Lightweight composite impellers for centrifugal hydrogen compression

Greene Tweed has been pursuing the development of a thermoplastic composite impeller, with the goal to use the higher strength-to-weight ratio of this class of materials to increase the rotational speeds of centrifugal impellers to achieve tip speeds of at least 600 m/s, which would enable the (re)compression of pure hydrogen. In the latest burst tests performed, a tip speed of 534 m/s was achieved, which is already far beyond the capability of similar closed metallic impellers.

In this webinar, Greene Tweed will expand upon the significant challenges of centrifugal hydrogen compression, and introduce the company’s innovative solution, as well as results from recent burst tests.
