Carbon neutral H2ICE running on Hydrogen for sustainable long‑distance shipping

H4PERION

Hydrogen FOR Performance Enhancement and Reliable ICE OperatioN

The H4PERION project aims to accelerate the decarbonisation of large oceangoing vessels by developing a novel internal combustion engine (ICE) capable of running on biomethane and zero-carbon hydrogen fuel, with the potential for 100% hydrogen operation.

H4PERION is pronounced “hy-PEER-ee-on” — the “4” reads as a y — inspired by Hyperion, a Titan of Greek mythology.
