To decrease the energy penalty of carbon capture and storage, we are developing thermally and chemically integrated systems for hydrogen separation using inorganic mixed ionic-electronic conducting (MIEC) membranes. These MIEC materials also have outstanding catalytic performances for water splitting and ammonia synthesis to achieve green hydrogen production.
Our group is also exploring renewable ammonia production technologies to reduce carbon emissions. Renewable ammonia can be used for energy storage, marine transportation, and sustainable agriculture.
Membrane-supported water splitting
An MIEC oxygen permeable membrane can be used to facilitate water splitting for clean hydrogen production. A schematic is shown here:
XiaoYu gave a talk on the membrane-supported water splitting technology for hydrogen production. The recording is here:
