CO Production decarbonized

Convert CO₂ into carbon monoxide using Topsoe’s eCOs™ electrolysis technology

Why Topsoe leads in Carbon Monoxide

High efficiency

Topsoe’s CO process delivers industry-leading energy efficiency using advanced reforming technology.

Flexible feedstocks

It handles a wide range of hydrocarbon feedstocks—including natural gas, LPG, and naphtha—ensuring operational flexibility.

Proven performance

With over 100 licensed units worldwide, Topsoe’s CO technology is a trusted solution in both gas and liquid feed applications.

Putting captured CO₂ to work for you

Topsoe eCOs™ (electrolytic carbon monoxide solution) enables safe, efﬁcient and reliable CO production right on site and directly from CO₂. Built on a scalable, modular design, eCOs™ can meet the needs of almost any facility that uses CO in its processes, regardless of industry or size.

eCOs™ CO₂ electrolysis offers major beneﬁts over traditional forms of CO sourcing, especially when decarbonization is high on the agenda:

Lets you dispose of CO₂ while producing CO

Highly efﬁcient electrolyzer technology for a fast ROI
Built to your capacity and purity needs up to 99.995%
Field-proven electrolysis for large-scale production
Supported by expert Topsoe services

Introducing Topsoe eCOs™

Centered on Topsoe’s proven SOEC electrolysis technology – powered by electricity alone – a Topsoe eCOs™ installation can convert virtually 100% of your captured CO₂ feedstock to CO. Each installation is built to give you the exact amount and purity of CO that your process requires – up to 99.995 vol%. The result is the right CO for your operation with signiﬁcantly reduced carbon emissions.

eCOs™ is an exceptionally efﬁcient method of CO production thanks to a conversion process that is more direct and simpler than other methods. And Topsoe’s expert ﬁeld and advisory services are available to; support your installation from planning to decommissioning at the end of its lifecycle.

Your eCOs™ installation

An eCOs™ installation consists primarily of at least one SOEC electrolyzer section and a gas puriﬁcation section. CO₂ is fed into the electrolyzer, which converts the CO₂ into a CO-rich gas. This gas is led into the puriﬁcation section, which removes remaining CO₂ to achieve the purity your process requires. The removed CO₂ is fed back into the electrolyzer and used as additional feedstock, while the puriﬁed CO is sent to storage. Air or CO₂ is used as ﬂush gas on the oxy side of the electrolyzer and exits in an oxygen-enriched state.

Why SOEC electrolysis

Simpler, more straightforward and more predictable than traditional methods, SOEC converts CO₂ to CO with no need for fossil fuels but only electricity. In fact, SOEC is the only electrolysis technology suitable for efﬁcient CO₂ to CO conversion and has also achieved a higher TRL compared to low-temperature electrolyzers.

Why consider eCOs™ for CO production?

CO₂ electrolysis offers major benefits over traditional forms of CO sourcing, especially when decarbonization is high on the agenda.

Sell your CO₂ as CO

If you produce excess CO₂, converting this to CO and selling the end product to other facilities can help you decarbonize while generating a new revenue stream.
