【Ten Years of Rapid Development in Chemical Engineering Equipment】China’s First Flat-Tube SOEC High-Temperature Electrolysis System from 1199 to 2023
Thread Content
Looking at the development of chemical technology over the past decade, we praise the prosperity and strength of modern China. This is just a starting point to encourage further discussion among everyone; with your participation, things will become even more interesting. [Ten Years of Progress in Chemical Equipment] – continuous updates and summaries available. Feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html. Prevention first, life above all. ----------------------------------------- On October 30, 2023, Zhejiang Hydrogen Bond Technology Co., Ltd. officially launched a series of small-scale flat-tube SOEC high-temperature electrolysis systems, the result of 3 years of research and development. The DC power consumption for hydrogen production in the electrolyzer of this system is as low as 3.6 kWh/Nm³, the electrolysis efficiency of the electrolysis system can reach 85%, and the product design has passed the EX explosion protection certification. Solid oxide electrolyzer (SOEC) electrolysis is the reverse process of solid oxide fuel cell (SOFC) power generation, and it is currently the hydrogen production technology with the highest theoretical electrolysis efficiency. At operating temperatures of 700–850°C, compared to technologies such as alkaline electrolyzers and proton exchange membrane electrolyzers, SOEC technology can save more than 30% on electricity consumption. When electrolyzing water vapor in coupling with an external heat source, the electricity consumption per cubic meter of hydrogen produced by SOEC can be reduced to 3.14 kWh/Nm?. Furthermore, this technology can also be used for co-electrolysis of H2O and CO2 to produce H2 and CO syngas. Therefore, SOEC technology is also expected to be applied in areas such as carbon dioxide recycling, electronic fuel production, and green metallurgy.
Three consecutive posts are all about electrolysis: lol
On October 30, Zhejiang Hydrobond Technology Co., Ltd. officially launched a series of small-scale flat-tube SOEC high-temperature electrolysis systems, the result of 3 years of research and development. The DC power consumption for hydrogen production in the electrolyzer of this system is as low as 3.6 kWh/Nm³, the electrolysis efficiency of the electrolysis system can reach 85%, and the product design has passed the EX explosion protection certification. #1 Regarding SOEC solid oxide electrolyzers, electrolysis is the reverse process of power generation in solid oxide fuel cells (SOFCs), and it represents the hydrogen production technology with the highest theoretical electrolysis efficiency at present. At operating temperatures of 700–850°C, compared to technologies such as alkaline electrolyzers and proton exchange membrane electrolyzers, SOEC technology can save more than 30% on electricity consumption. When electrolyzing water vapor in coupling with an external heat source, the electricity consumption per cubic meter of hydrogen produced by SOEC can be reduced to 3.14 kWh/Nm?. Furthermore, this technology can also be used for co-electrolysis of H2O and CO2 to produce H2 and CO syngas. Therefore, SOEC technology is also expected to be applied in areas such as carbon dioxide recycling, electronic fuel production, and green metallurgy. #2 Product Iteration: It is reported that, building on the research achievements of the Ningbo Institute of Materials Technology and Engineering under the Chinese Academy of Sciences, the SOEC electrolysis system series launched by HydrogenBond Technology have seen comprehensive technological advancements through 3 years of product development and 4 rounds of updates, resulting in improved quality, better prices, and enhanced after-sales service. The electrolysis power of the electrolyzer ranges from 1 to 20 kW, with a maximum hydrogen production rate of over 5.6 Nm³/h. The electrolysis system uses flat-tube solid oxide fuel electrolyzers. Compared to the traditional flat-type electrolytic cell structure, this structure has higher flexural strength and greater resistance to fluctuations in water vapor pressure ； Combined with the self-developed ceramic sealing material, it offers highly consistent sealing performance and can withstand frequent pressure changes of ±20 kPa ； The internal design of the flat-tube electrolyzer features large-sized flow channels, which facilitates heat transfer within the electrolyzer and also aids in the removal of the gases produced during electrolysis. The electrolysis system can continuously produce hydrogen by electrolyzing water vapor at a current of 5000 A/m2, with the performance of the product undergoing continuous optimization and improvement. At the same time, this electrolysis system can also operate in a mode for the electrolytic synthesis of fuel from CO2. At an operating temperature of 750 °C, CO2 and H2 are fed into the system, and it operates at a constant current density of 3000 A/m2 for nearly 2000 hours; the overall energy conversion efficiency of the electrolyzer is ≥95%. This represents one of the most advanced technical approaches for the recovery and utilization of CO2 at present.
