e-WaGS: Efficient Water Gas Shift Technology for Low-Carbon Electric Power Generation from Fossil Fuels

综合气化联合循环与二氧化碳捕集与封存（IGCC-CCS）是一项独特的低碳发电技术，因为它生产氢作为脱碳燃料。水煤气转换（WGS）反应是IGCC-CCS过程中的关键步骤，在该过程中，燃料气化产生的一氧化碳与蒸汽反应产生氢气和二氧化碳。最先进的技术包括在传统的固定床反应器中使用催化剂，该反应器需要高水平的多余蒸汽才能正常工作。该项目的目标是找到一种创新的催化剂和反应器组合，与最先进的技术相比，它可以以更低的蒸汽添加水平来管理高放热反应。通过应用研发，该项目将挑战催化剂的性能和工艺设计，并将采用以前未使用的新材料和工艺配置。该项目还将寻求将WGS反应的这些效率改进与新兴的气体分离技术相结合，以实现效益最大化。与最先进的技术相比，有针对性的逐步提高效率将减少一次燃料的使用，降低IGCC-CCS发电厂的成本，并降低使用e-WaGS技术的工厂生产低碳电力的成本。

Integrated Gasification Combined Cycle with CO2 Capture and Storage (IGCC-CCS) is a uniquely advantaged technology for the generation of low-carbon power since it produces hydrogen as a decarbonised fuel. The Water Gas Shift (WGS) reaction is a key step in the IGCC-CCS process in which carbon monoxide produced by the gasification of the fuel is reacted with steam to produce hydrogen and CO2. State-of-the-art technology involves a catalyst in a conventional fixed-bed reactor which needs a high level of excess steam to function correctly. The objective of this project is to find an innovative new catalyst and reactor combination which can manage the highly exothermic reaction with lower levels of steam addition compared to the state-of-the-art. Through applied R&D the project will challenge both the performance of catalyst and the design of the process and will apply new materials and process configurations not used previously. The project will also look to integrate these efficiency improvements in the WGS reaction with new emerging gas separation technologies to maximise benefits. The targeted step-change improvement in efficiency will deliver reduction in primary fuel use, reduce the cost of IGCC-CCS power plant and reduce the cost of low-carbon electric power generated by plant that use the e-WaGS technology compared to state-of-the-art technology.
