Fed. funding: $1.6M Length 24 mo. A Novel Hollow Fiber Membrane Reactor For High Purity H 2 Generation From Thermal Catalytic NH 3 Decomposition Miao Yu (PI), Rensselaer Polytechnic Institute Shiguang Li (co-PI), Gas Technology Institute Jochen Lauterbach (co-PI), University of South Carolina NH 3 Project Vision We are solving the challenge of high purity H 2 High production from NH 3 decomposition by designing a purity novel, self-sustained hollow fiber membrane reactor H 2 running at <450 o C. N 2 Project Impact The technology, if successful, is expected to solve H 2 transportation and storage problems by using NH 3 as an effective H 2 carrier for PEM fuel cell application, and may open potential markets utilizing H 2 as a fuel.
