Introduction

There is great interest in converting electricity overcapacity, e.g. from renewables, to fuels such as hydrogen and synthetic gasoline or for the conversion of nitrogen to ammonia. Solid Oxide Electrolysis offers a high efficiency route to these conversions utilising technology similar to Solid Oxide Fuel Cells that have recently achieved commercial impact in the US and Japan at 100 kW and 1 kW scales, respectively. There are quite significant differences between electrolysis and fuel cell operation and fundamental aspects of electrolysis have received little attention. Thus, this is a topic of critical current interest that could yield a new clean chemical industry and indeed allow greater harvesting of renewables by storing excess in a more useful and higher energy density form than electricity.

Themes

  • Fundamental Electrochemistry
    Steam and carbon dioxide reduction – charge transfer, diffusion and migration. Use of high temperature oxide ion (500-1000°C) and intermediate temperature proton conductors (200-600°C). Oxygen evolution mechanistic studies. Nitrogen reduction especially at proton conductors.
  • Materials Development
    Performance optimisation through control of composition and microstructure. Development of new and improved electrocatalysts. Development of mixed electronic and ionic conducting materials.
  • Understanding durability
    Probing oxygen evolution and its influence on electrode spalling. Minimising chromium poisoning at anodes. Understanding ageing at high overpotentials and currents.
  • System studies
    Thermodynamic control to capitalise on process heat to optimise efficiency. Optimising different regimes such as autothermal, exothermic and endothermic for different chemical processes. Development of reversible fuel cell systems. Comparison between co-electrolysis of steam and carbon dioxide and electrolysis of steam to produce hydrogen to sequentially reduce carbon dioxide to syngas.

Aims

This meeting aims to bring together electrochemists, solid state chemists, materials scientists, catalysis chemists, and chemical engineers to discuss the fundamental aspects of solid oxide electrolysis.

We look forward to welcoming you to York for this Faraday Discussion.
