Abstract

The substitution of traditional fossil fuels with renewable energy sources is a crucial endeavor for achieving carbon neutrality targets. However, the intermittency of solar, wind, and other renewables poses significant challenges to the power grid. Power-to-X (P2X) technologies play an essential role in enabling the efficient consumption of renewable energy. High-temperature solid oxide electrolysis cells (SOECs) to convert CO₂ offer a promising method for CO₂ conversion, allowing renewable electricity to be stored in chemical form and facilitating the resourceful utilization of carbon resources. In this paper, the mechanism of CO₂ reduction through SOECs is reviewed, two pathways for converting CO₂ to chemicals via SOECs are summarized, and the current markets and manufacturers of SOECs are elucidated. Based on this discussion and analysis, the main challenges and development directions for the large-scale application of SOECs in CO₂ conversion are further proposed.

开发用于二氧化碳转换的固体氧化物电解电池：一种关键的功率- x方法

用可再生能源替代传统化石燃料是实现碳中和目标的关键努力。然而，太阳能、风能和其他可再生能源的间歇性给电网带来了重大挑战。P2X （Power-to-X）技术在实现可再生能源的高效使用方面发挥着至关重要的作用。高温固体氧化物电解电池（SOECs）转化CO2为CO2转化提供了一种很有前途的方法，使可再生电力以化学形式储存，便于碳资源的资源化利用。本文综述了soec减少CO2的机理，总结了soec将CO2转化为化学品的两种途径，并对目前soec的市场和制造商进行了阐述。在此基础上，进一步提出了soec在CO2转化中大规模应用面临的主要挑战和发展方向。
