Developments and scope for the use of hydrogen in future combustion engines

Abstract

With electrification still found wanting when it comes to heavier vehicles and modes of transportation, marine, rail and large commercial on- and off-highway applications are seen as the main applications where internal combustion engines (ICE) fed with non-fossil hydrocarbons and hydrogen (H2) can play an important role. Hydrogen IC engines can provide a durable, reliable, and cost-efficient solution based on well-known existing technology, contributing to a fast transition towards carbon-free mobility. The following view provides a summary of the main roles (and a few challenges) associated with H2ICE employment.
