Mitsubishi is teaming with ZeroAvia to convert regional airliners, such as the CRJ, to hydrogen propulsion. The Japanese group’s maintenance, repair, and overhaul subsidiary, MHI RJ Aviation Group (MHIRJ), said it will seek a supplemental type certificate (STC) to replace the GE Aviation CF-34 turbofans on the 50- to 100-seat twinjets with the hydrogen-electric powertrain that ZeroAvia is developing for multiple applications.
