01
Up to 3 TPD
Vacuum Pressure Swing Adsorption
Our default choice for smaller plants. Uses adsorbent media to selectively capture CO₂ at elevated pressure, delivering high methane recovery and purity — a mature, dry, chemical-free process with proven reliability at smaller scale.
02
Above 6 TPD
Membrane Separation
Our preferred technology at larger scale. A dry, compact separation process based on molecule size and pressure — a physical separation with no need for scrubbing water or chemicals, and a smaller footprint that scales cleanly as your plant grows.
03
6 TPD range
Water Scrubbing
A proven option in the 6 TPD range, especially where membrane isn\’t the best fit. One of the most widely adopted upgrading methods globally, using nothing more exotic than water to separate CO₂ from methane.
04
Highest purity
Amine Scrubbing
Used where the highest gas purity is non-negotiable. A chemical process that reacts with CO₂ to hold it in solution, capable of methane purity above 99.9% — the benchmark for pipeline injection and the strictest buyer specifications.
Our default
AEM Electrolysers
Our default for most sites. AEM electrolysers are generally less expensive and more adaptable, with stack costs roughly 65% lower and catalyst costs roughly 75% less than PEM systems engineered to bring hydrogen production within reach of more projects, not just the largest ones.
Highest purity
PEM Electrolysers
Deployed where maximum purity and compact footprint matter most. PEM systems produce hydrogen at high pressure with a compact design, well suited for high-purity applications and integration with renewable energy for on-site production.
