Membrane reactor for hydrogen production

Topic(s): Carbon capture use and storage (CCUS), CO₂ capture

This project aims to develop a catalytic membrane reactor (CMR), which intensifies hydrogen production processes and could lead to near-complete hydrogen conversion, purification and pre-combustion CO₂ capture in a single device.

During this reporting period, a membrane module with a surface area of 500 cm² was designed, constructed and tested. This represents a 250 fold increase in membrane surface area since the beginning of the project. Hydrogen flux has been consistently achieved at 40% of the US DOE flux target. With a minimal Pd consumption, this represents a competitive flux per capital cost ratio. Ongoing developments are also reported in the embrittlement-resistant vanadium alloy and the surface preparation procedure.
