氢is an essential chemical, already today. However, hydrogen is quickly becoming even more important, as chemical companies, refiners, and new players around the world are looking to build attractive business cases for low-carbon fuels and chemicals. To achieve this, a crucial point is the ability to produce green hydrogen from electrolysis of water with no carbon emissions – at a competitive price point.
通过电解产生绿色氢。该过程使用电力来分割水并产生氢气。在绿色氢气的情况下，电力来自可再生源源，如风力涡轮机，太阳能电池板或水电。电解过程不会发出碳或有害物质。
目前少于0.1％的氢来自水电解。现在，随着可再生电力的可用性增加，成本下降，绿色氢气的兴趣蓬勃发展。
SOEC - the most efficient form of electrolysis today
Topsoe has chosen to focus on the most efficient electrolysis technology available today. Our high-temperature SOEC – solid oxide electrolyzer cell – deliver up to 30% more green hydrogen from the same amount of renewable electricity, compared to standard technologies like PEM and alkaline electrolysis. The superior efficiency stems from the fact that the SOEC works at temperatures above 700 degrees Celsius, which sets it apart from standard electrolysis technologies.
We deliver the SOEC electrolysis unit as a stand-alone unit with power and gas connections. Our modular design allows for flexibility in plant size. The facility is fully automated with a user-friendly interface.
Electrolysis of CO2from carbon capture
Not only does the SOEC eliminate carbon emissions from the production of hydrogen, it can even electrolyze CO2from carbon capture (CCUS) and further reduce emissions.
CO.2can be captured from waste incineration, power plants, cement plants and industrial facilities. When electrolyzed with the SOEC, CO2is reduced to CO, also known as synthesis gas or syngas. Syngas is used to produce a variety of chemicals and fuels and is usually produced from natural gas. In other words; the SOEC makes it possible to replace fossil natural gas with captured CO2and avoid releasing ‘new’ carbon into the atmosphere.

SOEC如何工作？
SOEC或固体氧化物电解槽单元是一种陶瓷电池，用于分离水分子（H.2O) into hydrogen (H2) and oxygen (O2). It basically consists of three parts: an anode, a cathode and an electrolyte. At the cathode, water molecules are split by a reduction reaction into hydrogen and oxide ions, the oxide ions are transported through the electrolyte to the anode where they are oxidized into oxygen.
SOEC在700摄氏度高于700摄氏度的温度下工作，这使得它比标准电解系统更有效。CO.2can also be electrolyzed in the SOEC. In this process, the CO2is reduced to CO with O2as a byproduct.
SOEC主要由金属壳体中的丰富和低成本的陶瓷材料构成。使用罕见的金属或冲突矿物质。
