Hydrogen internal combustion engine (ICE) vehicles present much of the same promise as hydrogen fuel cell vehicles (FCVs): reduced reliance on imported oil and reduced carbon dioxide emissions. Proponents envision hydrogen ICE as a bridging technology from gasoline vehicles to hydrogen FCVs. This paper examines the hydrogen ICE technology, focusing on relevant aspects such as power, fuel econom...

Abstract Green hydrogen has outgrown the testing stage: over next few years, consortia across Europe will be investing large sums to build supply chains of tomorrow. However, as a whole only successful if it aligns development with potentials its regions and exploits advantages European division labour. This article examines spatial distribution frontrunner projects in light regional heterogene...
