Dr. Martine Rothblatt, the Chairperson and CEO of United Therapeutics, announced the successful lift-off of Proticity, the world's first hydrogen fuel cell-powered Robinson R44 helicopter. The milestone was reached at Roland-Désourdy Airport in Bromont, Quebec, Canada. The project's achievements were presented at the H2-Aero Symposium in Long Beach, California. United Therapeutics, known for its work in pulmonary arterial hypertension treatments and organ manufacturing, aims for carbon-neutral organ production and sustainable organ delivery. The company plans to use zero-emission vertical takeoff and landing aircraft for organ transportation. The hydrogen helicopter project, funded solely by United Therapeutics, received significant engineering support from the Robinson Helicopter Company. The prototype helicopter's technical setup includes a parallel hybrid fuel cell battery power plant, achieving a peak output of 178 kW. The company is working towards transitioning to a liquid hydrogen system for improved efficiency. The project also focuses on reducing noise pollution by using hydrogen propulsion, which generates less perceived noise. United Therapeutics is at the forefront of innovation in clean energy and sustainable aviation, with ambitious goals for the future.
