“Green Hydrogen from the Next-generation High Temperature and Pressure Alkaline Electrolysis”

Electrolytic hydrogen production is a key in transitioning to a sustainable energy system, as it enables the production of sustainable fuels and chemicals from renewable electricity sources and a means to address their intermittent nature at the same time. Amongst the main electrolysis technologies, Alkaline Electrolysis (AE) is the most suitable for the hundreds of GW capacity that is required, as it relies only on abundant, low-cost materials, and has a proven record of reliability and scalability. However, AE suffers from poor efficiency and productivity. Increasing operating temperature and pressure offers a means to overcome this limitation. Nevertheless, electrodes and separators with good long-term stability in the hot corrosive alkaline environment are required. In addition, to investigate the electrochemical activity and stability of electrocatalysts and electrodes at high temperature and pressure (HTP) conditions, suitable reference electrodes (RE) are required to distinguish the contribution of individual electrodes. At present, there exists no commercial RE suitable for HTP operation. Even though we produce solutions to these primary challenges, the question remains how to develop a device level full cell/stack which can generate pressurized hydrogen?

In my presentation, I will talk about our research and solutions to the primary challenges associated with electrode stability and how we have designed a next generation HTP alkaline electrolysis cell testing facility at DTU Energy.
