Aviation | Embraer, Hydrogen/Dual fuel Concepts

Hybrid-Electric Concepts:  

- Parallel hybrid electric powerplant, with next generation thermal engines and small electric engine employed to maximize thermal engine efficiency (take off & idle phases) 

- Propulsion electrification integrated with more electric aircraft systems 

- Small, cost-efficient battery 

 

Fuel Cell Concepts: 

- Fuel cell propulsion system, leading to a zero carbon, NOx and soot emissions, more efficient than small gas turbines, but heavier, and requires complex thermal management 

- Advanced propulsion installation with optimization strategies for fuel cell thermal management, reducing weight and drag 

 

Hydrogen/Dual fuel Concepts 

  • Hydrogen or dual fuel gas turbine engine 

  • If dual fuel: hydrogen used for typical missions and hydrogen liquid tanks (cryogenic) sized for the typical mission, while JetA/SAF used for range extension and reserves 

  • If Hydrogen only, hydrogen liquid tanks (cryogenic) sized for full range 

  • Zero carbon emissions, low NOx
