We cannot beat climate change without aviation being decarbonized. The aviation sector emits almost one billion tons of carbon dioxide (CO2) and by 2050, the commercial aircraft emissions are predicted to triple. Known approaches like SAF/Bio based fuels have limited replacement potential and Hydrogen combustion being at higher temperature is still a cause of NOx and contrails. Hydrogen as an aviation fuel is in for the long haul and is a true Zero emission on board solution. SiriNoR Co-Founder and CEO Abhijeet Inamdar shares roadmap highlights of the only known subsonic and supersonic jet engines for zero emission aviation based on a hydrogen-electric drivetrain. What commercial and technical barriers are ahead and where is SiriNoR seeking partners?
