Improve your biomethane profitability.
Proprietary hollow-fibre membranes for biomethane upgrading. Developed to unlock more capacity from your upgrader and reduce upgrading energy demand.
For upgrading OEMs, engineering partners and plant operators.
01 Why it matters
Get more from every upgrader.
For plant operators
Unlock upgrading capacity
When feedstock outgrows the upgrader, our membranes are developed to raise flow per module at the same compression, so more biogas goes through the plant you already have, where the configuration allows.
Fit your existing upgrader
Standard 4-, 6- and 8-inch module formats with end connections designed around common upgrader configurations. Replace cartridges at changeover, or run ours in parallel first.
For engineering partners
Less membrane area and energy per duty
Higher throughput per module is designed to reduce the membrane area and compression energy a given duty needs, where the configuration allows.
Designed to your gas specification
We model performance against your product specification stage by stage, including oxygen. Our R&D can develop variants for demanding gases, such as high-oxygen streams.
Our development objective is to increase gas throughput and reduce operating pressure and energy requirements where the system configuration allows.
02 Field evidence
Evidence from live biomethane sites
30%+
higher permeate flow than a commercial polyimide module
- Preproduction four-inch module
- At 15 bar feed pressure
- Comparable permeate CO₂ purity
Comparative field test on the same pretreated digester gas. For operators, higher throughput per module could mean fewer modules, or lower operating pressure, for the same biogas flow.
We can offer experimental and simulation data upon request →03 Our membranes
Materials science. Built into a module.
Inside each module, bundles of hollow fibres carry the biogas.
Carbon dioxide passes through the fibre wall faster than methane. CO₂ leaves as permeate; methane-rich gas continues as retentate. Our proprietary membrane material is engineered for that selective CO₂/CH₄ separation and built into hollow-fibre modules in standard formats.
We design the material itself, not just the module. Our R&D focuses on improving membrane permeability, selectivity and durability, and can develop variants for demanding gases.
- CO₂ · permeate
- CH₄ · retentate
04 Demonstrations
We can demonstrate. You can compare.
We can demonstrate our membrane technology in our UK laboratories and work with your technical team on a comparative demonstration using your feed gas and operating requirements.
- 01
Model your plant
Share flow, composition, pressure and product specification. We simulate our membranes in your configuration, stage by stage, and state every assumption.
- 02
Demonstrate on your gas
Send us your real biogas and we demonstrate our membranes on it in our UK laboratories, measuring the composition of each stream.
- 03
Run alongside your incumbent
Where your upgrader allows, fit a small set of our modules in parallel with your existing ones, metered separately and isolatable at any time.
- 04
Quantify the case
Measured and modelled results, kept separate, translated into capacity, energy and plant economics.
05 Looking ahead
More value from every gas stream.
Biomethane upgrading is our focus today. Separated biogenic CO₂ can be a product in its own right when it is in the right format, and our wider ambition is to apply gas separation to circular processes that turn waste-derived gases into useful energy and feedstocks. With suitable downstream processing and partners, separated CH₄ and CO₂ streams could support further fuel, chemical and other utilisation pathways.
06 Monitor AI
Connecting the material to the plant.
Our vision for Monitor AI is a connected digital twin that brings together feedstock identity, operating conditions, process simulations and measured outcomes. The aim is to help partners understand performance, compare scenarios and track the value created across the upgrading process.
- Feedstock identity
- Operating data
- Process models
- Measured outcomes
