Aircraft Engine Makers Mostly Agnostic on Hydrogen

 - May 3, 2021, 8:30 AM MTU Aero Engines is working with German aerospace research agency DLR to develop a technology demonstrator to power a Dornier 228 aircraft with hydrogen. (Image: MTU Aero Engines) Much of the energy behind the growing momentum for hydrogen propulsion in aviation is now coming from start-up companies. Many of these have assembled small teams of well-educated, generally young engineers as they scramble to secure the investment they need to fuel their ambitious business plans. As their own cheerleaders, these companies generally are pre-disposed to emphasizing the positives around hydrogen, while portraying the potential negatives as solutions waiting to happen.
