Green Hydrogen finds immense potential in decarbonizing aviation; aiming to advance research for transition.
Here’s an article posted in Arup that talks about Newzealand’s leap towards 100% renewable energy.
According to the article,
- New Zealand aims to transition to 100% renewable energy and become a global hub for advanced aviation and the aerospace industry.
- Green hydrogen is a key element in decarbonizing the transport sector.
- Pilot green hydrogen hubs at New Zealand airports provide a testbed to accelerate this transition.
So, what are the specific use cases for green hydrogen in aviation?
- Short-Haul Aircraft:
- Fuel Cells: Green hydrogen can power short-haul aircraft through fuel cells. These cells convert hydrogen into electricity, providing a zero-emission propulsion system.
- Direct Combustion: Hydrogen can also be directly burned in thermal (gas turbine) engines for short-range flights.
- Longer-Haul Aircraft:
- For larger airframes (such as those with 50 or more seats), liquid hydrogen is a viable option due to its higher energy density.
- Synthetic Liquid Fuels: Hydrogen can serve as a building block for synthetic liquid fuels, which can be blended with conventional jet fuel for longer-haul flights3.
- Ground Support Equipment:
- Beyond aircraft propulsion, green hydrogen can be used for ground support equipment at airports. This includes vehicles, tugs, and other machinery.
