Universal Hydrogen successfully completes first flight of hydrogen fuel cell powered regional airliner

Green Car Congress

Universal Hydrogen has flown a 40-passenger regional airliner using hydrogen fuel cell propulsion. The airplane, nicknamed Lightning McClean, took off at 8:41am PST from Grant County International Airport (KMWH) and flew for 15 minutes, reaching an altitude of 3,500 MSL. The other remained a conventional engine for safety of flight.

Penn State, EC Power use internal thermal modulation to enable stable fast charging

Green Car Congress

A team from Penn State University and start-up EC Power has developed a material-agnostic technology based on asymmetric temperature modulation with a thermally stable dual-salt electrolyte to achieve stable fast charging for Li-ion batteries. Batteries operate most efficiently when they are hot, but not too hot.
