As the automotive industry strives for reduced CO2 and navigates stringent emissions regulations, a promising alternative powertrain technology is emerging – the hydrogen internal combustion engine (H2-ICE).

Under ultra-lean operating conditions (Lambda >2,5), the H2-ICE produces almost no NOx emissions. This creates challenging requirements for the charging system but also allows the industry to offer ICE powertrain alternatives from their existing industrial base and supply chain at zero CO2 and ultra-low NOx tailpipe emissions.

In this free webinar, Firat Akar and Petr Pribyl of Garrett Motion explain how innovative turbo technologies can address each segment and group of applications by utilizing dedicated, high-efficiency aerodynamics in single or multistage systems and electrically-assisted boosting.

Key topics and takeaways:

• Explore the potential of different charging concepts under ultra-lean conditions for steady-state and transient operation
• Understand the demanding requirements on the compressor side and discover how Garrett is advancing turbo technologies to meet these challenges through high-efficiency aerodynamics and multistage machines
• Gain insight into the intricacies of optimizing the turbine system for hydrogen combustion engines, addressing the lower enthalpy available in exhaust gas compared to diesel engines of similar power density
• Learn about innovative electrically-assisted boosting solutions that harmonize with traditional methods, pushing the boundaries of H2-ICE performance and transient characteristics
