What is it?
Methanol is synthesised directly from steam and carbon dioxide gas in a solid oxide electrolysis cell at elevated temperatures.
Why is it important?
Methanol can be synthesised directly from water and carbon dioxide, without requiring a precursory hydrogen production step. This reduces system complexity and could yield energy savings.
- Volumetric hydrogen density: 100kgH2/m3 at ambient conditions
- Gravimetric hydrogen density: 12.5% by mass
- Storage conditions: Liquid at ambient conditions
- Single reactor means reduced system complexity and lower associated capital costs
- Allows integration of waste heat streams, reducing the required energy input
- Makes use of carbon dioxide as a process input
- Balancing reactor temperature is a challenge. Methanol product decomposition occurs at typical solid oxide cell operating temperature
- Improve catalyst selectivity
- Develop cell designs and electrolytes capable of operating at thermodynamically favourable conditions
- Understand fundamental reaction mechanisms
- Validate proof of concept
