Advanced hydrogen production technologies

Conventional methane steam reforming technology face several challenges, such as low hydrogen purity (product separation requires extra energy and leads to product loss), reactors at different temperatures (heat integration and management are required), and catalyst deactivation (partial plant shutdown to recovery or change catalysts).

New technologies are developed with in situ hydrogen separation to increase the overall efficiency of the hydrogen plant. In our group, we focus on the following three technologies, i.e., membrane-supported water splitting, fuel-supported water electrolysis and chemical looping (redox) water splitting.

These three technologies can utilize carbon-free energy source such as solar energy to decrease the carbon footprint for hydrogen production.
