Tiny Materials, Big Impact on Gas Emissions

MOFs promise cheaper capture for scattered gas emissions

18 Mar 2026

In Alberta’s gas fields, much of the carbon problem comes in small pieces. Thousands of compressors hum across the province, each emitting too little carbon dioxide to justify large capture plants, yet too much to ignore. A new project near Edson aims to close that gap.

CarbonQuest, a carbon-capture firm, has signed its first Canadian contract with Tourmaline Oil, the country’s largest gas producer. Announced on February 12th, the scheme will attach a modular capture unit to a compressor at the Banshee facility. It is the company’s first deployment in Canada and its first use on a natural-gas compression engine. It also marks the debut of metal-organic frameworks (MOFs), supplied by Captivate Technology, within CarbonQuest’s systems.

MOFs are porous, engineered materials that trap carbon dioxide more efficiently than the liquid amine solvents long used in industry. They require less energy to operate, making them better suited to smaller, dispersed sources of emissions. By fitting these materials into compact units that bolt onto existing exhaust systems, the project avoids the need for large, centralised facilities.

That distinction could prove important. Canada’s Western Sedimentary Basin is dotted with compressor stations whose emissions fall below the threshold of conventional carbon-capture projects. Distributed systems, if economical, offer a way to aggregate meaningful reductions from this neglected tier of infrastructure.

The Banshee project, costing C$4.1m, is backed by Alberta’s Emissions Reductions Alberta and the Natural Gas Innovation Fund. Captured carbon will be stored underground using the province’s established sequestration network. Tourmaline has pursued similar efforts since 2021 as it seeks to reduce its emissions intensity.

The promise is not just technical but economic. If MOFs can lower costs as hoped, they may broaden the range of viable capture sites. Yet much depends on performance in the field, where reliability and maintenance often frustrate new technologies.

Should the system meet expectations, it may offer a template for replication across Alberta’s compressor fleet. That would not eliminate emissions from gas production. But it could make a previously inconvenient source of pollution easier and cheaper to tackle.
