Delivering biomethane from agri-food waste with proprietary biogas upgrading and RNG liquefaction technology

Our small-to-medium-scale biomethane plants use proprietary upgrading and liquefaction technologies to deliver more efficiency than traditional large-scale facilities. Engineered by our Spanish manufacturing subsidiary, FNX, our modular, skid-mounted plants are simple to install in even the most remote sites, allowing agri-food producers to unlock value from waste and contribute to the circular economy.

Modular, membrane-based biogas upgrading system

Our biogas to biomethane upgrading technologies feature two modules:

Module 1: Pre-treatment
  • Biogas is fed into a pre-treatment container.
  • Biogas is cooled to remove excess water.
  • H2S is removed using carbon filters.
  • Volatile organic compounds are filtered.
Module 2: Compression and CO2 Removal
  • Pressure is increased via a screw compressor.
  • Gas is cooled with a condenser to remove any H2O.
  • Methane is separated from CO2 by membrane filters.
  • Biomethane is injected into the grid or used for vehicle fuel.*

Our modular, small-scale liquefaction plants are designed to be easily transported and installed in remote locations.

  • Skid mounted, fully finished designs for plug-and-play field installation
  • Simple transportation to any site via standard ISO shipping containers
  • Units include all cabling and piping with no need for pipe racks, cable trays or soil pits
  • Fully assembled and tested in-house by our manufacturing subsidiary, FNX
  • Self-contained nitrogen closed-loop refrigeration systems reduces costs
  • Grid-connected or self-generated power options allow for installation anywhere
