选择哪种技术将二氧化碳直接电化学转化为化学品？

电化学将二氧化碳转化为有用的化学物质，如一氧化碳（CO），是一种很有前途的方法，可以将工业化学品的生产与化石燃料的使用分离开来。固体氧化物电解，用于Topsoe的eCOs™technology, stands out as particularly attractive for wider adoption due to the very high conversion efficiencies, even at industrially relevant production rates.

The chemical industry of today is largely dependent on fossil fuels and a major emitter of CO₂and other greenhouse gases. Oil, gas, and coal are used both as feedstock and as fuel to power the chemical processes.

Since the world is attempting to curb its CO₂footprint, emissions from the chemical industry are under increasing scrutiny. There is a growing interest both from policymakers and from the industry to adopt new, less CO₂-intensive processes for the production of chemicals.

Electrolysis is an enabling technology for decoupling the production of industrial chemicals from fossil fuels and CO₂emissions. By combining electrolysis with low-carbon energy sources, water and CO₂can, depending on the carbon source, be converted into chemical feedstock with a minimal or even negative carbon footprint. If successfully deployed at scale, CO₂electrolysis technologies have the potential to radically change the way specialty and commodity chemicals are produced.

有许多新兴的公司₂electrolysis technologies out there, so the question arises – which one to use?

Topsoe has recently published ascientific review paperin the Journal of the Electrochemical Society, trying to answer this question. In the paper, three competing CO₂electrolysis technologies - low-temperature electrolysis from aqueous solutions, molten carbonate electrolysis, and solid oxide electrolysis - were directly compared using common figures-of-merit.

Based on the analysis, CO₂固体氧化物电池电解是目前最有效、最成熟的CO制CO电解技术₂, outperforming aqueous electrolysis technologies by a wide margin regardless of the choice of performance metric.

Topsoe独特的eCOs™ 基于固体氧化物电解技术的超高纯CO现场生产解决方案具有成本竞争力。两个full-si Topsoe签署租赁协议ze commercial plants, each with a capacity of 96 Nm³CO per hour, with Delille Oxygen Co. The plants will be commissioned later this year.

Onsite CO generation is a significant development for the pharmaceutical, metallurgy, electronics and specialty chemicals industries that use carbon monoxide in their production processes. The eCOs™ technology ensures security of supply, eliminates the need for transporting the hazardous gas, and drastically reduces costs related to storage, rentals, and connections.
