition, you avoid the risks associated with variable quality, such as equipment damage or regulatory penalties.
Consistent quality also makes it easier to plan operations and secure long-term offtake agreements. Buyers and utilities place high value on reliability, and with stable biomethane you can position yourself as a dependable partner. This not only improves your market access but also builds confidence in your operation’s ability to deliver on sustainability commitments.
Reduced operating disruptions
Raw biogas contains corrosive and abrasive compounds that shorten the lifespan of membranes, engines, and compressors. By upgrading and removing these contaminants, equipment experiences less wear and tear, reducing the risk of unscheduled downtime. Cleaner gas protects sensitive parts, lowers the likelihood of shutdowns, and extends maintenance intervals, which saves both time and money.
Minimizing disruptions improves overall plant productivity and helps keep your output stable even during periods of heavy demand. This reliability is crucial when meeting offtake contracts or supplying energy to critical processes. Over time, reduced downtime not only lowers operational costs but also enhances the financial return on your upgrading investment.
Lower carbon intensity of operations
Switching from fossil natural gas to upgraded biomethane directly reduces the carbon footprint of your operation. Each cubic meter of biomethane displaces fossil energy, cutting greenhouse gas emissions and lowering overall carbon intensity. This contributes to national and corporate decarbonisation targets, helping your facility stay aligned with both regulatory requirements and voluntary sustainability frameworks.
In addition to climate benefits, upgraded biomethane also improves local air quality by reducing pollutants like sulphur compounds and particulates. The result is a measurable environmental advantage that benefits surrounding communities while demonstrating your commitment to responsible energy production. This combination of global and local impact makes biomethane a powerful tool in sustainability strategies.
Flexible integration with existing infrastructure
Biomethane produced through upgrading is fully compatible with existing energy infrastructure. It can be injected into natural gas pipelines, compressed for use as vehicle fuel, or supplied directly to industrial heating systems. This flexibility makes it easy to integrate without requiring major redesigns or costly new installations.
Because biomethane is interchangeable with natural gas, it also provides operators with a competitive edge. You can access diverse markets, from utilities to transportation fleets, with the same product. This adaptability reduces dependence on a single revenue stream and ensures long-term resilience, even as market conditions change.
Future-proofed investment
A modular upgrading system ensures that your investment grows with your business. As feedstock volumes increase or regulations tighten, you can expand capacity or add additional treatment stages without replacing the entire system. This flexibility makes upgrading not just a solution for today, but a strategic investment for the future.
Future-proofing also protects you against regulatory uncertainty. As emissions standards evolve and renewable gas markets expand, facilities with adaptable upgrading systems can meet new requirements without major overhauls. This gives you a competitive advantage while ensuring that your plant remains compliant and financially viable in the long term.

All frequently asked questionsWe can deliver biomethane that meets EU pipeline injection standards and/or vehicle fuel specifications, depending on your target market. Our polishing steps remove moisture, siloxanes, H₂S, ammonia and other traces to align with legal limits. After commissioning, we verify quality via gas chromatographs and independent lab testing to ensure you meet required purity, Wobbe index, and methane content.
By beginning with thorough gas analysis and feedstock assessment, we understand the variability in your raw biogas (organic composition, moisture, contaminant levels). The system is configured with flexible pretreatment stages and modular separation options that can adjust to these variations. Together with ongoing monitoring, you’ll get stable biomethane output even in changing conditions.
Payback periods generally range from 2 to 5 years, depending on biogas flow, local energy costs, and desired gas specifications. Operating costs are carefully managed via low maintenance design, durable components, and minimal chemical/solvent use in pretreatment or polishing. Savings also come from reduced waste management costs (less emissions, fewer backups) and from premium pricing of purified biomethane.
